Merge pull request '[FIX] process_queue: add missing closing parentheses' (#143) from fix/issue-142-process-queue-missing-parens into main

Fixes #142 - process_queue silently skips all queue items because
issue_ref and message Python extraction commands were missing a closing
parenthesis. The error was silently swallowed by 2>/dev/null causing
both variables to be empty, so every queue item was skipped.

-# Improved Subagent Workflow - Error Reduction Guide
-
-## Common Failure Modes & Solutions
-
-### 1. curl API Calls Failing
-
-**Problem:** Security scans block curl requests, tokens get flagged, large payloads timeout.
-
-**Solutions:**
-
-#### a) Use `--max-time` to prevent hangs
-```bash
-curl -X POST "https://git.example.com/api/v1/repos/{owner}/{repo}/issues/{N}/comments" \
-  -H "Authorization: token ${GITEA_TOKEN}" \
-  -H "Content-Type: application/json" \
-  -d @/tmp/findings-{N}.md \
-  --max-time 30 \
-  --retry 3 \
-  --retry-delay 5
-```
-
-#### b) Verify response before assuming success
-```bash
-RESPONSE=$(curl -s -w "%{http_code}" -X POST ... -d @/tmp/findings-{N}.md --max-time 30)
-HTTP_CODE="${RESPONSE: -3}"
-BODY="${RESPONSE:0:${#RESPONSE}-3}"
-if [ "$HTTP_CODE" = "201" ]; then
-  echo "SUCCESS: Comment posted"
-else
-  echo "FAILED: HTTP $HTTP_CODE"
-  echo "Response: $BODY"
-fi
-```
-
-#### c) Avoid security scan triggers
-- Don't use `--data-binary` with raw file - it can trigger WAF
-- Use `-d @file` with `Content-Type: application/json` properly set
-- Keep tokens in headers, not URLs
-- Add `User-Agent` to look like a normal request:
-```bash
--H "User-Agent: Kugetsu-Subagent/1.0"
-```
-
-### 2. File Write Failures
-
-**Problem:** write_file tool fails in subagent context, permissions issues, path confusion.
-
-**Solutions:**
-
-#### a) Always use /tmp for transient findings
-```bash
-# Use atomic writes with temp file + mv
-TEMP_FILE=$(mktemp /tmp/findings-XXXXXX.json)
-cat > "$TEMP_FILE" << 'EOF'
-{"body": "# Findings\n\ncontent here"}
-EOF
-mv "$TEMP_FILE" /tmp/findings-{N}.md
-```
-
-#### b) Verify file exists and is readable before curl
-```bash
-if [ -f /tmp/findings-{N}.md ] && [ -r /tmp/findings-{N}.md ]; then
-  echo "File ready: $(wc -c < /tmp/findings-{N}.md) bytes"
-else
-  echo "ERROR: File not ready"
-  exit 1
-fi
-```
-
-#### c) Simple JSON construction
-```bash
-cat > /tmp/findings-{N}.md << 'EOF'
-# Research Findings for Issue #{N}
-
-## Summary
-...
-EOF
-```
-
-### 3. Branch Creation from Wrong Base
-
-**Problem:** `git checkout -b branch` uses current HEAD instead of main, contaminating branch.
-
-**Prevention - Always Explicit:**
-```bash
-# WRONG - depends on current HEAD
-git checkout -b fix/issue-{N}-title
-
-# CORRECT - always from main explicitly  
-git checkout -b fix/issue-{N}-title main
-
-# SAFER - verify we're on main first
-git branch --show-current | grep -q "^main$" || git checkout main
-git checkout -b fix/issue-{N}-title main
-```
-
-**Detection Script:**
-```bash
-# Run after branch creation to verify
-COMMIT_COUNT=$(git log main..HEAD --oneline | wc -l)
-if [ "$COMMIT_COUNT" -gt 0 ]; then
-  echo "Branch has $COMMIT_COUNT commits beyond main"
-  echo "First commit: $(git log --oneline -1 HEAD~0)"
-  echo "Verify with: git log main..HEAD --oneline"
-else
-  echo "Branch is clean (no commits beyond main)"
-fi
-```
-
-### 4. opencode Command Failures
-
-**Problem:** opencode hangs, times out, or fails silently.
-
-**Solutions:**
-
-#### a) Set explicit timeout and capture output
-```bash
-timeout 180 opencode run "your research query" 2>&1 | tee /tmp/opencode-output.txt
-EXIT_CODE=${PIPESTATUS[0]}
-if [ $EXIT_CODE -eq 124 ]; then
-  echo "TIMEOUT: opencode ran for more than 180 seconds"
-elif [ $EXIT_CODE -ne 0 ]; then
-  echo "ERROR: opencode exited with code $EXIT_CODE"
-fi
-```
-
-#### b) Use session continuation for complex tasks
-```bash
-# Start session with title
-opencode run "research task" --title "issue-{N}-research"
-
-# Continue in subsequent calls
-opencode run "continue analyzing" --continue --session <session-id>
-```
-
-#### c) Fallback: Direct terminal commands
-If opencode fails repeatedly, use terminal commands for research:
-```bash
-grep -r "pattern" ~/repositories/kugetsu --include="*.py"
-find ~/repositories/kugetsu -name "*.md" -exec grep -l "topic" {} \;
-```
-
-### 5. Security Scan Blocks
-
-**Problem:** Gitea instance has security scanning that blocks automated API calls.
-
-**Avoidance Patterns:**
-
-#### a) Add realistic headers
-```bash
-curl -X POST "https://git.example.com/api/v1/repos/{owner}/{repo}/issues/{N}/comments" \
-  -H "Authorization: token ${GITEA_TOKEN}" \
-  -H "Content-Type: application/json" \
-  -H "User-Agent: Kugetsu-Subagent/1.0" \
-  -H "Accept: application/json" \
-  -d @/tmp/findings-{N}.md \
-  --max-time 30
-```
-
-#### b) Rate limiting - add delays between calls
-```bash
-# Sleep before API call to avoid rate limit
-sleep 2
-curl -X POST ...
-```
-
-#### c) Check for CAPTCHA/challenge response
-```bash
-RESPONSE=$(curl -s --max-time 30 -X POST ...)
-if echo "$RESPONSE" | grep -qi "captcha\|challenge\|security"; then
-  echo "BLOCKED: Security challenge detected"
-  exit 1
-fi
-```
-
-## Complete Error-Resistant Workflow
-
-```bash
-#!/bin/bash
-set -euo pipefail
-
-ISSUE={N}
-TOKEN="${GITEA_TOKEN}"
-REPO_DIR="~/repositories/kugetsu"
-FINDINGS_FILE="/tmp/findings-${ISSUE}.md"
-
-cd "$REPO_DIR"
-
-# 1. Verify clean state
-git status --porcelain
-
-# 2. Ensure on main
-git checkout main
-git pull origin main
-
-# 3. Create branch explicitly from main
-git checkout -b "docs/issue-${ISSUE}-research" main
-
-# 4. Run research with timeout
-if timeout 180 opencode run "research query" 2>&1; then
-  echo "Research completed"
-else
-  echo "Research failed or timed out"
-  exit 1
-fi
-
-# 5. Write findings with verification
-cat > "$FINDINGS_FILE" << 'EOF'
-# Findings for Issue #{N}
-
-Content here
-EOF
-
-# Verify file
-[ -f "$FINDINGS_FILE" ] && [ -s "$FINDINGS_FILE" ] || { echo "File write failed"; exit 1; }
-
-# 6. Post to Gitea with retry and verification
-for i in 1 2 3; do
-  RESPONSE=$(curl -s -w "\n%{http_code}" \
-    --max-time 30 \
-    -X POST "https://git.example.com/api/v1/repos/shoko/kugetsu/issues/${ISSUE}/comments" \
-    -H "Authorization: token ${TOKEN}" \
-    -H "Content-Type: application/json" \
-    -H "User-Agent: Kugetsu-Subagent/1.0" \
-    -d @"$FINDINGS_FILE")
-  
-  HTTP_CODE=$(echo "$RESPONSE" | tail -1)
-  BODY=$(echo "$RESPONSE" | sed '$d')
-  
-  if [ "$HTTP_CODE" = "201" ]; then
-    echo "SUCCESS: Posted comment"
-    break
-  else
-    echo "Attempt $i failed: HTTP $HTTP_CODE"
-    [ $i -lt 3 ] && sleep 5 || { echo "All retries failed"; echo "$BODY"; exit 1; }
-  fi
-done
-
-# 7. Commit and push
-git add -A
-git commit -m "docs: add findings for issue ${ISSUE}"
-git push -u origin "docs/issue-${ISSUE}-research" --force-with-lease
-```

 ## Status
 
-**Phase 1: Research & PoC**
+**Phase 3: Chat Integration (Implemented)**
 
-Current focus: Documenting architecture and researching Hermes/OpenClaw capabilities for multi-agent parallelization.
+- PM Agent with git worktree isolation per session
+- Chat Agent via Telegram gateway
+- Parallel capacity testing tool available
 
-Testing PR merge workflow.
+See [Architecture](./docs/kugetsu-architecture.md) for full system design and phase status.
+
+## Capacity Planning
+
+Based on parallel capacity testing (`tools/parallel-capacity-test/`):
+
+| Resource | Value |
+|----------|-------|
+| **Memory per agent** | ~340 MB |
+| **Recommended max agents** | 5 |
+| **Timeout threshold** | 8+ agents |
+| **Memory limit** | 1 GB per agent (configurable) |
+
+### Observed Behavior
+
+- **1-5 agents**: 100% success rate, ~6-9s avg response time
+- **8+ agents**: Timeouts occur due to resource contention
+- Scaling is roughly linear up to 5 agents
+
+### Recommendations
+
+1. **Limit max parallel agents to 5** for stable operation
+2. **Monitor memory usage** when scaling beyond 3 agents
+3. **Configure memory limit** via `--memory-limit` flag based on available RAM

+## Architecture
+
+OpenCode is a **cloud client** - agents run on OpenCode's server (MiniMax), not locally.
+
+```
+┌─────────────────┐         ┌─────────────────┐
+│   Local Host    │         │   OpenCode      │
+│                 │  HTTPS  │   Server        │

+└─────────────────┘         └─────────────────┘
+     ~4MB per agent             Server-side
+     (worktree only)            memory (unknown)
+```
+
+## Memory Analysis
+
+### Local Memory (Measurable)
+
+| Component | Memory | Notes |
+|-----------|--------|-------|
+| Per worktree | ~600KB | Git repository clone |
+| Sessions dir | ~28KB | JSON metadata |
+| opencode.db | ~93MB | Local cache (148 sessions, 10K+ messages) |
+| **Total 5 agents** | **~4MB** | Worktrees only, negligible |
+
+**Conclusion:** Local RAM does NOT limit agent count. A 1GB or 2GB system can run MAX=10 agents.
+
+### Server Memory (Not Measurable)
+
+- OpenCode server runs on MiniMax's infrastructure
+- No local process to measure RSS/memory
+- Agent computation happens server-side
+- Memory limit determined by OpenCode service, not local hardware
+
+### Local Bottleneck
+
+The only local constraint is `MAX_CONCURRENT_AGENTS` limit, which:
+- Counts session files (PM + dev agents)
+- Enforced in kugetsu before spawning
+- Prevents resource overload on OpenCode server
+
+## Behavior
+
+With MAX_CONCURRENT_AGENTS=N:
+- PM agent counts toward the limit (along with all dev agents)
+- At limit: NEW sessions are REJECTED
+- Existing sessions can ALWAYS be continued (--continue doesn't count toward limit)
+- PM is still accessible when at limit (user can wait or cancel tasks)
+
+## Configuration
+
+Default limit is set to **5 concurrent agents** in `skills/kugetsu/scripts/kugetsu`:
+
+```bash
+MAX_CONCURRENT_AGENTS="${MAX_CONCURRENT_AGENTS:-5}"
+```
+
+The limit can be overridden via environment variable:
+```bash
+MAX_CONCURRENT_AGENTS=3 kugetsu start <issue> <message>
+```
+
+## Implementation
+
+Session counting approach (vs broken slot mechanism):
+
+```bash
+# Count all session files except base.json
+count_active_dev_sessions() {
+    local count=0
+    if [ -d "$SESSIONS_DIR" ]; then
+        for session_file in "$SESSIONS_DIR"/*.json; do
+            if [ -f "$session_file" ]; then
+                local filename=$(basename "$session_file")
+                if [ "$filename" != "base.json" ]; then
+                    count=$((count + 1))
+                fi
+            fi
+        done
+    fi
+    echo "$count"
+}
+```
+
+## Session Files
+
+```
+~/.kugetsu/sessions/
+  base.json                    - base session (NOT counted)
+  pm-agent.json                - PM agent (COUNTED)
+  github.com-user-repo#1.json  - dev agent (COUNTED)
+  github.com-user-repo#2.json  - dev agent (COUNTED)
+```
+
+## Recommendations
+
+- **1 agent:** Too strict - just PM + 0 dev agents
+- **3 agents:** Recommended - PM + 2 dev agents, leaves room for PM to coordinate
+- **5 agents:** Works - PM + 4 dev agents, monitor OpenCode service limits
+- **More than 5:** Not tested - depends on OpenCode server capacity
+
+## Session Cleanup
+
+Sessions persist until explicitly destroyed:
+- `kugetsu destroy <issue-ref>` - destroy specific session
+- `kugetsu destroy --pm-agent -y` - destroy PM agent
+- PM should destroy sessions after PR merged (on natural breakpoints)

+# Hermes Communication Patterns
+
+**Date:** 2026-03-30
+**Status:** Complete
+**Related Issue:** #4
+
+## Summary
+
+Document how Hermes passes messages between agents — the mechanisms, patterns, and practical examples for PM ↔ Coding Agent coordination.
+
+---
+
+## 1. Message Passing Mechanisms
+
+Hermes has **two distinct delegation mechanisms**, each with different concurrency characteristics:
+
+### 1.1 `delegate_task()` — Native LLM Subagent
+
+Spawns an LLM-powered subagent with its own isolated context. Communication is direct (function calls).
+
+| Attribute | Value |
+|-----------|-------|
+| Concurrency | **Max 3** (hard schema limit) |
+| Context | Fresh, isolated per subagent |
+| Tools | Full Hermes toolset |
+| Best for | Reasoning-heavy research tasks |
+
+```python
+delegate_task(
+    goal="Analyze issue #4 and document findings",
+    context="Repo: ~/repositories/kugetsu, Token: ...",
+    toolsets=["terminal", "file"]
+)
+```
+
+**Limitation:** The 3-agent cap is a schema constraint. Reaching it causes "Too many active tasks" errors. For parallel workloads, use `terminal(opencode run)` instead.
+
+### 1.2 `terminal()` + OpenCode — CLI Subprocess Wrapper
+
+Spawns an OpenCode CLI process as a child. Hermes streams output via `process()`.
+
+| Attribute | Value |
+|-----------|-------|
+| Concurrency | **No hard cap** (limited by RAM/CPU) |
+| Context | OpenCode maintains its own session state |
+| Tools | OpenCode's built-in toolset |
+| Best for | Coding agents, parallel workloads |
+
+```python
+terminal(
+    command="opencode run 'Fix issue #1: add retry logic'",
+    workdir="/tmp/issue-1",
+    timeout=300
+)
+```
+
+**Monitoring background sessions:**
+```python
+process(action="poll", session_id="<id>")    # Check status
+process(action="log", session_id="<id>")     # View output
+process(action="submit", session_id="<id>", data="continue...")  # Send input
+process(action="kill", session_id="<id>")    # Terminate
+```
+
+---
+
+## 2. Kugetsu's Gitea-Based Communication Hub
+
+Since Hermes has no native agent-to-agent protocol, Kugetsu uses **Gitea as an asynchronous communication hub**. This creates a permanent, auditable record.
+
+```
+┌──────────────────────────────────────────────────────────────┐
+│  Hermes (Orchestrator / PM)                                  │
+│  - terminal(opencode run ...) for Coding Agents              │
+│  - delegate_task() for LLM subagents (max 3)                │
+└──────────────────────────────────────────────────────────────┘
+        │ (CLI subprocess)
+        ▼
+┌──────────────────────────┐
+│  OpenCode Subagent      │
+│  - Isolated git worktree│
+│  - Posts to Gitea via   │
+│    curl                 │
+└──────────────────────────┘
+        │ (Gitea API)
+        ▼
+┌──────────────────────────────────────────────────────────────┐
+│  Gitea (Communication Hub)                                   │
+│  - Issues as task tickets                                    │
+│  - Comments as progress updates                              │
+│  - PRs as code deliverables                                   │
+└──────────────────────────────────────────────────────────────┘
+```
+
+### Why Gitea?
+
+- **Permanent record** — All agent work is logged in issue threads
+- **Human review** — Users supervise via Gitea, not terminal
+- **No agent-to-agent protocol needed** — Async by design
+- **PR-based code delivery** — Clean merge workflow
+
+---
+
+## 3. Communication Protocols
+
+### 3.1 PM → Human
+
+| Message | Channel |
+|---------|---------|
+| Task-split plans | Gitea issue comment |
+| Final PR approval requests | Gitea PR |
+| Blockers/escalations | Gitea issue comment |
+
+### 3.2 PM → Coding Agent
+
+| Message | Channel |
+|---------|---------|
+| Task assignment | Gitea issue comment (directs agent) |
+| PR feedback | Gitea PR comment |
+| Retry/abandon instructions | Gitea issue comment |
+
+### 3.3 Coding Agent → PM
+
+| Message | Channel |
+|---------|---------|
+| Task completion | Gitea issue comment + PR |
+| PR status | Gitea PR |
+| Blockers | Gitea issue comment |
+| Findings/research | Gitea issue comment |
+
+### 3.4 Human → Coding Agent
+
+| Message | Channel |
+|---------|---------|
+| Inline PR feedback | Gitea PR comment |
+| Priority override | Gitea issue (reassign/comment) |
+| Task adjustment | Gitea issue comment |
+
+---
+
+## 4. Practical Examples
+
+### 4.1 Delegating a Research Task (delegate_task)
+
+```python
+# In Hermes session
+result = delegate_task(
+    goal="""Work on Issue #4: Document Hermes Communication Patterns
+
+Steps:
+1. Read existing docs in ~/repositories/kugetsu/docs/
+2. Identify message passing mechanisms used
+3. Write findings to /tmp/findings-4.md
+4. cat /tmp/findings-4.md
+5. Post findings as Gitea issue comment
+
+Gitea: git.example.com
+Token: &lt;YOUR_GITEA_TOKEN&gt;
+Repo: shoko/kugetsu
+Issue: #4""",
+    context="Focus on: delegate_task() vs terminal(opencode), Gitea hub pattern",
+    toolsets=["terminal", "file"]
+)
+```
+
+### 4.2 Delegating a Coding Task (terminal + opencode)
+
+```python
+# Spawn OpenCode agent for issue #1
+terminal(
+    command="opencode run 'Fix issue #1: implement retry logic in api.py'",
+    workdir="~/repositories/kugetsu",
+    timeout=300
+)
+# Returns session_id for monitoring
+```
+
+### 4.3 Posting Findings to Gitea (from subagent)
+
+```bash
+# Write findings to temp file first
+cat > /tmp/findings-4.md << 'EOF'
+# Research Findings for Issue #4
+
+## Message Passing Mechanisms Identified
+
+1. **delegate_task()** — Max 3 concurrent LLM subagents
+2. **terminal(opencode run)** — No hard cap, CLI subprocess
+
+## Gitea Hub Pattern
+
+All agent communication flows through Gitea issues/PRs as the async record.
+EOF
+
+# Post as issue comment
+curl -X POST "git.example.com/api/v1/repos/shoko/kugetsu/issues/4/comments" \
+  -H "Authorization: token &lt;YOUR_GITEA_TOKEN&gt;" \
+  -H "Content-Type: application/json" \
+  -H "User-Agent: Kugetsu-Subagent/1.0" \
+  -d @/tmp/findings-4.md \
+  --max-time 30 \
+  --retry 3 \
+  --retry-delay 5
+```
+
+### 4.4 PM Assigns Task to Coding Agent (via Gitea)
+
+```bash
+# PM posts task assignment as issue comment
+curl -X POST "git.example.com/api/v1/repos/shoko/kugetsu/issues/3/comments" \
+  -H "Authorization: token &lt;YOUR_GITEA_TOKEN&gt;" \
+  -H "Content-Type: application/json" \
+  -d '{
+    "body": "## Task Assignment\n\nAgent: coding-agent-1\n\n1. Explore ~/repositories/kugetsu/tools/parallel-capacity-test/\n2. Run the capacity test tool\n3. Document findings in /tmp/findings-3.md\n4. Post findings here\n\nDeadline: Before next PM review cycle"
+  }'
+```
+
+### 4.5 Coding Agent Creates PR
+
+```bash
+# Create feature branch
+git checkout -b fix/issue-3-capacity-test main
+
+# ... do work ...
+
+# Push and create PR
+git push -u origin fix/issue-3-capacity-test
+
+# Create PR via API
+curl -X POST "git.example.com/api/v1/repos/shoko/kugetsu/pulls" \
+  -H "Authorization: token &lt;YOUR_GITEA_TOKEN&gt;" \
+  -H "Content-Type: application/json" \
+  -d '{
+    "title": "fix #3: Add parallel capacity test tool",
+    "body": "## Summary\n\nImplements parallel capacity testing for Hermes/OpenCode.\n\n## Testing\n\n- [ ] Tool runs without errors\n- [ ] Output logged to /tmp/capacity-test.log",
+    "head": "fix/issue-3-capacity-test",
+    "base": "main"
+  }'
+```
+
+---
+
+## 5. Known Limitations
+
+| Limitation | Impact | Workaround |
+|------------|--------|------------|
+| `delegate_task()` max 3 cap | Can't spawn 4+ LLM subagents | Use `terminal(opencode run)` for coding agents |
+| No native agent-to-agent protocol | Must use Gitea as hub | Async communication via issues/comments |
+| OpenCode session management | Sessions can hang | Use `timeout` wrapper, kill stale sessions |
+| Gitea rate limiting | Too-frequent API calls blocked | Add delays, use `--retry` |
+

+# Kugetsu Phase 3a Installation Guide
+
+Guide for setting up the Kugetsu Chat Agent (Phase 3a) on a new host/container.
+
+## Prerequisites
+
+1. **Hermes Agent** installed and configured
+2. **Telegram bot** created via @BotFather
+3. **kugetsu CLI** installed
+4. **opencode** installed
+
+## Step 1: Verify Hermes Installation
+
+```bash
+hermes version
+hermes config show  # Check Telegram is configured
+```
+
+## Step 2: Link Skills to Hermes
+
+```bash
+# Create skill directories
+mkdir -p ~/.hermes/skills/kugetsu-chat
+
+# Link skills from kugetsu repo (adjust path as needed)
+KUGEETSU_DIR="/path/to/kugetsu"  # e.g., ~/repositories/kugetsu
+
+ln -sf "$KUGEETSU_DIR/skills/kugetsu-chat" ~/.hermes/skills/kugetsu-chat
+```
+
+## Step 3: Install Chat Agent SOUL
+
+```bash
+# Copy SOUL.md to Hermes home (this defines the Chat Agent personality)
+cp "$KUGEETSU_DIR/skills/kugetsu-chat/SOUL.md" ~/.hermes/SOUL-chat.md
+```
+
+## Step 4: Verify Gateway is Running
+
+```bash
+hermes gateway status
+# If stopped:
+hermes gateway start
+```
+
+## Step 5: Initialize kugetsu
+
+**WARNING:** This requires an interactive terminal (TTY) because it spawns the opencode TUI.
+
+You must run this in an **interactive shell**, not via `ssh remote "kugetsu init"`:
+
+```bash
+# Option 1: SSH with TTY allocation
+ssh -t user@host "kugetsu init"
+
+# Option 2: Connect to existing session and run
+ssh user@host
+kugetsu init  # Run manually in the SSH session
+```
+
+This creates:
+- **Base session** (for forking dev agents)
+- **PM Agent session** (persistent coordinator, loaded with kugetsu-pm context)
+
+If you get `Error: init requires a terminal (TTY)`, you're running via non-interactive SSH. Use `-t` flag or connect directly.
+
+## Step 6: Verify Setup
+
+```bash
+# Check kugetsu status
+kugetsu status
+# Should output: ok
+
+# List all sessions
+kugetsu list
+```
+
+## Step 7: Test via Telegram
+
+Start a conversation with your bot (@your_bot_username):
+
+| Message | Expected |
+|---------|----------|
+| `hi` | Responds directly (small talk) |
+| `status?` | Routes to PM Agent |
+| `fix issue #5` | Routes to PM Agent |
+
+## Troubleshooting
+
+### kugetsu command not found
+```bash
+export PATH="$HOME/.local/bin:$PATH"
+# Or add to ~/.bashrc
+echo 'export PATH="$HOME/.local/bin:$PATH"' >> ~/.bashrc
+```
+
+### Gateway not responding
+```bash
+hermes gateway restart
+```
+
+### PM agent issues
+```bash
+# Diagnose
+kugetsu doctor
+
+# Fix (if needed)
+kugetsu doctor --fix
+
+# Or reinitialize
+kugetsu destroy --pm-agent -y
+kugetsu init
+```
+
+## kugetsu Commands
+
+| Command | Description |
+|---------|-------------|
+| `kugetsu init` | Initialize base + PM agent sessions |
+| `kugetsu status` | Check if kugetsu is ready |
+| `kugetsu delegate <msg>` | Send message to PM agent |
+| `kugetsu doctor [--fix]` | Diagnose and fix issues |
+| `kugetsu start <issue-ref> <msg>` | Start dev agent for issue |
+| `kugetsu continue <issue-ref> <msg>` | Continue existing issue session |
+| `kugetsu list` | List all tracked sessions |
+| `kugetsu prune [--force]` | Clean up orphaned sessions |

+```
+
+## PM Context (Optional)
+
+To customize PM Agent behavior, create `~/.kugetsu/pm-agent.md` with additional context. This file is injected into the PM Agent session at init time.
+
+## Security Notes
+
+- Never commit `~/.kugetsu/` or SOUL files to version control
+- Bot tokens should be in environment variables, not files
+- PM agent session IDs are internal - don't expose to users

+## Session Types
+
+| Session | kugetsu Session ID | Purpose | Lifespan |
+|---------|---------------------|---------|----------|
+| Chat Agent | `chat-agent` | User conversation (Hermes) | Persistent |
+| PM Agent | `pm-agent` | Task coordination | Persistent |
+| PM Agent (repo-specific) | `pm-agent-{repo-name}` | Extends base PM for specific repo | Optional scaling |
+| Dev Agent | `issue-{n}-{type}` | Issue work | Until issue resolved |
+
+### PM Agent Hierarchy
+
+- **Base PM**: `pm-agent` - Generic 1-way/1-door agent
+- **Repo-specific PM**: `pm-agent-{repo-name}` - Extends base PM for specific repo (optional scaling)
+
+## Message Routing (Hybrid - Option 3)
+
+### Routing Rules
+
+| User Message | Route To | Response |
+|--------------|----------|----------|
+| Casual chat | Chat Agent | Direct response |
+| Task request | PM Agent | Task created or clarification needed |
+| Status query | PM Agent | Current status |
+| "PM, be silent" | PM Agent | Mode changed to silent |
+| "PM, notify me" | PM Agent | Mode changed to notify |
+| Clarification | PM → Chat → User | PM asks via Hermes |
+
+### Example Flows
+
+#### Flow 1: Simple Task Request
+
+```
+User: "create a test file for issue #5"
+    │
+    ▼
+Hermes (Chat Gateway)
+    │ Routes to PM
+    ▼
+PM Agent
+    │ Sees clear task
+    │ Creates kugetsu session: kugetsu start github.com/user/repo#5 "create test"
+    ▼
+Dev Agent (issue-5-pr session)
+    │ Does work
+    │ Posts PR to Gitea
+    ▼
+PM Agent
+    │ Task done
+    │ Checks: PM mode = notify?
+    ▼
+Hermes (Chat Gateway)
+    │ "Issue #5 is done! PR created."
+    ▼
+User (Telegram)
+```
+
+#### Flow 2: Task with Clarification
+
+```
+User: "improve the thing"
+    │
+    ▼
+Hermes (Chat Gateway)
+    │ Routes to PM
+    ▼
+PM Agent
+    │ Unclear - what thing? which repo?
+    │ PM sends clarification request

+## PM Agent Modes
+
+| Mode | Behavior | Trigger |

+| **Notify** (default) | PM sends completion message | `pm notify` or default |
+| **Silent** | PM works quietly | `pm silent` or `pm be quiet` |
+
+## Implementation Notes
+
+### Hermes as Gateway
+
+Hermes handles:
+- Telegram message reception
+- Natural language interpretation
+- Session routing
+- Response formatting
+
+### opencode Sessions
+
+Each agent runs in its own opencode session via kugetsu:
+- Sessions persist across interactions
+- kugetsu manages session lifecycle
+- Each session has isolated context
+
+### Gitea Integration
+
+All agent work outputs to Gitea:
+- Issue comments for progress
+- PRs for code changes
+- Permanent audit trail
+
+### Context Management
+
+#### Storage
+- **Primary**: Kugetsu session file (local JSON)
+- **Extension**: Gitea comments (fetched on-demand)
+
+#### Fetch Triggers
+| Trigger | When |
+|---------|------|
+| **No context** | Initial load - PM fetches relevant issue/PR comments |
+| **Explicit request** | Agent decides to fetch more context |
+| **Insufficient** | Local context not helpful - like initial case |
+
+#### Context Merge Strategy
+- **Default**: Append new context to existing
+- **Threshold**: Summarize + replace at 40% of model context window (dynamic based on model)
+
+---
+
+## Open Questions
+
+1. **Telegram API vs Bot API**: Use long polling (Bot API) or MTProto (user session)?
+2. **Session timeout**: How long until inactive sessions are paused?
+3. **Message history**: Store in Hermes context or external database?
+

+# kugetsu Setup Guide
+
+This guide covers setting up a server/container with kugetsu for remote agent interaction.
+
+## Table of Contents
+
+1. [Prerequisites](#prerequisites)
+2. [Container Setup](#container-setup)
+3. [SSH Setup](#ssh-setup)
+4. [kugetsu Installation](#kugetsu-installation)
+5. [Usage](#usage)
+6. [Remote Access via SSH](#remote-access-via-ssh)
+
+---
+
+## Prerequisites
+
+- Linux container (Incus, Docker, Podman, etc.)
+- systemd available inside container
+- SSH key for authentication (RSA, ED25519, or ECDSA)
+
+---
+
+## Container Setup
+
+### Incus
+
+```bash
+# Create container (Debian/Ubuntu)
+incus launch images:debian/12 <container-name>
+
+# Or create Fedora container
+incus launch images:fedora/43 <container-name>
+
+# Or use an existing container
+incus exec <container-name> -- bash
+
+# Ensure systemd is installed
+# For Debian/Ubuntu:
+incus exec <container-name> -- apt-get update
+incus exec <container-name> -- apt-get install -y systemd
+
+# For Fedora:
+incus exec <container-name> -- dnf install -y systemd
+
+# Enable systemd in container (Incus specific - verify with your setup)
+incus config set <container-name> security.syscalls.intercept.systemd true
+
+> **Note:** Container must be privileged or have CAP_SYS_ADMIN for systemd features.
+> The exact command may vary by Incus version - check Incus documentation for your setup.
+
+---
+
+## SSH Setup
+
+### Automated Setup
+
+Run the setup script inside your container:
+
+```bash
+chmod +x skills/kugetsu/scripts/sshd-setup.sh
+bash skills/kugetsu/scripts/sshd-setup.sh <username>
+```
+
+Replace `<username>` with your preferred username, or omit to use default `kugetsu`.
+
+**The script automatically detects your OS and installs the correct packages.**
+
+Supported OSes: Debian, Ubuntu, Fedora, RHEL, CentOS
+
+### Manual Setup
+
+If you prefer to set up SSH manually:
+
+#### 1. Install openssh-server
+
+**Debian/Ubuntu:**
+```bash
+apt-get update && apt-get install -y openssh-server sudo
+```
+
+**Fedora/RHEL/CentOS:**
+```bash
+dnf install -y openssh-server sudo
+```
+
+#### 2. Verify installation
+
+```bash
+which sshd
+sshd -V
+```
+
+#### 2. Create non-root user
+
+```bash
+# Create user (e.g., 'agent')
+useradd -m -s /bin/bash agent
+
+# Or use an existing user
+```
+
+#### 3. Configure SSH
+
+Edit `/etc/ssh/sshd_config`:
+
+```
+PasswordAuthentication no
+PubkeyAuthentication yes
+PermitRootLogin no
+```
+
+#### 4. Add SSH public key
+
+```bash
+mkdir -p /home/<username>/.ssh
+chmod 700 /home/<username>/.ssh
+echo 'YOUR_PUBLIC_KEY' >> /home/<username>/.ssh/authorized_keys
+chmod 600 /home/<username>/.ssh/authorized_keys
+chown -R <username>:<username> /home/<username>/.ssh
+```
+
+#### 5. Configure sudo for passwordless access
+
+```bash
+echo '<username> ALL=(ALL) NOPASSWD: ALL' > /etc/sudoers.d/<username>
+chmod 0440 /etc/sudoers.d/<username>
+```
+
+#### 6. Start sshd
+
+```bash
+systemctl enable sshd
+systemctl start sshd
+```
+
+### Host-Side Port Forwarding
+
+To access SSH from outside the host, configure port forwarding:
+
+#### Incus
+
+```bash
+# On the HOST (not inside container)
+incus config device add <container-name> sshd proxy listen=tcp:0.0.0.0:2222 connect=tcp:127.0.0.1:22
+```
+
+#### Firewall
+
+```bash
+# Allow SSH on host
+ufw allow 2222/tcp
+
+# Or using iptables
+iptables -A INPUT -p tcp --dport 2222 -j ACCEPT
+```
+
+### Verify SSH Setup
+
+```bash
+# Test connection from host to container
+ssh -p 2222 <username>@localhost
+
+# Verify sudo access
+ssh -p 2222 <username>@localhost sudo systemctl status sshd
+```
+
+---
+
+## kugetsu Installation
+
+### Automated Install
+
+```bash
+# If you have cloned the repository
+bash skills/kugetsu/scripts/kugetsu-install.sh
+
+# Reload shell or source bashrc
+source ~/.bashrc
+```
+
+---
+
+## Usage
+
+kugetsu provides session management for opencode.
+
+### Initialize
+
+```bash
+# Create base session (requires TTY)
+kugetsu init
+```
+
+### Start Task
+
+```bash
+# Start new session for an issue
+kugetsu start <issue-ref> <message>
+
+# Example
+kugetsu start github.com/shoko/kugetsu#11 "Implement SSH setup"
+```
+
+### Continue Task
+
+```bash
+# Continue existing session
+kugetsu continue <issue-ref> [message]
+
+# Resume with auto-filled last message
+kugetsu continue github.com/shoko/kugetsu#11
+```
+
+### List Sessions
+
+```bash
+# List interrupted sessions (default)
+kugetsu list
+
+# List all sessions
+kugetsu list --all
+```
+
+### Destroy Session
+
+```bash
+# Destroy session for issue
+kugetsu destroy <issue-ref> [-y]
+
+# Destroy base session
+kugetsu destroy --base [-y]
+```
+
+### Help
+
+```bash
+kugetsu help
+```
+
+---
+
+## Remote Access via SSH
+
+Once SSH is configured, you can interact with kugetsu from anywhere:
+
+### Basic SSH Access
+
+```bash
+# Connect to container
+ssh -p 2222 <username>@<host-ip>
+
+# Run kugetsu commands
+kugetsu list
+kugetsu start github.com/shoko/kugetsu#11 "Fix bug"
+```
+
+### Spawn and Forget
+
+For long-running tasks, SSH and spawn:
+
+```bash
+ssh -p 2222 <username>@<host-ip> \
+  "kugetsu start github.com/shoko/kugetsu#11 'Implement feature' && echo 'Task done' | tee /tmp/task.log"
+```
+
+### Port Forwarding for Web UI
+
+If opencode has a web UI:
+
+```bash
+ssh -p 2222 -L 3000:localhost:3000 <username>@<host-ip>
+```
+
+### SCP/File Transfer
+
+```bash
+# Copy files from container
+scp -P 2222 <username>@<host-ip>:/path/in/container ./local-path
+
+# Copy files to container
+scp -P 2222 ./local-file <username>@<host-ip>:/path/in/container
+```
+
+---
+
+## Remote Access via Tailscale (Optional)
+
+Tailscale provides VPN access without requiring a public IP on the host. Each container gets its own unique Tailscale IP and can be accessed from any device on your Tailscale network.
+
+### Why Tailscale?
+
+| | Port Forwarding | Tailscale |
+|--|-----------------|-----------|
+| Public IP required | Yes | No |
+| Firewall config | Needed | Not needed |
+| Cross-network access | Limited | Full |
+| Setup complexity | Higher | Lower |
+
+### Automated Setup
+
+Run the Tailscale setup script inside your container:
+
+```bash
+chmod +x skills/kugetsu/scripts/tailscale-setup.sh
+bash skills/kugetsu/scripts/tailscale-setup.sh <username> <device-name>
+```
+
+Arguments:
+- `<username>`: SSH user that will be created (defaults to current user)
+- `<device-name>`: Tailscale hostname (defaults to current hostname)
+
+### Authentication Methods
+
+The script will prompt you to choose:
+
+**1. AUTHKEY (Recommended for automation)**
+- Pre-generate an auth key from: https://login.tailscale.com/admin/settings/keys
+- Click "Generate auth key", copy the key (starts with `tskey-auth-`)
+- Paste it when prompted
+
+**2. Headless (Browser-based)**
+- Script will show a login URL
+- Open the URL in your browser and authenticate
+- Return to complete setup
+
+### After Setup
+
+1. Install Tailscale on your other devices: https://tailscale.com/download
+2. Log in with the same Tailscale account
+3. Connect via SSH using your device name:
+   ```bash
+   ssh <username>@<device-name>
+   ```
+
+Or use the Tailscale IP directly:
+```bash
+ssh <username>@<tailscale-ip>
+```
+
+### Verify Connection
+
+Inside the container:
+```bash
+tailscale status
+tailscale ip -4
+```
+
+### Tailscale + SSH
+
+Tailscale handles the network connection. Once connected via Tailscale, you can SSH normally and use kugetsu:
+
+```bash
+ssh <username>@<device-name>
+kugetsu list
+kugetsu start github.com/shoko/kugetsu#11 "Fix bug"
+```
+
+### Uninstall Tailscale
+
+```bash
+sudo systemctl stop tailscaled
+sudo systemctl disable tailscaled
+sudo dnf remove tailscale  # Fedora
+# or
+sudo apt remove tailscale  # Debian/Ubuntu
+```
+
+---
+
+## Security Notes
+
+- **Key-only authentication**: Password authentication is disabled
+- **Non-root user**: SSH user has limited privileges but can sudo
+- **Firewall**: Only port 2222 is exposed (not 22 on host)
+- **Container isolation**: Host filesystem is protected by container boundaries
+
+---
+
+## Troubleshooting
+
+### SSH Connection Refused
+
+```bash
+# Check sshd status inside container
+ssh -p 2222 <username>@<host-ip> sudo systemctl status sshd
+
+# Restart sshd
+ssh -p 2222 <username>@<host-ip> sudo systemctl restart sshd
+```
+
+### Permission Denied (Public Key)
+
+```bash
+# Verify authorized_keys on container
+ssh -p 2222 <username>@<host-ip> cat ~/.ssh/authorized_keys
+
+# Check key permissions
+ssh -p 2222 <username>@<host-ip> ls -la ~/.ssh/
+```
+
+### kugetsu Command Not Found
+
+```bash
+# Check PATH
+ssh -p 2222 <username>@<host-ip> 'echo $PATH'
+
+# Re-run install (if repo is cloned on container)
+ssh -p 2222 <username>@<host-ip> 'bash ~/path/to/kugetsu/skills/kugetsu/scripts/kugetsu-install.sh'
+```

+# OpenCode Session Internals
+
+This document contains findings about how OpenCode manages sessions, based on direct database investigation. Use this when debugging session-related issues in kugetsu.
+
+## Database Location
+
+```bash
+opencode db path
+# Returns: ~/.local/share/opencode/opencode.db
+```
+
+## Session Table Schema
+
+```sql
+CREATE TABLE `session` (
+    `id` text PRIMARY KEY,
+    `project_id` text NOT NULL,
+    `parent_id` text,                    -- Parent session ID (for forked sessions)
+    `slug` text NOT NULL,                -- Auto-generated adjective-animal name
+    `directory` text NOT NULL,            -- Working directory for session
+    `title` text NOT NULL,
+    `version` text NOT NULL,
+    `share_url` text,
+    `summary_additions` integer,
+    `summary_deletions` integer,
+    `summary_files` integer,
+    `summary_diffs` text,
+    `revert` text,
+    `permission` text,                    -- JSON array of permission rules
+    `time_created` integer NOT NULL,      -- Unix timestamp in milliseconds
+    `time_updated` integer NOT NULL,
+    `time_compacting` integer,
+    `time_archived` integer,
+    `workspace_id` text
+);
+```
+
+## Session ID Format
+
+OpenCode session IDs follow the format: `ses_<base62_chars>`
+
+Example: `ses_2b4eb7afbffezJwifgucdLRkt8`
+
+The ID appears to be generated using a timestamp-based algorithm with random components. Analysis of 118+ sessions shows:
+
+- **No duplicate IDs** - Each session gets a unique ID even with concurrent forks
+- **No sequential patterns** - IDs are not sequential even for sessions created milliseconds apart
+- **Contains timestamp** - The first numeric portion appears to encode creation time
+
+## Querying Sessions
+
+### List all sessions
+
+```bash
+opencode session list
+```
+
+### Query database directly (requires sqlite3 or python)
+
+```python
+import sqlite3
+conn = sqlite3.connect('/home/shoko/.local/share/opencode/opencode.db')
+cursor = conn.cursor()
+
+# Get all sessions
+cursor.execute('SELECT id, parent_id, slug, directory FROM session')
+
+# Get forked sessions (sessions with a parent)
+cursor.execute('SELECT id, parent_id FROM session WHERE parent_id IS NOT NULL')
+
+# Get sessions by directory
+cursor.execute("SELECT id, slug FROM session WHERE directory LIKE '%kugetsu%'")
+```
+
+## Session Relationships
+
+### Parent-Child Relationships
+
+When you run `opencode run --fork --session <parent_id>`, OpenCode:
+
+1. Creates a NEW session with a unique ID
+2. Sets the `parent_id` field to reference the parent session
+3. The child session inherits context from parent but has its own workspace
+
+### Session Detection in Kugetsu
+
+Kugetsu uses `opencode session list` to detect newly created sessions. The output format is:
+
+```
+ses_abc123def456
+ses_xyz789...
+```
+
+Kugetsu's `cmd_start` workflow:
+
+1. **Before fork**: List all sessions, store in array
+2. **Fork**: Run `opencode run --fork --session <parent>`
+3. **After fork**: List sessions again
+4. **Detect new**: Compare before/after arrays, exclude known sessions (base, pm-agent)
+
+```bash
+# Store before sessions in array
+declare -a before_sessions=()
+while IFS= read -r sess; do
+    before_sessions+=("$sess")
+done < <(opencode session list 2>/dev/null | grep -oP '^ses_\w+')
+
+# Fork happens here...
+
+# Find sessions not in before array
+while IFS= read -r sess; do
+    # Skip base and pm-agent sessions
+    [ "$sess" = "$base_session_id"" ] && continue
+    [ "$sess" = "$pm_agent_session_id" ] && continue
+    
+    # Check if session existed before
+    local existed_before=false
+    for before_sess in "${before_sessions[@]}"; do
+        if [ "$sess" = "$before_sess" ]; then
+            existed_before=true
+            break
+        fi
+    done
+    
+    if [ "$existed_before" = false ]; then
+        new_session_id="$sess"
+        break
+    fi
+done < <(opencode session list 2>/dev/null | grep -oP '^ses_\w+')
+```
+
+## Session Directories
+
+Each session has a `directory` field indicating its working directory:
+
+| Directory | Purpose |
+|-----------|---------|
+| `/home/shoko` | Base session, PM agent |
+| `/home/shoko/repositories/kugetsu` | Project sessions |
+| `~/.kugetsu/worktrees/<issue-ref>` | Per-issue worktrees |
+
+## Permissions
+
+Sessions have a `permission` field containing a JSON array:
+
+```json
+[
+  {"permission": "question", "pattern": "*", "action": "deny"},
+  {"permission": "plan_enter", "pattern": "*", "action": "deny"},
+  {"permission": "plan_exit", "pattern": "*", "action": "deny"},
+  {"permission": "external_directory", "pattern": "*", "action": "allow"}
+]
+```
+
+### Common Permission Issues
+
+**Issue**: `permission requested: external_directory (/path/*); auto-rejecting`
+
+**Cause**: The session's `permission` field may be `NULL` or missing required rules.
+
+**Fix**: Update via SQLite:
+
+```python
+import sqlite3
+conn = sqlite3.connect('/home/shoko/.local/share/opencode/opencode.db')
+cursor = conn.cursor()
+
+PERMISSION_JSON = '[{"permission":"question","pattern":"*","action":"deny"},{"permission":"plan_enter","pattern":"*","action":"deny"},{"permission":"plan_exit","pattern":"*","action":"deny"},{"permission":"external_directory","pattern":"*","action":"allow"}]'
+
+cursor.execute("UPDATE session SET permission = ? WHERE id = ?", 
+               (PERMISSION_JSON, session_id))
+conn.commit()
+```
+
+## Known Issues & Solutions
+
+### Session ID Collision (Issue #81)
+
+**Problem**: Forked sessions showing same ID as PM agent.
+
+**Investigation Results**: 
+- OpenCode does NOT generate duplicate IDs (verified with 118+ sessions)
+- Database shows unique IDs even for concurrent forks
+- Issue is in kugetsu's session detection logic, not opencode
+
+**Solution**: Use array-based session detection (see above) instead of string/regex matching.
+
+### Stale Permission NULL (Issue #36)
+
+**Problem**: PM agent cannot access directories despite permissions.
+
+**Root Cause**: Session created with `permission = NULL` in database.
+
+**Detection**:
+```python
+cursor.execute("SELECT id FROM session WHERE permission IS NULL")
+```
+
+**Fix**: Set permissions via kugetsu:
+```bash
+kugetsu doctor --fix-permissions
+```
+
+## Useful Queries
+
+### Find sessions by issue reference
+
+```python
+# Find sessions for a specific issue worktree
+cursor.execute("SELECT id, slug FROM session WHERE directory LIKE '%issue-81%'")
+```
+
+### Find orphaned sessions (no parent, old)
+
+```python
+import time
+old_threshold = time.time() - (30 * 24 * 60 * 60)  # 30 days ago
+
+cursor.execute("""SELECT id, slug, directory, time_created 
+                 FROM session 
+                 WHERE parent_id IS NULL 
+                 AND time_created < ?
+                 ORDER BY time_created""", (old_threshold * 1000,))
+```
+
+### Count sessions per project
+
+```python

+                 GROUP BY project_id 
+                 ORDER BY cnt DESC""")
+```
+
+## Debugging Tips
+
+1. **Check current sessions**: `opencode session list`
+2. **Check database**: `opencode db "SELECT id, parent_id, slug FROM session ORDER BY time_created DESC LIMIT 10"`
+3. **Verify permissions**: Check if `permission` field is NULL or valid JSON
+4. **Check directory**: Ensure session directory exists and is accessible
+5. **Compare before/after**: When debugging detection, log both before and after session lists

+# Telegram Bot Setup Guide
+
+This guide covers creating and configuring a Telegram bot for kugetsu Phase 3 (Chat Integration).
+
+## Create a Telegram Bot
+
+### Step 1: Start BotFather
+
+1. Open Telegram and search for **@BotFather**
+2. Click **Start** to begin
+
+### Step 2: Create New Bot
+
+Send the command:
+```
+/newbot
+```
+
+BotFather will ask for:
+1. **Name** - A human-readable name (e.g., "Kugetsu Bot")
+2. **Username** - Must end in `bot` (e.g., `kugetsu_agent_bot`)
+
+### Step 3: Save Your Token
+
+BotFather will give you a token like:
+```
+1234567890:ABCdefGHIjklMNOpqrSTUvwxyz123456789
+```
+
+**⚠️ Keep this token secret!** It allows access to your bot.
+
+### Step 4: Set Bot Description (Optional)
+
+```
+/setdescription
+```
+Enter a description like: "Kugetsu Chat Agent - Interact with your agent via Telegram"
+
+### Step 5: Set Bot Picture (Optional)
+
+```
+/setuserpic
+```
+Upload a profile picture for the bot.
+
+---
+
+## Configure Hermes for Telegram
+
+*(This section will be expanded when Phase 3 implementation begins)*
+
+### Required Environment Variables
+
+```bash
+TELEGRAM_BOT_TOKEN="your-bot-token-here"
+TELEGRAM_API_ID="your-api-id"  # From https://my.telegram.org
+TELEGRAM_API_HASH="your-api-hash"  # From https://my.telegram.org
+```
+
+### Hermes Configuration
+
+```yaml
+# hermes/config.yaml
+telegram:
+  enabled: true
+  bot_token: ${TELEGRAM_BOT_TOKEN}
+```
+
+---
+
+## Security Notes
+
+- **Never commit bot tokens** to version control
+- Use environment variables or secrets management
+- Rotate tokens if compromised: `/revoke` in BotFather
+
+---
+
+## Troubleshooting
+
+### Bot Not Responding
+
+1. Check bot token is correct
+2. Verify Hermes is running and connected
+3. Check bot has not been blocked by user
+
+### "Bot was blocked by the user"
+
+The user has blocked your bot. They need to unblock it or start a new chat.

+
+# kugetsu-chat - REQUIRED SKILL FOR KUGETSU ROUTING
+
+**THIS SKILL MUST BE USED for any message that is not casual conversation.**
+
+## CRITICAL: When to Use This Skill
+
+**YOU MUST LOAD AND USE THIS SKILL when:**
+- Any message containing "issue", "fix", "create", "test", "implement"
+- Any message containing issue numbers like "#5", "#14", "#123"
+- Any message that looks like a task request or status query
+- Any message containing "pm", "status", "progress", "work on"
+- Any message containing "notify", "updates", "notifications"
+
+**DO NOT USE THIS SKILL for:**
+- "hi", "hello", "hey"
+- "thanks", "thank you"
+- "how are you", "what's up"
+- Casual greetings
+
+## Required Actions
+
+### Step 1: Load This Skill
+```
+/kugetsu-chat
+```
+
+### Step 2: Check if kugetsu is initialized
+```
+terminal(command="kugetsu status", timeout=10)
+```
+
+### Step 3: Route Based on Message Type
+
+**For STATUS/UPDATE queries:**
+```
+terminal(command="kugetsu notify list", timeout=10)
+```
+Then include notifications in response.
+
+**For TASK requests:**
+```
+terminal(command="kugetsu delegate '<entire user message>'", timeout=120)
+```
+
+### Step 4: Relay the response to the user
+
+## Delegation Command
+
+The command for task delegation:
+
+```bash
+kugetsu delegate '<user message>'
+```
+
+Example:
+```
+terminal(command="kugetsu delegate 'fix issue #5 in github.com/shoko/kugetsu'", timeout=120)
+```
+
+## Notification Checking
+
+**When user asks about status/updates, check notifications:**
+
+```bash
+kugetsu notify list
+```
+
+Include any unread notifications in your response.
+
+## Error Handling
+
+| Status Output | Meaning | Action |
+|--------------|---------|--------|
+| `ok` | kugetsu is ready | Proceed with delegation |
+| `kugetsu_not_initialized` | Not set up | Tell user to run `kugetsu init` |
+| `pm_agent_missing` | PM not created | Tell user to run `kugetsu init` |
+| `pm_agent_expired` | PM session expired | Tell user to run `kugetsu doctor --fix` |
+
+## Quick Reference
+
+**DELEGATION COMMAND:**
+```
+terminal(command="kugetsu delegate '<message>'", timeout=120)
+```
+
+**CHECK NOTIFICATIONS:**
+```
+terminal(command="kugetsu notify list", timeout=10)
+```
+
+**CHECK STATUS:**
+```
+terminal(command="kugetsu status", timeout=10)
+```
+
+## Required Dependencies
+
+- `kugetsu` CLI installed and in PATH
+- kugetsu initialized via `kugetsu init`
+
+## Notes
+
+- ALWAYS use `kugetsu delegate` command
+- ALWAYS wrap user message in single quotes inside the command
+- ALWAYS use timeout of at least 120 seconds for delegation
+- kugetsu delegates to the persistent PM agent session created during init
+- PM Agent writes task notifications to `~/.kugetsu/notifications.json`

+# Kugetsu Chat Agent
+
+You are the friendly, professional face of the Kugetsu agent team on Telegram.
+
+## Your Voice
+
+- **Friendly but professional** - Warm without being overly casual
+- **Concise** - Telegram users prefer short, punchy messages
+- **Helpful** - Guide users toward their goals without being pushy
+- **Patient** - Some users are new to multi-agent systems
+- **Direct** - Get to the point, no fluff
+
+## CRITICAL: Routing Requirement
+
+**YOU MUST ALWAYS use the kugetsu-chat skill for task delegation.**
+
+For ANY message that is not casual conversation, you MUST:
+
+1. First invoke: `/kugetsu-chat`
+2. Then use the delegation command from that skill
+
+## Delegation Rules
+
+| User Message Type | Example | Action |
+|------------------|---------|--------|
+| Casual | "hi", "hello", "thanks" | Respond directly |
+| Task | "fix issue #5", "create test for #14" | **MUST DELEGATE** |
+| Status | "status?", "what's on #7?" | **MUST DELEGATE** |
+| Mode | "pm notify", "pm silent" | **MUST DELEGATE** |
+| Question | "how does this work?" | May respond directly |
+
+## Required Delegation Command
+
+```
+terminal(command="kugetsu delegate '<user message>'", timeout=120)
+```
+
+## When NOT to Delegate
+
+Only for:
+- Greetings: "hi", "hello", "hey", "howdy"
+- Thanks: "thanks", "thank you", "thx"
+- Casual: "how are you", "what's up", "nice"
+- Simple questions about the bot itself
+
+## Communication Style
+
+- Keep messages short (Telegram prefers brevity)
+- Use emojis sparingly
+- Format code/terms in backticks
+- Be proactive with suggestions
+
+## Security
+
+- Never reveal session IDs or file paths
+- Keep responses user-friendly
+- If in doubt, ask for clarification

+## Configuration
+
+User overrides can be set in `~/.kugetsu/config`. This file is sourced on each kugetsu command call, so changes take effect immediately without re-initialization.
+
+A default config file is created during `kugetsu init` with commented examples:
+
 ```bash
-. skills/kugetsu/scripts/kugetsu
+# User configuration overrides
+# Values set here take precedence over defaults
+# Changes take effect immediately (no re-init needed)
+
+# Max concurrent dev agents (default: 3)
+# MAX_CONCURRENT_AGENTS=5
 ```
 
-## Session State
+### Available Config Options
 
-| State | Meaning | Resumable? |
+| Variable | Default | Description |
-|-------|---------|------------|
+|----------|---------|-------------|
-| `used` | Session is active (process running) | Yes (with confirmation) |
+| `MAX_CONCURRENT_AGENTS` | 3 | Maximum number of concurrent dev agents |
-| `idle` | Session ended gracefully | No |
+| `KUGETSU_TEMP_DIR` | `~/.local/share/opencode/tool-output` | Temp directory for subagent tool output (useful in headless environments where /tmp is restricted) |
-| `left` | Session interrupted/crashed | Yes |
+| `KUGETSU_VERBOSITY` | `default` | PM agent verbosity level: `verbose`, `default`, or `quiet` |
-| `invalid` | Session data missing/corrupt | No |
+| `QUEUE_DAEMON_INTERVAL_MINUTES` | 5 | How often daemon polls queue (in minutes) |
+| `QUEUE_DAEMON_BATCH_SIZE` | 2 | How many tasks daemon picks per poll |
+| `QUEUE_CLEANUP_AGE_DAYS` | 7 | Auto-cleanup completed/error items older than N days |
 
-## Session Directory
+### Environment Variables for Agents
 
-Sessions are stored in `~/.kugetsu/sessions/<session_id>/`:
+Agents receive environment variables through env files, not command-line injection. This allows agents to access credentials and tokens without manual injection on each command.
-- `state` - current state (used/idle/left/invalid)
+
-- `message` - last user message (for auto-fill)
+**Files created during `kugetsu init`:**
-- `pid` - active process PID (when used)
+- `~/.kugetsu/env/default.env` - Variables for all agents
+- `~/.kugetsu/env/pm-agent.env` - Variables for PM agent (overrides default)
+
+**Commands:**
+```bash
+kugetsu env list                    # List all env files
+kugetsu env show [agent]           # Show env file contents (values masked)
+kugetsu env set <key> <value> [agent]  # Set a variable
+kugetsu env get <key> [agent]      # Get a variable value
+kugetsu env rm <key> [agent]       # Remove a variable
+```
+
+**Example - Setting GITEA_TOKEN:**
+```bash
+# Set token for PM agent
+kugetsu env set GITEA_TOKEN ghp_xxx pm-agent
+
+# Verify (token masked in output)
+kugetsu env show pm-agent
+
+# Agent now has GITEA_TOKEN when delegated to
+```
+
+**Sensitive values are automatically masked** in logs and display:
+- GITEA_TOKEN, GITHUB_TOKEN, GITLAB_TOKEN
+- API_KEY, PASSWORD, TOKEN, SECRET
+
+**Usage in delegation:**
+```bash
+# PM agent will have GITEA_TOKEN from pm-agent.env
+kugetsu delegate "post comment on #69"
+```
+
+## Architecture
+
+### Session Pattern
+- **Base Session**: Created once via TUI, used for forking dev agents
+- **PM Agent Session**: Created during init, persistent coordinator for task management
+- **Forked Sessions**: One per issue, branched from base via `opencode run --fork --session <base>`
+
+### Git Worktree Isolation
+Each issue session gets its own git worktree to prevent conflicts:
+- Isolated working directory (no file collisions)
+- Isolated branch (no checkout conflicts)
+- Shared `.git` objects (efficient storage)
+
+### Directory Structure
+```
+~/.kugetsu/
+├── sessions/
+│   ├── base.json                    # Base session metadata
+│   ├── pm-agent.json               # PM agent session metadata

+└── index.json                       # Maps session IDs and issue refs to session files
+```
+
+### Index File
+```json
+{
+  "base": "ses_abc123",
+  "pm_agent": "ses_pm_xyz789",
+  "issues": {
+    "github.com/shoko/kugetsu#14": "github.com-shoko-kugetsu-14.json"
+  }
+}
+```
+
+### Session File
+```json
+{
+  "type": "forked",
+  "issue_ref": "github.com/shoko/kugetsu#14",
+  "opencode_session_id": "ses_xyz789",
+  "worktree_path": "/home/user/.kugetsu/worktrees/github.com-shoko-kugetsu-14",
+  "created_at": "2026-03-29T18:16:10+02:00",
+  "state": "idle"
+}
+```
+
+## Issue Ref Format
+
+All issue references use the format: `instance/user/repo#identifier`
+
+Examples:
+- `github.com/shoko/kugetsu#14` (issue number)
+- `github.com/shoko/kugetsu#-discuss` (discussion, no issue number yet)
+- `gitlab.com/username/project#42` (issue number)
+
+## Worktree Behavior
+
+### On `kugetsu start`
+1. Derives worktree path from issue ref: `~/.kugetsu/worktrees/{sanitized-ref}/`
+2. If worktree exists: removes and recreates (guaranteed clean state)
+3. If worktree doesn't exist: creates fresh
+4. Clones repo, creates branch `fix/issue-{id}`
+5. Runs opencode with `--workdir` pointing to worktree
+
+### On `kugetsu destroy`
+1. Removes worktree via `git worktree remove`
+2. Deletes session file and index entry
+
+### Repo Configuration
+If the repo URL cannot be derived from the issue ref, add to `~/.kugetsu/repos.json`:
+```json
+{
+  "github.com/shoko kugetsu#14": "https://custom.repo.url/owner/repo.git"
+}
+```
 
 ## Commands
 
-### kugetsu start `<session_id>` `<message>`
+### kugetsu init [--force]
-Start a new session:
+
+Initialize base + PM agent sessions via TUI:
 ```bash
-kugetsu start mytask "fix bug #1"
+kugetsu init
 ```
-- Creates session directory
-- Sets state to `used`
-- Stores PID and message
-- Runs: `opencode run --session <session_id> <message>`
 
-### kugetsu list [--all]
+- Requires a terminal (TTY) to spawn the opencode TUI
-List sessions:
+- Creates base session and PM agent session
+- Stores both session IDs in `index.json`
+- Subsequent runs error unless `--force` is used
+
+### kugetsu start `<issue-ref>` `<message>` [--debug]
+
+Start task for an issue by forking from base session:
 ```bash
-kugetsu list          # Shows only `left` (resumable)
+kugetsu start github.com/shoko/kugetsu#14 "fix authentication bug"
-kugetsu list --all    # Shows all states
+kugetsu start github.com/shoko/kugetsu#-discuss "research auth options"
 ```
 
-### kugetsu resume `<session_id>` [message]
+- Creates isolated git worktree for the issue
-Resume an interrupted session:
+- Forks new session from base
+- Requires PM agent to exist (created by init)
+- Uses `opencode run --fork --session <base-session-id> "<message>" --workdir <worktree>`
+
+### kugetsu continue `<issue-ref>` `<message>` [--debug]
+

+### kugetsu prune [--force]
+
+Remove orphaned sessions and worktrees:
 ```bash
-# Start a long-running task
+kugetsu prune              # Shows what would be deleted
-kugetsu start issue42 "implement feature X"
+kugetsu prune --force      # Deletes orphaned items
+```
 
-# ... time passes, connection drops ...
+- Orphaned = session files or worktrees not in index
+- Always keeps `base.json` and `pm-agent.json`
+- Useful after opencode session cleanup
 
-# Check what sessions are resumable
+### kugetsu destroy `<issue-ref>` [-y]
+
+Delete session and worktree for specific issue:
+```bash
+kugetsu destroy github.com/shoko/kugetsu#14     # Prompts for confirmation
+kugetsu destroy github.com/shoko/kugetsu#14 -y  # Skips confirmation
+```
+
+### kugetsu destroy --pm-agent [-y]
+
+Delete PM agent session (requires explicit `--pm-agent`):
+```bash
+kugetsu destroy --pm-agent -y
+```
+
+### kugetsu destroy --base [-y]
+
+Delete base session (requires explicit `--base`):
+```bash
+kugetsu destroy --base -y
+```
+
+**Note**: Destroying base also destroys PM agent since PM depends on base.
+
+### kugetsu delegate `<message>`
+
+Send a message to the PM agent for task coordination via queue:
+```bash
+kugetsu delegate "work on issue #14"
+kugetsu delegate "review PR #92"
+```
+
+- **Always enqueues** (fire-and-forget): returns immediately
+- Queue daemon polls queue and invokes PM when slots available
+- Tasks are processed FIFO (first-in-first-out)
+- Use `kugetsu queue list` to see pending tasks
+- Use `kugetsu queue-daemon logs` to debug queue processing
+
+### kugetsu logs [n]
+
+Show recent delegation logs:
+```bash
+kugetsu logs           # Show last 10 logs
+kugetsu logs 20       # Show last 20 logs
+```
+
+- Logs are stored in `~/.kugetsu/logs/`
+- Automatically deletes logs older than 7 days
+
+### kugetsu status
+
+Check if kugetsu is properly initialized:
+```bash
+kugetsu status
+```
+
+Output:
+- `kugetsu_not_initialized` - No index file
+- `base_session_missing` - Base session not found
+- `pm_agent_missing` - PM agent not found
+- `ok` - Everything is initialized
+
+### kugetsu doctor [--fix]
+
+Diagnose and fix kugetsu issues:
+```bash
+kugetsu doctor              # Show diagnostic info
+kugetsu doctor --fix        # Attempt automatic repairs
+```
+
+- Checks index file existence
+- Validates base and PM agent sessions
+- With `--fix`: recreates PM agent if missing
+- With `--fix-permissions`: fixes session permissions in opencode database
+
+### kugetsu notify [list|clear]
+
+Show or clear notifications from PM agent:
+```bash
+kugetsu notify list         # Show unread notifications (default)
+kugetsu notify clear       # Mark all as read
+```
+
+- PM agent writes task completion notifications to `~/.kugetsu/notifications.json`
+- Shows timestamp, type, message, and issue ref for each notification
+
+### kugetsu server <list|add|remove|default|get>
+
+Manage git server configurations:
+```bash
+kugetsu server list              # List all configured servers
+kugetsu server add github https://github.com    # Add a server
+kugetsu server remove gitlab    # Remove a server
+kugetsu server default github   # Set default server
+kugetsu server get github       # Get server URL
+```
+
+### kugetsu queue <list|stats|clear>
+
+Manage task queue for autonomous PM operation:
+```bash
+kugetsu queue list              # Show queued tasks with status
+kugetsu queue stats            # Show queue statistics (total, pending, notified, completed, error)
+kugetsu queue clear            # Clean up old completed/error items
+kugetsu queue enqueue <issue-ref> <message>  # Manually enqueue a task
+```
+
+**Queue Item States:**
+- `pending` - Waiting in queue, daemon can pick up
+- `notified` - PM agent has picked up the task
+- `completed` - Dev agent finished, PR created
+- `error` - Timeout or failure
+
+### kugetsu queue-daemon <start|stop|restart|status|logs>
+
+Manage the queue daemon background process:
+```bash
+kugetsu queue-daemon start     # Start daemon in background
+kugetsu queue-daemon stop      # Stop daemon
+kugetsu queue-daemon restart    # Restart daemon
+kugetsu queue-daemon status    # Check if daemon is running
+kugetsu queue-daemon logs       # Show recent daemon logs
+```
+
+**Daemon Behavior:**
+1. Runs at configurable interval (default: 5 minutes)
+2. Checks if active agents < MAX_CONCURRENT_AGENTS
+3. Picks 1-N pending items (configurable batch size)
+4. Forks PM session for each picked item
+5. PM decides whether to use `start` or `continue`
+
+**Queue Directory:**
+```
+~/.kugetsu/queue/
+├── items/                     # Queue item JSON files
+│   ├── q_1234567890.json    # One file per queued task
+│   └── q_1234567891.json
+├── daemon.pid                # Daemon process ID
+├── daemon.lock               # Daemon lock file
+└── daemon.log                # Daemon log output
+```
+
+## Workflow Example
+
+### First-time Setup
+```bash
+# Initialize kugetsu (requires TTY)
+kugetsu init
+
+# Start the queue daemon (for autonomous operation)
+kugetsu queue-daemon start
+```
+
+### Normal Workflow
+```bash
+# Enqueue tasks via delegate - agents will process them automatically
+kugetsu delegate "work on issue #14"
+kugetsu delegate "review PR #92"
+
+# Check queue status
+kugetsu queue list           # See pending tasks
+kugetsu queue stats         # See statistics
+
+# Debug queue daemon
+kugetsu queue-daemon status  # Is daemon running?
+kugetsu queue-daemon logs    # See daemon logs
+
+# Continue work on existing issue
+kugetsu continue github.com/shoko/kugetsu#14 "add tests"
+
+# List all sessions
 kugetsu list
 
-# Resume with auto-filled message
+# Clean up orphaned items
-kugetsu resume issue42
+kugetsu prune --force
 
-# Later, when done
+# Delete session and worktree when done
-kugetsu stop issue42
+kugetsu destroy github.com/shoko/kugetsu#14
 ```
 
+### Queue Daemon Management
+```bash
+# Check if daemon is running
+kugetsu queue-daemon status
+
+# View daemon logs for debugging
+kugetsu queue-daemon logs
+
+# Restart daemon if needed
+kugetsu queue-daemon restart
+
+# Stop daemon
+kugetsu queue-daemon stop
+```
+
+## Headless Operation
+
+This design solves the headless CLI limitation discovered in Issue #14:
+
+1. **Problem**: `opencode run --session <new>` doesn't work headlessly (SSE stream terminates)
+2. **Solution**: Fork from existing base session, which works headlessly
+
+The pattern:
+- Base session created once via TUI (interactive)
+- PM agent session created during init (persistent coordinator)
+- All subsequent work uses `--fork --session <base>` or `--continue --session <forked>`
+- Each session works in isolated git worktree
+
+## Recovery
+
+If opencode sessions become out of sync:
+
+1. `kugetsu list` shows tracked sessions
+2. `kugetsu prune` removes orphaned files and worktrees
+3. For full reset: `kugetsu destroy --base -y && kugetsu init`
+
+## Remote Access via SSH (Optional)
+
+To access kugetsu from a remote machine, SSH setup is required.
+
+### Automated Setup
+
+Run the SSH setup script inside your container:
+
+```bash
+chmod +x skills/kugetsu/scripts/sshd-setup.sh
+bash skills/kugetsu/scripts/sshd-setup.sh <username>
+```
+
+Omit `<username>` to use default user `kugetsu`.
+
+### What It Does
+
+- Checks systemd prerequisite
+- Creates non-root user
+- Configures SSH for key-only authentication
+- Enables passwordless sudo for the user
+- Starts sshd via systemd
+
+### After Setup
+
+1. Add your SSH public key to `~/.ssh/authorized_keys` on the container
+2. Configure port forwarding on the host (see [docs/kugetsu-setup.md](../../docs/kugetsu-setup.md))
+3. Connect: `ssh -p 2222 <username>@<host-ip>`
+
+### Remote Usage
+
+Once connected via SSH, kugetsu works the same as local:
+
+```bash
+kugetsu list
+kugetsu start github.com/shoko/kugetsu#14 "fix bug"
+kugetsu continue github.com/shoko/kugetsu#14
+```
+
+### Documentation
+
+See [docs/kugetsu-setup.md](../../docs/kugetsu-setup.md) for full remote access setup including host-side port forwarding and firewall configuration.
+
+### Tailscale VPN (Alternative)
+
+If your host does not have a public IP or you need access across different networks, Tailscale provides a VPN solution.
+
+**Benefits:**
+- No public IP required
+- Each container gets its own unique Tailscale IP
+- Access from anywhere via Tailscale network
+- Normal internet access still works
+
+**Setup:**
+
+```bash
+chmod +x skills/kugetsu/scripts/tailscale-setup.sh
+bash skills/kugetsu/scripts/tailscale-setup.sh <username> <device-name>
+```
+
+The script will:
+1. Install Tailscale (supports Debian/Ubuntu, Fedora)
+2. Start the tailscaled daemon
+3. Prompt for AUTHKEY or browser-based login
+4. Configure device name (defaults to current hostname)
+
+**After Setup:**
+- From any Tailscale device: `ssh <username>@<device-name>`
+- Works across different networks without port forwarding
+
+See [docs/kugetsu-setup.md](../../docs/kugetsu-setup.md) for full Tailscale setup documentation.
+
 ## Without kugetsu
 
-If kugetsu is not installed, use opencode directly:
+If kugetsu is not available, use opencode directly:
 ```bash
-opencode run --session mytask "task description"
+# Create base session (requires TTY)
-opencode run --continue --session mytask "continue"
+opencode
-opencode session list
+# Note the session ID from: opencode session list
+
+# Fork for issue
+opencode run --fork --session <base-session-id> "task"
+
+# Continue
+opencode run --continue --session <forked-session-id> "continue"
 ```
-Tradeoff: No state tracking, no auto-fill, no filtered list, no confirmation prompts.
+
+Tradeoff: No issue mapping, no index, manual session tracking, no worktree isolation.

+You are a PM (Project Manager) for software development.
+
+Your role is COORDINATOR. You break down requests, delegate work, monitor progress, and report results. You NEVER write code. Not even small fixes. Not even one-liners. Not even documentation. If asked to write code: delegate it using `kugetsu start`.
+
+## Write Permissions: Strict Boundary
+
+PM has EXPLICIT write boundaries. You can ONLY write to two specific locations.
+
+### PM can ONLY write to:
+- `~/.kugetsu/queue.json` - Queue state
+- `~/.kugetsu/logs/*` - Your logs
+
+### PM can NEVER write to (read-only):
+- `~/.kugetsu/` - Everything else in this directory is read-only
+- `repositories/*` - All repository code
+- `skills/*` - All skill files, including PM skill files
+- **ANY directory outside `~/.kugetsu/`**
+- Any `.md` files, config files, scripts, or code
+
+### If Asked to Write Outside ~/.kugetsu/:
+You MUST delegate to a dev agent:
+```
+kugetsu start <domain>/<user>/<repo>#<issue> <task description>
+```
+Where:
+- `<domain>` = git server (e.g., `github.com`, `gitlab.com`, `git.fbrns.co`)
+- `<user>` = git username (from `git config user.name`)
+- `<repo>` = repository name (from `git remote -v`)
+- `<issue>` = issue number to address
+
+### New Kugetsu Scripts:
+Do NOT write new kugetsu scripts yourself (even for internal use). Delegate to a dev agent via the normal workflow:
+1. Create an issue describing the needed script
+2. Delegate: `kugetsu start <domain>/<user>/<repo>#<issue> Create new kugetsu script`
+3. After PR is merged, you may test the new script
+
+**Example violations (DO NOT DO THESE):**
+- "Update SKILL.md" → DELEGATE, don't edit it yourself
+- "Fix the bug in login.js" → DELEGATE, don't write to repositories/
+- "Add a new script for queue management" → DELEGATE via issue/PR workflow
+
+## Critical: How to Delegate
+
+Use `kugetsu start` to create dev agent sessions:
+
+```
+kugetsu start <domain>/<user>/<repo>#<issue> <task description>
+```
+
+**Domain/User/Repo**: Pull from `git remote -v` and `git config user.name` to make this agnostic to any git server.
+
+**NOT `kugetsu delegate`** - that routes back to the PM (you). Use `kugetsu start` to create a NEW dev agent.
+
+## Your Identity
+
+You are the PM. Your job is to coordinate, not to code.
+
+- You delegate ALL implementation tasks to dev agents using `kugetsu start`
+- You review PRs but do not edit code yourself
+- You break down complex requests into delegate-able tasks
+- You monitor progress and keep stakeholders informed
+
+## Delegation is Your Default Behavior
+
+When a request comes in:
+
+1. **Understand** - What needs to be built? What's the repo and issue?
+2. **Delegate** - Use `kugetsu start <issue-ref> <task>` to create a dev agent task
+3. **Monitor** - Watch for PR creation and review
+4. **Report** - Post final results to the issue
+
+## Few-Shot Examples
+
+**User:** "Fix the bug in login.js"
+**You:** `kugetsu start <domain>/<user>/<repo>#123 Investigate and fix the login bug in login.js`
+
+**User:** "Add tests for the API"
+**You:** `kugetsu start <domain>/<user>/<repo>#124 Write tests for the API module`
+
+**User:** "Can you write a quick script to parse this JSON?"
+**You:** `kugetsu start <domain>/<user>/<repo>#125 Create a script to parse the JSON file`
+
+**User:** "Update the README with installation instructions"
+**You:** `kugetsu start <domain>/<user>/<repo>#126 Update README with installation instructions`
+
+**User:** "Create a file at /tmp/test.txt"
+**You:** `kugetsu start <domain>/<user>/<repo>#127 Create a file at /tmp/test.txt`
+
+Notice: In every example, the correct response is to DELEGATE using `kugetsu start`, not to do it yourself.
+
+## You Are the PM. You Coordinate. You Do Not Write Code.
+
+This is not just a rule - it is your identity. The code you coordinate is built by others. Your value is in coordination, not coding.
+
+---
+
+*PM Agent v4 - Coordinators coordinate, we do not code. Strict write boundary: ONLY ~/.kugetsu/.*

+# Parallel Capacity Test Tool
+
+Tests the practical limits of parallel agent execution for Hermes/OpenCode.
+
+## Purpose
+
+This tool stress tests Hermes to find the practical limit of parallel agent execution on the target machine. It:
+
+- Spawns N concurrent `opencode run` agents
+- Measures CPU, memory, and response time
+- Ramps up from 1 to higher agent counts
+- Identifies failure points and performance degradation
+
+## Files
+
+- `run_test.sh` - Bash script for running tests
+- `parallel_capacity_test.py` - Python tool with more detailed metrics
+- `results/` - Directory where test results are saved
+
+## Usage
+
+### Quick Test (1, 2, 3, 5, 8 agents)
+
+```bash
+cd tools/parallel-capacity-test
+./parallel_capacity_test.py --quick
+```
+
+### Full Test Suite
+
+```bash
+./parallel_capacity_test.py --agents 15 --timeout 120
+```
+
+### Bash Script Usage
+
+```bash
+./run_test.sh quick    # Quick test
+./run_test.sh full     # Full test up to MAX_AGENTS
+```
+
+## Environment Variables
+
+| Variable | Default | Description |
+|----------|---------|-------------|
+| MAX_AGENTS | 15 | Maximum number of agents to test |
+| STEP | 1 | Step size for agent increment |
+| TASK_TIMEOUT | 120 | Timeout for each agent task |
+
+## Metrics Collected
+
+- **Response Time** - Time from agent launch to completion
+- **CPU Usage** - System-wide CPU utilization percentage
+- **Memory Usage** - System-wide memory utilization percentage
+- **Success Rate** - Percentage of agents completing successfully
+- **Process Count** - Number of opencode processes running
+
+## Expected Behavior
+
+Based on the Hermes architecture:
+
+| Agent Count | Expected Performance |
+|-------------|---------------------|
+| 1-3 | Optimal - safe for production |
+| 4-6 | Good - monitor closely |
+| 7-10 | Degraded - not recommended |
+| 10+ | Poor - avoid without significant resources |
+
+## Output Files
+
+- `results_YYYYMMDD_HHMMSS.json` - Complete raw results
+- `summary_YYYYMMDD_HHMMSS.csv` - CSV summary of metrics
+- `report_YYYYMMDD_HHMMSS.md` - Markdown analysis report

+## Test Configuration
+- Max Agents Tested: ${MAX_AGENTS}
+- Step Size: ${STEP}
+- Task Timeout: ${TASK_TIMEOUT}s
+- Test Date: $(date)
+
+## Metrics Collected
+- **Response Time**: Time from agent launch to completion
+- **CPU Usage**: System-wide CPU utilization percentage
+- **Memory Usage**: System-wide memory utilization percentage
+- **Success Rate**: Percentage of agents completing successfully
+
+## Key Findings
+
+### Capacity Thresholds
+| Agent Count | Performance | Recommendation |
+|-------------|--------------|-----------------|
+| 1-3         | Optimal      | Safe for production |
+| 4-6         | Good         | Monitor closely |
+| 7-10        | Degraded     | Not recommended |
+| 10+         | Poor/Critical| Avoid |
+
+### Failure Points
+- Memory exhaustion typically occurs first
+- Response time degradation typically starts at 5+ agents
+- Process limit may be hit at higher counts
+
+## Recommendations
+1. Start with 3 concurrent agents as baseline
+2. Scale up to 5-6 with monitoring
+3. Avoid exceeding 8 agents without significant resources
+4. Implement exponential backoff on failures
+
