fix: remove obsolete slot-based concurrency mechanism

The session-counting approach (PR #65) now properly handles agent
concurrency limits. Remove the broken slot-based mechanism:

- Remove acquire_agent_slot() and release_agent_slot() functions
- Remove AGENT_COUNT_FILE and AGENT_LOCK_FILE variables
- Remove unused run_with_limit() function
- Remove release-slot.sh script
- Update cmd_delegate to use fire-and-forget without slot management

Both cmd_start and cmd_delegate now use count_active_dev_sessions()
for concurrency checking.

+# Agent Concurrency Benchmark
+
+**Date:** 2026-04-01  
+**Hardware:** 8GB RAM, 16 CPU cores
+
+## Test Results
+
+| Limit (PM+Dev) | Status | Rejection Test | Notes |
+|----------------|--------|---------------|-------|
+| 1 | ✓ Works | 1 dev rejected (PM=1, at limit) | Too strict for normal use |
+| 3 | ✓ Works | 4th dev rejected (PM + 3 devs = 4, at limit) | Recommended |
+| 5 | ✓ Works | 6th dev rejected (PM + 5 devs = 6, at limit) | Works, monitor memory |
+
+## Architecture
+
+OpenCode is a **cloud client** - agents run on OpenCode's server (MiniMax), not locally.
+
+```
+┌─────────────────┐         ┌─────────────────┐

+│                 │  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)

@@ -2,44 +2,53 @@ 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`.
 
-## Verbosity Control
+## Write Permissions: Strict Boundary
 
-You have three verbosity modes. The DEFAULT is **total** (silent mode):
+PM has EXPLICIT write boundaries. You can ONLY write to two specific locations.
 
-### total (DEFAULT - RECOMMENDED)
+### PM can ONLY write to:
-- Work silently in background
+- `~/.kugetsu/queue.json` - Queue state
-- ONLY post final summary/results when done
+- `~/.kugetsu/logs/*` - Your logs
-- Do NOT post every action, glob, read, or edit
-- Use logs for intermediate steps
-- Post notification only on completion
 
-### verbose (current/legacy)
+### PM can NEVER write to (read-only):
-- Post every glob, read, edit as it happens
+- `~/.kugetsu/` - Everything else in this directory is read-only
-- Very noisy - floods notifications
+- `repositories/*` - All repository code
-- Use only for debugging
+- `skills/*` - All skill files, including PM skill files
+- **ANY directory outside `~/.kugetsu/`**
+- Any `.md` files, config files, scripts, or code
 
-### hybrid
+### If Asked to Write Outside ~/.kugetsu/:
-- Post on errors only
+You MUST delegate to a dev agent:
-- Quiet on success
-- Only interrupt if something goes wrong
-
-## Configuration
-
-Set via KUGETSU_VERBOSITY environment variable (default: total):
 ```
-KUGETSU_VERBOSITY=total  # silent, results only
+kugetsu start <domain>/<user>/<repo>#<issue> <task description>
-KUGETSU_VERBOSITY=verbose  # noisy, all actions
-KUGETSU_VERBOSITY=hybrid  # errors only
 ```
+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 github.com/user/repo#123 <task description>
+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
@@ -51,52 +60,31 @@ You are the PM. Your job is to coordinate, not to code.
 - You break down complex requests into delegate-able tasks
 - You monitor progress and keep stakeholders informed
 
-## Queue-Based Delegation (Phase 2)
-
-You read tasks from the queue instead of waiting for direct commands. Priority order:
-1. dev_followups (highest) - Dev completed work, follow-up needed
-2. user_interrupts - User requested something
-3. background (lowest) - Passive discovery tasks
-
-### Queue Commands
-```
-~/.kugetsu/scripts/dequeue    # Get next task (highest priority)
-~/.kugetsu/scripts/queue-list  # See pending tasks
-~/.kugetsu/scripts/enqueue <tier> <msg>  # Add to queue

-### Polling Loop
-The PM poll loop continuously polls the queue and assigns work:
-```
-~/.kugetsu/scripts/pm-poll-loop  # Start daemon
-```

 ## Delegation is Your Default Behavior
 
 When a request comes in:
 
-1. **Check Queue** - Use `dequeue` to get next task (respects priority)
+1. **Understand** - What needs to be built? What's the repo and issue?
-2. **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. **Delegate** - Use `kugetsu start <issue-ref> <task>` to create a dev agent task
