description: Session manager for opencode CLI. Use when managing long-running opencode sessions, resuming interrupted work, or tracking session state across disconnects. Features state tracking (used/idle/left), auto-fill last message on resume, and safe locking via confirmation prompts. description: Issue-driven session manager for opencode CLI. Manages base sessions and per-issue forked sessions with automatic indexing for headless orchestration.

# kugetsu - OpenCode Session Manager # kugetsu - OpenCode Session Manager (Issue-Driven)
Manages opencode CLI sessions with state tracking and safe resume. Manages opencode sessions with a base session + forked session pattern optimized for headless orchestration.

```bash
. skills/kugetsu/scripts/kugetsu ### Session Pattern
- **Base Session**: Created once via TUI, used for forking
- **Forked Sessions**: One per issue, branched from base via `opencode run --fork --session <base>`
### Directory Structure
```
~/.kugetsu/
├── sessions/
│ ├── base.json # Base session metadata
│ └── github.com-shoko-kugetsu-14.json # Forked session per issue
└── index.json # Maps issue refs to session files
``` ```
## Session State ### Index File
```json
{
"base": "ses_abc123",
"issues": {
"github.com/shoko/kugetsu#14": "github.com-shoko-kugetsu-14.json"
}
}
```
| State | Meaning | Resumable? | ### Session File
|-------|---------|------------| ```json
| `used` | Session is active (process running) | Yes (with confirmation) | {
| `idle` | Session ended gracefully | No | "type": "base|forked",
| `left` | Session interrupted/crashed | Yes | "issue_ref": "github.com/shoko/kugetsu#14",
| `invalid` | Session data missing/corrupt | No | "opencode_session_id": "ses_xyz789",
"created_at": "2026-03-29T18:16:10+02:00",
"state": "idle"
}
```
## Session Directory ## Issue Ref Format
Sessions are stored in `~/.kugetsu/sessions/<session_id>/`: All issue references use the format: `instance/user/repo#number`
- `state` - current state (used/idle/left/invalid)
- `message` - last user message (for auto-fill) Examples:
- `pid` - active process PID (when used) - `github.com/shoko/kugetsu#14`
- `gitlab.com/username/project#42`
- `codeberg.org/user/repo#100`
## Commands ## Commands
### kugetsu start `<session_id>` `<message>` ### kugetsu init [--force]
Start a new session:
Initialize base session via TUI:
```bash ```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 once; subsequent runs error unless `--force` is used
- Stores base session ID in `index.json`
### kugetsu start `<issue-ref>` `<message>` [--debug]
Start task for an issue by forking from base session:
```bash ```bash
kugetsu list # Shows only `left` (resumable) kugetsu start github.com/shoko/kugetsu#14 "fix authentication bug"
kugetsu list --all # Shows all states
``` ```
### kugetsu resume `<session_id>` [message] - Forks new session from base
Resume an interrupted session: - Stores mapping in `index.json`
- Uses `opencode run --fork --session <base-session-id> "<message>"`
### kugetsu continue `<issue-ref>` `<message>` [--debug]
Continue work on an existing issue session:
```bash ```bash
kugetsu resume mytask # Auto-fills last message kugetsu continue github.com/shoko/kugetsu#14 "add unit tests"
kugetsu resume mytask "continue" # Uses provided message
``` ```
- If state is `used`: prompts for confirmation (someone else might be using)
- If state is `idle`: errors (not resumable)
- If state is `left`: proceeds with message
### kugetsu stop `<session_id>` - Looks up session file from index
Stop a session gracefully: - Uses `opencode run --continue --session <opencode-session-id> "<message>"`
### kugetsu list
List all tracked sessions:
```bash ```bash
kugetsu stop mytask kugetsu list
``` ```
- Sends SIGTERM to process
- Sets state to `idle`
### kugetsu destroy `<session_id>` [-y] Output:
Delete a session: ```
ISSUE_REF TYPE SESSION_ID CREATED
──────────────────────────────────────────────────────────────────────────────────────────────────
(base) base ses_abc123 N/A
github.com/shoko/kugetsu#14 forked ses_xyz789 2026-03-29T18:16:10+02:00
```
### kugetsu prune [--force]
Remove orphaned sessions (files not in index):
```bash ```bash
kugetsu destroy mytask # Prompts for confirmation (default: N) kugetsu prune # Shows what would be deleted
kugetsu destroy mytask -y # Skips confirmation kugetsu prune --force # Deletes orphaned sessions
``` ```
- Errors if session is `used` (use `stop` first)
- Errors if session not found
### kugetsu destroy --all [-y] - Orphaned = session files in `sessions/` but not in `index.json`
Delete all sessions: - Always keeps `base.json`
- Useful after opencode session cleanup
### kugetsu destroy `<issue-ref>` [-y]
Delete session for specific issue:
```bash ```bash
kugetsu destroy --all # Prompts for confirmation (default: N) kugetsu destroy github.com/shoko/kugetsu#14 # Prompts for confirmation
kugetsu destroy --all -y # Skips confirmation kugetsu destroy github.com/shoko/kugetsu#14 -y # Skips confirmation
```
- Useful for fresh start
### kugetsu help
Show usage help.
## State Transitions
```
start ──────────────► used ──────► idle (stop/SIGTERM)
│
└──────► left (kill/SIGINT/crash)
│
▼
destroy (delete)
``` ```
## Example Workflow ### kugetsu destroy --base [-y]
Delete base session (requires explicit `--base`):
```bash
kugetsu destroy --base -y
```
## Workflow Example
```bash ```bash
# Start a long-running task # First-time setup (requires TTY)
kugetsu start issue42 "implement feature X" kugetsu init
# ... time passes, connection drops ... # Start work on issue
kugetsu start github.com/shoko/kugetsu#14 "implement feature X"
# Check what sessions are resumable # Continue later
kugetsu continue github.com/shoko/kugetsu#14 "add tests"
# Continue again
kugetsu continue github.com/shoko/kugetsu#14 "fix failing test"
# List all sessions
kugetsu list kugetsu list
# Resume with auto-filled message # Clean up orphaned sessions
kugetsu resume issue42 kugetsu prune --force
# Later, when done # Delete session when done
kugetsu stop issue42 kugetsu destroy github.com/shoko/kugetsu#14
# When you want a fresh start
kugetsu destroy --all
``` ```
## 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)
- All subsequent work uses `--fork --session <base>` or `--continue --session <forked>`
## Recovery
If opencode sessions become out of sync:
1. `kugetsu list` shows tracked sessions
2. `kugetsu prune` removes orphaned files
3. For full reset: `kugetsu destroy --base -y && kugetsu init`
## Without kugetsu ## Without kugetsu
If kugetsu is not installed, use opencode directly: If kugetsu is not available, use opencode directly:
```bash ```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.
