Start an agent session correctly in KanbAgent. Activates when an agent needs to begin work, when user says "start a session", "launch agent X", "begin session", or when an agent role is invoked and no active session exists. Ensures correct startup sequence: dbstart → read tasks → begin work.
Write agent_logs entries correctly in KanbAgent. Activates when an agent needs to log an action, when completing a task, starting a session, or when agent_logs entries are missing. Triggers on "log this", "insert agent_log", "add a log", or any task_started/task_done/session_end event.
Write an Architecture Decision Record (ADR) for KanbAgent following the project's existing format. Activates when a structural decision needs to be documented, when agent arch completes a design decision, or when user says "ADR", "architecture decision", "document this choice".
Create a new typed IPC handler in KanbAgent following the full stack pattern. Activates when user or agent needs to add a new IPC channel, expose a new API to the renderer, or wire a new feature across main/preload/renderer. Triggers on "add IPC", "new handler", "expose to renderer", "new IPC channel", "create a handler".
Create a versioned SQLite migration for KanbAgent. Activates when the DB schema needs to change, when user says "add a column", "create a table", "migration", "alter schema", "add a column", "modify the schema". Follows the existing migration pattern with idempotency and better-sqlite3 compatibility.
Execute a release in KanbAgent following the full devops + review protocol. Activates when agent devops receives a release ticket, when user says "release", "publish version", "bump version", "npm run release". Covers prerequisites, version bump, CI wait, GitHub Release publication.

Diagnose and manually clean zombie sessions in project.db.
node scripts/dbq.js "SELECT s.id, a.name, s.started_at, s.summary FROM sessions s JOIN agents a ON a.id = s.agent_id WHERE s.status = 'started' ORDER BY s.started_at DESC"
node scripts/dbq.js "SELECT s.id, a.name, s.started_at FROM sessions s JOIN agents a ON a.id = s.agent_id WHERE s.status = 'started' AND s.ended_at IS NULL AND s.started_at < datetime('now', '-60 minutes')"
node scripts/dbw.js <<SQL UPDATE sessions SET status = 'completed', ended_at = datetime('now'), summary = 'Manually closed: zombie session' WHERE id = ; SQL
node scripts/dbw.js <<SQL UPDATE sessions SET status = 'completed', ended_at = datetime('now'), summary = 'Force-closed: zombie >60min' WHERE status = 'started' AND started_at < datetime('now', '-60 minutes'); SQL
node scripts/dbq.js "SELECT COUNT(*) as active_sessions FROM sessions WHERE status = 'started'"
active_sessions should return 0 if cleanup was total.
dbstart exit code 2? ├─ Check active sessions → some are >60min? → nuclear option ├─ All sessions recent → Real parallel limit → close one voluntarily └─ max_sessions = -1 in DB? → No limit, shouldn't happen
After any forced kill of a Claude Code session:
