openhands f37546c6fc chore: gardener housekeeping 2026-03-22 
- Update all AGENTS.md watermarks to current HEAD (251d160)
- dev/AGENTS.md: document dev-poll's early direct-merge scan (before lock
  check) — approved PRs now merge without waiting for active dev sessions;
  chore/gardener PRs merge without issue numbers in branch name
- planner/AGENTS.md: document dispatch-idle-formulas phase (step 4); note
  that planner reads both factory and project-specific formulas; clarify
  that all planner artifacts use $PROJECT_REPO_ROOT, not $FACTORY_ROOT

Supervisor Agent

Role: Health monitoring and auto-remediation, executed as a formula-driven Claude agent. Collects system and project metrics via a bash pre-flight script, then runs an interactive Claude session (sonnet) that assesses health, auto-fixes issues, escalates via Matrix, and writes a daily journal.

Trigger: supervisor-run.sh runs every 20 min via cron. It creates a tmux session with claude --model sonnet, injects formulas/run-supervisor.toml with pre-collected metrics as context, monitors the phase file, and cleans up on completion or timeout (20 min max session). No action issues — the supervisor runs directly from cron like the planner and predictor.

Key files:

  • supervisor/supervisor-run.sh — Cron wrapper + orchestrator: lock, memory guard, runs preflight.sh, sources disinto project config, creates tmux session, injects formula prompt with metrics, monitors phase file, handles crash recovery via run_formula_and_monitor
  • supervisor/preflight.sh — Data collection: system resources (RAM, disk, swap, load), Docker status, active tmux sessions + phase files, lock files, agent log tails, CI pipeline status, open PRs, issue counts, stale worktrees, blocked issues, Matrix escalation replies
  • formulas/run-supervisor.toml — Execution spec: five steps (preflight review, health-assessment, decide-actions, report, journal) with needs dependencies. Claude evaluates all metrics and takes actions in a single interactive session
  • supervisor/journal/*.md — Daily health logs from each supervisor run (local, committed periodically)
  • supervisor/PROMPT.md — Best-practices reference for remediation actions
  • supervisor/best-practices/*.md — Domain-specific remediation guides (memory, disk, CI, git, dev-agent, review-agent, codeberg)
  • supervisor/supervisor-poll.sh — Legacy bash orchestrator (superseded by supervisor-run.sh + formula)

Alert priorities: P0 (memory crisis), P1 (disk), P2 (factory stopped/stalled), P3 (degraded PRs, circular deps, stale deps), P4 (housekeeping).

Matrix integration: The supervisor has its own Matrix thread. Posts health summaries when there are changes, escalates P0-P2 issues, and processes replies from humans ("ignore disk warning", "kill that agent", "what's stuck?"). The Matrix listener routes thread replies to /tmp/supervisor-escalation-reply, which supervisor-run.sh consumes atomically on each run.

Environment variables consumed:

  • CODEBERG_TOKEN, CODEBERG_REPO, CODEBERG_API, PROJECT_NAME, PROJECT_REPO_ROOT
  • PRIMARY_BRANCH, CLAUDE_MODEL (set to sonnet by supervisor-run.sh)
  • WOODPECKER_TOKEN, WOODPECKER_SERVER, WOODPECKER_DB_PASSWORD, WOODPECKER_DB_USER, WOODPECKER_DB_HOST, WOODPECKER_DB_NAME — CI database queries
  • MATRIX_TOKEN, MATRIX_ROOM_ID, MATRIX_HOMESERVER — Matrix notifications + human input

Lifecycle: supervisor-run.sh (cron */20) → lock + memory guard → run preflight.sh (collect metrics) → consume escalation replies → load formula + context → create tmux session → Claude assesses health, auto-fixes, posts Matrix summary, writes journal → PHASE:done.
