Dev Agent
Role: Implement issues autonomously — write code, push branches, address CI failures and review feedback.
Trigger: dev-poll.sh runs every 10 min via cron. Sources lib/guard.sh and
calls check_active dev first — skips if $FACTORY_ROOT/state/.dev-active is
absent. Then performs a direct-merge scan (approved + CI green PRs — including
chore/gardener PRs without issue numbers), then checks the agent lock and scans
for ready issues using a two-tier priority queue: (1) priority+backlog issues
first (FIFO within tier), then (2) plain backlog issues (FIFO). Orphaned
in-progress issues are also picked up. The direct-merge scan runs before the lock
check so approved PRs get merged even while a dev-agent session is active.
Key files:
dev/dev-poll.sh— Cron scheduler: finds next ready issue, handles merge/rebase of approved PRs, tracks CI fix attempts. Formula guard skips issues labeledformula,action,prediction/dismissed, orprediction/unreviewed(replacedprediction/backlog— that label no longer exists)dev/dev-agent.sh— Orchestrator: claims issue, creates worktree + tmux session with interactiveclaude, monitors phase file, injects CI results and review feedback, merges on approvaldev/phase-handler.sh— Phase callback functions:post_refusal_comment(),_on_phase_change(),build_phase_protocol_prompt().do_merge()detects already-merged PRs on HTTP 405 (race with dev-poll's pre-lock scan) and returns success instead of escalating. Sourceslib/mirrors.shand callsmirror_push()after every successful merge.dev/phase-test.sh— Integration test for the phase protocol
Environment variables consumed (via lib/env.sh + project TOML):
FORGE_TOKEN— Dev-agent token (push, PR creation, merge) — use the dedicated bot accountFORGE_REPO,FORGE_API,FORGE_URL— Target repository (FORGE_URL used to auto-detect git remote)PROJECT_NAME,PROJECT_REPO_ROOT— Local checkout pathPRIMARY_BRANCH— Branch to merge into (e.g.main,master)WOODPECKER_REPO_ID— CI pipeline lookupsCLAUDE_TIMEOUT— Max seconds for a Claude session (default 7200)
FORGE_REMOTE: dev-agent.sh auto-detects which git remote corresponds to FORGE_URL by matching the remote's push URL hostname. This is exported as FORGE_REMOTE and used for all git push/pull/worktree operations. Defaults to origin if no match found. This ensures correct behaviour when the forge is local Forgejo (remote typically named forgejo) rather than Codeberg (origin).
Session lock: fd-based flock — released during idle phases (awaiting_review, awaiting_ci) so other agents can proceed; re-acquired before injecting the next prompt. This prevents the lock from blocking the whole factory while the dev session waits.
Crash recovery: on PHASE:crashed or non-zero exit, the worktree is preserved (not destroyed) for debugging. Location logged. Supervisor housekeeping removes stale crashed worktrees older than 24h.
Lifecycle: dev-poll.sh (check_active dev) → dev-agent.sh → tmux dev-{project}-{issue} → phase file
drives CI/review loop → merge + mirror_push() → close issue. On respawn after
PHASE:escalate, the stale phase file is cleared first so the session starts
clean; the reinject prompt tells Claude not to re-escalate for the same reason.
On respawn for any active PR, the prompt explicitly tells Claude the PR already
exists and not to create a new one via API.
