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 labeled formula, action, prediction/dismissed, or prediction/unreviewed (replaced prediction/backlog — that label no longer exists)
  • dev/dev-agent.sh — Orchestrator: claims issue, creates worktree + tmux session with interactive claude, monitors phase file, injects CI results and review feedback, merges on approval
  • dev/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. Sources lib/mirrors.sh and calls mirror_push() after every successful merge. Matrix escalation notifications include MATRIX_MENTION_USER HTML mention when set.
  • 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 account
  • FORGE_REPO, FORGE_API, FORGE_URL — Target repository (FORGE_URL used to auto-detect git remote)
  • PROJECT_NAME, PROJECT_REPO_ROOT — Local checkout path
  • PRIMARY_BRANCH — Branch to merge into (e.g. main, master)
  • WOODPECKER_REPO_ID — CI pipeline lookups
  • CLAUDE_TIMEOUT — Max seconds for a Claude session (default 7200)
  • MATRIX_TOKEN, MATRIX_ROOM_ID, MATRIX_HOMESERVER — Notifications (optional)

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).

Lifecycle: dev-poll.sh (check_active dev) → dev-agent.sh → create Matrix thread + export MATRIX_THREAD_ID → 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.
