# 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. It performs a direct-merge scan first (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 on another issue. **Key files**: - `dev/dev-poll.sh` — Cron scheduler: finds next ready issue, handles merge/rebase of approved PRs, tracks CI fix attempts - `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 - `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` — Target repository - `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) **Lifecycle**: dev-poll.sh → dev-agent.sh → create Matrix thread + export `MATRIX_THREAD_ID` (streams Claude output to thread via Stop hook) → tmux `dev-{project}-{issue}` → phase file drives CI/review loop → merge → close issue.
