Agent Code Review

PR review queue with agent-code-review

agent-code-review is a CLI binary on $PATH. Default output is NDJSON: one JSON record per line on stdout. Errors go to stderr as one JSON line {"error": "...", "fixable_by": "agent"|"human"|"retry", "hint": "..."} with a non-zero exit.

It maintains a DuckDB-backed queue of candidate PRs and reviews them with a pluggable engine (Codex or Claude Code; default: Codex). Configuration lives at ~/.config/agent-code-review/config.json: repos, the author groups, age thresholds, schedule, and the review prompt + rules.

Inspect the queue

agent-code-review queue ls                   # all pending candidates, NDJSON
agent-code-review queue ls --repo owner/name

The queue holds only pending work, FIFO by first discovery; a row with claimed_at set is being reviewed right now, and a row with eligible_at in the future is on hold (hold_reason: settling = the PR was pushed or edited within candidates.quiet_period; cooldown = we reviewed it within candidates.rereview_cooldown); it is not dispatched until then. Completed outcomes live in history (see the dashboard's History page).

Manage candidates

agent-code-review queue add     owner/name 1234   # add a PR (fetches live metadata; rejects closed/merged; no holds)
agent-code-review queue promote owner/name 1234   # review NOW: top of queue, clears any hold, treated as manual
agent-code-review queue skip    owner/name 1234   # record SKIPPED and drop (re-eligible on new commits)
agent-code-review queue rm      owner/name 1234   # remove, recording nothing
agent-code-review queue log     owner/name 1234 -f # stream the review agent's log (live or postmortem)

Manage the author roster (which group each author is in, per repo, in DuckDB)

agent-code-review authors set owner/name alice core --name "Alice" --slack-id U01
agent-code-review authors set '*' bob outsider     # that group on every repo
agent-code-review authors ls --repo owner/name     # rows + the policy each resolves to
agent-code-review authors groups                   # the cohorts and what each grants
agent-code-review authors who alice --repo owner/name
agent-code-review authors rm owner/name alice

We are the reviewer. An author belongs to ONE group per repo, and the group (defined in config under authors.groups) is a complete review policy: the review level (ignore = never discovered, though a manual queue add still reviews; comment = reviewed but never approved; approve = approvable), plus the engine, model, effort, and an extra prompt fragment. authors.overrides narrows any of that per handle.

Resolution: the roster row for this repo, else the row for *, else authors.unlisted[repo], else authors.unlisted["*"]; then every matching override patches it field by field. authors who names the deciding layer per field, which is how to answer "why did that PR get approved / ignored". Only this PR's own resolved policy reaches the engine, never the roster.

Run reviews

agent-code-review run                                # drain the queue, then exit
agent-code-review serve --http :8330                 # daemon + dashboard
agent-code-review serve --http :8330 --tailscale serve   # + expose on tailnet

Configuration

agent-code-review config path      # where the config lives
agent-code-review config show      # current config (NDJSON)

See config.example.json in the repo for the full shape. The CLI never hardcodes repos or GitHub handles; everything is config.

Notes

• Requires gh (authenticated), the duckdb CLI, and the configured review engine (codex by default, or claude) on $PATH, already authenticated.
• Candidate rules: NEW (never reviewed, ≤14d) and REFRESHED (head SHA changed since our last review, ≤21d). Processed FIFO by first discovery, up to 4 in parallel. Already-approved PRs are skipped, and any recorded outcome at the current head SHA suppresses re-enqueueing.
• Discovered candidates wait out eligibility holds (quiet period default 15m, re-review cooldown default 90m, 0s disables) so the agent doesn't review mid-push or instantly re-review; queue promote or a manual queue add bypasses them. Manual rows also skip the pre-review candidacy recheck.
• Most config edits reload live within ~30s (cadence, parallelism, usage floors, repos, prompts); only the loop switches and dashboard/Tailscale settings need a daemon restart. A candidate is HELD when the engine that would review it drops below schedule.usage_floor.* percent remaining. The floor is per engine, since a group can name its own: one engine being out of headroom does not hold candidates bound for the other. A held candidate is never claimed or recorded, so it runs when the window refills.
• The agent does the actual review and GitHub actions, then reports back what it did (APPROVED|COMMENTED|REQUESTED_CHANGES|SKIPPED). The assembled prompt carries a built-in approval directive that defaults to comment-only; approval needs an approve-level group AND a non-self-authored PR (the self-review veto sits above the group cascade and no group can lift it). Post-outcome behaviour comes from review.on_approve/on_comment/on_reject in config.
• Manage watched repos with repos ls|add|rm, prompts with prompts show|set|unset|preview, and scalar dials with config list|get|set|unset (all persisted to config.json).
• Every command group has a usage subcommand with full docs and examples.
