# gitea-review-bot: AGENTS.md

gitea-review-bot is a **thin Matrix bot that runs an AI PR-review-and-merge workflow for your Gitea
repos**, one review room per repo. It is a *separate* bot from `matrix-bridge` (which turns Matrix
messages into interactive Claude Code sessions): this one's single responsibility is **reviewing
pull requests** — so every room it's in is a review room and there is no manual "ignore this room"
wiring. Invite it to a room, it auto-joins and maps the room to a repo by name, then for that repo
it polls Gitea PRs, posts a headless `claude -p` review as a Matrix thread, and lets you merge/reject
from the thread.

> **Inbox check:** At session start, if `~/Projects/standards/INBOX.md` exists, scan it for items
> tagged `(gitea-review-bot)` and surface them before proposing next steps; triage with `/triage`.

## Stack

Python + **matrix-nio**, one thin Docker container on the Spark (same shape as `matrix-bridge` and
the `ten31-database` intake bot). No framework (Maubot rejected — see Decisions). The heavy work —
the `claude -p` review and any deploy — runs **on the Mac over SSH**, reusing matrix-bridge's proven
wrappers (`scripts/ask-claude.sh` for the review, `scripts/deploy-site.sh` for publish). State is
flat JSON in a writable `state/` mount.

## Placement

| Dimension | Call |
|---|---|
| Host | **Spark**, plain Docker container (NOT Start9/s9pk) |
| Runtime | Long-running service: matrix-nio sync + a Gitea poll loop over mapped repos |
| Model routing | `claude -p` on the Mac via the Spark→Mac SSH seam (subscription); the review session spawns subagents (reviewer / adjudicator / security-auditor) |
| Data layer | Flat JSON in `state/` (room→repo map + enabled agents + reviewed-PR heads + thread roots) |
| Interface | Matrix — one review room per repo (+ phone) |
| Repo home | Local + Gitea (`ssh://git@immense-voyage.local:59916/grant/gitea-review-bot.git`) |
| Sensitivity | Sends PR diffs to `claude -p` (subscription). Fine for code review; flag the boundary before pointing it at a sensitive repo. |

## Commands

- **Run (container, on the Spark):** from `~/gitea-review-bot`, `docker compose up -d --build`
  (host networking, `restart: unless-stopped`; read-only mounts of `.env`/`config.toml`/SSH key,
  read-write `state/`). Logs: `docker compose logs -f`.
- **Deploy:** the Spark's `~/gitea-review-bot` is a Gitea clone tracking `master`; deploy =
  `git fetch && git reset --hard origin/master && docker compose up -d --build` (or a Spark Control
  Update tile, once added — captured in the inbox). `config.toml` is gitignored — refresh it on the
  Spark separately (scp) like matrix-bridge.
- **Onboard a repo:** create a Matrix room named like the repo, invite this bot → it auto-joins,
  maps the room to `<owner>/<roomname>` (+ `~/Projects/<roomname>` on the Mac), and posts an
  onboarding message. Pick review agents in-chat: `agents +reviewer +security -adjudicator`.
- **In a review room:** `merge` / `reject` (inside a PR's thread, or `merge <n>` by number), `yes`/`no`
  to confirm a merge, `agents …` to toggle the subagent panel.

## Layout

- `src/bot.py` — the bot: matrix-nio sync; auto-join + in-room auto-map (room→repo by name); a Gitea
  poll loop per mapped repo; threaded `claude -p` review (subagent panel); merge/reject/deploy
  in-thread; whole-thread redaction on resolve (server-enumerated, restart-proof).
- `config.example.toml` — homeserver, `[mac]` (ssh alias + the reused matrix-bridge wrapper paths),
  `[gitea]` (api_base/owner/verify_tls), `[defaults]`, optional `[repo.<name>]` deploy overrides.
- `.env.example` — `MATRIX_*` + `GITEA_TOKEN` (real `.env` gitignored).
- `Dockerfile` · `docker-compose.yml` · `docker-entrypoint.sh` — the Spark container (generic image;
  secrets/config via read-only mounts; entrypoint writes `~/.ssh/config` for the Mac alias).
- `state/` — gitignored runtime JSON (`rooms.json`: room map + agents + heads + thread roots).

## Decisions

- **Separate bot from matrix-bridge** (single responsibility = PR review). Beat: extending
  matrix-bridge with review-room special-casing. Reopens if the two bots' logic heavily overlaps.
- **Thin matrix-nio container, NOT Maubot.** Reevaluated 2026-06-28: Maubot helps with the Matrix
  plumbing we've already solved, not the SSH/`claude -p`/poll logic that's the actual weight, and it
  reintroduces a web-UI/management layer (Spark Control is the dashboard). Reopens at ~6+ bots or a
  non-developer web-management need; the lighter step first is a shared "bot kit" library.
- **Subagent panel (Option B):** the lead `claude -p` session spawns subagents and presents each
  output + its own overall recommendation. Beat: bot-orchestrated separate `claude -p` runs (more
  deterministic but 3× the sessions + more bot code). Reopens if headless subagent spawning is flaky.
- **Panel composition is per-room, set in chat** (onboarding message + `agents +/-`), not config.
- **Reuse matrix-bridge's Mac wrappers + Spark→Mac SSH key** (don't duplicate the seam).
- **Auto-map by name:** room `<x>` → Gitea `<owner>/<x>` + `~/Projects/<x>`; mapping persists to
  `state/` (mirrors matrix-bridge D14). One room per repo.

## Sovereignty

Reviews send PR diffs to `claude -p` (the subscription), not a frontier API on payload data; that's
acceptable for code review of these repos. Before pointing the bot at a repo with sensitive content,
revisit this — local inference via Spark Control would be the path.

## Current state

**Scaffolded + initial bot built 2026-06-28.** First milestone: invite the bot to a room named
`<repo>` → it auto-joins, maps to `grant/<repo>`, and within ~60s of a new PR posts a threaded
`claude -p` review; `merge` + `yes` in that thread merges it on Gitea and redacts the thread. Core
flow ported from matrix-bridge (D15–D19), generalized to multi-repo + the subagent panel.
**Not yet run** — needs the bot's `.env` (Matrix creds + `GITEA_TOKEN`) + `config.toml` on the
Spark, then `docker compose up -d --build`; then onboard the first repo and validate the panel +
in-chat agent toggles. A Spark Control tile is captured in the cross-project inbox.
