review-bot

AI-powered code review bot for Gitea pull requests.

Overview

review-bot fetches a PR's diff, title, description, and CI status from Gitea, sends it to an LLM via an OpenAI-compatible API, and posts a structured code review back to Gitea.

Usage

review-bot \
  --gitea-url https://gitea.weiker.me \
  --repo owner/name \
  --pr 123 \
  --reviewer-name "sonnet-review-bot" \
  --reviewer-token "$(cat /path/to/token)" \
  --llm-base-url "https://proxy.example.com/v1" \
  --llm-api-key "key" \
  --llm-model "anthropic--claude-4.6-sonnet" \
  --conventions-file "CLAUDE.md"

All flags can also be set via environment variables:

Flag	Env Var
`--gitea-url`	`GITEA_URL`
`--repo`	`GITEA_REPO`
`--pr`	`PR_NUMBER`
`--reviewer-name`	`REVIEWER_NAME`
`--reviewer-token`	`REVIEWER_TOKEN`
`--llm-base-url`	`LLM_BASE_URL`
`--llm-api-key`	`LLM_API_KEY`
`--llm-model`	`LLM_MODEL`
`--conventions-file`	`CONVENTIONS_FILE`

Use --dry-run to print the review to stdout without posting.
