code-reviewer

Automated GitLab merge-request reviewer powered by an LLM.

Running the Discord Bot

1. Create a Discord application at https://discord.com/developers/applications
2. Add a bot user; copy the bot token to DISCORD_TOKEN.
3. Copy the application ID to DISCORD_APP_ID.
4. Invite the bot to your server with the applications.commands and bot scopes.
5. Fill in config.yaml (see config.example.yaml) and the env vars above plus GITLAB_TOKEN and your LLM API key.
6. Run:

   go build ./cmd/bot && ./bot --config config.yaml
   

7. In any channel the bot can see, run /review url:<gitlab-mr-url>.

The bot supports four providers via llm.provider in config.yaml:

• anthropic (default): set ANTHROPIC_API_KEY. Uses prompt caching.
• openai: set OPENAI_API_KEY. Uses Chat Completions with JSON-object response format.
• ollama: no API key needed; defaults to http://localhost:11434. Override with llm.base_url.
• openrouter: set OPENROUTER_API_KEY as llm.api_key. Defaults to https://openrouter.ai/api. Use OpenRouter slugs like openai/gpt-4o or anthropic/claude-3.5-sonnet for llm.model. Optionally set llm.referer and llm.title for app ranking. JSON mode is not sent (works across all OR models); ParseFindings tolerates prose-wrapped JSON.

Smoke test

cp config.example.yaml config.yaml
# fill GITLAB_TOKEN, ANTHROPIC_API_KEY in env
./review-cli --config config.yaml https://gl.your-corp.com/team/proj/-/merge_requests/N
