Pi doesn't log tool calls to stderr in print mode. Instead, we save
the session (.jsonl) and parse it to extract every tool_use entry
showing which files were read, grep patterns used, etc.
When debug: true, the review comment includes a collapsible section
showing which files the agent read, grep patterns used, etc.
Also prints agent log on failure for easier troubleshooting.
Reusable Gitea/GitHub action that runs Pi coding agent for
AI-powered code reviews on pull requests.
- Docker image based on node:24-slim (112 packages)
- Supports built-in providers (zai, anthropic, openai, deepseek, openrouter)
and custom OpenAI-compatible endpoints
- Generates git diff (excludes lockfiles/generated code by default)
- Posts review as idempotent PR comment (updates existing on re-run)
- Read-only tools only: agent investigates but never modifies code
- 80KB default diff truncation to stay within LLM context windows
- No curl/python3 dependency — uses Node.js for HTTP and JSON
