README

pr-review-agent

A LangGraph.js agent that reviews a pull request: it summarizes the change, analyzes each file, checks whether the tests cover it, flags risks, and writes a structured review. **Nothing is posted until a human approves it.** It comes with a CLI and a Next.js UI that streams the agent's steps live.

It's part two of a three-part series on production AI engineering for code review:

Repo	Role
`mcp-repo-tools`	MCP server: the agent's only, read-only view of the repository
pr-review-agent (this)	The agent: orchestration, model calls, human approval, publishing
`gameable-tests-bench`	Next: tasks with deliberately weak tests, and a grader that catches agents gaming them
