Build a Headless Claude Code Review Bot for CI
Automate code review with Claude in CI: run it headlessly against a diff, return a structured pass/fail verdict the pipeline can parse, run it as an independent review session rather than self-review, and gate the build on the result. Submit a single script for instant, rubric-based feedback.

The scenario
Reviews on your team are inconsistent and slow, and an earlier attempt at automating them piped Claude's prose output into grep, so the pipeline could never reliably tell pass from fail. Worse, the same session that wrote a change was asked to review it, so it rubber-stamped its own work.
You are going to build a real review bot: it runs Claude headlessly against the diff, returns a structured verdict the CI can act on, reviews from a fresh independent context, and blocks the build when it finds a real problem.
Your role
You are a Claude solutions architect automating code review. Your deliverable is one script that runs Claude headlessly on a change, produces a structured verdict, reviews independently, and gates the build.

What you'll build in this Claude review bot task
This is a build-and-submit task, not a guided lab. You build a real code-review bot on Claude: it runs headlessly against a diff in CI, returns a structured pass/fail verdict the pipeline can act on, reviews from an independent context, and blocks the build when it finds a genuine problem. The deliverable is one script you could wire into a pipeline.
The patterns here are the ones that make AI review trustworthy instead of theatrical. You stop scraping prose and demand a structured verdict, you feed the actual change rather than a summary, you review from a fresh session so the bot is not grading its own homework, and you gate the build on severity so the review has teeth.
Grading is rubric-based and explainable. Your submission is scored against weighted criteria (headless invocation, the structured verdict, independent review, build gating, real-change input, and team standards) with per-criterion feedback quoted from your code. The pass threshold is 65 percent and you can resubmit. These are the Claude Code workflow-automation skills the Claude Certified Architect exam tests.
