SOURCEBOOK FOR TEAMS

Catch incomplete PRs
before they ship.

Your AI agent submitted a PR that looks done. The handler changed but the test didn't. The config updated but the migration wasn't created. sourcebook catches what's missing.

THE_PROBLEM

AI agents don't just hallucinate. They stop too early. They find the right file, make a clean edit, and move on — leaving test files, sibling components, and co-dependent configs unchanged. The PR passes CI. The bug shows up days later.

100%

Completeness gate accuracy on 30 real diffs. If something's missing, it catches it.

0%

False positive rate on clean diffs. Doesn't cry wolf on complete changes.

$0.01

Per AI-powered analysis. Structural checks are instant and free.

HOW_IT_WORKS

01

CLI — check any diff locally

sourcebook check reads your staged changes and checks them against the repo's git co-change history, test file mappings, and import graph. No LLM. Under a second.

02

Hooks — catch it before the commit

sourcebook init wires up Claude Code hooks. Agent edits a file, sourcebook checks the diff, agent sees what's missing — all before the commit lands.

03

GitHub App — catch it on the PR

sourcebook reviews every PR for structural completeness. Comments with specific files that likely need to change. No more incomplete merges slipping through review.
