Your context files are lying to your agents

CLAUDE.md says npm test. Your repo moved to bun weeks ago.
AGENTS.md points to files that no longer exist.
.cursorrules contradicts both.

Your AI agents build on top of that lie every day.

ContextBridge is a CI check that catches semantic drift: dead paths, stale commands, dead conventions and cross-file contradictions. It runs before your agent writes code on them.

What a scan finds

Real classes of drift that no diff-based sync tool catches. The files can be perfectly in sync with each other and still all be wrong about your repo.

$ ctxbridge check · my-saas-app

✗ CLAUDE.md:12  references scripts/build.sh (deleted 24 days ago, commit a3f81c)
✗ AGENTS.md:31  says "run tests with npm test" (package.json has no "test" script; repo uses bun)
⚠ AGENTS.md:47  convention "all API handlers in src/api/" (7 of 12 handlers now live in src/routes/)
✗ conflict     .cursorrules forbids default exports (CLAUDE.md:58 requires them for pages/)
⚠ CLAUDE.md:74  architecture section describes Redis cache (removed from docker-compose 2 sprints ago)

How it works

Connect a repo (or run the CLI locally). ContextBridge parses CLAUDE.md, AGENTS.md, .cursorrules, and your actual codebase.

Every push (or weekly), the scan cross-checks every claim in your context files against repo reality: paths, commands, conventions, architecture statements, cross-file conflicts.

You get a report with exact lines, plus an auto-fix PR for everything that can be corrected mechanically.

Semantic drift detection

Not a diff. The scan understands what your context files claim and verifies it against the code.

Cross-file conflict check

Claude Code, Codex and Cursor each read a different file. ContextBridge makes sure they aren't given contradicting rules.

One canonical context, included

Write context once, compile to CLAUDE.md / AGENTS.md / .cursorrules. Sync is table stakes; verification is the point.

Auto-fix PRs

Dead path? Renamed script? The fix PR is already open. You just review.
