A large slice of that harness lives in your repository — and repo-readiness should be measured, not vibed.

When agents fail, the repo is often the reason. Why agent-readiness belongs in CI.

Here's how Charter turns a repo from an honest baseline into a wall every pull request has to clear — and why the hard caps matter more than the formula.

Charter grades any repository 0–100 on how safely an agent can operate in it — offline, deterministic, and with a concrete fix for every gap. Thu, 18 Jun 2026 00:00:00 GMT launch ai-agents
