AgentConfigScore

AgentConfigScore

Codecov for AI coding-agent instructions.

Stop pull requests from quietly making AGENTS.md, CLAUDE.md, Cursor, Copilot and Gemini instructions worse.

AgentConfigScore is a deterministic regression gate for coding-agent configuration. It compares a change with its baseline and answers one CI-friendly question:

**Did this change make our agent instructions worse?**

It is regression-first rather than perfection-first: an existing repository can start at 72/100 and adopt the gate immediately. A pull request that stays at 72 can pass; one that drops to 65 can fail.

What usually goes wrong	What the gate does
A pull request weakens its own quality threshold	Uses the baseline branch's policy to judge the change
A new instruction contradicts or duplicates existing guidance	Reports deterministic, line-addressable findings
An exception becomes a permanent silent ignore	Requires a reason and expiry, then preserves an audit trail
A scanner update becomes noisy on real projects	Replays a pinned, manually reviewed real-repository benchmark
