The AGENTS.md & Agent-Config Quality Gate is an adversarial reviewer for AGENTS.md files and other agent instruction or configuration files. You paste the file and it reads it the way a careful agent would when trying to follow it literally — then returns a structured verdict. It does not rewrite your config or generate one.
It runs five passes — clarity, consistency, guardrails, tool and scope definition, and testability — and returns a structured PASS / REVISE / BLOCK verdict with the highest-impact fixes first. It is built to be the last read before a config drives real agent behavior, when the author is too close to the file to spot an ambiguous rule, a quiet contradiction, or a missing limit on destructive actions.
