What’s Changed

Added

  • operational_coverage dimension for AGENTS.md (#83). Measures whether an AGENTS.md actually equips a coding agent to operate the repo: real setup/build/test commands (command-family classification, doc-wide, headings never gate) plus code-style / gotchas / PR directive sections with concrete code tokens. Surfaced in the CLI dimension table, the GitHub Action’s PR comment, and accepted by the leaderboard submit API.

Changed

  • BREAKING (scores): the AGENTS.md headline profile is now structure 0.40 / operational_coverage 0.40 / efficiency 0.20 (was 0.5/0.5). efficiency was a validated gameable proxy — a junk-fence-stuffed doc scored 92.5/A while the same real commands written inline scored 70.0/C. All AGENTS.md scores re-baseline (30-file corpus: mean 61.06, no file reaches S). SKILL.md / CLAUDE.md / .cursorrules / system-prompt scoring is byte-identical to 8.3.0.

Security

  • Fixed a ReDoS in the operational_coverage heading regex (quadratic on whitespace-only heading lines) before it ever shipped — found by a 75-agent adversarial review pass, together with a directive-gate gaming hole, a fence-state desync, and 12 command-recall bugs. Full record: docs/specs/agents-md-operational-coverage.md §11.
