Audits and restructures a project's AI agent harness (CLAUDE.md, AGENTS.md, GEMINI.md, rules, skills, hooks, docs and Obsidian vault notes) so an agent starts each session with a short map and finds the rest on demand, then installs the guardrails that keep it that way. Expect the win in speed, consistency and blast radius rather than in tokens. Run manually with /harness-audit diagnose | apply | verify | check. Supports Claude Code, Codex, Cursor and Antigravity CLI, with or without Obsidian.

Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.

What the file says

# Harness audit

Goal: an agent starts each session with a small, stable map and finds everything else on demand, and the project stays that way after you leave.

Evidence to keep in mind (details in `references/principles.md`): more always-loaded instructions degrade adherence and cost; auto-generated or redundant instruction files can lower task success; so this skill **removes and relocates** more than it writes, and **measures** before and after.

`SKILL_DIR` below means the folder containing this file. Scripts need only Python and git.

## Commands

| Command | Writes | Purpose |
|---|---|---|
| `diagnose` (default) | `.harness/reports/` only | Setup interview, inventory, baseline, scorecard, change plan |
| `apply` | project files, on a git branch, after approval | Execute the approved plan, install maintenance layer |
| `verify` | `.harness/reports/` | Re-measure, lock budgets, write the final report |
| `check` | nothing | Fast maintenance lint for periodic use |

If the user gives no argument, run `diagnose`. Never run `apply` without an approved plan from `diagnose` in this project.

How to install

The exact contents, by fingerprint
mdr add fmslutions/harness-audit/harness-audit@sha256:8980c288592be2b6

The line at the top of this page pins the label v1.5.2, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
