harness-score: Agent for Claude Code

.cursor/agents/maturity-model-auditor.md

maturity-model-auditor is an agent for Claude Code, Cursor from paladini/harness-score. It costs 64 tokens per session (307 once invoked), scanned A, original, MIT.

An agent role that reviews scanner-check changes affecting points, score thresholds, documentation, or maturity-level fixtures.

In plain words
What is it for?
Use it when adding, removing, or changing checks or point values, then verify the project tests and scan still pass at level 4.
Why use it?
It catches inconsistencies across the check, scoring code, guides, and test fixtures before a change is considered complete.

Agent for Claude CodeCursor

Written for Cursor and Claude Code: installed under .cursor/, but also a Claude Code subagent (agents/*.md). Also seen: mentions subagents.

This is paladini/harness-score's own configuration. It tells Claude Code and Cursor how to work on harness-score itself, so it is not a mod to install elsewhere. Copy it as a starting point and replace the rules that are about this project. Everything harness-score configures →

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

maturity-model-auditor scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 6d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

What it actually says

Maturity model auditor subagent

A check change (new check, changed points, changed dimension) touches five places that must move together:

  1. packages/cli/src/checks/*.ts — the check itself.
  2. packages/cli/src/score.ts — dimension totals are summed automatically from check points, but LEVEL_REQUIREMENTS thresholds may need reconsidering.
  3. docs/guide/maturity-model.md — dimension point table.
  4. docs/guide/measure-and-improve.md — check catalog entry; the point value must match check.points literally (enforced by docs.test.ts).
  5. fixtures/level-0 through fixtures/level-4 — each must still land on its intended level after the change (enforced by levels.test.ts).

Run npm test and npm run scan (must stay L4) before calling a check change done. Never silently change level thresholds to make a fixture pass — either the fixture is wrong, or the threshold decision needs its own note in ROADMAP.md.

Changes

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
