harness-score is a plugin for Cursor from paladini/harness-score. Its token cost is not measured, scanned A, original, MIT.

Deterministic harness-maturity audit for your repository: measures AGENTS.md, rules, skills, hooks, sensors, CI, and hygiene against a 5-level maturity model — without any LLM calls — and teaches the agent how to fix every gap.

Security

Grade A, and why

harness-score 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 yesterday.

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 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.
