What is harness-audit?

A repository audit command that checks a project’s agent-related files and rules, then returns a repeatable scorecard.

Use it to audit the whole project or only its hooks, skills, commands, or agents, with results shown as text or JSON.

It gives you a consistent way to find gaps in tools, checks, stored instructions, evaluations, security rules, and spending controls without judging each area manually.

harness-audit — Command for Claude Code by hmj1026

Install

Getting it into your agent

It runs from inside its repository, so the clone comes first — what it calls does not travel with the file alone.

Clone the repo

git clone --depth 1 https://github.com/hmj1026/dhpk

agentmods

npx agentmods add commands/hmj1026/dhpk/harness-audit

Made for: Claude Code.

Or install dhpk, the plugin that ships this one along with the rest of its 65 skills, 31 commands, 37 agents, 4 hooks.

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.

Model	Per session	Once invoked
Fable 5.1	$0.00013	$0.00683
Opus 5	$0.00006	$0.00342
Sonnet 5	$0.00003	$0.00137
Haiku 4.5	$0.00001	$0.00068

Security

Grade A, and why

harness-audit 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 7d 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.

Harness Audit Command

Run a deterministic repository harness audit and return a prioritized scorecard.

See also: /dhpk:harness-govern chains this audit into an end-to-end measure -> conform -> fix -> verify loop.

Usage

/dhpk:harness-audit [scope] [--format text|json] [--root path]

scope (optional): repo (default), hooks, skills, commands, agents
--format: output style (text default, json for automation)
--root: audit a specific path instead of the current working directory

Deterministic Engine

Always run:

node scripts/harness-audit.js <scope> --format <text|json> [--root <path>]

This script is the source of truth for scoring and checks. Do not invent additional dimensions or ad-hoc points.

Rubric version: 2026-03-30.

The script computes 7 fixed categories (0-10 normalized each):

Tool Coverage
Context Efficiency
Quality Gates
Memory Persistence
Eval Coverage
Security Guardrails
Cost Efficiency

Scores are derived from explicit file/rule checks and are reproducible for the same commit. The script audits the current working directory by default and auto-detects whether the target is the dhpk repo itself or a consumer project using dhpk.

Output Contract

Return:

overall_score out of max_score (70 for repo; smaller for scoped audits)
Category scores and concrete findings
Failed checks with exact file paths
Top 3 actions from the deterministic output (top_actions)
Suggested dhpk skills to apply next

Checklist

Use script output directly; do not rescore manually.
If --format json is requested, return the script JSON unchanged.
If text is requested, summarize failing checks and top actions.
Include exact file paths from checks[] and top_actions[].

Example Result

Harness Audit (repo): 66/70
- Tool Coverage: 10/10 (10/10 pts)
- Context Efficiency: 9/10 (9/10 pts)
- Quality Gates: 10/10 (10/10 pts)

Top 3 Actions:
1) [Security Guardrails] Add prompt/tool preflight security guards in hooks/hooks.json. (hooks/hooks.json)
2) [Tool Coverage] Sync commands/harness-audit.md and .opencode/commands/harness-audit.md. (.opencode/commands/harness-audit.md)
3) [Eval Coverage] Increase automated test coverage across scripts/hooks/lib. (tests/)

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.
