EGC: Command for Claude Code

.opencode/commands/harness-audit.md

harness-audit is a command for Claude Code, OpenCode from Fmarzochi/EGC. It costs 0 tokens per session (586 once invoked), scanned A, a copy of harness-audit, Apache-2.0.

A deterministic repository audit that checks a project against fixed categories and returns a prioritized scorecard.

In plain words
What is it for?
Use it to audit the whole repository or specific hooks, skills, commands, or agents in text or JSON format.
Why use it?
It shows where the repository's tooling, quality checks, memory, evaluation, security, and cost controls are weak.

Command for Claude CodeOpenCode

Written for Claude Code and OpenCode: $ARGUMENTS substitution, but also installed under .opencode/. Also seen: mentions OpenCode.

This is Fmarzochi/EGC's own configuration. It tells Claude Code and OpenCode how to work on EGC 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 EGC configures →

Needs its repository: it runs a file that does not travel with it, so clone the repository first. The line is node scripts/harness-audit.js <scope> --format <text|json> [--root <path>].

Reuse

Borrowing it

Nothing to install: this file belongs to Fmarzochi/EGC. Take a copy, put it at the same path in your own repository, and replace the rules that are about this project with yours.

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

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 4d 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.

Origin

Harness Audit Command

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

Usage

/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):

  1. Tool Coverage
  2. Context Efficiency
  3. Quality Gates
  4. Memory Persistence
  5. Eval Coverage
  6. Security Guardrails
  7. 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 EGC repo itself or a consumer project using EGC.

Output Contract

Return:

  1. overall_score out of max_score (70 for repo; smaller for scoped audits)
  2. Category scores and concrete findings
  3. Failed checks with exact file paths
  4. Top 3 actions from the deterministic output (top_actions)
  5. Suggested EGC 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/)

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.
