In plain words
What is it for?
It is for checking instruction length and indexes, rule-enforcing hooks, shared documents, installed skills, hook scripts, document freshness, and an overall score.
Why use it?
It reveals missing, outdated, invalid, or poorly enforced parts of the setup before they cause inconsistent agent work.

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 8d 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

Harness 健康審計

週期性檢查專案 Harness(CLAUDE.md + Hook + Skill + Knowledge)的健康狀態。

使用方式

/harness-audit

參數

無(操作當前專案)

檢查項目(七大原則)

原則 1: 上下文架構(給地圖不給百科全書)

  • CLAUDE.md 行數 ≤ 100(超過 = 警告)
  • CLAUDE.md 有文件索引且索引完整
  • .knowledge/ 文件都在索引中登記

原則 2: 架構約束(用工具強制不靠 prompt)

  • 掃描 CLAUDE.md 中的「禁止」「不得」等文字規則
  • 檢查是否有對應 Hook 強制(.claude/settings.json)
  • 未被 Hook 覆蓋的文字規則列出建議

原則 3: 知識層級(公司 vs 專案)

  • .knowledge/company-rules.md 存在
  • .knowledge/team-workflow.md 存在
  • 專案級規範與公司級不衝突

原則 4: 技能即流程(Skill 覆蓋)

  • ~/.claude/commands/ 或 .claude/commands/ 目錄存在且有 skill 檔案
  • 掃描已部署的 Skill 數量
  • 列出未部署但可用的公司 Skill(對照 AgentHub skill-templates/)

原則 5: Hook 健康

  • .claude/settings.json 存在且 JSON 合法
  • Stop hook 存在
  • PreToolUse hook 存在(forbidden-commands)
  • Hook 腳本檔案存在且可執行

原則 6: 文件新鮮度

  • .knowledge/ 下各文件最後修改日期
  • 超過 30 天未更新的文件標記為「可能過時」

原則 7: 整體評分

  • 每個原則 0-2 分(0=缺失, 1=部分, 2=完善)
  • 總分 /14,≥10 = 健康,7-9 = 需改善,<7 = 警告

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.
