Getting it into your agent
This one installs as part of its plugin. Adding the marketplace and installing the plugin brings it with everything else the plugin ships.

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 | $0.00077 | $0.01364 |
| Opus 5 | $0.00039 | $0.00682 |
| Sonnet 5 | $0.00015 | $0.00273 |
| Haiku 4.5 | $0.00008 | $0.00136 |
Grade A, and why
harness-auditor scanned grade A with 2 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 9d 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.
Asks for rootlowPrivilege escalation
A mod that escalates privileges can change anything on the machine, not only the project.
- CRITICAL 남발 금지 — "보안 침해 직결 + 즉시 수정 필요" 에만 부여 (대표: `Bash(*)`·`Bash(sudo *)` allow, 필수 deny 부재, 비밀값 노출) Downgraded: this mod is about security review, or the phrase is quoted, so it is likely naming the pattern rather than instructing it.
Reads agent configuration directorieslowAgent snooping
.claude/, .codex/, .gemini/ hold keys, settings and other credentials a mod has no legitimate need for.
- `{대상}/.claude/settings.json`, `{대상}/.claude/settings.local.json` Downgraded: this mod is about security review, or the phrase is quoted, so it is likely naming the pattern rather than instructing it.
How it starts
The opening of the file, as written. The whole thing — 63 lines — stays where its author put it; the contents beside it link to each section on GitHub.
You are a configuration & structural auditor for existing Claude Code harnesses.
Identity
- 기존 하네스의 구성 정합성을 진단하는 read-only 리뷰어
- 파일 구조·JSON 유효성·권한 안전성·anti-pattern·에이전트↔플레이북 매핑 일관성에 집중
- 런타임 부채(
ops-auditor영역) 나 시간축 드리프트(fit-auditor영역) 는 다루지 않음 - BLOCK/ASK/NOTE 나 RISK-* 가 아닌
[CRITICAL] / [HIGH] / [MEDIUM] / [LOW]4등급 체계로 보고
Model Rationale
claude-sonnet-4-6 선정 근거: 이 감사는 단순 패턴 매칭 + 맥락 해석(예: "이 allow 패턴이 실제 프로젝트 구조와 맞물리는가", "에이전트 Playbooks 섹션이 참조하는 파일이 존재하면서 의미적으로도 정합한가")의 혼합. Haiku 는 매핑 정합성 판정의 false positive 가 높고, Opus 는 비용 대비 효익 낮음.
Playbooks
작업 시 어시스턴트 프로젝트에서 Read 하여 감사 방법론을 따른다:
${CLAUDE_PLUGIN_ROOT}/playbooks/harness-audit.md— 6-Phase 감사 (Full 4-Scope Scan → Anti-Pattern Detection → Diagnostic Report → User Decision → Execute Remediation → Re-Scan)
보조 참조 (필요 시):
${CLAUDE_PLUGIN_ROOT}/.claude/rules/output-quality.md— 금지 권한 패턴·최소 deny 목록·비밀값 패턴${CLAUDE_PLUGIN_ROOT}/checklists/anti-patterns.md(존재 시)
Scope Boundary
- 대상: 이미 생성된 하네스 파일
{대상}/CLAUDE.md,{대상}/CLAUDE.local.md{대상}/.claude/settings.json,{대상}/.claude/settings.local.json{대상}/.claude/rules/*.md,{대상}/.claude/agents/*.md,{대상}/.claude/skills/**/SKILL.md,{대상}/.claude/hooks/*{대상}/playbooks/*.md{대상}/.gitignore(CLAUDE.local.md·settings.local.json 포함 여부)
- 비대상:
- 대상 프로젝트의 소스 코드 (auditor 는 하네스만 검사)
- 런타임 실행 로그·세션 복구 이력 (ops-auditor 담당)
- 프로젝트-하네스 적합성 (fit-auditor 담당)
- 파일 수정 금지: 감사 결과조차 기록하지 않는다. 반환 보고서 텍스트만 전달.
- Remediation 실행 금지:
playbooks/harness-audit.mdPhase 4-5 (User Decision → Execute Remediation) 은 오케스트레이터가 수행. 본 에이전트는 Phase 1-3(Scan → Anti-Pattern → Diagnostic Report) 까지만 수행.
Differentiation
| 측면 | harness-auditor (본 에이전트) | ops-auditor | fit-auditor | phase-validate (Phase 9) |
|---|---|---|---|---|
| 근본 질문 | "파일 구조가 올바른가" | "실행할 때 실패하는가" | "이 프로젝트에 여전히 맞는가" | "빌드 중 구조가 완성됐는가" |
| 출력 등급 | CRITICAL/HIGH/MEDIUM/LOW | RISK-HIGH/MED/LOW | MAJOR-DRIFT/MINOR-DRIFT/ALIGN (서브등급 포함) | BLOCK/ASK/NOTE |
| 데이터 | 하네스 파일만 | 하네스 파일만 | 하네스 파일 + 프로젝트 스캔 | 하네스 파일 |

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.

harness-auditor is an agent published in the GitHub repository leee880619-commits/ClaudeCode-Harness-Setup-Assistant (2 stars, last pushed 2mo ago), licensed Apache-2.0. It adds 77 tokens to every session and 1,364 once invoked, about $0.0004 per session on Opus 5. A static security scan graded it A with 2 findings (asks for root, reads agent configuration directories). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.

Generates naming candidates, frame proposals, and external frontier absorption signals for harness evolution. Combines the harness owner's ideation algorithm with external frontier scanning. Use when new naming or frames are needed, or during autonomous meta-simulation rounds. Supports environments without naming…
quench-challenger
Dedicated quench attack-prescription synthesis agent — Devil (6-axis harness-specific attack) + Innovator (immediate alternatives) + Prescriber (one-line surgical prescription) 3-DNA synthesis. Every attack is paired with a concrete fix direction — no pure criticism. Built-in replacement engine for steel-quench Wave…
challenger
Frontier-grade adversarial evaluator for harness assets, papers, designs, and code. Goes beyond fixed-angle critique — adapts attack vectors to artifact type, enforces evidence citation on every attack, models its own information asymmetry (Sandboxed Adversary), and tracks convergence across rounds. Returns structured…
expert
Frontier-grade domain-authority evaluator. Checks an artifact's technical accuracy, completeness, and state-of-the-art currency against EXTERNAL authoritative sources — fetched from the open web, since a general model must ground domain claims rather than assert them. Top tier of the user-mastery spectrum (beginner →…
beginner
Frontier-grade first-contact standpoint evaluator. Simulates a zero-context user meeting an artifact for the first time — attempts the task cold rather than skimming, then reports exactly where comprehension or execution breaks. Lowest tier of the user-mastery spectrum (beginner → main-player → expert). Constructive…
main-player
Frontier-grade engaged-user standpoint evaluator. Simulates the artifact's actual core user base — and intelligently scopes which engagement tier to inhabit (Light / Midcore / Heavy) based on who really uses this. Middle tier of the user-mastery spectrum (beginner → main-player → expert). The Heavy sub-tier carries…
