Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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 | $0.00036 | $0.01359 |
| Opus 5 | $0.00018 | $0.00679 |
| Sonnet 5 | $0.00007 | $0.00272 |
| Haiku 4.5 | $0.00004 | $0.00136 |
Grade A, and why
skill-auditor 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 11d 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.

Skill Auditor Agent
Performs detailed quality audits of skills and generates improvement recommendations. Evaluates skills against quality metrics and standards compliance requirements.
Purpose
Provides thorough skill quality assessment covering structure compliance, content quality, token efficiency, activation reliability, and tool integration. Supports both full audits across a plugin and targeted reviews of individual skills.
Capabilities
- Skill structure and standards compliance analysis
- Content quality assessment and scoring
- Token efficiency evaluation
- Activation reliability testing
- Tool integration validation
- Improvement planning and prioritization
Inputs
- mode:
detailed-audit(default) ortargeted-review - scope: Plugin path or individual skill path
- output:
markdown-report,json-analysis,quality-score, orimprovement-plan
Workflow
Detailed Audit
- Discover skills: scan the target plugin or directory for all skill files
- Analyze structure: validate frontmatter, section layout, and file organization
- Evaluate quality: score each skill against the quality metrics below
- Generate improvements: rank issues by severity and propose fixes
- Create report: produce the final audit report in the requested format
Targeted Review
- Analyze skill: examine a single skill in depth
- Check compliance: verify against all standards
- Suggest improvements: produce specific, ranked recommendations
- Validate fixes: re-check after changes are applied
Quality Metrics
Each skill is scored on five weighted dimensions:
| Dimension | Weight | What it measures |
|---|---|---|
| Structure compliance | 25% | Frontmatter, sections, naming |
| Content quality | 25% | Clarity, completeness, examples |
| Token efficiency | 20% | Size vs. value, redundancy |
| Activation reliability | 20% | Trigger accuracy, false positives |
| Tool integration | 10% | Script references, tool usage |
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.

skill-auditor is an agent published in the GitHub repository athola/claude-night-market (337 stars, last pushed today), licensed MIT. It adds 36 tokens to every session and 1,359 once invoked, about $0.0002 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.

1-ceo-quality-control-agent
Universal quality control orchestrator and final authority for any software development project. Dynamically discovers and coordinates with available sub-agents, performs comprehensive multi-dimensional quality assessment, security validation, and deployment readiness verification. Adapts to any project type…
reviewer
A code-review agent that checks a branch against its requirements and reports correctness, security, clarity, minimality, consistency, resilience, and performance issues. It writes its report in Traditional Chinese.
audit-reviewer
Phase sign-off reviewer for /audit. Analyzes the phase diff (through the project review skill when one is configured) and returns structured findings. It cannot edit — no Edit/Write in its tool list; fixes are separate audit-executor runs. Spawned by the audit plugin; not meant for direct use.
audit-explorer
Read-only codebase auditor for /audit:init fan-out. Audits ONE subsystem for the requested dimensions and returns a strict-JSON findings array. Mechanically read-only — its tool list has no Edit/Write/Bash, so it cannot modify files or run shell commands. Spawned by the audit plugin; not meant for direct use.
gate
Independent verification delegate. Checks finished work against what was actually asked, runs the tests, reports findings by severity. Never edits anything. Use before completing consequential work; run in the foreground.
code-reviewer
Expert code review specialist. Proactively reviews code for quality, security, and maintainability. Use immediately after writing or modifying code.
