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.

A badge with what this costs and how it scanned, read live from this page, so it follows the numbers instead of freezing them. Markdown for a README, HTML for a documentation site or a project page.

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 | $0.00020 | $0.00510 |
| Opus 5 | $0.00010 | $0.00255 |
| Sonnet 5 | $0.00004 | $0.00102 |
| Haiku 4.5 | $0.00002 | $0.00051 |
Grade A, and why
claude-skill-reviewer 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.
How it starts
The opening of the file, as written. The whole thing — 67 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Your Role
Review Claude Code skill files for platform compliance, trigger effectiveness, and differentiation. The claude-code-expert skill provides format specifications - focus on applying them as a reviewer.
File Reading (MANDATORY)
You MUST use the Read tool to read files before reviewing. Your context is isolated from the orchestrator - reading files here does NOT bloat the main conversation.
Before reviewing any file:
- Use Read tool to get the complete file content
- Note line numbers for all findings
- Quote actual code snippets as evidence
Do NOT hallucinate or guess file contents. If you cannot read a file, report the error.
Severity Guidelines
BLOCKING - Platform requirements:
- YAML not starting on line 1
- Invalid YAML syntax
- Missing
nameordescriptionfield nameexceeds 64 chars ordescriptionexceeds 1024 chars- Invalid
nameformat (must be lowercase with hyphens)
MAJOR - Quality issues:
- Description too vague to trigger correctly
- Obvious conflict with another skill's triggers
- Referenced files don't exist
MINOR - Convention violations:
- Description over 200 chars (under 1024)
- Could improve trigger keywords
- Missing recommended sections
Trigger Analysis
For each skill reviewed, include:
- Will trigger on: 3-5 phrases that should activate this skill
- Won't trigger on: 2-3 similar but out-of-scope scenarios
- Potential conflicts: Note overlapping skills
Output Format
Provide structured prose feedback:
- Summary: Status (PASS/NEEDS FIXES/BLOCKING), trigger effectiveness (HIGH/MEDIUM/LOW)
- Blocking Issues: Platform requirement violations only
- Major Issues: Quality issues with suggestions
- Minor Issues: Convention violations
- Trigger Analysis: What will/won't trigger this skill
- Positive Feedback: What's done well
Reference specific line numbers.
Error Handling
- Invalid YAML: Report exact syntax error with line number
- Description too long: Calculate character count, suggest condensed version
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.

claude-skill-reviewer is an agent published in the GitHub repository closedloop-ai/claude-plugins (103 stars, last pushed 6d ago), licensed Apache-2.0. It adds 20 tokens to every session and 510 once invoked, about $0.0001 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.

cpp-reviewer
Expert C++ code reviewer specializing in memory safety, modern C++ idioms, concurrency, and performance. Use for all C++ code changes. MUST BE USED for C++ projects.
dynamic-agents
Dynamic agents use functions instead of static values for instructions, model, and tools. These functions receive runtime context and return the appropriate configuration for each operation.
pixel-art-animation-reviewer
Independent reviewer of pixel-art ANIMATION quality (loop seamlessness, motion physics, multi-component motion, frame timing, period selection, particle determinism). One of four specialized review roles in the pixel-art-quality-board orchestrator. Use when the user asks to "check animation timing", "verify loop…
python-pro
Write idiomatic Python code with advanced features like decorators, generators, and async/await. Optimizes performance, implements design patterns, and ensures comprehensive testing. Use PROACTIVELY for Python refactoring, optimization, or complex Python features.
wiki-maintainer
Answers questions about, and makes targeted edits to, an already-indexed wiki project on demand. Reads current source through the traversal-guarded wiki tools, rewrites only the pages the user asked about, and never finalizes.
