skill-reviewer

skill-reviewer is a skill for Claude Code, Codex from niracler/skill. It costs 126 tokens per session (1,223 once invoked), scanned A, original, MIT.

A checker for Claude Code skills, which are instruction files that guide an AI coding agent through particular tasks.

In plain words
What is it for?
Use it to validate skill files, assess their content quality, check platform and agent compatibility, and verify that their descriptions trigger at the right times.
Why use it?
It can reveal structural problems, weak triggering descriptions, missing prerequisites, and compatibility issues across coding agents and operating systems.

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

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 3d ago.

The scan reads SKILL.md. This mod also ships 2 executable files (scripts/quick_validate.py, scripts/validate.sh), listed below but not scanned — reading those needs a real analyzer, not pattern matching.

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 Reviewer

审计 Claude Code skills 的质量和兼容性。作为编排器,委托已有工具处理结构/质量检查,自身专注兼容性审计。

Prerequisites

Tool Type Required Install
skill-creator skill Yes Built-in on most AI coding agents (Claude Code, Cursor, etc.)

Do NOT proactively verify these tools on skill load. If a command fails due to a missing tool, directly guide the user through installation and configuration step by step.

审计流程

Step 1: 结构校验(委托)

运行 skill-reviewer 自带的校验脚本,汇总 YAML frontmatter、name 格式、description 格式等结果:

bash <skill-reviewer-dir>/scripts/validate.sh

若脚本不可用(如未通过 npx skills 安装),手动检查每个 SKILL.md 的 YAML frontmatter:name(hyphen-case,≤64 字符)、description(无尖括号,≤1024 字符)。

Step 2: 内容质量(委托)

MUST 执行:调用 skill-creator skill 进行深度质量审查(token 效率、渐进式披露、反模式、description 基准测试等)。

skill-creator 不可用,MUST 停下并引导用户确认,不得跳过。大多数 AI 编码 agent 内置了 skill-creator:

  • Claude Code: document-skills:skill-creatorskill-creator:skill-creator
  • 其他 agent: 检查对应的 skill 管理功能

此步骤不可跳过。没有 skill-creator 的审计是不完整的。

Step 3: 兼容性审计(自身核心)

references/compatibility-checklist.md 逐项检查目标 skill 的所有文件(SKILL.md + scripts/ + references/):

3a. 跨平台兼容性 — 扫描平台锁定模式(macOS-only 命令、Windows 不兼容项等)。

3b. 跨 Agent 兼容性 — 检测 Claude Code 专属工具引用和 MCP 依赖。

3c. npx skills 生态兼容性 — 校验 marketplace.json 注册、symlink 可用性、跨 skill 依赖。

3d. 工具引用规范 — 检查是否保留了 Claude Code 工具术语并提供了其他环境的 fallback 备注。详见 checklist 的 "Tool Reference Best Practices" 部分。

3e. Prerequisites 声明 — 检查 SKILL.md 是否声明了外部依赖:

  • 如果 skill 使用了外部 CLI 工具(git, gh, reminders-cli 等)、MCP 服务器、或其他 skill,MUST 有 ## Prerequisites 章节
  • Prerequisites 必须是 body 中第一个 ## 章节
  • 章节内 MUST 包含 4 列表格:Tool / Type / Required / Install
  • Type 列 MUST 使用标准值:cli, mcp, skill, system
  • 表格后 MUST 有被动检查说明(blockquote),明确要求在执行失败时直接引导用户完成安装配置,而非指向外部文档
  • 需要配置的工具(如 MCP 服务器、需要 auth 的 CLI)SHOULD 在 Install 列提供可执行的安装命令和配置步骤,或引用 skill 自带的 references/ 文档
  • 无外部依赖的 skill 不需要此章节

Files

What ships with it

3 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.

Changes

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-reviewer is a skill published in the GitHub repository niracler/skill (11 stars, last pushed 1mo ago), licensed MIT. It adds 126 tokens to every session and 1,223 once invoked, about $0.0006 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.
