skilldoctor

Quality gate for Agent Skills. Lint the spec, audit unsafe instructions, and check whether a SKILL.md actually works on Claude Code, Cursor, Codex, OpenCode, Gemini CLI, and GitHub Copilot.

Agent Skills 的质量门禁：校验官方规范、审计危险指令，并检查同一个 SKILL.md 在 Claude Code、Cursor、Codex、OpenCode、Gemini CLI、GitHub Copilot 上能不能移植。

Vercel npx skills installs skills. skilldoctor decides whether you should keep them.

Vercel 的 npx skills 负责安装。skilldoctor 负责判断该不该留。

cd skilldoctor
npm install
npm run build
node dist/cli.js --help

Requires Node.js 18.18 or newer.

Commands / 命令

npx --yes github:xyiqq/skilldoctor lint ./my-skill
npx --yes github:xyiqq/skilldoctor audit ./my-skill
npx --yes github:xyiqq/skilldoctor compat ./my-skill
npx --yes github:xyiqq/skilldoctor ci ./my-skill
npx --yes github:xyiqq/skilldoctor scan
npx --yes github:xyiqq/skilldoctor init pdf-processing
npx --yes github:xyiqq/skilldoctor rules
npx --yes github:xyiqq/skilldoctor explain lint/name-invalid
npx --yes github:xyiqq/skilldoctor fix ./my-skill
npx --yes github:xyiqq/skilldoctor fix ./my-skill --dry-run
npx --yes github:xyiqq/skilldoctor score ./my-skill

scan is also available as skilldoctor doctor.

path can be one skill directory or a repository root. skilldoctor walks the tree and finds every SKILL.md.

path 可以是单个 Skill 目录，也可以是仓库根目录。skilldoctor 会向下查找全部 SKILL.md。

Options / 参数

skilldoctor ci . --format json --fail-on warning
skilldoctor ci . --ignore examples --format markdown
skilldoctor score . --fail-on score:80

Optional config files in the repo root / 仓库根目录可选配置：

{
  "failOn": "error",
  "ignore": ["vendor/skills"]
}

.skilldoctorignore uses one path prefix per line. # comments are skipped.

.skilldoctorignore 每行一个路径前缀，# 开头是注释。

Example / 示例

skilldoctor ci  1 skill(s)

✔ release-notes  examples/release-notes

1 skills  0 errors  0 warnings  0 info

A failing audit looks like this / 失败的审计类似：

✖ audit-injection  test/fixtures/audit-injection
  error  audit/prompt-injection  SKILL.md:8  instructions try to override system or hidden-user policy

What it checks / 检查什么

• lint — name, description, directory match, YAML, metadata types, 500-line budget, broken references/ / scripts/ / assets/ links
• audit — prompt injection, hardcoded secrets, credential paths, Bash(*), curl | sh, dump hosts, self-modifying skills
• compat — which frontmatter fields survive outside Claude Code
• scan — skills already installed for local agents, including duplicate names

Rule IDs are stable: docs/RULES.en.md / docs/RULES.zh-CN.md

Why not another installer? / 为什么不再做安装器？

The installer slot is taken. This tool is the missing CI gate: authors add one command, reviewers see annotations, users run audit before a skill touches ~/.codex/skills.

安装器赛道已经有人占了。这个工具补的是 CI 门禁：作者加一条命令，审查者能在 PR 里看到 annotation，用户在 Skill 进 ~/.codex/skills 之前先跑 audit。

Development / 开发

npm install
npm test
npm run build
node dist/cli.js lint examples
