Agent Skills Standard CLI

Sync 237 AI coding standards to any project in one command. Works with Cursor, Claude Code, GitHub Copilot, Gemini, Windsurf, Trae, Kiro, and Roo.

npx agent-skills-standard@latest init   # detect your stack
npx agent-skills-standard@latest sync   # install skills

What It Does

The CLI takes engineering standards from the Agent Skills Standard registry and installs them into your AI agent's native format:

npx agent-skills-standard sync

  - Updated .cursor/skills/    (Cursor)
  - Updated .claude/skills/    (Claude Code)
  - Updated .github/skills/    (Copilot)
  - Generated _INDEX.md for 8 categories.
  - AGENTS.md router index updated.

The result: your AI agent reads AGENTS.md, follows the router to the right category, and loads only the skills that match what you're editing.

Commands

| Command | What it does | | :--------- | :--------------------------------------------------------------------------------------------- | | init | Detects your tech stack (Flutter, React, Go, etc.) and creates a .skillsrc config | | sync | Fetches skills from the registry, writes to agent folders, generates _INDEX.md + AGENTS.md | | validate | Checks your custom skills against format and token standards | | feedback | Submits improvement suggestions to the registry | | upgrade | Updates the CLI to the latest version |

Configuration

The .skillsrc file controls everything:

registry: https://github.com/HoangNguyen0403/agent-skills-standard
agents: [cursor, copilot, claude]
skills:
  react:
    ref: react-v1.3.1
  golang:
    ref: golang-v1.3.1
    exclude: ['golang-tooling'] # skip skills you don't need
  common:
    ref: common-v2.0.1
    custom_overrides: ['common-tdd'] # protect your local edits

What Gets Generated

After sync, your project contains:

project/
  AGENTS.md                           # Router table (~20 lines)
  .cursor/skills/
    golang/_INDEX.md                  # Trigger table for Go skills
    golang/golang-language/SKILL.md   # The actual skill
    golang/golang-testing/SKILL.md
    react/_INDEX.md                   # Trigger table for React skills
    react/react-hooks/SKILL.md
    ...

AGENTS.md maps file extensions to category indexes. _INDEX.md has two sections: File Match (auto-check against your file) and Keyword Match (activates when you mention a concept). SKILL.md is the skill itself — loaded on demand, averaging ~500 tokens.

Privacy & Security

• Text only — the CLI downloads Markdown and JSON files, never binaries or scripts
• No telemetry — zero data collection, no background processes
• Transparent — fetches from the public registry, nothing hidden
• Override protection — custom_overrides prevents the CLI from touching your local modifications
