Ran a real review of a toy notes-cli spec: the skill's rubric flagged two concrete defects a generic baseline review missed entirely -- an interactive-browser-only login with no delegatable-token path (Principle 7) and no idempotency key on the add command (silent duplicate notes on agent retry) -- and returned a reproducible 3/28 'not yet agent-native' score instead of a vague impression.

Scored on four weighted criteria — install, triggering, output vs. baseline, docs. How scoring works

  • Installs cleanly 5/5
  • Triggers reliably 5/5
  • Output vs. baseline 9/10
  • Docs & honesty 5/5

What Agent Native Design does

Reviews, designs, or refactors CLIs meant to serve humans, AI agents, and orchestrators at once -- checking stdout/JSON contracts, exit codes, self-description, dry-run, safety tiers, auth delegation, and idempotency against a scored 14-criterion rubric mapped to seven design principles. Triggers on requests to evaluate whether a CLI is agent-native, convert an API/SDK into an agent-usable CLI, or refactor a human-only CLI's output/help/error contracts.

How to install Agent Native Design

git clone https://github.com/Agents365-ai/agent-native-design.git
mkdir -p ~/.claude/skills
cp -r agent-native-design/skills/agent-native-design ~/.claude/skills/agent-native-design

Skills live in ~/.claude/skills/ (global) or .claude/skills/ (per-project). Restart Claude Code after installing.

Commands — how to trigger Agent Native Design

  • /agent-native-design Scores a CLI on a 14-criterion rubric across seven agent-native design principles and produces a prioritized P0/P1/P2 refactor plan.

It also activates on plain-language prompts like these:

  • Is my CLI actually usable by an AI agent, not just a human typing?
  • Review whether this API's command-line wrapper is agent-native
  • Score my tool's stdout, exit codes, and auth flow for agent friendliness

Can I use Agent Native Design with Cursor, Copilot, Gemini CLI, Codex or other AI tools?
The SKILL.md format is native to Claude (Claude Code, Desktop, claude.ai). The instructions inside adapt to other assistants: Cursor rules, GitHub Copilot instructions, Windsurf rules, Custom GPTs, AGENTS.md for OpenAI Codex, and GEMINI.md for Google Gemini CLI — our conversion guides cover each, and the free converter on the tools page does the wrapping for you.
