Install

Works with every agent the skills CLI supports.

npx skills add https://github.com/moizibnyousaf/ai-agent-skills --skill skill-creator
  1. 01

    Install

    Run the command in your project. The CLI asks which agents to install for.

  2. 02

    Describe the task

    Ask your agent for something this skill covers. It loads skill-creator automatically when relevant.

  3. 03

    Review the result

    The agent follows the SKILL.md steps, scripts and references bundled with the skill.

SKILL.md

The instructions your agent reads when the skill is triggered.

Skill Creator

Skills are modular packages that extend Claude's capabilities by providing specialized knowledge, workflows, and tools.

Core Principles

Concise is Key

The context window is a shared resource. Only add context Claude doesn't already have. Challenge each piece: "Does Claude really need this?"

Anatomy of a Skill

Skill Creation Process

Step 1: Understand with Examples

Gather concrete examples of how the skill will be used. Ask:

  • "What functionality should this skill support?"
  • "What would a user say that should trigger this skill?"

Step 2: Plan Reusable Contents

Analyze examples to identify:

  • Scripts: Code that gets rewritten repeatedly
  • References: Documentation Claude needs to reference
  • Assets: Templates, images for output

Step 3: Initialize

Create the skill directory structure with SKILL.md and resource folders.

Step 4: Implement

  • Start with reusable resources (scripts, references, assets)
  • Write clear SKILL.md with proper frontmatter
  • Test scripts by actually running them

Step 5: Iterate

Use the skill on real tasks, notice struggles, improve.

Progressive Disclosure

Keep SKILL.md under 500 lines. Split content:

# PDF Processing

## Quick start
[code example]

## Advanced features
- **Form filling**: See [FORMS.md](FORMS.md)
- **API reference**: See [REFERENCE.md](REFERENCE.md)

What NOT to Include

  • README.md
  • INSTALLATION_GUIDE.md
  • CHANGELOG.md
  • User-facing documentation

Skills are for AI agents, not humans.

google-agents-cli-publish

google/agents-cli

This skill should be used when the user wants to "publish an agent", "publish my ADK agent", "register an agent with Gemini", "publish to Gemini" (formerly Gemini Enterprise), or needs guidance on the agents-cli publish gemini command. Also use when the user wants to "manage agents in Agent Registry", "list/update/delete registered agents", or "register an MCP server". Covers ADK vs A2A registration modes, programmatic and interactive usage, flag reference, auto-detection from deployment metadata, Agent Registry fleet management, and troubleshooting. Part of the agents-cli skills suite. Do NOT use for deployment (use google-agents-cli-deploy).

google-agents-cli-eval

google/agents-cli

This skill should be used when the user wants to "run an evaluation", "evaluate my agent", "evaluate my ADK agent", "write an eval dataset", "analyze eval failures", "compare eval results", "optimize agent", or needs guidance on the Gemini platform eval methodology and the Quality Flywheel. Covers eval metrics, dataset schema, LLM-as-judge scoring, and common failure causes. Applies to any agents-cli project, whatever framework the agent is written in. Do NOT use for agent API code patterns (ADK: use google-agents-cli-adk-code), deployment (use google-agents-cli-deploy), or project scaffolding (use google-agents-cli-scaffold).

codex-pet

prime-skills/runcomfy-agent-skills

Codex Pet generator on RunComfy. Build a Codex-compatible Codex Pet spritesheet.webp + pet.json from a single reference image, drop it into ${CODEXHOME:-$HOME/.codex}/pets/ / and Codex picks it up as a custom Codex Pet next to the 8 built-ins. This skill produces the exact Codex Pet atlas Codex expects (1536x1872 PNG/WebP, 8 cols x 9 rows, 192x208 cells, 9 animation states — idle, running-right, running-left, waving, jumping, failed, waiting, running, review). Calls OpenAI GPT Image 2 edit ONCE via the local RunComfy CLI as runcomfy run openai/gpt-image-2/edit to produce a canonical Codex Pet pose, then assembles all 9 animation rows programmatically with ImageMagick micro-transforms — no Codex Pro, no $imagegen, no OPENAIAPIKEY required, only RUNCOMFYTOKEN. Triggers on "codex pet", "create codex pet", "make codex pet", "hatch codex pet", "/hatch image", "desktop pet codex", "codex pets", "spritesheet.webp", or any explicit ask to build a custom pet for OpenAI Codex.
