Q: How do I install write-a-skill?

Run npx skills add https://github.com/vinvcn/mattpocock-skills-zh-cn --skill write-a-skill in your project. The skills CLI detects the agents you use and copies the skill into the right folder.

Install

Works with every agent the skills CLI supports.

npx skills add https://github.com/vinvcn/mattpocock-skills-zh-cn --skill write-a-skill

01
Install
Run the command in your project. The CLI asks which agents to install for.
02
Describe the task
Ask your agent for something this skill covers. It loads write-a-skill automatically when relevant.
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.

Writing Skills

Process

Gather requirements — 询问用户：
- skill 覆盖什么 task/domain？
- 应处理哪些具体 use cases？
- 需要 executable scripts，还是只需要 instructions？
- 是否有 reference materials 要包含？
Draft the skill — 创建：
- 带 concise instructions 的 SKILL.md
- 如果内容超过 500 行，创建 additional reference files
- 如果需要 deterministic operations，创建 utility scripts
Review with user — 展示 draft 并询问：
- 是否覆盖你的 use cases？
- 是否缺失或不清楚？
- 是否有 section 应更详细或更简短？

# Skill Name

## Quick start

[Minimal working example]

## Workflows

[Step-by-step processes with checklists for complex tasks]

## Advanced features

[Link to separate files: See [REFERENCE.md](REFERENCE.md)]

Description Requirements

description 是 agent 决定是否加载 skill 时唯一看到的内容。它会和其他 installed skills 一起出现在 system prompt 中。agent 会读取这些 descriptions，并根据用户请求选择相关 skill。

Goal：给 agent 足够信息，让它知道：

这个 skill 提供什么 capability
何时/为什么触发它（specific keywords、contexts、file types）

Format：

最多 1024 chars
使用 third person
第一句说明它做什么
第二句："Use when [specific triggers]"

Good example：

Extract text and tables from PDF files, fill forms, merge documents. Use when working with PDF files or when user mentions PDFs, forms, or document extraction.

Bad example：

Helps with documents.

坏例子无法让 agent 区分它和其他 document skills。

When to Add Scripts

以下情况添加 utility scripts：

Operation 是 deterministic（validation、formatting）
同一段 code 会被反复生成
Errors 需要明确 handling

相比 generated code，scripts 节省 tokens 并提升 reliability。

When to Split Files

以下情况拆分为独立文件：

SKILL.md 超过 100 行
内容有不同 domains（finance vs sales schemas）
Advanced features 很少需要

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).

AI & Agents513.9K installs

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).

skill-creator

anthropics/skills

Create new skills, modify and improve existing skills, and measure skill performance. Use when users want to create a skill from scratch, edit, or optimize an existing skill, run evals to test a skill, benchmark skill performance with variance analysis, or optimize a skill's description for better triggering accuracy.

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.
