Install

Works with every agent the skills CLI supports.

npx skills add https://github.com/openai/openai-agents-js --skill changeset-validation
  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 changeset-validation 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.

Changeset Validation

Overview

This skill validates whether changesets correctly reflect package changes and follow the repository rules. It relies on the shared prompt in references/validation-prompt.md so local Codex reviews and GitHub Actions share the same logic. Experimental or preview-only feature additions that are explicitly labeled as such in the diff may remain a patch bump when they do not change existing behavior. Major bumps are only allowed after the first major release; before that, do not use major bumps for feature-level changes.

Quick start

Local (Codex-driven):

  1. Run:
    pnpm changeset:validate-prompt
    
  2. Apply the rules from references/validation-prompt.md to the generated prompt.
  3. Respond with a JSON verdict containing ok/errors/warnings/required_bump (English-only strings).

CI (Codex Action):

  1. Run:
    pnpm changeset:validate-prompt -- --ci --output .github/codex/prompts/changeset-validation.generated.md
    
  2. Use openai/codex-action with the generated prompt and JSON schema to get a structured verdict.

Workflow

  1. Generate the prompt context via pnpm changeset:validate-prompt.
  2. Apply the rules in references/validation-prompt.md to judge correctness.
  3. Provide a clear verdict and required bump (patch/minor/major/none).
  4. If the changeset needs edits, update it and re-run the validation.

Branch-level changeset rule (do not skip)

  • If any .changeset/*.md file is already present in the current branch diff, treat it as the active changeset. Do not add a new changeset file.
  • Instead, update the existing changeset file by rewriting its summary to reflect the primary change relative to main. Do not try to capture every incremental update.
  • Keep the summary at one line; replace the line as needed rather than appending. If you must include multiple points, compress them into a single line.

Shared source of truth

  • Keep the prompt file as the single source of validation rules.
  • Keep the script lightweight: it should only gather context and emit the prompt.

How do I install changeset-validation?

Run npx skills add https://github.com/openai/openai-agents-js --skill changeset-validation in your project. The skills CLI detects the agents you use and copies the skill into the right folder. For Claude Code you can also place the skill folder at ~/.claude/skills/changeset-validation/ (personal) or .claude/skills/changeset-validation/ (project).

Which AI agents can use changeset-validation?

Any agent that supports the open Agent Skills format (a folder with a SKILL.md file), including Claude Code, Codex, Cursor, GitHub Copilot, Gemini CLI, Windsurf, Cline, OpenCode and more.

Is changeset-validation safe to install?

No partner security audit is available yet. Skills can run commands and scripts, so read the SKILL.md and any bundled files before installing.

Who maintains changeset-validation?

It is published by openai in openai/openai-agents-js, and it is an official skill from the maker of the technology it covers. It has 127 recorded installs.

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).

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.
