skills

Agent skills I use, packaged so they work with Claude (Code, Desktop, claude.ai), Codex / ChatGPT, Cursor, GitHub Copilot, Gemini CLI and any other tool that supports the open Agent Skills format.

A skill is a folder with a SKILL.md (instructions plus a description that tells the agent when to use it). Some skills also include references/ (docs the agent reads when it needs them) and scripts/ (helpers the agent runs).

Skills

Annotation

• website-judgment-auditor: Audit hand-written Website A vs Website B justifications against the task rules, without rewriting them. Manual-only: name the skill, or paste the Request: / Selected: / Aesthetics: / Functionality: / Overall: template.

Install

Pick one method per tool. If you install the same skill twice, the agent sees duplicates.

Claude Code (plugin, auto-updates)

claude plugin marketplace add jechav/skills
claude plugin install jechav-skills@jechav

Or, from inside a session: /plugin marketplace add jechav/skills, then /plugin install jechav-skills@jechav.

Codex, Cursor, Copilot, Gemini CLI and 40+ other agents

npx skills@latest add jechav/skills

The installer asks which skills to install and which agents to install them for. To install just one skill:

npx skills@latest add jechav/skills --skill website-judgment-auditor

The skills are copied into your project (or into your home directory with -g) as editable files. Run npx skills update to pull new versions.

claude.ai, Claude Desktop, and ChatGPT (upload a zip)

1. Download <skill-name>.zip from the latest release.
2. Claude: go to Settings, then Capabilities, then Skills, and upload the zip. ChatGPT: if your plan supports skills, upload the same zip in the skills settings.

Any other chatbot (copy and paste)

Paste the contents of the skill's SKILL.md and its references/*.md into a Project's or custom GPT's instructions. The scripts/ only automate checks that SKILL.md already describes in prose, so the skill still works without them, just less precisely.

Adding a skill

See CONTRIBUTING.md. Short version:

scripts/new-skill.sh <bucket> <skill-name>   # scaffold and register
scripts/validate.sh                          # check everything is wired up
