Skills, templates and checklists for you and your agent
Is the skill ready?
Check a skill’s purpose, content, activation, and boundaries on realistic requests.
Evaluate a source
Separate original evidence from retellings and assess its relevance to the question.
Prepare inputs for an agent
Provide useful context and files while preserving structure, versions, and sensitive information.
Why is the agent stuck?
Identify rules that cause unnecessary reading, repeated checks, or premature stops.
Website release checklist
Walk through links, forms, mobile layouts, downloads, and failure states before publishing.
FIRST RUNFrom file
From file
to useful work.
- Choose one skill
Extract its folder into .agents/skills in your Codex project. Each skill folder contains SKILL.md. Select it in the interface; in CLI and IDE you can invoke it with $skill-name.
- Add your task
Each resource includes an example prompt. Supply your files, constraints, and expected result. Templates and checklists can be used directly in a chat.
- Try a small example
Compare the output with your source material and adapt the instructions to your workflow. A skill guides the work; your agent provides file, browser, and other tool access.
