About prompt
This tool is a prompt designed to guide an AI in generating custom, portable Codex skills from recurring workflows. It follows OpenAI's Agent Skills format and produces artifacts such as SKILL.md (with YAML frontmatter and imperative instructions), optional agents/openai.yaml for UI metadata and invocation policy, and optional scripts/ for deterministic behavior. The prompt emphasizes single-responsibility skills, precise descriptions for safe implicit invocation, and includes safety boundaries and a verification checklist. It is part of the ai-boost/awesome-prompts open-source collection.

Open source and part of curated awesome-prompts collection
Pros & Cons
Pros
- Focuses on single-responsibility skills for clarity and reusability
- Includes safety constraints to prevent misuse or unintended actions
- Provides structured output artifacts (YAML, scripts) for easy integration
- Designed for both explicit ($skill-name) and implicit (description match) invocation
- Part of a curated open-source repository with 8.5k stars
Cons
- Requires familiarity with OpenAI Codex Skills format and YAML
- Output is a text file; no interactive UI or automated deployment
- Relies on AI interpretation to generate accurate skill files
- Not a standalone tool; must be used within an AI context (e.g., ChatGPT)
Best For
Creating reusable Codex skills for recurring development workflowsStandardizing agent behavior across projects with portable skill filesAutomating routine coding tasks with AI assistants using CodexDefining safe invocation boundaries and dependency requirements for skills
FAQ
What artifacts does this prompt produce?
It produces SKILL.md with YAML frontmatter and instructions, optionally agents/openai.yaml for UI metadata and tools, and optionally scripts/ for deterministic code.
How does implicit invocation work?
Codex selects the skill based on the description match. The prompt requires precise descriptions so that implicit invocation is safe and the skill is only triggered for its intended workflow.
What are the design rules for skills?
One skill, one job. Descriptions must be front-loaded with trigger words for truncation resilience. Steps should be explicit inputs/outputs. Safety boundaries and a verification checklist must be included.
Can the skill include scripts?
Yes, an optional scripts/ directory can be included if the workflow needs deterministic code or external CLI calls. Each script must have a clear contract for arguments, stdout, stderr, and exit codes.
