What are Codex skills?
Codex skills are reusable instruction packages that teach an AI coding agent how to perform a specific workflow. A good skill usually includes a SKILL.md file, operating boundaries, examples, tool expectations, and any supporting files needed to make the workflow repeatable.
Direct Answer
Codex skills are reusable instruction packages that teach an AI coding agent how to perform a specific workflow. A good skill usually includes a SKILL.md file, operating boundaries, examples, tool expectations, and any supporting files needed to make the workflow repeatable.
The practical GetSkillary path is to search by intent, compare a real skill package, inspect SKILL.md, and only then download or install it locally.
A concrete starting point is Codebase Analysis Probe, which has a public detail page, package metadata, and manual download guidance.
Best For
- Users evaluating Codex skills with a local AI agent.
- Teams that want reusable workflow instructions instead of one-off prompts.
- Agents that need structured discovery through a website, LLM file, or MCP query.
Not For
- Automatic installation without reading the package first.
- Credential, regulated, or destructive workflows that require a separate review policy.
- Broad task requests where no specific skill, input, or expected output is known.
Example Workflow
- Search with: Codex Skills.
- Open Codebase Analysis Probe and compare its summary, use cases, tags, size, and SHA-256 package hash.
- Download manually from https://codex-skills-downloads.edenxwang2.workers.dev/downloads/codebase-analysis-probe.zip, inspect SKILL.md, then add it to the local skills directory if it matches the task.
MCP Search Query
Use this query when a local AI agent needs structured GetSkillary results for this intent.

Actual Skill Example
Start with Codebase Analysis Probe, then compare the related skills below before downloading. The public detail page is the source of truth for package size, tags, use cases, SHA-256, and manual download status.
The short definition
A Codex skill is a portable workflow module for an AI agent. Instead of rewriting the same instructions every time, the agent can read the skill and apply a consistent process for tasks such as code review, PDF parsing, GitLab automation, SQL optimization, or document conversion.
The useful part is not only the prompt text. A skill can define when it should be used, what files or tools it depends on, how to verify the output, and what safety limits apply before the agent takes action.
What a skill should contain
A practical skill should have a clear name, a description, a trigger condition, step-by-step operating guidance, and examples or references when the task is complex. It should also explain operating limits, such as secrets, destructive commands, paid APIs, or local file changes.
GetSkillary packages public skills as downloadable zip files so users can inspect the contents before using them in a local agent environment.
FAQ
Which skill should I start with for Codex skills?
Start by inspecting Codebase Analysis Probe. It is linked from this page so you can compare the detail page, use cases, tags, package size, and manual download path before installing anything.
Can the MCP endpoint install this skill automatically?
No. The GetSkillary MCP endpoint is a discovery layer. It can search, inspect, recommend, and return manual download guidance, but installation remains user-controlled.
What should I check before enabling a downloaded skill?
Extract the zip into a temporary folder, read SKILL.md, confirm the requested tools and permissions, and test the skill on a small non-critical task first.
