Find, Audit, and Build Agent Skills
Move from a concrete job to package review, a small controlled test, and a reusable Skill with a clear activation boundary.
Your job
I need an Agent Skill I can inspect, test, and use for a defined job.
Where to start
Audit an existing package before installation, or create a focused Skill for a job you already understand.
Choose a route
Start with the result you need
Use the condition that matches your work, then check the named output before moving on.
You already know the job and want to author your own Skill.

Check: Test that the Skill activates for its intended task and stays out of unrelated work.
You want to use the same package in Codex and Grok Build.
Read: Can One Agent Skill Work in Both Codex and Grok Build?
Check: Recheck discovery, invocation, and permissions in each host.
You need to choose between a Codex Skill and a Gemini Gem.
Read: Gemini Gems vs Codex Skills: Which Reusable AI Workflow Fits?
Check: Choose by the recurring job and the host where it must run.
Before you move on: Package inspection is the first gate, not proof of safe behavior. Record what the Skill can access, run the smallest relevant test, and keep host-specific permission decisions explicit.
