Practical fit
Codex Skills fit workflows that recur often enough to deserve a named procedure, supporting references, and clear trigger rules. They are most valuable when the method matters, not merely when a prompt is long.
A skill should make selection safer. If its description is vague or overlaps heavily with other skills, the agent may invoke it for the wrong job and follow a detailed process that never fit the task.
How to evaluate it
Example decision
Package a release-note workflow with a trigger for completed releases, steps for reading merged changes, a rule against inventing impact, and a checklist that compares the draft with the actual diff and issue links.
