The rename from writing-great-skills moved agents/openai.yaml without
updating it. Codex filters a skill out of the model-visible skills list
when policy.allow_implicit_invocation is false, so the description could
not trigger the skill — only an explicit $writing-for-agents mention.
Drop the policy block (implicit invocation defaults to true) and correct
the stale display_name and short_description. Move the skill into the
Model-invoked list in both READMEs, where the frontmatter already put it.
