Bundled $skill-creator skill is missing from Codex Desktop

What version of the Codex App are you using (From “About Codex” dialog)?

Version 26.721.30844

What subscription do you have?

Pro

What platform is your computer?

Darwin 25.5.0 arm64 arm

What issue are you seeing?

The bundled $skill-creator skill is no longer available in Codex Desktop.

It does not appear in the current available-skills catalog, and no SKILL.md files are present under ~/.codex/skills/.system.

Older Codex sessions show that $skill-creator was previously available and was explicitly used for creating personal skills. The currently available $template-creator skill is not a replacement because it only creates Office artifact templates.

As a result, Codex cannot follow documented workflows that require $skill-creator to create or update a general-purpose skill.

What steps can reproduce the bug?

1. Open Codex Desktop.
2. Start a new task.
3. Ask Codex to use $skill-creator to create a personal skill.
4. Inspect the available-skills catalog.
5. Observe that $skill-creator is missing.
6. Inspect ~/.codex/skills/.system and observe that it contains no SKILL.md files.

Affected session ID:
019f91aa-d157-7672-b5f5-754ed66bb13a

What is the expected behavior?

$skill-creator should remain available as a bundled system skill and should be invokable from Codex Desktop.

If it has intentionally been replaced or removed, Codex should provide an equivalent general-purpose skill-creation workflow and clearly document the migration.

Additional information

This appears related to #20629 and #19265.

The failure is not limited to the skill picker: the agent's runtime-provided available-skills catalog also omits $skill-creator. Historical sessions still contain prompts and workflows that depend on it.
