This directory holds Codex skills—self-contained folders (each with a SKILL.md and optional helpers) that extend the agent's abilities.

Included skills:

• codex-app-modifier: creates locally modified Codex macOS app bundles with icon replacement, signing, launch, and verification.
• codex-changelog: checks the installed Codex CLI version and fetches the matching GitHub Releases changelog.
• hig-docs: answers Apple Human Interface Guidelines questions using bundled HIG markdown references.
• learn: captures user corrections/preferences during a session and writes durable notes to AGENTS.md so future turns follow them.
• revise-instructions: edits existing prompts, skills, and instruction files by removing contradictions first and revising in place.
