**Summary**
- Adds the public `migrate-to-codex` curated skill for migrating
external agent setup into Codex-facing files.
- Includes the approved skill instructions, references, and migration
scripts from openai/skills-internal#84.
- Places the skill at `skills/.curated/migrate-to-codex`, which is the
installable public path the Codex App should reference.
**Summary**
- Adds curated `$cli-creator` skill for building composable CLIs Codex
can run from any repo.
- Defines the command contract: PATH install, `doctor`, bounded JSON,
discovery/resolve/read/write commands, raw request fallback, and
auth/config handling.
- Adds runtime guidance, reference patterns, and the companion-skill
handoff with `$skill-creator`.
