Skill profile
migrate-to-codex
Migrates instruction files, skills, agents, and MCP config from another agent into Codex's own files, without touching the source agent's files.
What it actually does
- Migrates instruction files, skills, agents, and MCP config from another agent into Codex's own files (`AGENTS.md`, `.codex/`, `.agents/`, `~/.codex/`) once you've picked a target.
When to use it — and when not to
Use it when
- You're moving a project from another agent — Claude Code in particular — into Codex and want the switching cost handled for you.
Not for
- You want to keep the source agent's setup intact for later — it's careful not to touch the source agent's files, but confirm that's still the behavior you expect before running it.
Agent compatibility
- Codex
Confirmed means the skill’s own source or vendor states it works with that agent. Portable means it only reaches that agent through the shared SKILL.md format and a directory convention — real, but a weaker claim. An agent with no entry here isn’t known to be unsupported; it simply isn’t documented either way, so nothing is claimed. Full model on Agent Skills Compatibility.
Requirements and operational surface
What it actually does at runtime
- Writes to Codex config paths (`AGENTS.md`, `.codex/`, `.agents/`, `~/.codex/`)
- Does not modify the source agent's files or unrelated config, per its own instructions
Evidence and provenance
