Individual skill
codex-cli
When handing work to the Codex CLI earns its cost, and how to size the run: second-model review, bounded implementation hand-offs, sandbox permissions, model and reasoning effort. Use when the user asks for Codex or `codex exec`, when a change is complex or high-stakes enough that an independent reviewer would change the outcome, or when a delegated run needs its model, effort, or permissions chosen. For agents other than Codex itself.

# Codex CLI
Codex is a second agent on the same machine, with its own model behind it.
That is the entire reason to reach for it: a model that did not write the code
has no memory of intending it to work. Everything below follows from that one
asymmetry — who wrote it, who reads it, and how much thinking each step is
worth paying for.
This skill is for the supervising agent, not for Codex. If you *are* Codex,
this does not apply — calling yourself buys nothing but a second opinion from
the same mind. Claude Code is the intended caller.
It also assumes the machine is already set up: `codex` on `PATH`, the user
logged in, and whatever MCP servers and tools they want available configured
