Thesis

Codex CLI is the open shell around OpenAI's coding agent. The listing splits the license: MIT/Apache at the CLI, commercial-usage at the hosted runtime. Skills resolve against the same SKILL.md graph as Claude Code.

Operators use Codex CLI when they want an open control plane and a closed model. The 8 KB skill-cap is real — large Skills must be split. The hosted runtime is the billable object on Harnessmarket; the CLI is a free artifact with a signed SBOM.
