Codex-Cli-Captain publishes the `ccc` command. The command provides the local
CCC runtime, installer/check surfaces, and MCP stdio server used by the `$cap`
workflow in Codex CLI.
```sh
cargo install codex-cli-captain
ccc setup
ccc check-install
```
GitHub release assets and the existing `install.sh`/`install.ps1` flows remain
supported for operators who prefer packaged binaries.
