CLI-Anything for Codex
Use this skill when the user wants Codex to act like the CLI-Anything builder.
If this skill is being used from inside the CLI-Anything repository, read ../cli-anything-plugin/HARNESS.md before implementation. That file is the full methodology source of truth. If it is not available, follow the condensed rules below.
Inputs
Accept either:
- A local source path such as
./gimpor/path/to/software - A GitHub repository URL
Derive the software name from the local directory name after cloning if needed.
Modes
Build
Use when the user wants a new harness.
Produce this structure:
<software>/
└── agent-harness/
├── <SOFTWARE>.md
├── setup.py
└── cli_anything/
└── <software>/
├── README.md
├── __init__.py
├── __main__.py
├── <software>_cli.py
├── core/
├── utils/
└── tests/
Implement a stateful Click CLI with:
- one-shot subcommands
- REPL mode as the default when no subcommand is given
--jsonmachine-readable output- session state with undo/redo where the target software supports it
