 - **[llm-cmd](https://github.com/simonw/llm-cmd)** accepts a prompt for a shell command, runs that prompt and populates the result in your shell so you can review it, edit it and then hit `<enter>` to execute or `ctrl+c` to cancel.
+- **[llm-cmd-comp](https://github.com/CGamesPlay/llm-cmd-comp)** provides a key binding for your shell that will launch a chat to build the command. When ready, hit `<enter>` and it will go right back into your shell command line, so you can run it.
 - **[llm-python](https://github.com/simonw/llm-python)** adds a `llm python` command for running a Python interpreter in the same virtual environment as LLM. This is useful for debugging, and also provides a convenient way to interact with the LLM {ref}`python-api` if you installed LLM using Homebrew or `pipx`.
 - **[llm-cluster](https://github.com/simonw/llm-cluster)** adds a `llm cluster` command for calculating clusters for a collection of embeddings. Calculated clusters can then be passed to a Large Language Model to generate a summary description.
 - **[llm-jq](https://github.com/simonw/llm-jq)** lets you pipe in JSON data and a prompt describing a `jq` program, then executes the generated program against the JSON.
