Original instructions from the publisher’s SKILL.md

# Developing with Streamlit

Streamlit (>=1.57) ships detailed reference documentation for building Streamlit apps inside its pip package. The bundled skill is a routing `SKILL.md` plus a `references/` folder of topic-specific reference docs (dashboards, themes, layouts, session state, custom components, etc.).

## Usage

Run the discovery script with the user's project directory:

```bash
python <SKILL_DIR>/scripts/discover.py --project-dir <USER_PROJECT_DIR>
```

The script prints either:

- **A path on stdout** (exit 0) — the bundled `SKILL.md`. Read it; it points into `references/`.
- **An `ERROR:` block on stderr** (non-zero exit). Follow the printed instructions and re-run.

`<SKILL_DIR>` is the directory containing this file; `<USER_PROJECT_DIR>` is the absolute path to the user's project. Passing `--project-dir` matters because the script resolves `.venv`, `../.venv`, `Pipfile`, `poetry.lock`, `pdm.lock`, and `uv.lock` relative to it.
