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:

uv run 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.
