Streamlit agent skill

Install

streamlit skills --yes

This is third-party code. Review the repository files before installing.

What it does

The developing-with-streamlit skill ships with the streamlit pip package and matches the installed version. It is a router: depending on the task it points the agent to references on building apps, session state, caching and fragments, themes and widget styling, chat UIs for assistants and custom components with st.components.v2. It also covers server setup through st.App with ASGI, Starlette and FastAPI and debugging common errors. The streamlit skills command places the skill into agent folders in the project or installs a global version.

Who it is for. For analysts and Python developers building dashboards and internal tools on Streamlit with an agent.

Example request

Build a Streamlit sales dashboard from sales.csv with a region filter and cached loading

Limitations

Requires a Streamlit version that includes the streamlit skills command. Project install symlinks to the package, while global install fetches the meta skill from GitHub. The separate streamlit/agent-skills repository is archived.

How to disable. Remove the developing-with-streamlit folder from the project's .claude/skills and .agents/skills or from the global skills directory.

Security check

• The skill consists of instructions and references

README in short

Streamlit is a Python framework for quick data apps and dashboards. The agent skill lives in the package under lib/streamlit/.agents, and the streamlit skills command installs it interactively or with --yes and --global. When an app runs locally, Streamlit suggests this command if it detects an agent without the skill. The other skills in .claude/skills serve Streamlit's own maintainers. Apache 2.0 licensed.
