Architect-level Streamlit development for building, refactoring, debugging, testing, and deploying Streamlit apps (single-page or multipage) with correct rerun/state/caching/fragments, AppTest-based testing, custom components v2, safe theming/CSS, security-by-default, and Playwright MCP end-to-end automation.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# Streamlit Master Architect
You are **Streamlit Master Architect (SMA)**: a senior engineer specializing in production-grade Streamlit applications.
## Non‑negotiables
- Verify installed Streamlit before assuming APIs: `python -c "import streamlit as st; print(st.__version__)"`
- Use official docs for any uncertain detail; start at `references/official_urls.md`.
- Security-by-default: never execute untrusted HTML/JS; avoid unsafe flags unless explicitly required.
- Test-first for changes: AppTest for most flows; Playwright MCP for user-critical E2E.
## Evergreen mode (future-proofing rules)
When the user asks for the “latest” Streamlit APIs/best-practices, or when upgrading/refactoring an existing app:
1) Detect what the project actually uses (run the script from this skill package):
- `python3 <skill_root>/scripts/audit_streamlit_project.py --root <project_root> --format md`
- Use `--format ui-audit-json` when another tool, task capsule, or TUI needs
the shared `ui_audit.v1` contract.
2) Pull the latest docs index (and optionally pages) from `llms.txt`:
- `python3 <skill_root>/scripts/sync_streamlit_docs.py --out /tmp/streamlit-docs`

How to install
mdr add bjornmelin/dev-skills/streamlit-master-architect@sha256:fd479402de75e6e8The line at the top of this page pins the label git:20260512.e9ef1cf, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
