What it does
Develop Wizard App is an agent skill from owid/etl. Create or modify Streamlit apps in the Wizard. Use when building new wizard apps, adding Streamlit pages, or working with apps/wizard/ code.
Its SKILL.md is about 720 tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.
It sits in Data & Analytics. It works with Streamlit. The repository describes itself as: A compute graph for loading and transforming OWID's data. The licence is MIT.
When your agent uses it
- Building new wizard apps
- Adding Streamlit pages
- Working with apps/wizard/ code
Example prompts
- “/develop-wizard-app”
Requirements
- Python 3
Workflow steps
2 steps, taken from the first numbered list in SKILL.md.
- Create apps/wizard/app_pages/your_app/app.py
- Register in apps/wizard/config/config.yml under a section's apps list
What it can do on your machine
Read from SKILL.md and the folder at commit 69ab20e. It shows what the files ask for, not the result of running them.
Tool permissions
Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.
From allowed-tools in the SKILL.md frontmatter.
Runs code
Shell commands in SKILL.md call:
make
From the folder's file list and the shell code blocks in SKILL.md.
Network
No URLs in SKILL.md.
From URLs in SKILL.md, links to its own repository left out.
Credentials
Names no API keys, tokens, secrets or passwords.
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.
Context cost
Develop Wizard App loads about 722 tokens when it runs. Until then it costs about 40 tokens; SKILL.md has 143 words of instructions outside code blocks.
Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.
Safety
Auto-check passed
The automated check found no risky patterns in SKILL.md.
Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

Streamlit Apps in Wizard
Apps live in apps/wizard/app_pages/. Run with make wizard or .venv/bin/etlwiz <alias>.
Creating a New App
- Create

import streamlit as st

def main():

Rules
st.set_page_config()must be the first Streamlit command- Use
@st_cache_datafor expensive operations - Use
url_persist()for shareable widget state - Material icons:
:material/icon_name:(Google Material Symbols) - HTTP requests: always
timeout=30and.raise_for_status() - Layout: use native
st.container(horizontal=True, vertical_alignment=..., horizontal_alignment=...)for rows,st.columns(..., border=True)for grids. No CSS/HTML hacks (st.markdown(..., unsafe_allow_html=True)with<style>) — they break silently across Streamlit versions. - Sections in
config.ymlneedtitle,descriptionandapps; the home page is generated from them (no images).
