What it does

Build App is an agent skill from databricks-solutions/databricks-apps-cookbook. Build Databricks Apps from this cookbook: minimum folder layout and app.yaml per framework (Dash, Streamlit, Reflex, FastAPI), multi-page wiring, docs category-first workflow then README recipes, runtime rules, combining recipes. Feature code only from repo samples and docs/docs/.mdx. After the app runs, follow [productionize-app-dab](../productionize-app-dab/SKILL.md) for Databricks Asset Bundles (DABs). Do not use for AppKit, Genie App Builder, apx, AI/BI dashboards, or coding-agent MCP config — see When not to…

Its SKILL.md is about 3.4k 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 Backend & APIs, covering Backend development and Markdown. It works with Databricks, FastAPI, Model Context Protocol and Streamlit. The repository describes itself as: Ready-to-use code snippets for building interactive Databricks Apps.

What it can do on your machine

Read from SKILL.md and the folder at commit 4018368. 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:
- databricks
- bundle
From the folder's file list and the shell code blocks in SKILL.md.
Network
Links to these hosts (documentation or services it may open):
- docs.databricks.com
- github.com
- apps-cookbook.dev
From URLs in SKILL.md, links to its own repository left out.
Credentials
Names these keys or tokens, usually read from environment variables:
- DATABRICKS_CLIENT_SECRET
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

Build App loads about 3.4k tokens when it runs. Until then it costs about 137 tokens; SKILL.md has 1,142 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it: ~137
When it runs · the whole SKILL.md, loaded when a task matches: ~3.4k

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.

SKILL.md

Its licence (Custom licence) doesn't allow us to republish the file, so here is its outline and opening line. It has 1,142 words (~3,443 tokens).

“Stop and point the user at the other product. Do not scaffold Dash/Streamlit/Reflex/FastAPI from this cookbook.”
