What is databricks-app-apx?

A skill for building full-stack Databricks applications with APX, using FastAPI for the backend and React for the web interface.

Use it to initialize or develop a Databricks app, add backend routes and models, and build its React interface when APX is the chosen framework.

It provides a defined setup and development path for APX projects, including checks for required tools and project configuration.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Model	Per session	Once invoked
Fable 5.1	$0.00024	$0.01939
Opus 5.5	$0.00010	$0.00776
Sonnet 5.5	$0.00005	$0.00388
Haiku 4.5	$0.00002	$0.00194

Security

Grade A, and why

databricks-app-apx scanned grade A with 1 finding against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 1mo ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Databricks APX Application

Build full-stack Databricks applications using APX framework (FastAPI + React).

Trigger Conditions

Invoke when user requests:

"Databricks app" or "Databricks application"
Full-stack app for Databricks without specifying framework
Mentions APX framework

Do NOT invoke if user specifies: Streamlit, Dash, Node.js, Shiny, Gradio, Flask, or other frameworks.

Prerequisites Check

Option A) Repository configured for use with APX. 1.. Verify APX MCP available: mcp-cli tools | grep apx 2. Verify shadcn MCP available: mcp-cli tools | grep shadcn 3. Confirm APX project (check pyproject.toml)

Option B) Install APX

Verify uv available or prompt for install. On Mac, suggest: brew install uv.
Verify bun available or prompt for install. On Mac, suggest:

brew tap oven-sh/bun
brew install bun

Verify git available or prompt for install.
Run APX setup commands:

uvx --from git+https://github.com/databricks-solutions/apx.git apx init

Workflow Overview

Total time: 55-70 minutes

Initialize (5 min) - Start servers, create todos
Backend (15-20 min) - Models + routes with mock data
Frontend (20-25 min) - Components + pages
Test (5-10 min) - Type check + manual verification
Document (10 min) - README + code structure guide

Phase 1: Initialize

# Start APX development server
mcp-cli call apx/start '{}'
mcp-cli call apx/status '{}'

Create TodoWrite with tasks:

Start servers ✓
Design models
Create API routes
Add UI components
Create pages
Test & document

Phase 2: Backend Development

Create Pydantic Models

In src/{app_name}/backend/models.py:

Follow 3-model pattern:

EntityIn - Input validation
EntityOut - Complete output with computed fields
EntityListOut - Performance-optimized summary

See backend-patterns.md for complete code templates.

Create API Routes

In src/{app_name}/backend/router.py:

What ships with it

3 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.

Changes

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
