scaffold-app

A setup procedure for creating a new Veryfront application with the expected project structure, configuration, and development conventions.

In plain words
What is it for?
Use it to initialize a Veryfront app, run its health checks, start the development server, and confirm that its MCP connection is available.
Why use it?
It reduces setup mistakes by discovering valid templates, checking the new project, and providing recovery steps when commands fail.

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.

Security

Grade A, and why

scaffold-app scanned grade A with 0 findings 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 2d 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.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

What it actually says

Scaffold App

Create a new Veryfront application with proper structure and conventions.

Steps

  1. Discover templates

    veryfront schema --json | jq '.commands[] | select(.name == "init")'
    
  2. Create project

    veryfront init <name> --template <template> --yes --json
    

    Expected: { "success": true, "command": "init", "data": { "projectDir": "..." } }

  3. Verify project health

    cd <name>
    veryfront doctor --json
    

    Expected: all checks pass

  4. Start dev server

    veryfront dev
    

    Verify MCP is available at the printed dev MCP URL. The default URL is http://localhost:3002/mcp.

Error Recovery

  • init fails: Check template name with veryfront schema --json, retry with --force
  • doctor fails: Read the check details, fix missing dependencies
  • dev fails: Run veryfront clean, then retry
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.
