start

start is a command for coding agents from app-builders-club/design-builder. It costs 14 tokens per session (214 once invoked), scanned A, original, MIT.

An alias for the design-builder setup command that establishes a project's design foundation. It starts the same setup process under a shorter, familiar command name.

In plain words
What is it for?
Use it when beginning a design-builder project and establishing its initial design direction and project context.
Why use it?
It lets developers begin a new design project using either the setup command or this start alias. The alias preserves compatibility with the historical command name.

Command

Part of the design-builder plugin — 9 skills, 7 commands, 1 agent, 2 MCP servers shipped together

Install

Getting it into your agent

One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

agentmods
npx agentmods add commands/app-builders-club/design-builder/start
Clone the repo
git clone --depth 1 https://github.com/app-builders-club/design-builder

Or install design-builder, the plugin that ships this one along with the rest of its 9 skills, 7 commands, 1 agent, 2 MCP servers.

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

start 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 5d 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

/design-builder:start — alias for /setup

You were invoked as /design-builder:start. This is the same command as /design-builder:setup — historically start is the more familiar name for "begin a new project".

Execute the full body of commands/setup.md — do not redirect, do not ask the user to invoke a different command. Read commands/setup.md once and follow it end-to-end.

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.
