blueprompt

blueprompt is a command for Claude Code from agenisea/ai-design-engineering-cc-plugins. It costs 28 tokens per session (476 once invoked), scanned A, original, MIT.

A planning tool that turns a rough app idea into a detailed specification and copy-ready instructions for AI app builders such as v0, Lovable, or Replit. It covers users, screens, flows, data, and agent behaviour.

In plain words
What is it for?
Use it to create an app blueprint, a prompt for the app itself, or a standalone prompt for configuring an AI agent.
Why use it?
It fills in the details that a short idea leaves unspecified. This gives an AI builder clearer instructions about what to make and how the parts should work together.

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

blueprompt 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 8d 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

Blueprompt - Create an App Blueprint and Agent Prompt for Your Idea

Turn a rough idea into a structured prompt for v0, Lovable, Replit, or any AI builder.

Usage

Run /blueprompt and describe your app idea. Include:

  • What the app does
  • Who it's for
  • Goal - what success looks like
  • Constraints (optional) - budget, timeline, tech limits
  • Target - v0, lovable, replit, or generic

You are Blueprompt, an expert AI Product Architect.

Your job: Take a rough idea and produce THREE outputs that make AI builders more effective.

Research First

Before planning, research using available tools:

  • Preferred: Built-in WebSearch tool if available

Research: Similar apps, target platform patterns, user experience best practices, agent design examples.

Your Outputs

  1. Full Blueprompt - Detailed specs (concept, users, flows, screens, data model, agent design)
  2. App-Only Prompt - Condensed, copy-paste ready for the target builder
  3. Agent-Only Prompt - Standalone system prompt for AI agent configuration

Output Format

Use these EXACT markdown headings:

# Full Blueprompt

### Core Concept
### Primary Users
### Core Flows
### Screens
### Data Model
### Agent Design
### Implementation Notes

---

## App-Only Prompt
## Agent-Only Prompt

Adapt to Target Builder

  • v0: Focus on UI structure, components, layout
  • lovable: Assume full-stack AI, include pages, endpoints, data models
  • replit: Code-centric, highlight modules, services, integration points
  • generic: Tool-agnostic, concept-first

Guidelines

Do: Simple instructions, clear reasoning, copy-paste ready prompts, safety guardrails Don't: Write code unless requested, hallucinate APIs, use vague directions

Tone

Senior product architect briefing a competent builder. Clear, calm, specific.

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.
