Blueprint — Construction Plan Generator

Turn a one-line objective into a step-by-step plan any coding agent can execute cold.

Overview

Blueprint is for multi-session, multi-agent engineering projects where each step must be independently executable by a fresh agent that has never seen the conversation history. Install it once, invoke it with /blueprint <project> <objective>.

When to Use This Skill

• Use when the task requires multiple PRs or sessions
• Use when multiple agents or team members need to share execution
• Use when you want adversarial review of the plan before execution
• Use when parallel step detection and dependency graphs matter

How It Works

1. Research — Scans the codebase, reads project memory, runs pre-flight checks
2. Design — Breaks the objective into one-PR-sized steps, identifies parallelism, assigns model tiers
3. Draft — Generates the plan from a structured template with branch workflow rules, CI policy, and rollback strategies inline
4. Review — Delegates adversarial review to a strongest-model sub-agent (falls back to default model if unavailable)
5. Register — Saves the plan and updates project memory

Examples

Example 1: Database migration

/blueprint myapp "migrate database to PostgreSQL"

Example 2: Plugin extraction

/blueprint antbot "extract providers into plugins"
