Add Blueprint

[JuliusBrussee]

What is Blueprint?

Blueprint is a specification-driven development plugin for Claude Code by @JuliusBrussee.

It transforms natural language requirements into structured, numbered blueprints and then orchestrates automated parallel builds with validation and adversarial review — bridging the gap between high-level intent and production-ready code.

Key features

• Five-phase workflow — Research, Draft, Architect, Build, and Inspect phases via slash commands
• Blueprint-first approach — decomposes requirements into numbered, testable domain specs before any code is written
• Parallel execution — groups independent tasks and dispatches them concurrently across dependency tiers
• Dual-model adversarial review — integrates OpenAI Codex as a second reviewer to catch flaws single-model self-review misses
• Automated validation loops — each build task runs against acceptance criteria with fix-and-retry cycles
• Full traceability — every line of code traces back to a specific blueprint requirement
