Blueprint Creator

Create exhaustive BLUEPRINT.md files by expanding a SPEC.md into maximum implementation detail. The SPEC defines the contract. The Blueprint fills every corner of that contract so an AI agent can translate it directly into code without a single judgment call.

Pipeline position: SPEC.md → BLUEPRINT.md → Code

Prerequisite: SPEC.md Must Exist

Before doing anything else, verify that a SPEC.md exists. Check in this order:

1. File in working directory: Look for SPEC.md (or similar: spec.md, SPEC_*.md) in the current project directory or /mnt/user-data/uploads/.
2. Provided in chat: Check if the user pasted or attached spec content in this conversation.
3. Referenced by name: Check if the user mentioned a spec they created previously.

If SPEC.md is found: Acknowledge it, summarize its scope in 2-3 sentences, and proceed to Phase 1.
