Planning and Blueprinting System

A minimal, enforceable system for doing planning, blueprinting, and specification inside a codebase using two core concepts: plans (proposals) and specs (contracts).

When to Apply

Use this skill when:

• Creating a proposal or blueprint for new work
• Documenting accepted specifications
• Doing architectural planning
• Tracking decision and implementation status
• Promoting a plan to a formal specification

Core Concepts

Plan — A proposal, blueprint, or work-in-progress design. Plans are iterative, may contain open questions, and are not authoritative contracts.

Spec — An accepted contract and source of truth. Specs define reference behavior that reviewers and tests enforce. They must remain accurate over time.
