Spec-Driven Development: Specification Skill

Overview

Skill(foundry:foundry-spec) creates detailed JSON specifications before any code is written. It analyzes the codebase, designs a phased implementation approach, produces structured task hierarchies, and runs automatic quality checks including AI review.

Core capabilities:

• Analyze codebase structure using Explore agents and LSP
• Design phased implementation approaches
• Create JSON specifications with task hierarchies
• Define verification steps for each phase
• Automatic AI review of specifications
• Apply review feedback as modifications
• Validate and auto-fix specifications

Integrated Workflow

This skill follows a plan-first methodology. A markdown plan is MANDATORY before JSON spec creation, with human approval required after AI review.
