Spec-Driven Development (SDD) harness & skill suite for Google Antigravity (AGY), Gemini 3.6, Claude Opus, DeepSeek R1, & Cursor/Windsurf agents.
This repository also configures its own agents. See what ag-sdd tells them →
Agent Claude Code
Specialized SDD Subagent for Phase 1 (Discovery) & Phase 2 (Spec Generation). Asks 3-5 sharp architectural questions using askquestion UI tool, drafts EARS requirements, creates Mermaid design diagrams, and generates uncapped A-C-E task lists.
Agent Claude Code
Specialized SDD Subagent for Phase 3 (Sequential Task Execution). Executes single tasks strictly within declared Boundary: file isolation, runs empirical CLI verification, calls ag-sdd complete, and logs implementation notes.
Agent Claude Code
Specialized SDD Subagent for Phase 4 (Quality Signoff). Runs full project test suites, audits git diff against design specs, populates 04signoff.md, and presents final quality assurance logs.
