SpecPilot is a Specification-Driven Development (SDD) tool that generates a complete .specs/ workspace of 12 engineering files (requirements, architecture, API specs, security threat models, roadmaps, tests, and more) plus agent-specific config files and slash commands for popular AI coding tools.
Use it at the start of a new project to establish AI alignment from session one, or when an existing AI-assisted project has grown complex and the AI agent is losing track of architecture, requirements, or standards. It's also valuable for teams wanting consistent spec initialization in scripts or CI setups.
