Claude Plugin: Spec-Driven Development

Architecture Decisions

Record decisions using the MADR format with structured sections for context, options, consequences, and Mermaid diagrams. Every choice gets the rationale it deserves.

OpenSpec Specifications

Formal requirements with RFC 2119 keywords and WHEN/THEN scenarios. Paired spec + design documents separate the "what" from the "how" so each can evolve independently.

Sprint Planning

Break specifications into actionable sprint issues. Supports Beads, GitHub, GitLab, Gitea, Jira, and Linear so your architecture flows straight into your tracker.

Drift Detection

Quick-check files against specs or run a full audit across the project. Catch when code drifts from decisions before it becomes technical debt.
