Collaborative design and specification workflow for turning ideas into detailed, implementation-ready designs. Use for feasibility checks ("is X possible?", "can we do Y?"), design exploration, and full specification. Triggers on "let's build", "I want to add", "how should we", "is it possible", "what would it take", "design", "architect", "spec out", or any non-trivial feature request. Skip ONLY for trivial single-location changes (typo, rename, color change).

Execute implementation specs autonomously. Takes an impl-spec file, creates a topic branch, spawns implementation subagents per phase, runs reviewers at checkpoints. Surfaces to user only when issues can't be auto-resolved.

Generate implementation specs from design specs. Takes a design spec file and produces a detailed, phased task breakdown ready for autonomous execution. Use after brainstorming is complete and design spec is written. Invoke with the design spec file path as argument.
