What problem does it solve? Teams often jump into implementation before fully understanding a problem, leading to rework and misaligned requirements. This Skill provides a dedicated thinking mode where you can investigate the codebase, compare approaches, and crystallize decisions before committing to a change. ## Core Features & Use Cases - Codebase-grounded exploration: Reads existing architecture, integration points, and patterns to ground discussions in reality rather than theory. - Visual thinking: Produces ASCII diagrams, state machines, comparison tables, and architecture sketches to clarify complex problems. - OpenSpec integration: Detects active changes via the openspec CLI, reads existing proposals and designs, and offers to capture decisions into specs, design.md, tasks.md, or proposal.md. - Use Case: Before adding real-time collaboration to your app, enter explore mode to map the collaboration spectrum (presence, cursors, CRDTs), weigh tradeoffs, and then formalize the chosen direction as an OpenSpec change proposal. ## Quick Start Ask the assistant to enter explore mode to think through your idea or investigate a problem before creating a change proposal.
