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, visualize architecture, and crystallize decisions before committing to a change proposal. ## Core Features & Use Cases - Codebase-grounded exploration: Reads existing code and OpenSpec artifacts to map architecture, find integration points, and surface hidden complexity. - Visual thinking: Produces ASCII diagrams, comparison tables, and state machines to clarify system behavior and tradeoffs. - OpenSpec integration: Checks active changes via the openspec CLI, reads existing proposals and specs, and offers to capture decisions into design.md, specs, or tasks.md. - Use Case: Before adding real-time collaboration to your app, use explore mode to map the current sync architecture, compare CRDT versus presence-based approaches, and capture the chosen design decision in a change proposal. ## Quick Start Ask the assistant to enter explore mode and think through whether Postgres or SQLite fits your CLI tool before writing any code.
