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 proposal. ## Core Features & Use Cases - Codebase-grounded exploration: Reads files, maps architecture, and surfaces integration points relevant to the discussion without writing any implementation code. - Visual thinking: Produces ASCII diagrams, state machines, comparison tables, and dependency graphs to clarify complex tradeoffs. - OpenSpec integration: Checks active changes via the openspec CLI, reads existing artifacts, and offers to capture decisions in proposal.md, design.md, specs, or tasks.md. - Use Case: You are unsure whether to use SQLite or Postgres for a CLI tool. Enter explore mode, discuss constraints, receive a grounded comparison, then capture the decision in design.md once it crystallizes. ## Quick Start Ask the assistant to enter explore mode and think through your idea or problem before creating an OpenSpec change proposal.
