What problem does it solve? Ideas and proposals often go straight from a quick brainstorm to implementation without critical review, leaving hidden risks, unchallenged assumptions, and unanswered questions that surface too late. This Skill structures deep investigation into a repeatable multi-phase workflow with saved, auditable outputs. ## Core Features & Use Cases - Three investigation modes: Explore (brainstorm only), Challenge (brainstorm plus critical scrutiny, the default), and Resolve (full pipeline with solution assessment). - Agent-orchestrated review: Summons a scrutiny-agent for structured risk and assumption analysis, and a solution-assessor for effort, risk, and viability evaluation of candidate fixes. - Persistent outputs: Saves amended brainstorm documents with a Deep Dive Synthesis section into project documentation directories, co-locating scrutiny and solution-assessment files. - Use Case: Before committing a new feature to the sprint board, run a deep dive to brainstorm the design, have the scrutiny agent flag medium and high severity risks, assess concrete solutions, then convert the refined output into Epics and Stories. ## Quick Start Ask the agent to deep dive on your feature idea and choose the challenge mode to get a brainstorm with critical scrutiny and a saved synthesis document.
