What problem does it solve? Half-formed plans and design ideas live in conversation and die with the context window. This Skill runs a relentless, research-backed interview that pulls the full concept out of your head, verifies every claim against real machines and current sources, and writes everything to durable files on disk that survive context loss and resume across sessions. ## Core Features & Use Cases - Depth-first decision tree interview: Walks a branch menu of your design with no question cap, forcing vague answers into concrete decisions, with every option showing where it lands, what it forecloses, and what being wrong costs. - Ground-truth verification: Checks the actual machines, run outputs, and test artifacts before asking, never claims something is absent without verifying it, and dispatches background research against a global deduplicated ledger so nothing is checked twice. - Durable session files: Appends every exchange verbatim to grill.md, then converts at session end into CONCEPT.md, STATE.md, dormant branch summaries, and a research index so any fresh session can resume exactly where you stopped. - Use Case: You have a fuzzy idea for a retrieval system. Say "grill me" and the Skill maps your repo and machines, offers a branch menu (data model, retrieval strategy, eval methodology), interrogates each branch depth-first, verifies library claims in the background, and leaves a complete decision record on disk without writing a line of implementation code. ## Quick Start Say "grill me on my retrieval system design" to start a structured interview that extracts your plan into resumable files on disk.
