By a 12-year product manager who builds 0-to-1: takes a beginner from a vague idea to a buildable plan, then guides the build (GitHub basics, clean-code habits, a verify-and-iterate loop, a checkup for the mess). For Claude Code, Codex, and Antigravity. grill-me is for engineers, vibe-check is for everyone else.

Working-in-the-open canon for AI-assisted development. Constraints, decision rules, evidence standards, and ODD.

A product-engineering tool for detecting outcome drift across routes, tests, observability, and user-facing capabilities.
