Grill-Me-Codex — Get Grilled, Then Get Reviewed

Two acts, two different jobs:

• Act 1 fixes the #1 failure mode: building the wrong thing. Claude interrogates you until intent is locked — no guessing at ambiguity. (This act is Matt Pocock's grill-me, used under MIT — see THIRD-PARTY-NOTICES.md.)
• Act 2 fixes the #2 failure mode: a plan that sounds right but breaks. A different model (Codex) adversarially attacks the locked plan. Cross-model = no echo chamber.

You enter at two points only: answering the grill, and signing off the converged plan. Codex is read-only the whole time and never touches a file.

ACT 1 — GRILL (you ↔ Claude)

Interview me relentlessly about every aspect of this plan until we reach a shared understanding. Walk down each branch of the design tree, resolving dependencies between decisions one-by-one. For each question, provide your recommended answer.

Ask the questions one at a time, waiting for my answer before continuing.

If a question can be answered by exploring the codebase, explore the codebase instead.
