Turn an intent into one **grounded, cited, build-ready ADR**, then hand it to `nightshift:plan`'s landing step. This collapses `brainstorm → spec → writing-plans → nightshift` into **`adr → nightshift`** for "I know what I want, build it" work.

Cross-provider adversarial review of a finalized plan, spec, design doc, ADR, or code diff using OpenAI Codex (GPT-5.6 Terra). AUTO-TRIGGER at plan gates — invoke immediately after any of: (1) a plan written by `nightshift:plan` is finalized, (2) an ADR draft is completed. AUTO-TRIGGER for code: after implementing a Codex-reviewed plan, run diff mode on the branch range before opening the PR — a reviewed plan is NOT a reviewed diff. Also invoke on request — "codex review this plan", "codex review this diff", "get a second opinion on this design", "terra review". Do NOT re-run on an artifact already reviewed without an explicit user ask; each chain burns paid quota.

A plan is the only thing Nightshift reads. What this skill produces is read at 2 a.m. by a generator that cannot ask anyone anything, so every task must be complete on its own, and every open question must be closed before the plan merges. Announce: "Using nightshift:plan to turn this into a landabl

The loop leaves its evidence in three places and remembers nothing else. Read all three before saying anything. Announce: "Using nightshift:morning to read last night's run."

A durable artifact has readers you will never meet, arriving with zero conversation context, often skimming, sometimes another agent. Write for that reader. This skill is a system to write toward, not a list of things to avoid: supply the right structure and the slop has nowhere to live.
