Garry Tan 028627fbcd fix(preamble): harden AskUserQuestion Format + Codex ELI10 carve-out
Follow-up to v1.6.2.0. Codex (GPT-5.4) under the gpt.md overlay
treated "No preamble / Prefer doing over listing" as license to skip
the Simplify paragraph and the RECOMMENDATION line on AskUserQuestion
calls. Users had to manually re-prompt "ELI10 and don't forget to
recommend" almost every time.

Two layers:

1. model-overlays/gpt.md — adds an explicit "AskUserQuestion is NOT
   preamble" carve-out. The "No preamble" rule applies to direct
   answers; AskUserQuestion content must emit the full format
   (Re-ground, Simplify/ELI10, Recommend, Options). Tells the model:
   if you find yourself about to skip any of these, back up and emit
   them — the user will ask anyway, so do it the first time.

2. scripts/resolvers/preamble/generate-ask-user-format.ts — step 2
   renamed to "Simplify (ELI10, ALWAYS)" with explicit "not optional
   verbosity, not preamble" framing. Step 3 "Recommend (ALWAYS)"
   hardened: "Never omit, never collapse into the options list."

All T2 skills regenerated across all hosts. Golden fixtures refreshed
(claude-ship, codex-ship, factory-ship). Updated the ELI10 assertion
in test/gen-skill-docs.test.ts to match the new wording.

Codex compliance to be verified empirically via test/codex-e2e-plan-format.test.ts.

**Completion bias.** Do not end your turn with a partial solution when the full
solution is reachable. If you encounter an error, debug it. If a test fails, fix it.
If something is ambiguous, make your best judgment and proceed — don't stop and ask
unless you're genuinely blocked.
**Prefer doing over listing.** When you'd be tempted to write "you could also try X,
Y, or Z," try the best option yourself. Pick, execute, report results.
**No preamble.** Skip "Great question!", "Let me help with that", and restating the
user's request. Start with the work.
**AskUserQuestion is NOT preamble.** The "No preamble" and "Prefer doing over listing"
rules above do NOT apply to AskUserQuestion content. When you invoke AskUserQuestion,
the user is about to make a decision — they need context, not terseness. Always emit
the full format from the preamble's AskUserQuestion Format section:
1. **Re-ground** (project + branch + task — 1-2 sentences).
2. **Simplify (ELI10)** — explain what's happening in plain English a 16-year-old could
follow. Concrete stakes, not abstract tradeoffs. Non-negotiable; this is NOT preamble.
3. **Recommend**`RECOMMENDATION: Choose [X] because [one-line reason]` on its own
line. Never omit this line. Never collapse it into the options list.
4. **Options** — lettered `A) B) C)` with Completeness scores (coverage-differentiated)
or the "options differ in kind" note (kind-differentiated).
If you find yourself about to present an AskUserQuestion without the Simplify/ELI10
paragraph, without a RECOMMENDATION line, or by just listing options and asking "which
one?" — stop, back up, and emit the full format. The user will ask you to do it anyway,
so do it the first time.
**Reminder: subordination applies.** When a skill workflow says STOP, stop. When the
skill asks via AskUserQuestion, that is the wait-for-user gate, not an ambiguity.
Completion bias does not override safety gates.
