Adds a per-model behavioral patch layer orthogonal to the host axis.
Different LLMs have different tendencies (GPT won't stop, Gemini
over-explains, o-series wants structured output). Overlays nudge each
model toward better defaults for gstack workflows.
Codex review caught three landmines the prior reviews missed:
1. Host != model — Claude Code can run any Claude model, Codex runs
GPT/o-series, Cursor fronts multiple providers. Auto-detecting from
host would lie. Dropped auto-detect. --model is explicit (default
claude). Missing overlay file → empty string (graceful).
2. Import cycle — putting Model in resolvers/types.ts would cycle
through hosts/index. Created neutral scripts/models.ts instead.
3. "Final say" is dangerous — overlay at the end of preamble could
override STOP points, AskUserQuestion gates, /ship review gates.
Placed overlay after spawned-session-check but before voice + tier
sections. Wrapper heading adds explicit subordination language on
every overlay: "subordinate to skill workflow, STOP points,
AskUserQuestion gates, plan-mode safety, and /ship review gates."
Changes:
- scripts/models.ts: new neutral module. ALL_MODEL_NAMES, Model type,
resolveModel() for family heuristics (gpt-5.4-mini → gpt-5.4, o3 →
o-series, claude-opus-4-7 → claude), validateModel() helper.
- scripts/resolvers/types.ts: import Model, add ctx.model field.
- scripts/resolvers/model-overlay.ts: new resolver. Reads
model-overlays/{model}.md. Supports {{INHERIT:base}} directive at
top of file for concat (gpt-5.4 inherits gpt). Cycle guard.
- scripts/resolvers/index.ts: register MODEL_OVERLAY resolver.
- scripts/resolvers/preamble.ts: wire generateModelOverlay into
composition before voice. Print MODEL_OVERLAY: {model} in preamble
bash so users can see which overlay is active. Filter empty sections.
- scripts/gen-skill-docs.ts: parse --model CLI flag. Default claude.
Unknown model → throw with list of valid options.
- model-overlays/{claude,gpt,gpt-5.4,gemini,o-series}.md: behavioral
patches per model family. gpt-5.4.md uses {{INHERIT:gpt}} to extend
gpt.md without duplication.
- test/gen-skill-docs.test.ts: fix qa-only guardrail regex scope.
Was matching Edit/Glob/Grep anywhere after `allowed-tools:` in the
whole file. Now scoped to frontmatter only. Body prose (Claude
overlay references Edit as a tool) correctly no longer breaks it.
Verification:
- bun run gen:skill-docs --host all --dry-run → all fresh
- bun run gen:skill-docs --model gpt-5.4 → concat works, gpt.md +
gpt-5.4.md content appears in order
- bun run gen:skill-docs --model unknown → errors with valid list
- All generated skills contain MODEL_OVERLAY: claude in preamble
- Golden ship fixtures regenerated

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.
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.
