Part 3 of 4 (plan: ~/.claude/plans/system-instruction-you-are-working-polymorphic-twilight.md).
Gate-tier (E1, free, runs on every `bun test`):
test/preamble-compose.test.ts — pins the composition order
Asserts AskUserQuestion Format section renders BEFORE Model-Specific
Behavioral Patch in tier-≥2 preamble output. Covers claude default,
opus-4-7 overlay, tier 2/3, and codex host. Catches any future edit
to scripts/resolvers/preamble.ts that silently reverts the order.
test/resolver-ask-user-format.test.ts — pins the Pros/Cons contract
14 assertions against generateAskUserFormat output: D<N>, ELI10,
Stakes if we pick wrong:, Recommendation: <choice>, Pros / cons:,
✅/❌ markers, min 2 pros + 1 con rules, hard-stop escape exact
phrase, neutral-posture CT1 rule ((recommended) label preserved for
AUTO_DECIDE), Completeness coverage-vs-kind, tool_use mandate
(rule 11), self-check list, D-numbering model-level caveat.
test/model-overlay-opus-4-7.test.ts — pins the pacing directive
Asserts raw overlay file + resolved overlay output contain "Pace
questions to the skill" and NOT "Batch your questions". Verifies
INHERIT:claude chain still works (Todo-list, subordination wrapper),
Fan out / Effort-match / Literal interpretation nudges preserved.
Also asserts claude base overlay does NOT carry the Opus-specific
pacing directive (no cross-contamination).
Periodic-tier (E2, Opus-dependent, ~$1-2/run):
test/skill-e2e-plan-prosons.test.ts — 4 cases extending v1.6.3.0 harness
1. Format positive — every token present when plan has real tradeoff
2. Hard-stop NEGATIVE — plan with genuine tradeoff must NOT dodge to
"No cons — hard-stop choice" escape
3. Neutral-posture NEGATIVE — plan where one option dominates must emit
(recommended) label + "because <reason>", must NOT dodge to
"taste call" / "no preference"
4. Hard-stop POSITIVE — destructive-action plan may legitimately use
the hard-stop escape
test/helpers/touchfiles.ts — entries for all new eval cases
Dependencies: overlay, preamble.ts, generate-ask-user-format.ts, and
the 4 plan-review templates. Diff-based selection triggers the evals
whenever those files change. Also added entries for 7 expanded-coverage
cases (ship, office-hours, investigate, qa, review, design-review,
document-release) — test cases will land in follow-up PRs per skill.
Follow-ups noted in test file header:
- True multi-turn cadence eval (3 findings → 3 distinct asks) — current
harness captures one $OUT_FILE per session; multi-turn capture needs
new harness support.
- Expanded-coverage test cases for the 7 non-plan-review skills.
Verified:
- bun test: 349 pass (30 new + 319 baseline), 1 pre-existing security-bench
oversize failure on main (unrelated, unchanged).
