Thin entry-point skill — routes to the parent skill for full workflow.
This skill delegates to test-review for the underlying Codex MCP infrastructure. The generation-specific prompt template is at @skills/test-review/references/codex-prompt-test-gen.md.

This is the Generation variant — creates new unit tests for specified functions.
/codex-test-review)/codex-review-fast)/post-dev-test)First-principles UI/IA reasoning: turns a `<scenario>` + API field set into JTBD analysis, principle-anchored field-priority decisions, anti-pattern findings, and a bidirectional UI↔API gap report. Trigger: UI、UX、資訊架構、IA、scenario-driven UI、欄位優先級、information hierarchy. Not for: visual/CSS work (use `/frontend-design`), post-build critique (use `/critique`), or simplifying existing layouts (use `/distill`).
Necessity audit for over-designed spec elements. Use when: auditing lifecycle spec (1-requirements / 2-tech-spec / 3-architecture) for YAGNI/KISS violations, challenging necessity of FRs/NFRs/abstractions/configs via Codex adversarial debate. Not for: FP reasoning validity (use /codex-review-spec), completeness check (use /feature-completeness), detail review (use /codex-review-doc), or code-level simplification (use /simplify).
Sequential squash-merge of stacked PR chains into an epic branch. Handles dependency-ordered rebase, collision-safe backup tags, CI monitoring (delegates to /watch-ci), and post-merge verification. Use when: merging a chain of stacked PRs into an epic branch, collapsing a linear PR stack into per-PR squash commits, preparing an epic branch for final review. Triggers on: 'merge PRs into epic', 'squash chain', 'collapse PR stack', 'epic merge', or when user has a linear PR dependency chain (PR A -> B -> C) targeting an epic branch. Not for: single PR merge (use /create-pr + GitHub UI), simple rebase (use /smart-rebase), pre-merge analysis (use /merge-prep). Output: chain analysis table + backup tag manifest + per-iteration AskUserQuestion gate + verification log.
Push to remote and monitor CI. Validates branch safety, executes git push WITH explicit user approval, then monitors CI run status via gh CLI. Use when: user says 'push', 'push and watch CI', 'ship it', 'push-ci'. Not for: committing (use /smart-commit), creating PRs (use /create-pr), merging (use /merge-prep).
Post-development recap wrapper. Use when: AI/Codex just finished implementing a feature and the user wants a guided walkthrough with scope detection + doc generation + follow-up Q&A. Not for: generating only a doc (use /recap-doc), Q&A over an existing recap (use /recap-ask), technical share-out (use /tech-brief), first-principles reasoning of an existing doc (use /fp-brief), general code tracing (use /code-explore). Output: ScopeReport → briefing-recap-<date>.md → interactive Q&A session.
Interactive Q&A over an existing recap document. Use when: user wants to ask follow-up questions about a briefing-recap-<date>.md produced by /recap-doc, with recap-bounded context + out-of-scope redirect + optional promote-to-request. Not for: generating a new recap (use /recap-doc), general project Q&A (use /ask), code tracing (use /code-explore). Output: per-turn answer referencing file:line + end-of-session promote prompt.
