Dense and mostly on-task, but several multi-paragraph rationale blocks (the retranscribe legacy explanation, '为什么必须有词典', '字幕存自己的文字是故意的') teach reasoning Claude could partly infer, fitting 'mostly efficient but includes some unnecessary explanation' rather than the lean score 3.

Provides fully executable bash throughout — the plugin-list node one-liner, transcript dictionary/align/correct, subtitle build, and open commands — with concrete argument forms and the corrections JSON shape, matching copy-paste-ready guidance.

Sequences sections 0–5 with explicit validation checkpoints and feedback loops (missing→auto-resume, needsAttention reporting, the --replace confirmation gate, failure-recovery table), satisfying the batch/destructive feedback-loop requirement rather than leaving checkpoints implicit.

Offloads detail to one-level-deep, clearly signaled references (subtitle-correction.md verified present; 校对规则/词典/runtime 契约 linked by labeled markdown links) instead of inlining it, with no nested-reference chains.

Lists multiple concrete actions (compute cut time from transcript+ledger, rewrite proper nouns via dictionary and author script, sentence-based splitting, per-screen review in Studio), matching the 'multiple specific concrete actions' anchor rather than the partial-coverage score 2.

Explicitly answers both what ('给剪好的口播做字幕…逐屏复核') and when ('用户说…时使用'), with an explicit Use-when-style trigger clause, so it is not capped at 2.

Provides natural user phrasings — '做字幕、加字幕、改字幕、重新分屏、字幕不对' — that a user would actually say, giving good coverage rather than just 'some relevant keywords'.

Carves a clear niche (subtitles for already-cut talking-head) and adds explicit negative boundaries ('不要用于删词剪辑、物理剪切、分镜动画或成片渲染'), making conflicts with sibling skills unlikely.
