Conciseness

The body is ~50 lines of dense operational rules — selection preferences, routing, one command, output and deletion policy — with no concept explanations and no padding. Every sentence instructs rather than explains, matching the 'lean and efficient; every token earns its place' anchor.

Actionability

The cleanup command is concrete and executable ('node "<skill-dir>/scripts/strip-transcript.mjs" "<subtitle-file>" > "<run-dir>/transcript.txt"') with explained flags whose behavior was verified against the actual script, and routing conditions are specific and testable. Placeholders are explicitly defined ('Use its absolute path as <run-dir>'), so the guidance is copy-paste ready rather than pseudocode.

Workflow Clarity

The sequence is explicit with branching (URL returns subtitles → clean; returns media → go directly to recognition) and includes validation checkpoints: 'Check command errors and confirm this run produced a transcript containing text. Report empty results rather than claiming success', plus a stop-and-report error policy. Because validation precedes the destructive cleanup-deletion step and playlist/batch handling is addressed, the destructive/batch cap does not apply.

Progressive Disclosure

SKILL.md is a clear overview that routes to one-level-deep, well-signaled references ([URL transcripts](references/url.md), [Local transcripts](references/local.md#speech-recognition)) that exist on disk with matching headings, plus a bundled script. Content is appropriately split with nothing inlined that belongs in a reference.

Specificity

"Extract transcripts from URLs or local video/audio files" names the domain and one concrete action (extracting transcripts) across two input types, but does not enumerate the skill's other operations such as subtitle cleanup or speech recognition. It sits at the 'names domain and 1-2 concrete actions' anchor, not score 4, because there is no list of several distinct actions.

Completeness

It explicitly answers both parts: what ("Extract transcripts from URLs or local video/audio files") and when ("Use when the user asks for a transcript, subtitles, or to transcribe media") with concrete trigger phrases. This directly matches the score-5 anchor; the 'when' clause is explicit, not implied, ruling out score 4.

Trigger Term Quality

The description includes the natural phrases users would say — "transcript", "subtitles", "to transcribe media" — giving good synonym coverage. It falls short of score 5 because common variations like "captions" and file extensions (.srt, .vtt) are missing.

Distinctiveness Conflict Risk

Transcription of media is a clear niche with mostly distinct triggers, but the trigger term "subtitles" could also fire for requests to download or edit subtitle files, a closely related skill. Minor overlap risk places it at the 'mostly distinct' anchor rather than the minimal-conflict score 5.
