Conciseness

The body is lean, imperative, and free of padding — e.g. "A slide is never a bullet list, a status list, a table, or boxes with nothing connecting them" and "Drop each slide that does not change what the user knows". It explains nothing Claude already knows and every sentence instructs, matching anchor 5.

Actionability

Guidance is highly concrete with specific numeric rules ("Use at most 10 slides", "about ten words", "at least one second for each three words", "burn each subtitle into its slide's frames") and a concrete check method ("Look at one frame from each slide at chat size"). It falls short of anchor 5 because no render tool or command is ever named — "Render one silent landscape video, such as an mp4, with motion between slides" leaves the rendering mechanism entirely to inference.

Workflow Clarity

The workflow is clearly sequenced through ordered sections (plan slides → subtitle styling → render → check) with an explicit validation pass ("check the rendered file", "Measure each hold", "Count the words each slide adds against its measured hold") and a feedback loop ("Fix any slide you cannot read in that time, render again, and check again"). This is not a destructive or batch operation, so no cap applies, and it matches anchor 5.

Progressive Disclosure

The skill is under 50 lines, needs no external reference files, and is organized into clear sections (Slides, Subtitles, Render); its single reference to ../ketchup/SKILL.md is one level deep and clearly signaled. Per the simple-skill guideline this matches anchor 5.

Specificity

The description names several concrete outputs — "a short subtitled video of slides for what happened" and "the waiting calls as text under it" — which goes beyond naming the domain with 1-2 actions. It stops short of anchor 5 because it describes one composite deliverable rather than multiple comprehensive, separately enumerated actions.

Completeness

Both parts are present: a clear "what" (subtitled video of slides for what happened, waiting calls as text) and an explicit "when" ("Use for /ketchup-video"). It does not reach anchor 5 because the "when" is a single command mention without additional concrete trigger phrases, leaving it narrower than the anchor-5 pattern.

Trigger Term Quality

Relevant keywords like "Catch the user up", "video", "subtitled", and "slides" are present, but the only explicit trigger is the literal command "/ketchup-video", with no natural variations or synonyms a user might say (e.g. "recap video", "video summary", "catch-up video"). This matches anchor 3 (some relevant keywords, missing common variations) rather than 4, which requires broader natural-term coverage.

Distinctiveness Conflict Risk

The skill occupies a clear niche — a video catch-up tied to the specific /ketchup-video command — and explicitly differentiates itself from the related /ketchup skill ("instead of its summary and visuals"). Conflict risk with other skills is minimal, matching anchor 5.
