Conciseness

About 46 lean lines covering a complex multi-step workflow with zero concept explanations and no padding; every prohibition encodes a concrete failure mode ("do not search it for frames", "never shell automation", "do not reconstruct them"). Matches anchor 5 (every token earns its place); the occasional repeated constraint is deliberate reinforcement rather than over-explanation.

Actionability

Fully executable guidance: exact tool calls ("computer_use.cua.start_recording" with "record_video: false"), copy-paste renderer commands for both bash and PowerShell, a complete JSON manifest schema with exact field names, and precise point-annotation copy rules ({x, y, coordinateWidth, coordinateHeight}). Matches anchor 5 (copy-paste ready, covers the common cases).

Workflow Clarity

A clearly sequenced 6-step process with explicit validation ("Check the renderer's resolvedTargets against the intended controls... Correct any mismatch before returning fileMarker verbatim"), verification of intermediate states in steps 3-4, and retry guidance ("Keep valid captures across retries rather than re-recording"). Destructive actions are explicitly gated, so the destructive/batch cap does not apply. Matches anchor 5.

Progressive Disclosure

The body is under 50 lines with well-organized sections; renderer implementation is correctly externalized to the bundled script scripts/render-tutorial.mjs, which exists and is invoked by exact path; no nested or buried references. Per the rubric's simple-skill guidance this matches anchor 5.

Specificity

Names the domain and one concrete composite action ("Create an annotated MP4 tutorial from a workflow demonstrated in the owner's actual application") but lists only that single action rather than several, leaving coverage of demonstrating, captioning, and rendering implicit. Matches anchor 3 (1-2 concrete actions, not comprehensive); not anchor 4 since it does not list several specific actions.

Completeness

Explicitly answers both: what ("Create an annotated MP4 tutorial from a workflow demonstrated in the owner's actual application") and when with a concrete trigger phrase ("Use when asked for a tutorial video") plus a negative disambiguator ("not merely to watch an action live"). Matches anchor 5 clearly.

Trigger Term Quality

Includes the primary natural phrase "asked for a tutorial video" plus "MP4" and the distinguishing "watch an action live", but misses common variations users would say such as "how-to video", "walkthrough", "demo video", or "screen recording". Anchor 3 fits (relevant keywords missing common synonyms); anchor 4 would require only a few missing terms.

Distinctiveness Conflict Risk

Clear niche (annotated tutorial videos produced from live demonstration) with distinct triggers; the negative clause actively prevents mis-triggering against a live-viewing skill. Matches anchor 5 (clear niche, minimal conflict risk).
