Quality

Content

88%Weight 40%Scale 1-5

Reviews the quality of instructions and guidance provided to agents. Good implementation is clear, handles edge cases, and produces reliable results.

The body is a well-sequenced, actionable workflow with executable code, explicit validation/verification checkpoints, and feedback loops, supported by a real one-level reference file. It is concise and respects Claude's competence with only minor trimming opportunities.

DimensionReasoningScore

Conciseness

Largely efficient and assumes Claude's competence (no explanation of what ffmpeg/git/Playwright are), with executable commands; minor padded passages like the extended subagent prompt block and the example script could be trimmed slightly.

4 / 5

Actionability

Provides copy-paste ready, executable commands (DEMO_RECORD_VIDEO Playwright invocation, ffmpeg trim/convert with explained -ss/-t flags, ffprobe/ffmpeg frame-extraction) and concrete helper names; the demo-patterns.md reference supplies complete templates.

5 / 5

Workflow Clarity

A clearly numbered six-phase pipeline (Research → Propose Script → Iterate → Record → Verify → Iterate) with explicit feedback loops: user-approval checkpoint before recording, subagent verification step, and a Phase 6 iteration map routing changes back to the correct phase.

5 / 5

Progressive Disclosure

Well-structured overview with one-level-deep references to the real references/demo-patterns.md (verified present) and to demo-utils.ts; minor gap in that the main body inlines a fairly long example script and subagent prompt that could arguably live in the reference.

Description

95%Weight 40%Scale 1-5

Based on the skill's description, can an agent find and select it at the right time? Clear, specific descriptions lead to better discovery.

The description is concise, specific, and provides concrete trigger phrases a user would naturally say, clearly answering both what and when. It is third-person and lean with no fluff.

DimensionReasoningScore

Specificity

Names the domain (Positron demo videos) and multiple concrete actions — 'create a demo video, record a feature walkthrough, or generate a video for a PR description' — with only minor coverage gaps (e.g., trimming/encoding not mentioned).

4 / 5

Completeness

Explicitly answers both 'what' (create demo videos / walkthroughs / PR videos) and 'when' (concrete 'Triggers on' trigger phrases), matching the anchor that requires both with concrete triggers.

5 / 5

Trigger Term Quality

Comprehensive natural trigger phrasing — 'record a demo', 'make a video', 'demo video for PR', 'generate a walkthrough' — covering the common ways a user would actually phrase the request.

5 / 5

Distinctiveness Conflict Risk

A clear niche (Positron feature demo videos for PRs) with specific triggers that are unlikely to collide with other skills; minimal conflict risk.
