Quality

Content

92%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.

An exemplary lean skill body: dense with earned, project-specific knowledge, concrete commands, and explicit verification checkpoints at every risky stage. The only gap is that the screenshot capture operation itself is described by parameters rather than an executable command.

DimensionReasoningScore

Conciseness

Every line carries non-obvious project knowledge ('building only CLI dependencies misses fonts, noise, and layout utilities', 'Empty render-delay handles alone do not establish that timeline media has finished loading') with no padding and no explanation of concepts Claude already knows.

5 / 5

Actionability

Gives exact commands (studio startup, bun install, turbo make filter, a fully specified render command) and precise parameters (1280x800 at DSF 2, 336-pixel panel, 2560x1600 pixels, frame 2025, baseline revision hash, 6s at 60fps timing). The core screenshot capture step, however, specifies framing but no executable capture command or script, leaving a minor gap.

4 / 5

Workflow Clarity

The multi-step process (matching captures, historical baseline checkout, reveal construction, render, verification, upload) is clearly sequenced with explicit validation checkpoints: 'inspect a screenshot before saving the final captures', 'verifying the public SHA-256 hashes', 'Preserve saved screenshots until their R2 uploads are verified', and inspecting beginning/midpoint/ending of the exported video plus lint checks.

5 / 5

Progressive Disclosure

Well-organized sections with no inlined content that belongs in separate files; detail is appropriately delegated to sibling skills via clearly signaled, one-level-deep references (offload-r2, remotion-render, upload-r2). No bundle files are needed, so the body-level structure fully suffices.

Description

87%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.

A strong description: third-person, concise, and specific about both capability and trigger conditions. It carves out a clear niche and would reliably fire on timeline layout comparison requests; only minor keyword variations and the render/delivery steps are absent.

DimensionReasoningScore

Specificity

Names several concrete, parameterized actions ('Capture matching 2x Remotion Studio timeline screenshots', 'make a before/after crop reveal in packages/brand', 'recapturing a historical layout') but omits the render and upload/delivery steps the body covers, so coverage is not comprehensive.

4 / 5

Completeness

Explicitly answers both what ('Capture matching 2x... screenshots and make a before/after crop reveal') and when ('Use for timeline layout comparison videos, including recapturing a historical layout') with concrete trigger phrasing. Not 4 because the 'when' clause is already explicit and specific rather than generic.

5 / 5

Trigger Term Quality

Includes natural terms users would say ('timeline', 'layout comparison videos', 'before/after', 'historical layout'), giving good coverage; a few natural variations (e.g. 'layout change video', 'before/after comparison') are missing.

4 / 5

Distinctiveness Conflict Risk

The 'Remotion Studio timeline screenshots' and 'packages/brand crop reveal' niche is highly distinct with its own triggers, so conflict with other skills is minimal.
