Quality

Content

75%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.

A well-structured, actionable ten-step workflow with concrete commands and code, held back only by a long inlined template and the absence of explicit validation feedback loops.

Suggestions

Extract the large WebGL2 effect template into a references/ file and link to it, keeping SKILL.md as a leaner overview.

Add explicit feedback loops for failure-prone steps (e.g. 'If bun test fails, fix params and re-run before proceeding').

Tighten the rationale asides (e.g. the fit="cover" explanation) to one line each.

DimensionReasoningScore

Conciseness

The body is efficient and assumes Claude's competence (no generic explanations of WebGL or PDFs), but the large inlined effect template and a few rationale asides could be trimmed slightly.

4 / 5

Actionability

Concrete file paths, copy-paste shell commands, and a near-complete TypeScript template make the guidance mostly executable; the one undefined helper (createMyEffectState) is a minor gap, though explicitly deferred to existing files.

4 / 5

Workflow Clarity

Ten numbered steps are clearly sequenced with checkpoints (test runs, git diff --check, git status --short), but explicit validate→fix→retry feedback loops are not spelled out.

4 / 5

Progressive Disclosure

Well-organized into clearly headed sections with signaled pointers to other skills (writing-docs, docs-demo) and existing repo files; no bundle files exist, and the long inlined template is the main organization gap.

Description

75%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 highly specific, distinctive description that clearly states what the skill does, but it omits any explicit 'Use when...' trigger guidance, which limits its completeness score.

Suggestions

Append an explicit trigger clause, e.g. 'Use when adding a new effect to @remotion/effects or when the user asks to create, register, or document a Remotion effect.'

Add a few natural synonyms users might say (e.g. 'visual effect', 'shader effect') to broaden trigger-term coverage.

DimensionReasoningScore

Specificity

The description enumerates many concrete actions — 'implementation, package exports, docs, demos, preview images, Remotion skill updates, tests, formatting, and builds' — giving comprehensive coverage rather than vague language.

5 / 5

Completeness

The 'what' is clearly stated, but there is no explicit 'Use when...' clause or equivalent trigger guidance, which per the rubric caps completeness at 3.

3 / 5

Trigger Term Quality

Natural trigger phrases like 'Add a new effect' and '@remotion/effects' are present, but coverage lacks common synonyms or variations a user might say, so it sits just below comprehensive.

4 / 5

Distinctiveness Conflict Risk

The phrase 'Add a new effect to @remotion/effects' carves a clear, package-specific niche with minimal overlap risk against other skills.
