67%Weight 40%Scale 1-5Reviews the quality of instructions and guidance provided to agents. Good implementation is clear, handles edge cases, and produces reliable results.
The body is well structured with a concrete, executable v3 timeline example and sensible pre-flight checks (version inspection, DOM selector existence). Its weaknesses are marketing prose in the intro and Context sections, a dangling Example section, and no in-skill guidance for the v4 API or version detection.
Suggestions
Delete or drastically trim the intro paragraph and the "Context" section — 'jaw-dropping', 'awards-caliber', and 'lightweight but extremely powerful' add no actionable guidance.
Remove the dangling "## Example" section (it quotes a user request but shows nothing) or complete it with the expected animation output.
Concretize version handling: show how to detect the installed major version (e.g., check the animejs entry in package.json or node_modules/animejs/package.json) and either include a v4 createTimeline() snippet or restructure the version caveat into a dedicated compatibility note.
| Dimension | Reasoning | Score |
|---|---|---|
Conciseness | The intro ("lightweight but extremely powerful JavaScript animation engine. It excels at...") and the Context section ("high-fidelity, jaw-dropping web animations... the tool of choice for awards-caliber interactive sites") are non-actionable puffery explaining things Claude already knows — more than the 'minor instances' of a 4, though the workflow and code sections themselves are lean. Matches 'mostly efficient but includes some unnecessary explanation'. | 3 / 5 |
Actionability | Provides mostly executable guidance: a concrete import ("import anime from 'animejs'"), a real timeline example ("anime.timeline({ easing: 'spring(1, 80, 10, 0)'...})", "anime.stagger(100)", a "'-=800'" offset), and specific easing advice. Not a 5: only one code example is given, "Inspect the installed major version first" lacks a concrete command, and v4 usage is deferred entirely to external docs rather than shown. | 4 / 5 |
Workflow Clarity | The four-step Execution Workflow (Identify Targets → Define Properties & Easing → Orchestrate Timelines → Implement) is clearly sequenced, with explicit pre-flight checks ("Inspect the installed major version first", "The selectors must exist in the rendered DOM") — matching 'clear sequence with most checkpoints present, minor validation gaps'. Not a 5: there is no post-implementation verification or error-recovery loop; not a 3 since checkpoints are explicit rather than missing, and the task is non-destructive so no cap applies. | 4 / 5 |
Progressive Disclosure | A well-organized single-file skill (~59 lines) with clear section headers (When to Use, Execution Workflow, Motion and Compatibility, Limitations) and one clearly signaled external link to the official timeline documentation; no bundle files exist, so nothing is inlined that belongs elsewhere. Not a 5: the "## Example" section is a dangling stub that quotes a user request without showing any output, and the skill sits just past the simple-skill threshold. | 4 / 5 |
