92%Reviews the quality of instructions and guidance provided to agents. Good implementation is clear, handles edge cases, and produces reliable results.
A tight, competent pattern skill: real code skeletons, a clear numbered workflow with an anti-pattern correction loop, and no concept fluff. The only gap is progressive disclosure — everything is inline with no reference files to absorb the denser sections.
Suggestions
Move the "Existing subclasses to read for reference" list and/or the "Customizing grid behavior" deep dive into a references/ file (e.g. REFERENCES.md) and link to it one level deep, keeping SKILL.md as a lean overview.
Tighten the slight overlap between the strategy mentions in "The pattern" and the fuller "Two data strategies" section so each section carries distinct information.
Replace the "(or similar)" hedge on the fetchData signature with the concrete base-class signature so the code skeleton is fully copy-paste ready.
| Dimension | Reasoning | Score |
|---|---|---|
Conciseness | Lean and assumes Claude's competence: it never explains what React, useEffect, or virtualization are, and every section adds domain-specific value. The embed/fetchData strategies are revisited in "Two data strategies" but the second pass adds new detail (cache, cell(), schema ownership, sizing guidance) rather than padding, so it stays at 3 rather than 2. | 3 / 3 |
Actionability | Provides concrete, syntactically valid TSX skeletons (useState(() => new MySubclass()), dispose effects, <PositronDataGrid instance={...} />, instance.setItems(items)) and names real subclasses to read. Placeholders like MySubclass are intrinsic to a pattern skill, not laziness; not 2 because the code is real, not pseudocode. | 3 / 3 |
Workflow Clarity | The numbered 5-step "pattern" sequence plus the anti-pattern "Symptoms... If you see those, delete the wrapper" correction loop and the closing checklist give an explicit sequence with error-detection checkpoints. Not 2 because validation/correction guidance is present, not just a bare step list. | 3 / 3 |
Progressive Disclosure | No bundle files exist (references/scripts/assets absent) and all content is inline in SKILL.md at ~130 lines. Sections are well organized, but there is no one-level-deep file disclosure to offload detail such as the per-subclass reference notes or the customizing-grid deep dive. Not 1 because it is well sectioned rather than a monolithic wall, and not 3 because there are no signaled external references. | 2 / 3 |
