72%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.
A well-structured, technically dense practices reference with strong progressive disclosure via real bundle files and concrete code tokens. The main gap is the absence of explicit validation/feedback checkpoints in its build sequence and no complete worked example.
Suggestions
Add one complete, copy-paste-ready worked example (e.g. a minimal high-DPI Canvas redraw loop) so the inline code tokens consolidate into an executable whole.
Introduce an explicit validation checkpoint in 'Core Practices' — e.g. verify backing-store size and redraw budget after step 1, or confirm hit-test coverage after step 5 — to give the sequence feedback loops.
Tighten the 'Overview' paragraph, which blends rationale and tradeoff prose that could be trimmed without losing actionable signal.
| Dimension | Reasoning | Score |
|---|---|---|
Conciseness | The body is dense and assumes Claude's knowledge of web/Canvas APIs rather than re-explaining them, with a few sentences that could be tightened further; it largely avoids padded conceptual explanation. | 4 / 5 |
Actionability | It provides concrete executable specifics such as `ctx.setTransform(pixelRatio, 0, 0, pixelRatio, 0, 0)`, `setPointerCapture()`, `getContext("2d", { willReadFrequently: true })`, and the backing-store memory formula, but lacks a single complete copy-paste worked example. | 4 / 5 |
Workflow Clarity | The numbered 'Core Practices' give a coherent build sequence (backing store, transforms, layers, hit testing, pointer handling), but there are no explicit validation checkpoints or feedback loops, so checkpoints are only implicit. | 3 / 5 |
Progressive Disclosure | The body is an organized overview that points to four real one-level-deep skill reference files (rendering-architecture, high-density-interaction, performance-playbook, sparklines-and-microcharts) plus shared foundations, clearly signaled and split into 'Shared theory' and 'Skill references'. | 5 / 5 |
