Content
85%Reviews 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, actionable, and uses progressive disclosure effectively with real reference files. Its main weakness is conciseness: several rules (sidebar backgrounds, menu-bar text cap, single-file structure) are repeated across General Rules, pattern sections, and Anti-Patterns.
Suggestions
Consolidate the "avoid opaque custom Color fills on NavigationSplitView sidebars/root panes" guidance so it appears once; cross-reference it from the Anti-Patterns list instead of restating the full rationale three times.
Merge the duplicated 30-character menu-bar-item cap and the Window-vs-WindowGroup launch guidance into a single location rather than repeating them in both General Rules and Anti-Patterns.
Tighten the New App File Structure and Pre-Edit Checklist sections, which overlap on folder/state guidance, into one consolidated scaffold checklist.
| Dimension | Reasoning | Score |
|---|---|---|
Conciseness | Content is mostly efficient and assumes Claude's competence (no basic SwiftUI explanations), but several guidelines are restated multiple times — the "avoid opaque custom Color fills on sidebars" rule appears in General Rules, the Split-View Background Pattern, and Anti-Patterns, and the 30-char menu-bar cap and single-file anti-pattern each repeat — so it could be tightened. | 2 / 3 |
Actionability | Provides executable Swift code examples (sidebar row pattern, split-view do/don't backgrounds), a concrete file/folder structure, a state-ownership table, and specific commands like `git rev-parse --is-inside-work-tree`, giving copy-paste-ready guidance. | 3 / 3 |
Workflow Clarity | Includes a numbered 7-step "Workflow For A New macOS Scene Or View" with an explicit validation step ("Validate the flow with a build and a quick usability pass") plus a "Pre-Edit Checklist", sequencing the multi-step process with checkpoints. | 3 / 3 |
Progressive Disclosure | SKILL.md is a clear overview with a "Cross-Cutting References" section pointing to six real one-level-deep reference files (verified present in references/), each signaled with its scope and an entry-point index, keeping detail appropriately offloaded. | 3 / 3 |
