Quality

Content

65%

Reviews the quality of instructions and guidance provided to agents. Good implementation is clear, handles edge cases, and produces reliable results.

The body is highly actionable with specific, executable Xcode build-optimization guidance, but it is weakened by redundant duplicated sections and a lack of progressive disclosure or validation checkpoints.

Suggestions

Merge the overlapping 'What You Check' and 'Scan Process' sections so each Glob pattern and grep command appears once, cutting roughly a third of the body.

Add an explicit verification checkpoint in the scan process, e.g. confirm project.pbxproj was found before scanning settings, and a 'measure before and after' validation step tied to the report.

Consider splitting the detailed settings reference into a references/ file so SKILL.md stays a concise overview pointing one level deep.

DimensionReasoningScore

Conciseness

The ~190-line body duplicates content between 'What You Check' and 'Scan Process' (same Glob patterns and grep commands repeated), so it could be tightened, though it avoids explaining concepts Claude already knows.

2 / 3

Actionability

It provides exact build-setting names with expected values, copy-paste grep/xcodebuild commands, and concrete ❌/✅ bash fix examples, all fully executable.

3 / 3

Workflow Clarity

Steps 1–5 are sequenced with a defined output format, but there are no explicit validation checkpoints; the sequence is present yet checkpoints are only implicit.

2 / 3

Progressive Disclosure

The skill is a single monolithic file over 50 lines with no bundle references, though it is organized into clear sections that keep it navigable.

Description

22%

Based on the skill's description, can an agent find and select it at the right time? Clear, specific descriptions lead to better discovery.

The description functions only as a trigger clause and omits any statement of what the skill does, leaving it incomplete and low on action specificity. Trigger terms are relevant but limited in coverage.

Suggestions

Add a 'what' clause naming concrete actions, e.g. 'Scans Xcode projects for build-setting and build-phase bottlenecks and recommends fixes to reduce build time.'

Broaden trigger terms to include common variations like 'compile time', 'build is slow', 'incremental builds', and 'Xcode build times'.

Keep the third-person 'Use when…' trigger but pair it with the capability statement so both what and when are explicit.

DimensionReasoningScore

Specificity

The description only lists trigger conditions ('slow builds, build performance, or build time optimization') and names no concrete actions the skill performs, matching the anchor for vague or no actions.

1 / 3

Completeness

It has an explicit 'Use when' trigger (the 'when') but entirely omits what the skill does, so it fails the 'what AND when' requirement.

1 / 3

Trigger Term Quality

'slow builds, build performance, build time optimization' are natural user terms, but coverage is thin and misses common variations like 'compile time', 'build is slow', or 'reduce build time'.

2 / 3

Distinctiveness Conflict Risk

The build-performance niche is fairly distinct, but with no stated action it could still overlap with general performance-tuning skills.
