Conciseness

The body is lean and imperative with no padding and no explanation of concepts Claude already knows; every section carries non-obvious operational knowledge (e.g., 'Exit statuses 0 and 1 from leaks remain analyzable', 'Capturing suspends the process', the mkdir-must-fail rule). The slight overlap between Common Mistakes and Review Checklist serves distinct purposes and does not rise to trimmable over-explanation.

Actionability

The workflow gives copy-paste-ready, fully executable commands — the capture script with --bundle-id/--output-dir/--udid flags, a jq extraction of the graph path, `test -s`, and the summarize script with flag semantics — and both referenced scripts exist in the bundle. Common cases (ambiguous Simulator, stale run directory, empty-leak growth) are explicitly covered.

Workflow Clarity

A clearly sequenced six-step workflow with explicit validation checkpoints at every risky point: the per-run mkdir must fail if the directory exists, 'zero or multiple matches are errors', `test -s` on the graph, exit-status handling rules, a pre/post fix-verification feedback loop, and a final Review Checklist. Not 4 because checkpoints and error-recovery guidance are present throughout, not just 'most'.

Progressive Disclosure

Structure matches the top anchor: a Contents TOC, one reference file (reachable-growth.md) exactly one level deep, loaded conditionally and clearly signaled ('only for this empty-leak branch'), with the deeper tool-query detail correctly split out of SKILL.md. Both referenced scripts exist on disk and are wired into the workflow; the reference file itself contains no nested references.

Specificity

The description lists multiple concrete, tool-named actions — 'unambiguous Simulator capture, leaks/heap/vmmap/malloc_history evidence, raw artifact preservation, and same-flow verification' — covering the domain comprehensively. It matches the 'multiple specific concrete actions; comprehensive coverage' anchor; it is not 4 because there are no meaningful coverage gaps.

Completeness

It explicitly answers 'when' ('Use when capturing or analyzing an iOS .memgraph, especially when the task mentions a memory leak...') and 'what' ('Covers unambiguous Simulator capture, leaks/heap/vmmap/malloc_history evidence, raw artifact preservation, and same-flow verification') with concrete trigger phrases. This matches the top anchor exactly.

Trigger Term Quality

It covers natural user phrasings with synonyms — 'memory leak, heap growth, persistent memory increase, ownership path, or matched-capture comparison' — plus the '.memgraph' file extension itself. It is not 4 because no common variation is missing; interactive-tool variants are deliberately and explicitly delegated elsewhere.

Distinctiveness Conflict Risk

It carves out a clear niche (CLI .memgraph capture and ownership analysis) and explicitly routes the nearest neighbor: 'Use debugging-instruments for interactive Xcode Memory Graph, Instruments, generic retain-cycle inspection, or LLDB work.' Conflict risk is minimal.
