Conciseness

Every section carries non-generic operational content — e.g., "Exit statuses 0 and 1 from `leaks` remain analyzable", "Capturing suspends the process", and "An isolated strong cycle can be unreachable and still consume memory" — with no tutorial-style explanation of concepts Claude already knows and no padding. It matches the lean/efficient anchor where every token earns its place; even version sensitivity is handled by deferring to "Current installed-tool help" rather than hardcoding versions.

Actionability

The two bash blocks are copy-paste ready with concrete paths, and the cited flags (`--bundle-id`, `--udid`, `--pretty`, `--app-image`, `--trace-limit`, `--group-by-type`, `--reference-tree`) match the actual argparse definitions in scripts/capture_sim_memgraph.py and scripts/summarize_memgraph.py. Specific tool queries (`leaks --traceTree=<address>`, `jq -er 'select(.status == "captured")...'`, `test -s`) cover the common cases, matching the fully-executable anchor.

Workflow Clarity

Six sequenced steps with explicit validation checkpoints and feedback loops: "The per-run `mkdir` must fail if the capture directory already exists", "zero or multiple matches are errors", the jq status check before summarization, and "A fix is supported when the same app-owned type/path disappears... across repeated runs". The Review Checklist plus the fix-and-reverify loop matches the level-5 anchor; this is investigative (not destructive/batch) work, so no cap applies.

Progressive Disclosure

The body is a well-sectioned overview with a Contents nav; the only deep content — the empty-leak growth branch — is split into references/reachable-growth.md and clearly signaled with a conditional load instruction ("Load reachable-growth.md only for this empty-leak branch; it contains the ordered `vmmap`, `heap`, `leaks`, and `malloc_history` queries"). Verified against the actual bundle: the reference file exists, is one level deep with no nested references, and both referenced scripts exist with matching flags — matching the well-signaled one-level-deep anchor.

Specificity

Quotes concrete actions and artifacts covering the full workflow: "Captures or analyzes iOS memgraph files and persistent heap growth with Apple CLI evidence, ownership paths, raw artifacts, and matched-flow verification" — capture, analysis, and fix-verification are all explicitly stated with concrete nouns. This matches the anchor for multiple specific concrete actions with comprehensive coverage, and exceeds the level-4 anchor because no capability of the skill (capture → analyze → verify) is left uncovered.

Completeness

Both questions are answered explicitly: what — "Captures or analyzes iOS memgraph files and persistent heap growth..."; when — "Use for leaks or memory-growth investigations". This satisfies the level-5 anchor (clear what AND when with concrete trigger phrases); the explicit "Use for..." clause also avoids the completeness cap of 3 for missing trigger guidance.

Trigger Term Quality

Natural terms are present — "leaks", "memory-growth investigations", "iOS", "memgraph files", "heap growth", "Xcode Memory Graph" — which users would plausibly say. It falls short of the level-5 anchor (comprehensive coverage including synonyms and extensions) because common phrasings like "memory leak", "out of memory/OOM", "memory footprint", or the ".memgraph" extension are absent, while exceeding level 3 since several distinct natural trigger phrases are covered.

Distinctiveness Conflict Risk

The niche is precise (iOS memgraph CLI analysis) and conflict is actively reduced by routing: "route interactive Xcode Memory Graph, Instruments, or LLDB work to debugging-instruments". This is a clear niche with distinct triggers and minimal conflict risk per the level-5 anchor; there is no overlap ambiguity with the named sibling skill.
