The body is mostly lean and assumes Claude's competence (no basic-concept padding), but it is ~260 lines with notable redundancy: the same grep targets (timers, location, background modes, audio) recur across Phase 1 mapping and Phase 2 detection, and the full output template is verbose. It is not level 3 because not every token earns its place, and not level 1 because it avoids explaining things Claude already knows.

It provides concrete, runnable grep patterns, exact file globs, copy-paste commands (`xcsym crash --format=summary`), and specific per-pattern verification and fix guidance. It is not level 2 because the search and verify instructions are executable throughout rather than pseudocode or vague direction.

Phases 1–5 are clearly sequenced with explicit validation checkpoints ("use Read to verify the surrounding context before reporting", "Require evidence from the Phase 1 map") and error-guard sections (False Positives, Output Limits). It is not level 2 because validation is explicit and feedback-oriented, not merely an uncheckpointed list of steps.

The skill is a single ~260-line file with substantial inline detail (8 detection patterns, four phase tables, a full output template) and no internal detail-file splitting; its only references point outward to sibling skills, not to this skill's own bundle. It is not level 1 because sections are well-organized rather than a nested-reference mess, and not level 3 because nothing is split into one-level-deep reference files.

The description is a pure trigger clause ("Use when the user mentions battery drain, energy optimization, power consumption audit, or pre-release energy check") and names no concrete actions or capabilities. It is weaker than the level-2 anchor, which requires naming a domain and some actions.

It explicitly answers "when" via the "Use when…" clause but entirely omits "what" — no statement of what the skill does. Since one of the two required parts is missing, this matches the level-1 anchor rather than level 2 (which expects what present, when implied) or level 3 (both explicit).

It lists four natural phrases a developer would actually say — "battery drain", "energy optimization", "power consumption audit", "pre-release energy check" — giving good coverage of the trigger space. It does not fall to 2 because the terms are natural and varied rather than jargon-only or missing common variations.

The triggers are narrowly scoped to energy/battery concerns, a clear niche distinct from performance, memory, or networking auditors, making wrong-skill activation unlikely. It is not level 2 because the trigger terms are specific enough to avoid meaningful overlap with sibling audit skills.
