The body is mostly efficient, but the 'Critical Principle' section restates the anchoring-bias rationale already implied by the rules, and the full report-format markdown template is elaborate; it could be tightened without losing clarity.

Provides a concrete agent-to-reference table, a copy-paste-ready prompt template with explicit placeholders, and specific Grep/Glob detection guidance, giving fully executable guidance.

Steps are clearly sequenced (detect stack, spawn agents, consolidate), but this batch operation across 13 agents has no validation/feedback checkpoint in the consolidate phase, capping workflow clarity per the rubric's batch-operation rule.

SKILL.md is a clear orchestration overview with a well-signaled, one-level-deep reference table; all 15 referenced files exist on disk and content is appropriately split between SKILL.md and references/.

Lists multiple concrete actions ('hunts for performance anti-patterns, inefficiencies, and suboptimal code', 'pattern-based detection (Grep/Glob)') and enumerates 15 specific optimization domains, matching the 'lists multiple specific concrete actions' anchor.

Explicitly answers what the skill does ('Deep code optimization audit using parallel specialist agents') and when to use it via a 'Use when asked to...' clause with explicit triggers, satisfying both what AND when.

Includes a broad set of natural user phrases ('optimize my code', 'find performance issues', 'speed up my app', 'find bottlenecks', 'code review for performance') plus Spanish variants, giving good coverage of terms users would actually say.

The performance-optimization niche is clear, but broad triggers like 'audit code quality', 'code review for performance', and 'code smell detection' could overlap with general code-review or linting skills, so it is somewhat specific but not fully conflict-free.
