Conciseness

The body is dense with non-inferable contract detail (stage visibility, dedup/sort order, callback precedence, catalog vs callback semantics) and explains nothing Claude already knows, but it repeats itself — "both return `void`" appears in roughly four places, the no-loop/no-Promise.all rule appears twice, and the A/B-gate statistics sentence ("49 runs per variant per model: 24%→90% ... 63%→88%") is justification detail that earns no tokens. This matches level 4 (efficient with minor over-explanation that could be trimmed) rather than level 5's every-token-earns-its-place.

Actionability

Every feature ships complete, copy-paste-ready TypeScript: enabling onMemoriesSearch/onSkillsSearch, static catalogs, forward-time preloading, actor-side recall/discover turn usage, carrying memories across calls, relevanceRanking, and used-tracking, plus full type definitions and runnable example URLs. This matches level 5's fully executable coverage of the common cases.

Workflow Clarity

The enable → wire → actor-usage flow is unambiguous: 'Use These Defaults' acts as a decision procedure (catalog vs callback vs contextMap), actor usage is explicitly turn-sequenced ("Turn 1: kick off one batched lookup / Turn 2+: matched entries are now visible"), and a Do-Not-Generate section guards the failure modes. No destructive or batch operations are involved, so the validation cap does not apply, and the sequencing is explicit enough for level 5 rather than level 4's 'most checkpoints'.

Progressive Disclosure

No bundle files exist, and the entire ~440-line API reference — type definitions, per-option rule lists, cross-language persistence notes — is inlined in SKILL.md, matching level 3's 'content that should be separate is inline'. Headers are well organized and the example URLs are clearly signaled one level deep, which keeps it above level 2, but the placement gap is more than the 'minor organization gaps' of level 4 since effectively all detail lives in the main file.

Specificity

The 'what' is concrete — "generate correct AxAgent memory retrieval, context-map, and dynamic skill-loading code using @ax-llm/ax" names three capability areas plus the package — but the single composite action verb "generate ... code" stops short of the multiple distinct actions in the level-5 anchor. It sits above level 3 because all three feature areas are explicitly named with only minor coverage gaps.

Completeness

Both questions are answered explicitly: a clear 'what' ("generate correct AxAgent memory retrieval, context-map, and dynamic skill-loading code using @ax-llm/ax") and an explicit 'when' with concrete trigger phrases ("Use when the user asks about contextMap, ... recall(...), ... discover({ skills }), ..."). This mirrors the level-5 example structure exactly, and the missing-Use-when cap does not apply.

Trigger Term Quality

The "Use when the user asks about" clause enumerates essentially the full API surface (contextMap, onMemoriesSearch, memoriesCatalog, recall(...), inputs.memories, discover({ skills }), relevanceRanking hints, ...) alongside natural phrasings like "preloaded skills" and "carrying memories across forward() calls". A user needing this skill would say or paste exactly these identifiers, matching the comprehensive-synonyms level-5 anchor; no common variations are missing.

Distinctiveness Conflict Risk

The triggers are unique library-specific identifiers (AxAgentContextMap, recall(...), discover({ skills })) with a clear niche in @ax-llm/ax agent memory/skill loading, giving minimal conflict risk with generic or sibling skills. Level 5 fits; no broad or generic phrasing is present.
