Conciseness

The body is lean and assumes Claude's competence throughout — no space is spent explaining what auto-memory is. Only minor trimming opportunities exist (the "Tips" section is advisory rather than instructive). It is not anchor 5 because the Tips and When-to-Use sections add a small amount of non-essential token spend.

Actionability

Provides an executable bash snippet for locating the memory directory, explicit per-entry criteria lists, and a copy-paste-ready report template. Minor gaps remain, e.g., "Appeared in 2+ sessions (check wording patterns)" is a heuristic rather than an executable check, keeping it below the fully-executable anchor 5.

Workflow Clarity

A clearly sequenced 5-step workflow with a validation checkpoint for the missing-directory case and a `find`-based staleness verification. The skill is read-only analysis, so the destructive/batch validation cap does not apply; it fits anchor 4 (most checkpoints present, minor gaps) rather than anchor 5, which would require explicit error-recovery feedback loops.

Progressive Disclosure

The skill is a single self-contained file with no bundle files (no references/, scripts/, or assets/ directories) and clean section organization; nothing that belongs in a separate file is inlined. This sits above anchor 3's 'could be better organized' but below anchor 5, whose one-level-deep reference structure is not applicable to a self-contained skill of this length.

Specificity

"Analyze auto-memory for promotion candidates, stale entries, consolidation opportunities, and health metrics" names the domain and four concrete output categories. It stops short of the anchor-5 pattern of multiple distinct action verbs, but far exceeds the 1-2 actions of anchor 3.

Completeness

It explicitly answers both what ("Analyze auto-memory for promotion candidates, stale entries, consolidation opportunities, and health metrics") and when ("Use when the user runs /si:memory-review or asks what has been learned...") with concrete trigger phrases. Not anchor 4, since the 'when' clause is explicit rather than merely present-but-imprecise.

Trigger Term Quality

Triggers like "the user runs /si:memory-review", "asks what has been learned", and "what should be promoted or pruned" are natural user phrasings, but common variations such as "review memory" or "MEMORY.md" are absent, matching the anchor-4 'a few natural terms missing' profile.

Distinctiveness Conflict Risk

The niche is distinct, anchored to the specific command "/si:memory-review" and auto-memory auditing. Minor overlap risk remains with generic memory-management or memory-status skills, so it fits anchor 4 rather than the minimal-conflict profile of anchor 5.
