Conciseness

The body is ~45 lines with zero padding: a dense signal-to-category table, an exact tool invocation, and an exact confirmation format. Nothing explains concepts Claude already knows, and every token earns its place.

Actionability

Fully executable guidance: the exact fallback question ("What should I remember?"), the exact tool call (mem0_memory with action="add" and content="..."), and a precise confirmation template with an 80-char truncation rule.

Workflow Clarity

Four clearly sequenced steps with a missing-input checkpoint (Step 1) and a default category ("anything else → lessons"). Not anchor 5 because there is no validation of the mem0_memory result or error-recovery guidance before confirming success in Step 4.

Progressive Disclosure

The skill is under 50 lines, single-purpose, needs no external references, and is organized into clean sections (Extract, Classify, Store, Confirm), which per the rubric's simple-skill guidance earns full marks. No bundle files exist to verify.

Specificity

"Stores a memory verbatim from user input with appropriate category classification" names the domain plus 1-2 concrete actions (store, classify), matching the anchor for 1-2 concrete actions without comprehensive coverage. Not a 4, since it stops at two actions rather than listing several specific ones.

Completeness

Explicitly answers both: what ("Stores a memory verbatim from user input with appropriate category classification") and when ("Use when the user says remember this, save this, store this, note that...") with concrete trigger phrases. Not a 4, because the when-clause is already fully explicit and specific, matching the top anchor.

Trigger Term Quality

"remember this, save this, store this, note that, or explicitly asks to record a preference, decision, goal, or lesson" gives good natural keyword coverage. Not a 5 because common variations like "don't forget this", "keep in mind", or the word "memory" itself are missing.

Distinctiveness Conflict Risk

A clear memory-storage niche with largely distinct triggers, but phrases like "save this" and "store this" carry minor overlap risk with file-saving or generic note-taking skills. Not a 5 due to that residual conflict risk; well above the broad-overlap anchors of 2-3.
