Conciseness

The body is lean and assumes Claude's competence; the classification table is necessary reference logic rather than padding, though the trailing "stores verbatim — no inference" note is mildly redundant.

Actionability

Gives the exact tool name (`mem0_memory`), exact parameters (`action="add"`, `content="..."`), and a precise confirmation template with an explicit truncation rule — fully executable guidance.

Workflow Clarity

Four clearly sequenced steps (Extract → Classify → Store → Confirm) with an input-validation checkpoint in Step 1; the operation is non-destructive, so the destructive-cap does not apply, but no post-store verification is specified.

Progressive Disclosure

A simple skill well under 50 lines with no need for external references, organized into clearly headed sections — meeting the simple-skill exception for a top score.

Specificity

Names the domain (memory storage) and two concrete actions — "Stores a memory verbatim" and "appropriate category classification" — but coverage is not comprehensive beyond those two.

Completeness

Explicitly states both what it does ("Stores a memory verbatim...with appropriate category classification") and when to use it ("Use when the user says..."), with concrete trigger phrases.

Trigger Term Quality

Includes several natural phrases users would actually say ("remember this", "save this", "store this", "note that") plus synonyms (preference, decision, goal, lesson), though a few common variants are absent.

Distinctiveness Conflict Risk

The verbatim-storage-plus-classification niche is fairly distinct, but generic triggers like "save this" / "note that" carry minor overlap risk with other note-taking or memory skills.
