Conciseness

The body is lean: a compact parameter table, short bullet lists for "Memory Types" and "Importance Levels", and two minimal JSON payloads — every section adds operational detail Claude would not infer, with no padding or explanations of known concepts. Not 4: there is nothing identifiable to trim.

Actionability

The two examples ("用户喜欢简洁的代码风格" with type preference, and the path-separator error lesson) are complete, copy-paste-ready JSON payloads, and the parameter table fully specifies types, required flags, and the default ("重要性（0-1），默认 0.5"). Not 4: no gaps remain — the common cases (preference and error recording) are both exemplified and the remaining types are trivially inferable from the enumerated list.

Workflow Clarity

This is a simple single-purpose skill (one tool call with content/type/importance) and the single action is unambiguous from the parameter table and examples, so it earns 5 under the simple-skill exception. No validation cap applies since writing a memory entry is neither destructive nor a batch operation.

Progressive Disclosure

The body is under 50 lines with no need for external references (no references/, scripts/, or assets/ directories exist, and none are linked), and the content is organized into clear well-labeled sections (Parameters, Memory Types, Importance Levels, Examples, Related Skills), matching the simple-skill guidance for a top score.

Specificity

"Record important information to long-term memory" names the domain and one core action with target categories ("user preferences, successful patterns, and error lessons"), which matches anchor 3 — but the rubric penalizes second-person voice ("When you need to remember...") by reducing specificity by 1, giving 2. It is above anchor 1 because it is not pure abstraction, and above the vague-domain-only anchor 2 in substance, but the penalty and the single generic verb "Record" keep it from 3-4.

Completeness

It has both a clear 'what' ("Record important information to long-term memory for learning...") and an explicit 'when' clause ("When you need to remember user preferences..."). Not 5: the 'when' clause is a circular restatement of the 'what' rather than distinct concrete trigger phrases; not 3: the 'when' guidance is explicit, not merely implied.

Trigger Term Quality

The phrases "remember user preferences", "save successful patterns", and "record lessons from errors" are natural things a user would say, giving good keyword coverage. Not 5: common synonyms like "keep this in mind", "note this", or "don't forget" are missing; not 3: the terms go beyond a single generic keyword.

Distinctiveness Conflict Risk

The memory-recording niche ("long-term memory", "error lessons", "successful patterns") is mostly distinct with clear triggers. Not 5: "important information" is broad and the triggers could overlap with closely related sibling skills like search-memory; not 3: the listed triggers are specific enough to avoid general overlap.
