Conciseness

The body is lean and assumes Claude's competence — no explanations of what memory or markdown is, every section carries operational weight. It is not 5 because of small redundancies: Rule 3 ('No duplicates - Update existing if same topic') restates Step 4, and Rule 1 ('structure with Why/How to apply') restates the file template.

Actionability

Concrete, executable guidance throughout: an exact file template with frontmatter fields, a memory directory path, a formatted output block, and worked examples for each memory type. It falls short of 5 because the path '.claude/projects/<project-hash>/memory/' leaves the placeholder unresolved with no instruction for resolving it, and no example entry format is given for the MEMORY.md index.

Workflow Clarity

Four steps are listed, but Step 4 ('Before creating a new file, check if a memory on the same topic already exists') contradicts its own position — it must logically precede Step 2 (Create Memory File), making the sequence incoherent on that point. There is also no validation checkpoint (e.g., confirming the write or index line count), fitting anchor 3 ('sequence present but checkpoints missing or implicit') rather than 4.

Progressive Disclosure

A single self-contained SKILL.md with well-organized sections (Workflow, Output, Examples, Rules) and no external references — appropriate for a skill of this scope, so nothing is wrongly inlined or buried. It does not reach 5 because at ~108 lines it exceeds the simple-skill threshold and has minor organization gaps, e.g., the Rules section duplicating workflow steps instead of consolidating them.

Specificity

The description names its domain concretely ("making a decision, choosing a convention, or learning a lesson that should persist across sessions") but never states any action the skill performs, matching the anchor 'Names the domain but actions are minimal or generic'. It scores above 1 because it is not pure abstract fluff like 'Helps with documents', but below 3 because no capability (e.g., writing memory files or updating an index) is ever mentioned.

Completeness

The description is entirely a 'when' clause ("Use when making a decision...") with no 'what' — the reader cannot tell the skill saves anything to memory. This exactly matches anchor 2 ('only when is present without what', example: 'Use when working with documents'). It is not 3 because the 'what' is not merely weak — it is absent.

Trigger Term Quality

Phrases like "making a decision", "choosing a convention", and "learning a lesson" are terms users would plausibly say, but the most natural invocations ("remember this", "save this preference", "keep this for future sessions") are missing. This fits anchor 3 ('Some relevant keywords but missing common variations or synonyms') rather than 4, which requires only a few missing natural terms.

Distinctiveness Conflict Risk

The qualifier "that should persist across sessions" creates a distinguishable niche, but the broad opening triggers "making a decision" could overlap with planning or decision-support skills, and the description does not mention the memory-file output that would distinguish it from the native auto-memory system. Fits anchor 3 ('Somewhat specific but could still overlap with similar skills') better than 4, which requires only minor overlap with closely related skills.
