Conciseness

The 37-line body contains no filler and no explanations of concepts Claude already knows; every line is an instruction, a parameter, a regex, or an output-format specification. This matches the 5 anchor (lean, every token earns its place); it is not a 4 because there are no over-explanation instances to trim.

Actionability

Guidance is fully executable: the exact tool call (`mem0_memory` with `action="search"`, `query=<user's query>`), a UUID regex (`^[a-f0-9-]{20,}$`) for ID detection, a copy-ready output template with concrete example rows, and explicit empty-state handling. This matches the 5 anchor (copy-paste ready, common cases covered); not 4, since there are no minor gaps in the guidance.

Workflow Clarity

Three clearly sequenced steps (parse query, search, display) with explicit handling of edge cases: missing query ("What should I search for?"), UUID direct-lookup bypass, and a no-results message. The skill is read-only, so no destructive/batch validation cap applies, and the simple-skill exception (<50 lines, single task) is met with an unambiguous action. This fits the 5 anchor rather than 4 because even failure paths are specified.

Progressive Disclosure

No bundle files (references/scripts/assets) exist and none are needed; the skill is under 50 lines, self-contained, and organized into clear Execution/Step sections. Per the rubric guideline for short skills with no need for external references, well-organized sections alone score 5.

Specificity

The description lists several concrete actions — "Searches memories and displays compact one-liner results, or looks up a specific memory by ID" — which go beyond naming the domain, but coverage is not fully comprehensive (e.g., no mention of result ranking or output format). It is above the 3 anchor (which expects only 1-2 concrete actions) but short of the 5 anchor's comprehensiveness.

Completeness

Both questions are explicitly answered: the what ("Searches memories and displays compact one-liner results, or looks up a specific memory by ID") and the when ("Use for quick memory lookups, checking if something was recorded, resolving [mem0:id] citations, or browsing memories without full category detail"). The when clause contains concrete trigger phrases, matching the 5 anchor; it is not a 4 because the when is explicit and specific rather than improvable-vague.

Trigger Term Quality

Natural trigger phrases like "quick memory lookups", "checking if something was recorded", "resolving [mem0:id] citations", and "browsing memories" give good coverage, but common variations users might say (e.g., "recall", "what do you remember about") are missing. This matches the 4 anchor (good coverage, a few natural terms missing) rather than 5 (comprehensive with synonyms) or 3 (missing common variations entirely).

Distinctiveness Conflict Risk

The description carves a mostly distinct niche (compact search/lookup, [mem0:id] citation resolution) distinguishable from related add/delete/browse memory skills, but the term "browsing memories" carries minor overlap risk with a sibling memory-browsing skill. This fits the 4 anchor (mostly distinct, minor overlap) better than 5 (minimal conflict) or 3 (could still overlap with similar skills).
