Conciseness

Most of the body is lean, executable bash and concrete tool calls, but multi-paragraph explanations like the Check 2 identity/git rationale and the Check 6 auto-dream prose include context that could be tightened; it is above level 1 because it does not pad with concepts Claude already knows, yet below level 3 due to these explanatory stretches.

Actionability

Provides copy-paste-ready bash snippets and exact tool invocations with parameters (e.g. 'Call search_memories with query="health check", filters={...}, top_k=1' and the add_memory/get_event_status/delete_memory chain); fully executable rather than pseudocode, matching the level-3 anchor.

Workflow Clarity

Six checks are explicitly sequenced with 'Run ALL checks, then display a single summary. Do not stop on the first failure', each having PASS/WARN/FAIL criteria, and Check 4 includes a validate-then-cleanup feedback loop (add → get_event_status → delete_memory); this meets the clear-sequence-with-validation anchor rather than the level-2 'sequence present but checkpoints missing'.

Progressive Disclosure

No bundle files exist (references/scripts/assets absent), so the skill is a single self-contained document organized into clearly headed sections (Execution checks, Display, Extended mode, Output formatting); per the rubric's simple-skill guidance, well-organized sections with no need for external references score 3. It is not level 2 because navigation and sectioning are clear rather than a monolithic wall.

Specificity

Lists multiple concrete actions — 'Diagnoses mem0 connectivity, API key validity, and memory read/write functionality' — matching the anchor for several specific concrete actions; it is not the level-2 example because it names three distinct diagnostics rather than a single domain+action.

Completeness

Explicitly answers both what ('Diagnoses mem0 connectivity, API key validity, and memory read/write functionality') and when (explicit 'Use when ...' triggers), so it clears the level-3 bar; level 2 requires an absent or only-implied 'when', which is not the case here.

Trigger Term Quality

The 'Use when memory operations fail, searches return empty, add_memory errors occur, or to verify the plugin is working correctly' clause covers natural phrases a user would actually say; it is above level 2 because it spans several common failure framings rather than a single generic keyword.

Distinctiveness Conflict Risk

The mem0-specific scope and failure-trigger language ('add_memory errors', 'searches return empty') give it a clear niche unlikely to fire for unrelated skills; it is more distinct than the level-2 'Works with document files' anchor.
