Conciseness

The body is substantive and avoids explaining concepts Claude already knows, but has real structural repetition: the Best Practices section restates Steps 2–5 nearly verbatim, Example 1 duplicates the entry template already shown in "What Following This Skill Produces", and the closing paragraphs restate Security/Limitations caveats. This is more than the "minor over-explanation" of a 4, though not severely padded like a 2.

Actionability

For an instruction-only skill the guidance is fully concrete: explicit lists of recall triggers, save triggers, and do-not-save items; copy-paste ready entry templates in text blocks; exact suggested phrasings for surfacing contradictions; and a concrete search strategy ("the words the user actually used, plus the project or repository name"). Not below 5 because no key execution detail is left abstract.

Workflow Clarity

Steps 1–6 are clearly sequenced with explicit checkpoints and error-recovery loops: recall fallback (one broader query, then proceed without memory), contradiction handling (surface both with dates and ask), rejected-save handling (report once, do not rephrase in a loop), and per-step pitfalls. No destructive or batch operations apply, so no cap is triggered.

Progressive Disclosure

The single bundle reference (references/entry-format.md) is real, one level deep, and clearly signaled from Step 3/4 context, and sections are well organized. It falls short of 5 because the body duplicates entry-format examples that already live in the reference file, and the Examples section carries content that could itself be pushed to the reference.

Specificity

The description names several concrete actions — "recall from long-term memory before acting" and "save decisions, corrections and failures afterwards" — with the save categories explicitly enumerated. Not a 5 because the recall/save sub-behaviors (closing superseded entries, contradiction handling) are absent from the description itself.

Completeness

The "what" is clear (standing rules for when to recall and when to save), but there is no "Use when..." clause or equivalent trigger guidance — "Works with any memory backend" states scope, not when to invoke the skill. Per the rubric guideline, a missing explicit trigger caps completeness at 3.

Trigger Term Quality

Natural terms like "long-term memory", "recall", "save", and "memory backend" are present, which users discussing memory would plausibly say. A few natural variations ("remember this", "forgets between sessions", "preferences") are missing, keeping it below 5.

Distinctiveness Conflict Risk

It occupies a clear niche (usage discipline for memory, not backend setup), distinct from most skills. Minor overlap risk remains with closely related memory-architecture or context-engineering skills, and the absence of explicit triggers makes it slightly less distinguishable than a 5.
