Conciseness

The thin-index body has no concept-explaining filler — tables carry mode detection, phases, tiers, and gates, and "Read only what the current operation asks for" signals restraint. However, the phase tables' "Rule" column repeats links already enumerated in the Required Reading table, and the Storage Layout section duplicates detail delegated to `rules/storage-layout.md`, so minor trimming is possible — the 4 anchor rather than the every-token-earns-its-place 5 anchor.

Actionability

Concrete, executable guidance throughout: a mode-detection table with `$0` checks and trigger phrases, a literal one-line operation/scope/tier output example, exact storage paths, a literal pointer snippet, and copy-paste artifacts like "Saved N memories to <scope> (<tier>)." It falls short of the 5 anchor because key executable detail (entry-file formats, the never-store list contents, diff/preview format) lives entirely in delegated files.

Workflow Clarity

Each operation has a numbered phase table with an explicit named Gate, the rule "Do not proceed to the next phase until the prior phase's gate passes", consent previews, explicit user confirmation for destructive `forget` runs, AUDIT.log appends, and per-operation Definition of Done checklists — explicit validation and checklists matching the 5 anchor. The destructive/batch cap of 3 does not apply since validation steps are emphatically present.

Progressive Disclosure

On paper this is an exemplary index: a Required Reading by Operation table, one-level-deep pointers, and per-section "full rules in ..." signals. But scored against the actual bundle, every referenced `rules/*.md` and `templates/*.md` file is absent — only `references/research-sources.md` exists — so the disclosure scheme cannot actually execute and navigation dead-ends. Good structure undermined by missing referenced files lands at the 3 anchor; it would score 5 if the referenced bundle files shipped.

Specificity

The description lists all four operations with concrete sub-steps ("extract candidates, resolve as ADD / UPDATE / DELETE / NOOP per Mem0", "load a ≤ 200-line INDEX, fetch detail on demand", "delete or redact with audit"), plus three storage tiers with literal paths and enforcement rules ("never-store list (secrets, keys, financial and identity numbers)"). Coverage of what the skill does is comprehensive, matching the top anchor; the only weakness is the tangential LoreKit sentence, which adds jargon but not missing capability.

Completeness

Both what and when are explicit: operations, tiers, and enforcement describe the capability, and "Triggers on ..." enumerates concrete trigger phrases. This matches the 5 anchor ("Clearly and explicitly answers both what AND when with concrete trigger phrases"); the 4 anchor's weaker "when" does not apply.

Trigger Term Quality

Concrete trigger phrases are listed ("remember this", "save to memory", "recall memory", "what do you remember about", "consolidate memory", "forget that") and map naturally to each operation, but common synonyms like "don't forget this", "keep in mind", or "what do you know about" are absent. Good coverage with a few natural terms missing, matching the 4 anchor rather than the comprehensive 5 anchor.

Distinctiveness Conflict Risk

The topic-scoped markdown memory niche with distinct operation triggers is mostly distinct, but phrases like "remember this" and "save to memory" are generic enough to overlap with built-in or other memory skills — minor overlap risk with closely related skills, matching the 4 anchor rather than the minimal-conflict 5 anchor.
