Conciseness

Mostly lean and assumes Claude's competence, with no filler explaining known concepts; minor trims remain — the 'Act as a senior AI-memory systems engineer' persona line, the four 'Official References' links, and the supersede/invalidate/add guidance repeated in both Protocol step 6 and the 'Conflicting facts' unhappy path. Fits 'efficient; minor instances of over-explanation' rather than 'every token earns its place'.

Actionability

Concrete throughout: exact MCP tool names with a need→tool table, argument guidance ('takes a short natural-language query … plus optional wing / room filters and limit (default 5)'), explicit decision rules for fact changes, and copy-paste-ready commands ('mempalace repair --mode from-sqlite --archive-existing --yes'). Matches 'fully executable; copy-paste ready code or commands; specific examples cover the common cases'.

Workflow Clarity

The numbered 6-step Protocol has explicit checkpoints ('If unsure about a fact: say "let me check the palace" and query', 'Stop when answered') plus four detailed unhappy-path recovery loops, including a repair sequence validated by 'mempalace repair-status' and a warning that re-mining 'drops MCP-added drawers and diary entries (#1843)'. Matches the anchor for clear sequencing with explicit validation and feedback loops.

Progressive Disclosure

A well-sectioned single-file skill with clearly signaled one-level-deep links ('The full canonical protocol … is published in the MemPalace repository'), but no bundled reference files exist and, at ~136 lines, the corrupt-index recovery and coordination-protocol detail could live in separate reference files. Fits 'good structure; most content is appropriately placed; minor organization gaps' rather than fully split content.

Specificity

It names the domain ('Recall protocol for MemPalace') and one concrete action — 'search the palace before answering' — but does not enumerate the skill's other concrete capabilities (verbatim quoting, KG queries, diary writes). Fits 'names domain and 1-2 concrete actions, but not comprehensive'; clearly below the 'several specific actions' anchor.

Completeness

It explicitly answers what ('search the palace before answering about past work, people, projects, or prior decisions') and when via an explicit 'Apply when…' clause listing concrete trigger phrases plus direct invocation ('or when mempalace-recall is invoked'). Matches the anchor for clearly and explicitly answering both what and when with concrete triggers.

Trigger Term Quality

Natural user phrasings like 'what was decided', 'what happened before', 'who someone is', and 'what was discussed last time' give good keyword coverage, but common variants ('remember when…', 'last session', 'previously') are absent. Matches 'good keyword coverage; a few natural terms missing' rather than comprehensive coverage.

Distinctiveness Conflict Risk

Clear niche (recall from the MemPalace memory palace) with an explicit boundary against the sibling skill — 'Complements the mempalace setup skill and requires the mempalace-mcp server' — and distinct question-shaped triggers. Matches 'clear niche with distinct triggers; minimal conflict risk'; not 4 because the overlap with the setup skill is explicitly delineated.
