Conciseness

The body is largely lean and assumes competence (no concept explanations, terse command-first steps), but has minor redundancy: "If memsearch is not found, try/use uvx memsearch instead" appears in both Steps 1 and 4, and the Step 3 fallback paragraph over-explains the sandbox rationale. This sits between anchor 5's 'every token earns its place' and anchor 3's 'some unnecessary explanation' — noticeably above the midpoint.

Actionability

Mostly executable: concrete commands like `memsearch search "<query>" --top-k 5 --json-output --default-collection` and fully-formed `MDIR=...` exploration snippets. However the entry-point collection-derivation command embeds an unresolved `__INSTALL_DIR__` placeholder and several commands use placeholder args, so it is not fully copy-paste ready — matching anchor 4's 'concrete code or commands with minor gaps' rather than anchor 5.

Workflow Clarity

Clear 5-step sequence (Search → Evaluate → Expand → Deep drill → Return) with explicit error-recovery feedback loops: uvx fallback when the binary is missing, direct file read when expand hits a lock error, and direct transcript-file exploration for unrecognized formats. The Evaluate step acts as a quality checkpoint; this is not a destructive/batch operation, so no validation cap applies.

Progressive Disclosure

No bundle files exist, and the body is under 50 lines with no need for external references — per the rubric's simple-skill guidance, well-organized sections alone warrant the top score. Sections (Project Collection, Steps, When unsure what to search, Output Format) are clear and each is appropriately scoped with nothing that belongs in a separate file.

Specificity

Lists multiple concrete actions — "Search and recall relevant memories from past sessions via memsearch", "search for 3-5 chunks, expand the most relevant, optionally deep-drill into original transcripts" — covering the full capability surface. This matches the anchor for comprehensive concrete actions; anchor 4 would require noticeable coverage gaps, which are absent.

Completeness

Explicitly answers both what ("Search and recall relevant memories from past sessions via memsearch" plus the search/expand/deep-drill flow) and when (a clear "Use when..." clause with concrete trigger phrases, plus explicit skip conditions). This is a direct match for the anchor requiring both what and when with concrete trigger phrases.

Trigger Term Quality

Comprehensive natural phrasing users would actually say: "past decisions", "debugging notes", "previous conversations", "project knowledge", and quoted example questions like "why did we do Y" and "have I seen this before". Coverage includes synonyms and even a literal injected capability-hint trigger, exceeding anchor 4's 'a few natural terms missing'.

Distinctiveness Conflict Risk

Clear niche (memory recall via the memsearch tool) with distinct triggers, including the literal `[memsearch] Recall available if needed` hint. Explicit skip guidance ("purely about current code state (use Read/Grep)") further reduces mis-triggering; no meaningful overlap with anchor 4's 'minor overlap risk with closely related skills'.
