Conciseness

The body is efficient and documents proprietary knowledge (Picoschema syntax, bm_* tool semantics) Claude doesn't already have, but "Key Principles" restates facts the bm_write example already shows ("note_type='schema' marks it as a schema definition", "version: 1 in metadata") and the "Complete Example" recombines the earlier syntax snippets. This matches the 4 anchor ('minor instances of over-explanation that could be trimmed'), not the 5 anchor where every token earns its place.

Actionability

Fully executable, copy-paste-ready calls with complete parameters: bm_schema(command="infer", note_type="Meeting", threshold=0.5, project="<project>"), full bm_write payloads including metadata and content, and complete bm_edit set_metadata examples. Specific examples cover the common cases (infer, create, validate, diff, evolve), matching the 5 anchor.

Workflow Clarity

The Workflow Summary gives a sequenced 6-step lifecycle, and Schema Evolution embeds an explicit feedback loop: "Re-validate to confirm existing notes still pass" followed by "Fix outliers — update notes that don't conform". Clear sequence with explicit validation steps and error recovery matches the 5 anchor, not the 4 anchor which allows validation gaps.

Progressive Disclosure

No bundle files exist, and the single SKILL.md is well-organized with clear, scannable sections (When to Use, syntax reference, per-task sections, workflow summary). However, the ~100-line Picoschema Syntax Reference is inline reference material that could be split into a separate file — good structure with minor organization gaps matches the 4 anchor rather than the 5 anchor's clean overview-plus-references split.

Specificity

Quotes: "find unschemaed notes, infer and edit schemas, validate notes, detect drift" — four concrete, distinct actions covering the full schema-management lifecycle, matching the 5 anchor ('multiple specific concrete actions; comprehensive coverage'). It exceeds the 4 anchor, which allows minor coverage gaps.

Completeness

Quotes: "Manage Basic Memory schemas: find unschemaed notes, infer and edit schemas, validate notes, detect drift" (explicit what) and "Use when structured note types (Task, Person, Meeting) need consistency across the graph" (explicit when with concrete triggers). Both halves are clearly present, matching the 5 anchor rather than the 4 anchor's weaker 'when'.

Trigger Term Quality

Quotes: "schemas", "validate notes", "detect drift", "structured note types (Task, Person, Meeting)" — good natural keyword coverage a Basic Memory user would say. Not 5: common synonyms/variants like "templates", "frontmatter", or "knowledge base" are missing.

Distinctiveness Conflict Risk

Quotes: "Basic Memory schemas", "detect drift", "Picoschema"-adjacent vocabulary ("structured note types") — a clear niche with distinct triggers that would rarely fire for unrelated skills. Minimal conflict risk matches the 5 anchor.
