Conciseness

The body is largely lean — compact tables, short rules, and templates Claude could not infer on its own — but there is minor duplication: "Core Teaching Rules" restates the strictness boundary already enforced in the "Strictness Enforcement" section, and the three techniques are summarized in the body while their details live in guidance-patterns.md. This fits the score-4 anchor (efficient; minor instances that could be trimmed) rather than 5, where every token would earn its place.

Actionability

Concrete, executable guidance throughout: a strictness-level table, ordered context-resolution rules, and copy-paste markdown templates for session start and exit. However, Step 1.1 instructs use of `AskUserQuestion` while the frontmatter allows only Read/Glob/Grep, and the "claude-pair label detected" mechanism is unspecified — small gaps that keep this at the score-4 anchor (mostly executable, minor gaps) rather than 5.

Workflow Clarity

A clearly sequenced three-step workflow (initialization with ordered sub-steps 1.1-1.4, guided session loop, exit summary) with a confirmation checkpoint before the loop starts and explicit error-recovery paths in "Handling Common Situations" (frustrated, partially correct, task too complex). This matches the score-5 anchor's clear sequence with feedback loops; the score-4 anchor's "minor validation gaps" do not apply, and no destructive/batch-operation cap is triggered.

Progressive Disclosure

The SKILL.md body is a clean overview that twice clearly signals [guidance-patterns.md](references/guidance-patterns.md), which exists and is exactly one level deep, containing the appropriately split-out teaching techniques, task patterns, and complexity calibration. This matches the score-5 anchor (clear overview with well-signaled one-level-deep references, content appropriately split).

Specificity

"asking guiding questions, providing hints, explaining concepts, and reviewing user-written code instead of writing solutions" lists four concrete, domain-specific actions that comprehensively cover the skill's behavior. This matches the score-5 anchor (multiple specific concrete actions, comprehensive coverage) rather than 4, since no meaningful capability gap remains.

Completeness

Explicitly answers both "what" ("Guided pair-programming mode where Claude teaches rather than solves...") and "when" ("Use when the user wants to learn while building: says...") with concrete trigger phrases. This mirrors the score-5 anchor example structure exactly; the score-4 anchor's "when could be more explicit" caveat does not apply.

Trigger Term Quality

The trigger list "teach me", "help me understand", "guide me", "walk me through", "mentor me", "don't just give me the answer", "learning mode", and "/pair" covers the natural phrases a user would actually say, including synonyms and the slash command. Matches the comprehensive coverage of the score-5 anchor; no file extensions exist for this behavioral domain to be missing.

Distinctiveness Conflict Risk

Triggers like "/pair", "learning mode", "mentor me", and "don't just give me the answer" establish a clear niche, but "walk me through" and "help me understand" are common phrases that could also fire on ordinary explanation requests, creating minor overlap risk with closely related skills. This fits the score-4 anchor (mostly distinct; minor overlap risk); score 5 would require near-zero overlap, and score 3 would understate the distinct mode framing.
