Conciseness

The body is dense, non-obvious judgment guidance — it explains no concepts Claude already knows, and passages like the impatient-vs-stuck distinction earn their length. However, 'What consistently goes wrong' restates points already made in full sections (fluent-expert phrasing from 'Diagnose before you teach', over-delivering visuals from 'Showing, not just telling'), and a few rhetorical flourishes ('impatience wearing a costume') could be trimmed. Efficient with minor instances of over-explanation — anchor 4, not 5.

Actionability

For an instruction-only skill the guidance is fully concrete: exact diagnostic questions ("What's your best guess at where to start?"), a named toolkit of moves with when-to-use conditions, example dialogue ("I won't write the essay, but I'd like to help — want to talk through your argument?"), tool-call instructions ("call `read_me` once, silently... then call `show_widget`"), and per-scenario responses for quiz me / check my answer / just tell me. Specific examples cover the common cases — the top anchor for an instruction skill.

Workflow Clarity

The session flow is clearly sequenced — diagnose (with an explicit skip condition), one-step-per-turn rhythm, pressure handling with an explicit decision fork (impatient vs. genuinely stuck), and explicit termination criteria ("When the learner explains it back correctly... say so plainly"). It sits between anchors: more decision checkpoints than anchor 4, but 'What consistently goes wrong' is a prose recap rather than the stepwise checklist with feedback loops that anchor 5 describes, so 4 fits best.

Progressive Disclosure

There are no bundle files; the skill is a single well-organized SKILL.md with eight clear section headers, and a behavioral skill of this nature does not require external references — the guidance must be in context during a session. Good structure with content appropriately placed, matching anchor 4. Not 5: the body is ~60 lines (over the under-50-line simple-skill allowance) and sections like the widget workflow and integrity rules are long enough that split-out references were at least conceivable.

Specificity

The description states its purpose clearly — "wants intellectual understanding — learning how or why something works, not getting a task done or soliciting Claude's judgment" — but never enumerates the concrete tutoring actions the skill performs (diagnosing gaps, scaffolding, quizzing, building study materials). It clearly matches the anchor 'names domain and 1-2 concrete actions, but not comprehensive': one functional capability is explicit, actions are not. Not a 4, which requires several specific listed actions; not a 2, because the what/when framing is sharp rather than generic.

Completeness

Both what ("intellectual understanding — learning how or why something works, not getting a task done") and when ("Use this skill when..." plus an explicit 'Trigger for' list and a 'Don't trigger for' list) are answered explicitly with concrete trigger phrases. Matches the top anchor exactly; nothing below it fits, since neither half is vague or merely implied.

Trigger Term Quality

Comprehensive natural trigger phrases: "teach, explain, ELI5, walk me through, quiz me, flashcards, 'I'm rusty on'", "definitions ('what is X')", confusion signals ("won't stick", "keep mixing these up", "not getting it"), and learning-path phrasings — these are exactly what a user would say. Score 5 rather than 4 because synonym coverage spans explicit requests, terse concept names, and indirect confusion signals.

Distinctiveness Conflict Risk

A clear niche (learning/tutoring) with distinct triggers and an explicit negative scope — tasks ("coding, writing, calculation, translation, factual lookup"), "resource/textbook recommendations", and opinion prompts ("do you think X", "settle this") — that separates it from task, research, and judgment skills. Minimal conflict risk, matching the top anchor.
