Conciseness

Prose is lean (e.g., "Top-down map-style controls.") with comment-annotated code instead of explanations, but the exhaustive inline catalog of 8+ camera-control variants and repeated scaffolding (two OrbitControls sections, the disable-orbit pattern duplicated in TransformControls and DragControls) is over-coverage of APIs Claude largely already knows — anchor 4, not the fully lean anchor 5.

Actionability

Nearly all examples are complete, copy-paste-ready TSX with real props (full event-object field list, keyMap, useScroll). One real gap: the TransformControls example renders an HTML <div> inside <Canvas>, which will not execute as written — anchor 4 ("mostly executable... minor gaps"), not 5.

Workflow Clarity

This is a reference-style skill with no multi-step or destructive workflow, so no validation cap applies; sections are well-organized quick-start-first and each control variant carries a one-line use signal ("FPS-style controls", "Lock pointer for FPS games"). Missing guidance on choosing among the many control variants keeps it at anchor 4 rather than 5.

Progressive Disclosure

No bundle files exist and no references are given — ~880 lines of reference-grade material (the camera-controls catalog, gesture and scroll sections) that clearly belongs in separate reference files is inlined in SKILL.md. Header structure is good, matching anchor 3 ("some structure... content that should be separate is inline"), but nothing is split out, so it cannot reach anchor 4.

Specificity

Names the domain plus several concrete capability areas ("pointer events, controls, gestures, selection"), but they are topic nouns rather than actions and omit body-covered areas like keyboard input, drag, and scroll — minor gaps, matching anchor 4 rather than the comprehensive anchor 5.

Completeness

Clearly answers what ("React Three Fiber interaction - pointer events, controls, gestures, selection") and explicitly answers when with concrete trigger phrases ("Use when handling user input, implementing click detection, adding camera controls, or creating interactive 3D experiences"), exactly matching the anchor 5 example pattern.

Trigger Term Quality

Natural phrases users would actually say ("handling user input", "implementing click detection", "adding camera controls", "interactive 3D experiences") with good coverage, but common variations like hover, drag, or raycast are missing — anchor 4, not 3 (coverage is good, not partial) and not 5 (no synonyms/extensions).

Distinctiveness Conflict Risk

The R3F interaction niche is distinct, but broad triggers like "handling user input" and "interactive 3D experiences" carry minor overlap risk with sibling skills such as r3f-fundamentals or a generic three.js skill — anchor 4, not 5.
