Conciseness

The ~20-line body is lean and efficient: 'look around — confirm the target object is visible in the scene', 'focus on <OBJECT> — signal task completion', plus a single worked example. No padding, no explanation of concepts Claude already knows — every token earns its place, matching the top anchor. Not a 4 because there is no over-explanation left to trim.

Actionability

Gives fully executable, copy-paste-ready commands ('look around', 'focus on banana on banana tree') including a concrete ambiguity-recovery step ('respond with the option number (e.g., 0)') and a worked example with real observation text. Instruction-only guidance is this concrete and covers the common ambiguity case, matching the top anchor; a 4 would have minor gaps in the command details.

Workflow Clarity

This is a simple single-purpose skill under 50 lines, so the simple-skill exception applies: the sequence 'look around' (verification checkpoint) → 'focus on <OBJECT>' (execution) → numbered-option disambiguation (explicit error-recovery loop) is unambiguous and complete. Not a 4 because both the validation step and the failure-recovery path are explicitly present; the operation is non-destructive so no additional cap applies.

Progressive Disclosure

The body is well-organized into 'When to Use', 'Procedure', and 'Example' sections, and on its own is short enough to score 5 — but the bundle contains references/action_primer.md and references/trajectory_analysis.md with directly relevant supporting detail (action semantics, a real ambiguity transcript) that is never linked from SKILL.md. Scoring against the actual bundle structure, this is a minor organization gap, matching 'most content is appropriately placed; references mostly clear; minor organization gaps'. Not a 5 because existing reference files are orphaned rather than clearly signaled; not a 3 because the main body structure is clean and the skill functions without the references.

Specificity

Names the domain and a concrete action — 'Focuses on a specific target object to signal task completion' and "handles the 'focus on OBJ' action" — but these describe a single action rather than several, matching 'Names domain and 1-2 concrete actions, but not comprehensive'. Not a 4 because it does not list several distinct actions, and not a 2 because the action named is specific rather than generic.

Completeness

Explicitly answers both: what — 'Focuses on a specific target object to signal task completion... handles the 'focus on OBJ' action' — and when — 'Use when you have produced the required final object (like a grown banana) and need to formally complete the assigned task'. The 'Use when' clause is explicit with concrete trigger conditions, matching the top anchor; a 4 would require the 'when' to be less specific.

Trigger Term Quality

Includes some relevant natural phrases ('task completion', 'complete the assigned task', 'grown banana', 'focus on OBJ') but misses common variations and synonyms such as 'finish the task', 'mark done', 'objective complete', or 'goal achieved'. Not a 4 because keyword coverage has clear gaps; not a 2 because the terms present are genuinely natural rather than generic filler.

Distinctiveness Conflict Risk

The niche is mostly distinct — the 'focus on OBJ' environment action is unique to this skill — but the broad framing around 'task completion' and 'complete the assigned task' could overlap with other task-finalization skills, matching 'Mostly distinct; minor overlap risk'. Not a 5 because the completion framing is broadly applicable; not a 3 because the specific action reference anchors it clearly.
