The body is under 20 lines with no re-explanation of concepts Claude already knows; sections are tight and every token earns its place, matching the lean anchor 3.

It gives concrete, executable environment commands ('look around', 'focus on <OBJECT>', respond with '0') plus a fully worked 'Grow a banana' example, satisfying the copy-paste-ready anchor 3 for an instruction-only skill.

The procedure is a clear sequence with a verification checkpoint ('look around — confirm the target object is visible') and an explicit ambiguity feedback loop; for a simple single-task skill this meets anchor 3.

Sections are well organized, but two bundle files exist in references/ (action_primer.md, trajectory_analysis.md) and neither is linked or signaled from the body, fitting the 'references present but not clearly signaled' anchor 2 rather than the well-signaled anchor 3.

Quotes 'Focuses on a specific target object to signal task completion' and 'handles the 'focus on OBJ' action' name the domain and a concrete action, but as a single-action skill it does not list multiple distinct concrete actions required for a 3.

It states what the skill does ('signal task completion' via 'focus on OBJ') and gives an explicit 'Use when...' trigger for when to invoke it, satisfying both halves required for a 3.

The 'Use when you have produced the required final object... and need to formally complete the assigned task' clause offers relevant triggers, but coverage of natural phrasings is narrow and misses common variations, matching anchor 2 rather than the broad coverage of anchor 3.

The narrow niche of formally signaling task completion in this simulation environment has distinct triggers and is unlikely to overlap with other skills, matching the anchor 3 example.
