The body is lean and assumes Claude's competence, with no over-explanation of what a 'focus' action or a conditional is; every section (When to Use, Procedure, Example) earns its place.

It gives concrete executable commands (`focus on <TARGET_OBJECT>`, `look around`) and a fully worked example with real values (63C > 50 → `focus on red box`), which is copy-paste ready for the ScienceWorld environment.

The four-step procedure is clearly sequenced with an explicit Verify step ("Confirm the focus action succeeded before proceeding") and a feedback loop ("If the focus action fails... use look around to verify the target object name"), matching the clear-sequence-with-validation anchor.

The body is well-organized into clear sections, but the bundled references/action_primer.md (which documents the very actions this skill uses) is present yet never linked or signaled from SKILL.md, matching 'references present but not clearly signaled'.

It names the concrete core action ("Executes a 'focus on OBJ' action on a specific object") and the conditional evaluation, but describes a single core action rather than the 'multiple specific concrete actions' the 3-anchor calls for, so it lands at 'names domain and some actions, not comprehensive'.

It explicitly states what the skill does ("Executes a 'focus on OBJ' action...") and gives an explicit 'Use when...' trigger clause ("Use when you have a measurement result and task instructions specify focusing on different objects..."), satisfying both what and when.

It uses relevant domain terms ("measurement result", "threshold", "focus", "colored boxes") but the phrasing is somewhat technical ("conditional evaluation", "meets a threshold") and lacks common natural variations, matching 'some relevant keywords but missing common variations'.

The trigger is highly specific to conditional measurement-to-focus tasks with colored-box branches, a clear niche unlikely to be confused with other skills.
