The body is lean and assumes Claude's competence—no concept-explaining fluff, organized into tight sections; the minor overlap between 'Expected Output & Interpretation' and 'Example from Trajectory' is light reinforcement rather than padding, so it sits at the 'lean and efficient' anchor and not the 'could be tightened' score-2 level.

Gives a concrete, copy-paste-ready command template ('look at <CONTAINER_NAME>') plus a worked action/observation example; for a text-game action skill this is fully executable guidance matching the 'fully executable…copy-paste ready' anchor rather than the pseudocode score-2 anchor.

Sequences a multi-step process ('move → look at → activate → look at → use') and includes explicit recovery checkpoints (verify name via 'look around'/'examine', 'open' a closed door before use); inspection is non-destructive so the destructive-operation cap does not apply, placing it at the 'clear sequence with explicit validation steps' anchor.

A bundle file references/container_inspection_examples.md exists but is never linked or signaled from the body and is itself truncated (ending at 'Observation:' with no content), while example content sits inline—matching the 'references present but not clearly signaled; content that should be separate is inline' anchor rather than the well-signaled score-3 anchor.

Lists multiple concrete actions ('Inspects the contents…using the look at action', 'verify what is inside', 'monitor the state of contents', 'confirm that a placement or process step succeeded', 'Returns a detailed list of contents and their states'), matching the 'lists multiple specific concrete actions' anchor rather than the single-domain score-2 anchor.

Explicitly answers both 'what' ('Inspects the contents…Returns a detailed list of contents and their states') and 'when' ('Use this skill when you need to verify…monitor…or confirm…'), matching the 'clearly answers both what AND when with explicit triggers' anchor; it is not score 2 because the trigger clause is explicit, not implied.

Natural user phrasings are well covered ('verify what is inside a container', 'checking if lead is in the blast furnace', 'monitor the state of contents', 'solid vs. liquid phase changes'), matching the good-coverage anchor; it is not the score-2 'some relevant keywords but missing common variations' level.

It carves a clear niche (container/device inspection via the 'look at' action in a ScienceWorld-style environment) with distinct triggers unlikely to fire for unrelated skills, matching the 'clear niche with distinct triggers' anchor rather than the overlapping score-2 anchor.
