The body is lean (~30 lines) with tight sections (Purpose, Trigger Conditions, Core Action, Workflow, Notes, Example) and no padding or explanation of concepts Claude already knows; nearly every token earns its place despite a minor restatement of the open-container precondition.

Gives the exact action format ("pick up <ITEM>" with <ITEM> as the observed object name), the precise expected observation string, and a worked example ("pick up avocado seed"), making it copy-paste ready for the environment.

Sequences Verify Context -> Execute Transfer -> Confirm Success with an explicit validation checkpoint (expected observation) and an error-recovery fallback to troubleshooting; for this simple single-action skill the workflow is clear and well-organized.

The overview is clear and troubleshooting content is correctly split into references/execution_examples.md, but the body only says "consult the troubleshooting guide" without linking the actual file path, so the one-level-deep reference is present but not clearly signaled.

Names a concrete action ("using the 'pick up' action"), the object transfer to inventory, and the expected output confirmation rather than vague language. For a single-action skill this level of concreteness matches the 'multiple specific concrete actions' anchor.

Explicitly answers what ("retrieves a specified item from a container by using the 'pick up' action") and when ("It should be triggered when the agent has identified a needed item inside an open container"), an explicit trigger clause equivalent to 'Use when...', so it is not capped at 2.

Includes natural domain terms users/agents encounter ("item", "container", "jar, box, or hive", "inventory", "pick up") with concrete container examples, giving good coverage of phrasing a caller would actually use.

Targets a narrow, well-scoped niche (item inside an open, accessible container transferred to inventory) with distinct triggers, making conflict with unrelated skills unlikely.
