Conciseness

The body is lean and assumes agent competence, with concrete commands instead of concept explanations. Minor trimming is possible: the Trigger line duplicates the frontmatter description almost verbatim and the '**Result:**' line restates what the example already shows, which fits the 'efficient with minor over-explanation' anchor 4 rather than the every-token-earns-its-place anchor 5.

Actionability

Fully executable action templates ('go to {recep}', 'put {obj} in/on {recep}'), concrete observation-parsing rules ('On the {recep}, you see...', 'you see nothing.'), and a complete worked trajectory covering the common case make the guidance copy-paste ready, matching the top anchor.

Workflow Clarity

The four-step procedure is clearly sequenced with explicit per-iteration checkpoints ('Carefully read the observation after each go to action') and a concrete error-recovery feedback loop ('If an action fails ("Nothing happened"), re-evaluate your target and try a different receptacle'), matching the anchor requiring validation steps and feedback loops. The operations are non-destructive, so no batch/destructive cap applies.

Progressive Disclosure

The ~40-line body is well organized into sections with a single clearly signaled one-level-deep reference (references/example_trajectory.md) that exists in the bundle and is described accurately ('a detailed example including handling object pre-cleaning and sequential shelf evaluation'). This matches the simple-skill pattern where concise body plus well-signaled shallow references earns the top anchor.

Specificity

The description lists several concrete actions ('Searches for a suitable empty or appropriately occupied receptacle', 'Examines candidate receptacles by navigating to and inspecting each one') in third person, matching the several-specific-actions anchor. 'Meets the placement criteria' is slightly abstract and coverage of the evaluation criteria is implied rather than enumerated, keeping it below the comprehensive anchor 5.

Completeness

It explicitly answers both what ('Searches for a suitable empty or appropriately occupied receptacle... Examines candidate receptacles by navigating to and inspecting each one') and when ('Use when you are holding an object that needs to be stored or placed and must find a receptacle') with concrete trigger phrases, matching the top anchor exactly.

Trigger Term Quality

Natural phrases like 'Use when you are holding an object that needs to be stored or placed' plus concrete nouns ('shelf', 'table', 'receptacle', 'empty') give good keyword coverage. It lacks common synonyms or variations a user might say (e.g., 'put away', 'find a spot for'), so it does not reach the comprehensive anchor 5.

Distinctiveness Conflict Risk

The trigger condition (holding an object that must be placed in a suitable receptacle) carves out a clear niche with minimal conflict risk against unrelated skills. Minor overlap remains with general object-placement or cleaning skills, so it sits at anchor 4 rather than the minimal-conflict anchor 5.
