Conciseness

The body is lean and assumes competence ("Clean an object you are holding using a sinkbasin") with no padding or explanation of known concepts. It misses 5 because the clean-state outcome is restated in three places (Workflow step 3, the Example's Result, and the Post-Condition section) and the Action Format section duplicates the command already shown in the workflow.

Actionability

Fully executable, copy-paste-ready commands throughout: `go to sinkbasin 1`, `clean {object} with sinkbasin 1`, the general format `clean {obj} with {recep}` with a concrete instance, a complete worked Thought/Action/Observation example, and specific error-recovery checks. This matches the anchor for executable guidance covering the common cases.

Workflow Clarity

A simple single-purpose skill with an unambiguous action, satisfying the simple-skill exception. The sequence (navigate → clean → proceed) includes an explicit validation checkpoint ("verify observation confirms 'You clean the {object}'") and an error-recovery feedback loop for the "Nothing happened" failure mode, matching the anchor with explicit validation and error recovery.

Progressive Disclosure

The body itself has clear, well-organized sections, but the bundle contains references/trajectory_analysis.md and references/troubleshooting.md that are never linked or signaled anywhere in the body — the Error Recovery section instead duplicates troubleshooting.md's content inline. This matches the anchor for references present but not clearly signaled with content that should be separate left inline; it is not 4 because the orphaned bundle files are a real navigation gap, not a minor one, and not 2 because the body's own structure is good and nothing is deeply nested.

Specificity

Lists several concrete actions — "Cleans a specified object using an appropriate cleaning receptacle", "Navigates to the cleaning location", "performs the clean action", and "confirms the object is now clean" — matching the several-specific-actions anchor. It falls short of 5 because "performs the clean action" restates the opening rather than adding a distinct capability, leaving minor gaps in coverage.

Completeness

Explicitly answers both what ("Cleans a specified object using an appropriate cleaning receptacle... Navigates... performs the clean action, and confirms") and when with a concrete "Use when" clause containing literal trigger phrases ("clean potato", "wash apple"). This directly matches the anchor 5 example structure; a missing or weaker trigger clause would place it at 3-4.

Trigger Term Quality

Natural trigger phrases like "clean potato" and "wash apple" capture the two most common synonyms users would say, plus "task requires an object to be in a clean state". Not 5 because other natural variations (e.g., rinse, scrub) and any command-form triggers are absent; not 3 because the quoted example phrases are exactly what a user would say.

Distinctiveness Conflict Risk

Occupies a clear niche (cleaning a held object at a sinkbasin) with distinct trigger phrasing unlikely to fire for sibling skills like heating, cooling, or placing objects. Anchor 4 would require identifiable overlap with closely related skills, and none is evident from the description itself.
