Conciseness

The body is lean and well-sectioned ("When to Use", "Core Procedure", "Key Principles", worked example) with no explanations of concepts Claude already knows. Minor redundancy — the opening line restates the frontmatter description and "Container Verification" overlaps step 4's context check — keeps it at anchor 4 rather than the every-token-earns-its-place anchor 5.

Actionability

Guidance is fully executable for an instruction-only skill: the exact action template "move OBJ to CONTAINER", the "look around" verification command, and a complete worked example ending in the copy-paste-ready "move metal pot to blue box" covering the common conductivity case. This matches anchor 5's concrete commands plus common-case examples.

Workflow Clarity

The "Core Procedure" gives a clear 4-step sequence (Verify Context → Confirm Test Result → Apply Rule → Execute Archive) with two explicit validation checkpoints: "Observe the final state of your experimental apparatus to definitively determine the test outcome" and "visually confirm the target container exists in the room (use `look around` if uncertain)". This is a single low-risk, non-destructive operation, so the missing feedback-loop requirement does not cap it; it matches anchor 5 via the simple-skill exception.

Progressive Disclosure

The body is under 50 lines and well-organized, but it directs the reader to "the bundled script `scripts/conductivity_test.py`" and no scripts/ directory (or any bundle file) exists in the skill — the single external reference is dangling. Structure is present, yet the one-level-deep navigation it claims does not actually resolve, which fits anchor 3 (references present but not working/organized properly) rather than anchor 4's 'minor organization gaps'.

Specificity

"Places an object into a designated container (like a colored box) based on a test outcome" plus "The input is the object and the rule, and the output is the object moved to the correct container" names the domain and one concrete action with I/O, matching the 1-2-concrete-actions anchor. It does not list several specific actions, so it falls short of anchor 4; it is well above the generic anchor 2 because the action and input/output are concrete.

Completeness

Both parts are present: a clear 'what' ("Places an object into a designated container... based on a test outcome" with input and output) and an explicit 'when' ("It should be triggered when the agent needs to finalize a task by storing an object according to a rule"). The 'when' clause is explicit but somewhat abstract — it describes the condition rather than concrete trigger phrases a user would say — so it matches anchor 4 rather than anchor 5.

Trigger Term Quality

Terms like "conductive → blue box, non-conductive → orange box", "finalize a task", "storing an object", and "test outcome" are natural to the domain and would appear in the triggering context. A few common phrasings (e.g., "sort", "archive", "property test") are missing, which keeps it below the comprehensive-synonyms anchor 5 but clearly above anchor 3's partial coverage.

Distinctiveness Conflict Risk

The description carves out a clear niche — archiving tested objects into color-coded containers by a conductivity-style rule ("conductive → blue box, non-conductive → orange box") — that no general-purpose skill would plausibly claim. Triggers are distinct and specific, matching the minimal-conflict anchor 5.
