scienceworld-substance-cooler

This skill initiates the cooling of a substance by moving it into a cooling appliance like a freezer. Use when a task requires lowering the temperature of a specific material to observe phase changes. The skill takes the substance (often in a container) and the target appliance as inputs, using the 'move OBJ to OBJ' action. It outputs confirmation of the new location.

Quality

Content

78%Weight 40%Scale 1-5

Reviews the quality of instructions and guidance provided to agents. Good implementation is clear, handles edge cases, and produces reliable results.

A concise, highly actionable body with a clear verify-checked workflow for a simple single-purpose skill. Its main weakness is navigation: the existing phase_change_protocol.md reference is not linked from the body, leaving supplementary workflow/error content undiscoverable.

Suggestions

Add a one-line pointer to the bundled reference, e.g. 'See [phase_change_protocol.md](references/phase_change_protocol.md) for the full monitoring workflow and error handling.' under Important Notes.

Surface the key error-recovery cue (e.g. 'If move fails, ensure the appliance door is open') inline so the feedback loop is visible without following the reference.

Trim the prerequisite note about the door/trajectory, which restates environment assumptions Claude can observe directly.

Dimension	Reasoning	Score
Conciseness	The body is lean and assumes Claude's competence (no explanation of what a freezer or phase change is), with only minor trimmable redundancy in the Important Notes (e.g., the door/prerequisite note restates trajectory assumptions).	4 / 5
Actionability	Provides concrete, copy-paste-ready command templates (`move <SUBSTANCE_CONTAINER> to <APPLIANCE>`, `look around`, `look at <APPLIANCE>`) plus a fully worked trajectory example with literal object names, covering the common case.	5 / 5
Workflow Clarity	Clear three-step sequence (Locate → Execute Move → Verify) with an explicit verification checkpoint, but the body lacks an error-recovery feedback loop (that material lives only in the reference file), so it stops just short of anchor 5.	4 / 5
Progressive Disclosure	The body is well-sectioned and concise, but it never links to the bundled references/phase_change_protocol.md even though that file contains the full monitoring workflow and error handling that the body alludes to ('Subsequent skills or actions... are required'), so a reference is present but not signaled.	3 / 5

Description

87%Weight 40%Scale 1-5

Based on the skill's description, can an agent find and select it at the right time? Clear, specific descriptions lead to better discovery.

A strong, concrete description that clearly states the action, inputs, outputs, and an explicit Use-when trigger for a narrow niche. It is only slightly limited by single-action scope and a few missing synonyms.

Dimension	Reasoning	Score
Specificity	Names the concrete action ('moving it into a cooling appliance like a freezer', 'using the move OBJ to OBJ action'), inputs (substance/container + appliance), and output (confirmation of new location), but it is essentially a single core action rather than multiple distinct capabilities, so it stops short of the comprehensive multi-action anchor 5.	4 / 5
Completeness	Explicitly answers both what ('initiates the cooling of a substance by moving it into a cooling appliance... using the move OBJ to OBJ action') and when ('Use when a task requires lowering the temperature of a specific material to observe phase changes'), matching the anchor for clear concrete triggers on both halves.	5 / 5
Trigger Term Quality	Includes natural terms a user would say for this domain ('cooling', 'lowering the temperature', 'phase changes', 'freezer'), but misses common synonyms such as 'freeze/freezing' or 'chill', landing at good-but-not-comprehensive coverage.	4 / 5
Distinctiveness Conflict Risk	Occupies a clear narrow niche (cooling a substance via move-to-appliance in ScienceWorld) with distinct cooling/phase-change triggers and minimal overlap risk with sibling skills.	5 / 5
