scienceworld-substance-preparator

Use when you need to transfer a target substance into an appropriate container for processing (e.g., a pot for heating, a beaker for mixing). Trigger after acquiring the substance and before setting up an apparatus. Selects a suitable empty container and moves the substance into it.

Quality

Content

100%

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

The body is a tight, fully actionable instruction skill: concrete commands, a numbered procedure with an explicit verification step, and a worked example, supported by a single real one-level reference. It respects token budget while remaining copy-paste ready.

Dimension	Reasoning	Score
Conciseness	Lean and efficient across ~40 lines with no padding or explanations of concepts Claude already knows; every section (Purpose, When to Use, Core Procedure, Key Considerations, Example) earns its place.	3 / 3
Actionability	Provides concrete executable commands (`move [SUBSTANCE] to [CONTAINER]`, `examine`, `look around`) and a fully worked example with exact inputs and expected output, leaving nothing abstract.	3 / 3
Workflow Clarity	A clearly sequenced 5-step procedure includes an explicit Verify step, and the worked example ends by confirming the transfer succeeded; the operation is non-destructive so the feedback loop present is sufficient.	3 / 3
Progressive Disclosure	Well-organized sections with a single one-level-deep reference (`common_containers.md`) that actually exists and is signaled inline; for a simple sub-50-line skill this structure is appropriate.	3 / 3
	Total	12 / 12 Passed

Description

85%

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

The description is specific, complete, and clearly distinct, with an explicit 'Use when' trigger and concrete actions. Its only weak spot is trigger-term naturalness: it leans on task-domain jargon ('substance', 'apparatus') rather than language a user would naturally say.

Dimension	Reasoning	Score
Specificity	Lists multiple concrete actions — 'transfer a target substance into an appropriate container', 'Selects a suitable empty container and moves the substance into it' — with concrete examples (a pot for heating, a beaker for mixing).	3 / 3
Completeness	Explicitly answers both what (select an empty container and move the substance into it) and when ('Use when you need to transfer... Trigger after acquiring the substance and before setting up an apparatus').	3 / 3
Trigger Term Quality	It opens with a natural 'Use when you need to transfer...' trigger, but the dominant terms ('substance', 'apparatus', 'target substance') are domain jargon rather than the natural phrasings a user would say, and it lacks common variations.	2 / 3
Distinctiveness Conflict Risk	It carves a clear niche — transferring a substance into a process-appropriate container as a preparation step — with a distinct trigger unlikely to fire for unrelated skills.	3 / 3
	Total	11 / 12 Passed
