scienceworld-object-focuser

This skill selects and focuses on a specific object to signal task intent or prepare it for manipulation. Use when you have identified a target object that meets task criteria (e.g., a living thing) and need to formally select it before performing actions like moving or using the object in ScienceWorld tasks. The skill uses the 'focus on OBJ' action, taking the object name as input.

85%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.

The body is a tight, fully actionable instruction for a simple single-action skill, with an explicit confirmation checkpoint in its workflow. Its one real weakness is navigation: the bundled references/usage_examples.md is orphaned, with no pointer from the body, so valuable patterns and anti-patterns are undiscoverable.

Suggestions

Add a clearly signaled link to the bundled reference, e.g., a '## More Examples' section pointing to [usage_examples.md](references/usage_examples.md), so the bundle's patterns and anti-patterns are discoverable.

Fold the most critical anti-patterns (e.g., never focus on substances like air/water, always use the full object name) into the body's Key Considerations, since they currently live only in the unreferenced file.

Trim the small overlap between the Purpose and When to Use sections to push conciseness toward the top anchor.

Dimension	Reasoning	Score
Conciseness	The body is lean, explains nothing Claude already knows, and adds genuinely non-obvious details (case-sensitive naming, timing, that focus does not change object state). Not 5 because the 'focus on' mechanics are restated across Purpose, When to Use, and Core Instruction, leaving minor trimming opportunities.	4 / 5
Actionability	Provides the exact executable command `focus on <OBJECT_NAME>` with precise noun-phrase examples (`dove egg`, `copper wire`, `beaker`) and a worked example trace from `look around` through confirmation. This is copy-paste ready and covers the common cases, matching the top anchor.	5 / 5
Workflow Clarity	The Identify -> Execute Focus -> Proceed sequence is unambiguous and includes an explicit validation checkpoint ("After receiving a confirmation observation, continue"), and the simple-skill exception applies since this is a single-purpose skill under 50 lines with no destructive or batch operations. Not 4: the confirmation gate is explicit rather than implicit.	5 / 5
Progressive Disclosure	The body itself is well-organized with clear sections, but the bundle contains references/usage_examples.md (with useful common patterns and anti-patterns) that is never linked or mentioned in the body. Per the rubric's bundle-structure guideline this is a reference that is present but not clearly signaled, matching anchor 3 rather than 4.	3 / 5

Description

82%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 description that clearly communicates a single concrete capability with an explicit and detailed 'Use when' clause. Its only deductions are the second-person voice in the trigger clause (penalized under the rubric's specificity rule) and incomplete synonym coverage in trigger terms.

Suggestions

Rewrite the trigger clause in third person (e.g., "Use when a target object meeting task criteria has been identified and must be formally selected before moving or using it in ScienceWorld tasks") to avoid the second-person voice penalty.

Add one or two natural trigger synonyms such as "select" or "target object" to broaden keyword coverage for invocation.

Dimension	Reasoning	Score
Specificity	Names the domain and the concrete action with exact syntax ("uses the 'focus on OBJ' action, taking the object name as input"), which fits anchor 4, but the second-person phrasing "Use when you have identified..." triggers the rubric's -1 voice penalty. It is not anchor 2 because the actions described are specific rather than generic.	3 / 5
Completeness	Explicitly answers what ("selects and focuses on a specific object to signal task intent or prepare it for manipulation" plus the exact 'focus on OBJ' action) and when ("Use when you have identified a target object that meets task criteria (e.g., a living thing) and need to formally select it before performing actions like moving or using the object"). Both are concrete with explicit trigger conditions, matching the top anchor.	5 / 5
Trigger Term Quality	Includes natural domain terms users would say: "object", "focus on", "living thing", "moving", "ScienceWorld", "task criteria". Not 5 because common synonyms and variations (e.g., "select", "target") are absent; not 3 because the keywords present are specific and directly relevant rather than partially missing.	4 / 5
Distinctiveness Conflict Risk	Scoped to ScienceWorld's specific 'focus on OBJ' action with task-criteria triggers, giving it a clear niche with minimal overlap risk against other skills. Not 4: no meaningful overlap with even closely related skills was identified.	5 / 5
