scienceworld-object-selector
Use when the agent needs to choose a specific object from multiple candidates in the environment based on task criteria such as object type (non-living thing, electrical component, container), properties, or category. This skill surveys visible objects with "look around", evaluates each against the task requirements, selects the most suitable candidate, and signals intent with "focus on [OBJECT]".

Same command for any agent — swap --agent for codex, cursor, copilot.

# Skill: scienceworld-object-selector ## Purpose Identify and select the correct object from visible candidates in the ScienceWorld environment based on task-defined criteria (e.g., "non-living thing", "electrical component", "container"), then signal intent with a `focus on` action. ## When to Use - When a task requires choosing a specific type of object from multiple visible options - When the agent must classify objects by property (living/non-living, material type, function) to select one - When the task instructs finding and interacting with a particular category of object ## Workflow 1. **Survey the environment** -- Use `look around` to list all visible objects in the current location. 2. **Evaluate candidates** -- For each visible object, determine if it matches the task criteria. Exclude target containers (e.g., destination boxes) and fixed furniture from candidates. 3. **Select the best match** -- Choose the first suitable, portable object unless the task specifies a preference (e.g., "largest", "closest"). 4. **Signal intent** -- Execute `focus on [OBJECT]` to confirm selection. 5. **Execute the task action** -- Proceed with the required action (e.g., `pick up`, `move`, `

How do I install it?
Run `npx skills add zjunlp/SkillNet --skill scienceworld-object-selector --agent claude-code` — it drops the skill into your project so the agent can pick it up. Swap the --agent value for codex, cursor or copilot if you use one of those.
Where does this skill come from?
From zjunlp/SkillNet, a repository with 1,117 stars. We read it straight from the repository tree rather than a submitted listing, so what you see here is what is actually published.
Is a popular skill a good skill?
Not necessarily. Stars measure attention, not adoption — a repository can trend for a week and be abandoned. That is why we show the weekly change from our own snapshots next to the total, instead of a single flattering number.
