What it does

Scienceworld Object Focuser is an agent skill from zjunlp/SkillNet. 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.

Its SKILL.md is about 570 tokens, which your agent loads only when the skill is triggered. The skill folder holds 2 other files, including reference files (for example `references/usage_examples.md`).

The repository describes itself as: Create, Evaluate, and Connect AI Skills. The licence is MIT.

When your agent uses it

  • 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
  • Using the object in ScienceWorld tasks

Example prompts

  • “focus on OBJ”
  • “/scienceworld-object-focuser”

Workflow steps

3 steps, taken from the first numbered list in SKILL.md.

  1. Identify the Target: From your observation (look around, examine), determine the exact name of the object you intend to use for the task.
  2. Execute Focus: Use the action: focus on .
  3. Proceed: After receiving a confirmation observation, continue with the next step in your plan (e.g., pick up , move to ...).

What it can do on your machine

Read from SKILL.md and the folder at commit c527136. It shows what the files ask for, not the result of running them.

  • Tool permissions

    Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.

    From allowed-tools in the SKILL.md frontmatter.

  • Runs code

    No scripts in the folder and no shell commands in SKILL.md.

    From the folder's file list and the shell code blocks in SKILL.md.

  • Network

    No URLs in SKILL.md.

    From URLs in SKILL.md, links to its own repository left out.

  • Credentials

    Names no API keys, tokens, secrets or passwords.

    From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

Scienceworld Object Focuser loads about 574 tokens when it runs, and up to ~1k if it reads all its reference files. Until then it costs about 103 tokens; SKILL.md has 278 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~103
When it runs · the whole SKILL.md, loaded when a task matches
~574
With references · SKILL.md plus every file in references/, read only if the agent opens them
~1k

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Safety

Auto-check passed

The automated check found no risky patterns in SKILL.md.

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

description
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.

Skill: Object Focuser

Purpose

Use this skill to formally select a target object in the ScienceWorld environment. The focus on action signals your intent to the task system and is often a prerequisite for subsequent manipulation steps like pick up or move.

When to Use

  • After you have identified an object that matches the task's criteria (e.g., "a living thing", "a conductive material").
  • Before you attempt to pick up, move, or use that object as part of the task sequence.
  • When the task trajectory or environment feedback suggests an object needs to be "focused on" to proceed.

Core Instruction

  1. Identify the Target: From your observation (look around, examine), determine the exact name of the object you intend to use for the task.
  2. Execute Focus: Use the action: focus on <OBJECT_NAME>.
    • Replace <OBJECT_NAME> with the precise noun phrase from the environment (e.g., dove egg, copper wire, beaker).
  3. Proceed: After receiving a confirmation observation, continue with the next step in your plan (e.g., pick up <OBJECT_NAME>, move <OBJECT_NAME> to ...).

Key Considerations

  • Object Naming: Use the name exactly as it appears in observations. The system is case-sensitive and expects the full descriptor (e.g., "dove egg", not just "dove" or "egg").
  • Timing: Focus is typically performed after exploration/identification and before the main manipulation action.
  • Task Logic: This action is a procedural formality within ScienceWorld. It does not change the object's state but informs the task tracker of your selected target.

Example

Task: Focus on a dove egg before picking it up for a biology task.

  1. look around — observe: "a dove egg on the table"
  2. focus on dove egg
  3. Confirmation received → proceed with pick up dove egg.
