What it does

Scienceworld Object Locator is an agent skill from zjunlp/SkillNet. Searches for a specific target object across multiple rooms by systematically teleporting to likely locations and examining each room. Use this skill when you need to find an object whose exact location is unknown. Iterates through candidate rooms using teleport and look around, checks for the object, and continues until found, returning the object's location.

Its SKILL.md is about 690 tokens, which your agent loads only when the skill is triggered. The skill folder holds 4 other files, including reference files (for example `references/action_guide.md`, `references/action_primer.md` and `references/example_trajectory_breakdown.md`).

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

When your agent uses it

  • You need to find an object whose exact location is unknown

Example prompts

  • “Use the scienceworld-object-locator skill to search for a specific target object across multiple rooms by systematically teleporting to likely…”
  • “/scienceworld-object-locator”

Workflow steps

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

  1. Initialize: Receive the target object name.
  2. Plan Search Order: Determine the sequence of rooms to search. Use the provided prioritize_rooms.py script to generate an optimal search…
  3. Execute Search Loop
  4. Output: Report the room where the object was found. If the object is not found after searching all candidate rooms, report this failure.

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 Locator loads about 686 tokens when it runs, and up to ~1.7k if it reads all its reference files. Until then it costs about 98 tokens; SKILL.md has 356 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~98
When it runs · the whole SKILL.md, loaded when a task matches
~686
With references · SKILL.md plus every file in references/, read only if the agent opens them
~1.7k

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
Searches for a specific target object across multiple rooms by systematically teleporting to likely locations and examining each room. Use this skill when you need to find an object whose exact location is unknown. Iterates through candidate rooms using teleport and look around, checks for the object, and continues until found, returning the object's location.

Instructions

Purpose

Locate a specific target object within the ScienceWorld environment when its location is unknown.

Inputs

  • Target Object: The name of the object to find (e.g., "thermometer", "metal fork").
  • Candidate Rooms (Optional): A list of room names to search. If not provided, the skill will use a default priority list based on common object locations.

Core Process

  1. Initialize: Receive the target object name.
  2. Plan Search Order: Determine the sequence of rooms to search. Use the provided prioritize_rooms.py script to generate an optimal search order based on the target object.
  3. Execute Search Loop: a. Teleport to the next room in the search order. b. Use the look around action to observe the room's contents. c. Parse the observation to check for the presence of the target object. d. If the object is found, stop the search and output its location. e. If the object is not found, proceed to the next room.
  4. Output: Report the room where the object was found. If the object is not found after searching all candidate rooms, report this failure.

Key Actions

  • teleport to <ROOM_NAME>
  • look around
  • examine <OBJECT> (if more detail is needed to confirm identity)
  • pick up <OBJECT> (if the goal is to acquire the object, not just locate it)

Example

Task: Find the thermometer in the environment.

  1. teleport to kitchen
  2. look around — no thermometer found
  3. teleport to workshop
  4. look around — observation includes "a thermometer, currently reading a temperature of 10 degrees celsius"
  5. Thermometer located in workshop. pick up thermometer if needed.

Notes & Best Practices

  • Efficiency: Always look around immediately after teleporting to get the full room state.
  • Parsing: Observations list objects after "you see:". Check this list for the target object's name.
  • Confirmation: If an object's name is ambiguous (e.g., "fork" could be "metal fork" or "plastic fork"), use examine to get a detailed description.
  • Inventory: If the task requires using the object, remember to pick it up after finding it.
  • Error Handling: If an object is not in its most likely room, the systematic search will eventually find it. Do not give up after the first few rooms.
