What it does

Scienceworld Tool Fetcher is an agent skill from zjunlp/SkillNet. This skill locates and picks up a specified tool or instrument from the environment. It should be triggered when a task requires a specific tool (e.g., thermometer, stopwatch) for measurement or manipulation. The skill identifies the tool's location via observation and executes a pick-up action, moving the tool to inventory.

Its SKILL.md is about 580 tokens, which your agent loads only when the skill is triggered. The skill folder holds 3 other files, including reference files (for example `references/environment_actions.md` and `references/trajectory_analysis.md`).

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

Workflow steps

4 steps, taken from the step headings in SKILL.md.

  1. Identify the Target Tool
  2. Locate the Tool via Exploration
  3. Execute the Pick-up
  4. Post-Action Verification (Optional)

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 Tool Fetcher loads about 584 tokens when it runs, and up to ~1.5k if it reads all its reference files. Until then it costs about 88 tokens; SKILL.md has 290 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~88
When it runs · the whole SKILL.md, loaded when a task matches
~584
With references · SKILL.md plus every file in references/, read only if the agent opens them
~1.5k

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 locates and picks up a specified tool or instrument from the environment. It should be triggered when a task requires a specific tool (e.g., thermometer, stopwatch) for measurement or manipulation. The skill identifies the tool's location via observation and executes a pick-up action, moving the tool to inventory.

Instructions

Primary Goal: Locate a specified tool and move it to your inventory.

1. Identify the Target Tool

  • The required tool will be specified in the user's task or request (e.g., "thermometer", "stopwatch", "lighter").
  • Confirm the exact name of the tool object.

2. Locate the Tool via Exploration

  • If you are not in the correct room, use teleport to [ROOM_NAME] to go to the most likely location (e.g., kitchen, workshop).
  • Use look around to survey the current room.
  • Scan the observation for the target tool name. It may be:
    • Listed directly in the room description (e.g., "a thermometer").
    • Inside an open container (e.g., "a fridge. In the fridge is: chocolate, a wood cup...").
  • If the tool is not immediately visible, examine likely containers using look at [CONTAINER] (e.g., look at counter, look at cupboard).

3. Execute the Pick-up

  • Once the tool is located, execute the action: pick up [TOOL_NAME].
  • Example: pick up thermometer.
  • Verify the action was successful by checking the observation for confirmation (e.g., "You move the thermometer to the inventory.").

4. Post-Action Verification (Optional)

  • If required by the broader task, you may perform a secondary action to signal readiness, such as focus on [TOOL_NAME] in inventory.

Key Constraints & Notes

  • Containers are Open: All containers are pre-opened. Do not use open or close actions.
  • Direct Action: Proceed directly to pick up. Do not attempt to move the tool to an intermediate location first.
  • Tool Not Found: If the tool is not in the initial room, systematically teleport to other relevant rooms and repeat the look around search pattern.
  • Single Tool: This skill fetches one specified tool. For multiple tools, trigger the skill sequentially.

Output: The target tool will be in your inventory, ready for use in subsequent task steps.
