What it does

Scienceworld Circuit Builder is an agent skill from zjunlp/SkillNet. This skill constructs a simple electrical circuit by connecting components like batteries, wires, and light bulbs. Use when the agent needs to test electrical conductivity or create a functional circuit for an experiment. The input is a set of available components, and the output is a fully connected circuit ready for activation.

Its SKILL.md is about 830 tokens, which your agent loads only when the skill is triggered. The skill folder holds 2 other files, including reference files (for example `references/circuit_schematic.md`).

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

When your agent uses it

  • The agent needs to test electrical conductivity
  • Create a functional circuit for an experiment

What it can do on your machine

Read from SKILL.md and the folder at commit 3fcebf8. 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 Circuit Builder loads about 834 tokens when it runs, and up to ~851 if it reads all its reference files. Until then it costs about 90 tokens; SKILL.md has 432 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~90
When it runs · the whole SKILL.md, loaded when a task matches
~834
With references · SKILL.md plus every file in references/, read only if the agent opens them
~851

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 constructs a simple electrical circuit by connecting components like batteries, wires, and light bulbs. Use when the agent needs to test electrical conductivity or create a functional circuit for an experiment. The input is a set of available components, and the output is a fully connected circuit ready for activation.

Instructions

1. Objective

Your goal is to build a functional electrical circuit to test the conductivity of a target object (e.g., a metal pot). The circuit's success is indicated by a light bulb turning on.

2. Prerequisites & Setup

  • Location: You must be in the workshop. If not, teleport there.
  • Components: Ensure the following are present on the table:
    • A battery
    • A light bulb (e.g., blue light bulb)
    • At least two wires (e.g., orange, yellow, green)
    • The target object to test (e.g., metal pot)
    • A blue box (for conductive objects) and an orange box (for non-conductive objects)
  • Inventory: The target object must be in your inventory. If not, locate and pick it up.

3. Core Procedure

Follow these steps to construct the series circuit. Use the exact connect actions as shown.

  1. Place the Target Object: Drop the target object from your inventory onto the floor of the workshop.
  2. Connect Power Source:
    • connect battery anode to <Wire1> terminal 1 (e.g., orange wire)
    • connect battery cathode to <Wire2> terminal 1 (e.g., yellow wire)
  3. Connect Light Bulb:
    • connect <Wire1> terminal 2 to <LightBulb> cathode (e.g., blue light bulb)
    • connect <Wire3> terminal 2 to anode in <LightBulb> (e.g., green wire)
  4. Integrate Target Object into Circuit:
    • connect <TargetObject> terminal 1 to <Wire2> terminal 2
    • connect <TargetObject> terminal 2 to <Wire3> terminal 1

4. Testing & Conclusion

  1. Observe: After completing the connections, wait1 for 1-2 iterations.
  2. Check Result: look around. If the light bulb is on, the target object is electrically conductive.
  3. Final Action: Based on the result:
    • If conductive: move <TargetObject> to blue box
    • If non-conductive: move <TargetObject> to orange box

5. Key Principles

  • Circuit Logic: This builds a simple series circuit: Battery -> Wire1 -> Light Bulb -> Wire3 -> Target Object -> Wire2 -> Battery.
  • Action Precision: Use the exact object names and connection points (anode, cathode, terminal 1/2) as observed in the environment.
  • Error Handling: If a component is missing, examine the room (look around) to identify available substitutes before proceeding.

6. Example

Task: Test whether a metal pot is electrically conductive.

  1. teleport to workshop
  2. pick up metal pot
  3. connect battery anode to orange wire terminal 1
  4. connect battery cathode to yellow wire terminal 1
  5. connect orange wire terminal 2 to blue light bulb cathode
  6. connect green wire terminal 2 to anode in blue light bulb
  7. connect metal pot terminal 1 to yellow wire terminal 2
  8. connect metal pot terminal 2 to green wire terminal 1
  9. wait1 — observe if the light bulb turns on
  10. Light bulb is on → move metal pot to blue box (conductive)
