What it does

Alfworld Appliance Preparer is an agent skill from zjunlp/SkillNet. Prepares a household appliance (microwave, oven, toaster, fridge) for use by ensuring it is in the correct open/closed state. Use when the agent needs to heat, cool, or cook an item and must first open or close the appliance before placing an object inside. Takes an appliance identifier as input and outputs a confirmation that the appliance is ready for the next action.

Its SKILL.md is about 610 tokens, which your agent loads only when the skill is triggered. The skill folder holds 2 other files, including reference files (for example `references/trajectory_example.md`).

It sits in Agent Workflows. The repository describes itself as: Create, Evaluate, and Connect AI Skills. The licence is MIT.

When your agent uses it

  • The agent needs to heat
  • Cook an item and must first open
  • Close the appliance before placing an object inside

Example prompts

  • “Use the alfworld-appliance-preparer skill to prepare a household appliance (microwave, oven, toaster, fridge) for use by ensuring it is in the…”
  • “/alfworld-appliance-preparer”

Workflow steps

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

  1. Navigate to the Appliance: First, go to the location of the target appliance.
  2. Check State & Prepare: Determine if the appliance needs to be opened or closed based on the intended subsequent action. The standard rule is
  3. Confirm Readiness: The skill is complete when the appliance is in the correct state, confirmed by an observation from the environment…

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

    Shell commands in SKILL.md call:

    • go

    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

Alfworld Appliance Preparer loads about 611 tokens when it runs, and up to ~956 if it reads all its reference files. Until then it costs about 100 tokens; SKILL.md has 294 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~100
When it runs · the whole SKILL.md, loaded when a task matches
~611
With references · SKILL.md plus every file in references/, read only if the agent opens them
~956

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
Prepares a household appliance (microwave, oven, toaster, fridge) for use by ensuring it is in the correct open/closed state. Use when the agent needs to heat, cool, or cook an item and must first open or close the appliance before placing an object inside. Takes an appliance identifier as input and outputs a confirmation that the appliance is ready for the next action.

Instructions

Goal

Prepare a specified household appliance for immediate use by ensuring it is in the correct open or closed state. This is a prerequisite step before performing actions like heat, cool, or toggle with the appliance.

Input

  • appliance_identifier: The name of the appliance to prepare (e.g., microwave 1, toaster 1, fridge 1).

Core Logic

  1. Navigate to the Appliance: First, go to the location of the target appliance.
  2. Check State & Prepare: Determine if the appliance needs to be opened or closed based on the intended subsequent action. The standard rule is:
    • For appliances used to contain items for processing (e.g., microwave, oven, fridge), they typically need to be open to receive the item.
    • Use the open {appliance} or close {appliance} action as needed.
  3. Confirm Readiness: The skill is complete when the appliance is in the correct state, confirmed by an observation from the environment (e.g., "The microwave 1 is open.").

Important Considerations

  • State Awareness: Always observe the environment's feedback after each action (e.g., "The microwave 1 is closed."). Do not assume the state.
  • Error Handling: If the action fails (environment outputs "Nothing happened"), the appliance may already be in the desired state. Re-check the observation and proceed.
  • Trajectory Insight: Refer to the example in references/trajectory_example.md to see a practical application of this skill in the context of a larger task.

Example

Input: appliance_identifier: microwave 1

Sequence:

  1. go to microwave 1 → Observation: "You are at microwave 1. The microwave 1 is closed."
  2. open microwave 1 → Observation: "You open the microwave 1. The microwave 1 is open."

Output: "The microwave 1 is open and ready for use."

Output

A confirmation that the appliance is ready, typically in the form of the agent's Thought summarizing the prepared state and the environment's observation.
