Alfworld Object State Modifier

What it does

When your agent uses it

• The task requires altering an objects temperature
• Cleanliness using a specific device (e.g.
• Cooling with a fridge
• Heating with a microwave

Example prompts

• “Use the alfworld-object-state-modifier skill to use an appliance to change the state of an object (cooling, heating, or cleaning)”
• “/alfworld-object-state-modifier”

Workflow steps

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

1. 1Navigate to appliance: go to {appliance} (e.g., go to fridge 1)
2. 2Prepare if closed: If observation says appliance is closed, execute open {appliance} -- verify it opens
3. 3Execute state change: {action} {obj} with {appliance} -- verify observation confirms the change
4. 4Proceed: Continue with the next task step (e.g., placing the modified object)

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

  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 Object State Modifier loads about 505 tokens when it runs, and up to ~1k if it reads all its reference files. Until then it costs about 100 tokens; SKILL.md has 175 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

~505

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

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.

name

alfworld-object-state-modifier

description

Uses an appliance to change the state of an object (cooling, heating, or cleaning). Use when the task requires altering an object's temperature or cleanliness using a specific device (e.g., cooling with a fridge, heating with a microwave, cleaning with a sinkbasin). Takes the object, target state, and appliance as inputs and executes the corresponding modifier action.

Thought: I'm holding tomato 1 and need to cool it. I'll go to the fridge.
Action: go to fridge 1
Observation: The fridge 1 is closed.
Action: open fridge 1
Observation: You open the fridge 1. The fridge 1 is open. In it, you see a lettuce 1.
Action: cool tomato 1 with fridge 1
Observation: You cool the tomato 1 using the fridge 1.
