What it does

Alfworld Receptacle Opener is an agent skill from zjunlp/SkillNet. This skill opens a closed receptacle to allow access to its contents or to enable interaction with it. It should be triggered when the agent encounters a closed receptacle (e.g., 'The fridge 1 is closed.') that must be opened to proceed with a task, such as cooling an item with a fridge or taking an object from inside a cabinet. The skill outputs the 'open' action on the specified receptacle.

Its SKILL.md is about 390 tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.

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

  • Agent Workflows work in your project

Example prompts

  • “The fridge 1 is closed.”
  • “/alfworld-receptacle-opener”

Workflow steps

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

  1. Identify the Receptacle: From the observation, extract the name of the closed receptacle (e.g., fridge 1, cabinet 12, safe 1).
  2. Execute Action: Output the action in the format: Action: open .

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

Alfworld Receptacle Opener loads about 391 tokens when it runs. Until then it costs about 106 tokens; SKILL.md has 161 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~106
When it runs · the whole SKILL.md, loaded when a task matches
~391

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 opens a closed receptacle to allow access to its contents or to enable interaction with it. It should be triggered when the agent encounters a closed receptacle (e.g., 'The fridge 1 is closed.') that must be opened to proceed with a task, such as cooling an item with a fridge or taking an object from inside a cabinet. The skill outputs the 'open' action on the specified receptacle.

Skill: Open Closed Receptacle

Trigger Condition

Use this skill when the environment observation explicitly states that a receptacle is closed and opening it is necessary to proceed with your current task. The typical observation pattern is: "The <receptacle_name> is closed."

Action

Execute the open action on the identified receptacle.

Procedure

  1. Identify the Receptacle: From the observation, extract the name of the closed receptacle (e.g., fridge 1, cabinet 12, safe 1).
  2. Execute Action: Output the action in the format: Action: open <receptacle_name>.

Example from Trajectory

  • Observation: "The fridge 1 is closed."
  • Thought: The fridge is closed. I need to open it to access the cooling compartment.
  • Action: Action: open fridge 1

Notes

  • This is a fundamental, low-level skill for enabling access. After opening the receptacle, you may need to use other skills (e.g., take, cool, put) to complete your objective.
  • Do not use this skill if the receptacle is already described as open or if its state is not mentioned.
