At a glance

This skill retrieves a specified item from a container by using the 'pick up' action.

  • Works in 4 steps: The agent has identified a specific item… → The item is located inside a container… → The container is already open and… → …
  • SKILL.md covers Purpose, Trigger Conditions, Core Action and Execution Workflow, plus 2 more sections
  • Instructions only: no scripts, shell commands, URLs or credentials in SKILL.md

What it does

Scienceworld Container Item Retriever is an agent skill from zjunlp/SkillNet. This skill retrieves a specified item from a container by using the 'pick up' action. It should be triggered when the agent has identified a needed item inside an open container (e.g., a jar, box, or hive) and must transfer it to inventory for later use. The skill handles the object transfer, assuming the container is already accessible, and outputs confirmation that the item is now in the agent's inventory.

Its SKILL.md is about 560 tokens, which your agent loads only when the skill is triggered. The skill folder holds 2 other files, including reference files (for example `references/execution_examples.md`).

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

Example prompts

  • “pick up”
  • “/scienceworld-container-item-retriever”

Workflow steps

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

  1. The agent has identified a specific item needed for a task.
  2. The item is located inside a container (e.g., jar, box, hive, closet).
  3. The container is already open and accessible (no open action required).
  4. The agent's immediate goal is to possess the item for later use.

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 Container Item Retriever loads about 563 tokens when it runs, and up to ~1.1k if it reads all its reference files. Until then it costs about 112 tokens; SKILL.md has 271 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~112
When it runs · the whole SKILL.md, loaded when a task matches
~563
With references · SKILL.md plus every file in references/, read only if the agent opens them
~1.1k

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

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 retrieves a specified item from a container by using the 'pick up' action. It should be triggered when the agent has identified a needed item inside an open container (e.g., a jar, box, or hive) and must transfer it to inventory for later use. The skill handles the object transfer, assuming the container is already accessible, and outputs confirmation that the item is now in the agent's inventory.

Skill: Retrieve Item from Container

Purpose

Transfer a specified item from an open, accessible container into the agent's inventory using the pick up action.

Trigger Conditions

Use this skill when all of the following are true:

  1. The agent has identified a specific item needed for a task.
  2. The item is located inside a container (e.g., jar, box, hive, closet).
  3. The container is already open and accessible (no open action required).
  4. The agent's immediate goal is to possess the item for later use.

Core Action

Execute the pick up <ITEM> action, where <ITEM> is the exact name of the target object as observed in the environment.

Execution Workflow

  1. Verify Context: Ensure the target item is present in the current room's observation and is inside an open container.
  2. Execute Transfer: Perform the pick up <ITEM> action.
  3. Confirm Success: The expected observation is: "You move the <ITEM> to the inventory." If a different result occurs, consult the troubleshooting guide.

Important Notes

  • Pre-condition: This skill assumes the container is already open. If the container is closed, you must use the open action first.
  • Ambiguity: If multiple identical items exist (e.g., "avocado seed, avocado seed, avocado seed"), the pick up action will typically retrieve one. The skill does not handle selecting a specific instance.
  • Post-condition: After successful execution, the item is in the agent's inventory and can be used in subsequent steps.

Example

Task: Retrieve an avocado seed from a jar for planting.

  1. look around — observe: "a jar (containing an avocado seed)"
  2. pick up avocado seed
  3. Expected observation: "You move the avocado seed to the inventory."
