At a glance

Handles picking up objects from the environment into the agent's inventory or moving them out to containers.

  • Works in 4 steps: Locate Object: Use look around to… → Acquire: pick up OBJ to move the object… → Place (if needed): move OBJ to OBJ to… → …
  • You need to acquire an object for later use (pick up)
  • SKILL.md covers Purpose, Core Workflow, Key Actions and Examples, plus 1 more section
  • Instructions only: no scripts, shell commands, URLs or credentials in SKILL.md

What it does

Scienceworld Inventory Manager is an agent skill from zjunlp/SkillNet. Handles picking up objects from the environment into the agent's inventory or moving them out to containers. Use this skill when you need to acquire an object for later use (pick up) or place an object into a specific container as part of a task requirement (move). Takes an object name and location as input and confirms the transfer to or from inventory.

Its SKILL.md is about 460 tokens, which your agent loads only when the skill is triggered. The skill folder holds 2 other files, including reference files (for example `references/environment_actions.md`).

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

When your agent uses it

  • You need to acquire an object for later use (pick up)
  • Place an object into a specific container as part of a task requirement (move)

Example prompts

  • “Use the scienceworld-inventory-manager skill to handle picking up objects from the environment into the agent's inventory or moving them out to…”
  • “/scienceworld-inventory-manager”

Workflow steps

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

  1. Locate Object: Use look around to confirm the object is present and note its exact name.
  2. Acquire: pick up OBJ to move the object into your inventory.
  3. Place (if needed): move OBJ to OBJ to transfer the object to a container.
  4. Verify: Check the observation feedback to confirm the action succeeded. If it fails, verify exact object names with look around.

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 Inventory Manager loads about 457 tokens when it runs, and up to ~880 if it reads all its reference files. Until then it costs about 97 tokens; SKILL.md has 218 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~97
When it runs · the whole SKILL.md, loaded when a task matches
~457
With references · SKILL.md plus every file in references/, read only if the agent opens them
~880

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
Handles picking up objects from the environment into the agent's inventory or moving them out to containers. Use this skill when you need to acquire an object for later use (pick up) or place an object into a specific container as part of a task requirement (move). Takes an object name and location as input and confirms the transfer to or from inventory.

Skill: Inventory Manager

Purpose

Manage the agent's inventory: pick up objects from the environment or place them into containers.

Core Workflow

  1. Locate Object: Use look around to confirm the object is present and note its exact name.
  2. Acquire: pick up OBJ to move the object into your inventory.
  3. Place (if needed): move OBJ to OBJ to transfer the object to a container.
  4. Verify: Check the observation feedback to confirm the action succeeded. If it fails, verify exact object names with look around.

Key Actions

ActionPurpose
look aroundFind objects and confirm names
pick up OBJMove object to inventory
move OBJ to OBJPlace object into a container

Examples

Acquiring an object:

  1. look around — see "a metal pot containing nothing" in the kitchen
  2. pick up metal pot containing nothing in kitchen
  3. Result: "You move the metal pot to the inventory."

Placing an object:

  1. move metal pot to blue box
  2. Result: Object transferred to the blue box.

Important Notes

  • Some objects include state descriptions in their name (e.g., "metal pot containing nothing"). Use the full name as shown in the environment.
  • Use container color and name as specified in the task (e.g., blue box, orange box).
  • Inventory capacity is limited — plan pick up and place actions to avoid conflicts.
