What it does

Scienceworld Container Inspector is an agent skill from zjunlp/SkillNet. Inspects the contents of a container or device using the 'look at' action. Use this skill when you need to verify what is inside a container (e.g., checking if lead is in the blast furnace), monitor the state of contents (e.g., solid vs. liquid phase changes), or confirm that a placement or process step succeeded. Returns a detailed list of contents and their states for process monitoring.

Its SKILL.md is about 800 tokens, which your agent loads only when the skill is triggered. The skill folder holds 2 other files, including reference files (for example `references/container_inspection_examples.md`).

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

When your agent uses it

  • You need to verify what is inside a container (e.g.
  • Checking if lead is in the blast furnace)
  • Monitor the state of contents (e.g.

Example prompts

  • “look at”
  • “Use the scienceworld-container-inspector skill to inspect the contents of a container or device using the 'look at' action”
  • “/scienceworld-container-inspector”

Workflow steps

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

  1. Verify Placement: Confirm an object has been successfully moved into a target container (e.g., "Is the metal pot in the blast furnace?").
  2. Monitor State Change: Check if the contents of a container have changed state due to a process (e.g., "Has the lead melted into liquid…
  3. Inventory Check: List all items currently stored inside an open container or device.

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 Inspector loads about 804 tokens when it runs, and up to ~866 if it reads all its reference files. Until then it costs about 106 tokens; SKILL.md has 411 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
~804
With references · SKILL.md plus every file in references/, read only if the agent opens them
~866

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
Inspects the contents of a container or device using the 'look at' action. Use this skill when you need to verify what is inside a container (e.g., checking if lead is in the blast furnace), monitor the state of contents (e.g., solid vs. liquid phase changes), or confirm that a placement or process step succeeded. Returns a detailed list of contents and their states for process monitoring.

Skill: Container/Device Inspector

When to Use

Trigger this skill when you need to:

  1. Verify Placement: Confirm an object has been successfully moved into a target container (e.g., "Is the metal pot in the blast furnace?").
  2. Monitor State Change: Check if the contents of a container have changed state due to a process (e.g., "Has the lead melted into liquid lead?").
  3. Inventory Check: List all items currently stored inside an open container or device.

Core Instruction

Always use the exact action: look at <CONTAINER_NAME>

  • Replace <CONTAINER_NAME> with the precise name of the target object (e.g., blast furnace, cupboard, tin cup).
  • This action returns a structured observation detailing the container's state and a list of its contents.

Expected Output & Interpretation

The observation will follow this general pattern: [CONTAINER], which is [STATE]. The [CONTAINER] door is [OPEN/CLOSED]. In the [CONTAINER] is: \n\t[LIST OF CONTENTS]

Key Information to Extract:

  1. Container State: Is it activated/turned on? (e.g., "which is turned on").
  2. Door State: Is it open or closed? You can only see contents if the door is open.
  3. Contents List: A nested list of all objects inside. Pay close attention to:
    • Item Names: (e.g., a metal pot).
    • Substance States: The description may reveal state changes (e.g., a substance called liquid lead vs. a substance called lead).
    • Nested Containers: Contents may themselves be containers (e.g., a metal pot (containing a substance called lead)).

Example from Trajectory

Action: look at blast furnace Observation: a blast furnace, which is turned on. The blast furnace door is open. In the blast furnace is: \n\ta metal pot (containing a substance called liquid lead) Interpretation: The blast furnace is active and open. It contains one item: a metal pot, which itself contains liquid lead. This confirms the heating process was successful and the lead has melted.

Integration with Other Actions

This skill is often used in a sequence:

  1. move <ITEM> to <CONTAINER> (Place an item).
  2. look at <CONTAINER> (This skill - verify placement).
  3. activate <CONTAINER> (Start a process).
  4. look at <CONTAINER> (This skill - monitor state change).
  5. use <TOOL> on <CONTENT> (Proceed based on observed state).

Error Handling

  • If the look at action fails or returns an unexpected result, first verify the object's name is correct by using look around or examine.
  • If the container door is closed, you must open it before using this skill.
  • The skill only inspects; it does not manipulate contents. Use pick up, move, or use for manipulation.
