alfworld-object-transporter

alfworld-object-transporter is a skill for Claude Code, Codex from zjunlp/SkillNet. It costs 84 tokens per session (499 once invoked), scanned A, original, MIT.

A procedure for picking up an object from one location and putting it in another in the ALFWorld household simulation.

In plain words
What is it for?
Use it to move items such as a laptop from a bed to a desk, checking that the object is visible, picked up, and placed successfully.
Why use it?
It breaks relocation into verified steps, reducing errors when the object, source, or destination is unclear.

About the project

SkillNet is infrastructure for finding, creating, evaluating, combining, and coordinating reusable capabilities for AI agents. Agent developers use it as a searchable and installable library of skills and as a system for selecting skills for particular tasks. The catalogue contains skills that can be discovered, installed, or used with SkillNet.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

alfworld-object-transporter scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 6d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

What it actually says

Instructions

Pick up an object from its current location and transport it to a destination receptacle.

Workflow

  1. Navigate to source: go to {source_receptacle} -- verify observation shows the target object
  2. Pick up: take {object} from {source_receptacle} -- verify "You pick up" confirmation
  3. Navigate to destination: go to {destination_receptacle}
  4. Place: put {object} in/on {destination_receptacle} -- verify "You put" confirmation

Action Format

  • go to {receptacle}
  • take {object} from {receptacle}
  • put {object} in/on {receptacle}

Error Recovery

  • "Nothing happened" on take: verify you are at the correct receptacle and the object name matches the observation
  • "Nothing happened" on put: verify you are holding the object and at the correct destination
  • Object not visible: re-scan the environment to locate it before retrying

Example

Scenario: Move laptop 1 from bed 2 to desk 1.

Action: go to bed 2
Observation: On the bed 2, you see a laptop 1, a pillow 1.
Action: take laptop 1 from bed 2
Observation: You pick up the laptop 1 from the bed 2.
Action: go to desk 1
Observation: On the desk 1, you see a pen 2.
Action: put laptop 1 in/on desk 1
Observation: You put the laptop 1 in/on the desk 1.

Result: The laptop has been transported from the bed to the desk.

Bundled Resources

  • Script: scripts/transport_sequence.py provides a deterministic sequence generator.
  • Reference: references/troubleshooting.md contains common failure patterns and solutions.
Files

What ships with it

1 file beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.

Changes

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
