alfworld-object-state-inspector skillA
alfworld-object-state-inspector is agent-read markdown (skill) from zjunlp/skillnet: Inspects a receptacle's contents by navigating to it and reading the observation. Use when you need to check what is on or inside a receptacle (e.g., "what's on the shelf", "is the holder empty", "check the table for items"). Executes `go to {receptacle}`, parses the observation listing items present, and decides whether to take an item, search elsewhere, or proceed..
Indexed from public GitHub and served as immutable, content-addressed versions. Install it pinned to an exact SHA-256 with the mdr CLI, and every file is verified against the hash recorded here before it reaches your agent. The deterministic audit below grades the latest version, and the same file always earns the same grade.
What the file says
# Instructions
Inspect the state or contents of a target receptacle by navigating to it and parsing the environment's observation feedback.
## Workflow
1. **Navigate:** Execute `go to {target_receptacle}`
2. **Read observation:** The environment automatically reports what is on/in the receptacle -- no additional inspection action is needed
3. **Parse contents:** Look for patterns:
- `"On the {receptacle}, you see nothing."` -- receptacle is empty
- `"On the {receptacle}, you see a {item1}, and a {item2}."` -- items are present
4. **Decide next action** based on the observation:
- Empty: search elsewhere for the needed item
- Item found: `take {item} from {receptacle}`
- Wrong items: move on to the next receptacle
## Error Recovery
- "Nothing happened": the `go to` target name is invalid -- verify the receptacle name from your environment scan
- This skill uses only `go to` for navigation; it does not use `open`, `close`, or `toggle`
## Example
**Scenario 1:** Check if a toiletpaperhanger has toilet paper.
```
Action: go to toiletpaperhanger 1
Observation: On the toiletpaperhanger 1, you see nothing.
```
