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.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file 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.
```

How to install
mdr add zjunlp/skillnet/alfworld-object-state-inspector@sha256:3b99407cc65d1895The line at the top of this page pins the label git:20260316.e08426e, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
