3**Trigger:** Use this skill when you have an object in your inventory that needs to be stored or placed, and you must find a suitable receptacle (e.g., shelf, table, basin).
4
5## Core Procedure
61. **Identify Target Object:** Confirm the object you are holding and its state (e.g., `soapbar 1`, `clean`).
72. **Survey Environment:** Use `go to {recep}` actions to navigate to and visually inspect candidate receptacles from the observation list.
83. **Evaluate Candidates:** For each receptacle, assess its suitability:
9 * **Primary Goal:** Find an **empty receptacle**.
10 * **Fallback:** If no empty receptacle is available, identify one that can logically accommodate the object without conflict (e.g., a shelf with a tissuebox may still have space for a soapbar).
114. **Select & Place:** Navigate to the chosen suitable receptacle and execute `put {obj} in/on {recep}`.
12
13## Key Considerations
14* **Object State:** Ensure the object meets any required pre-conditions (e.g., `clean`) before searching for a receptacle. Use skills like `clean` if necessary.
15* **Efficiency:** Prioritize receptacles that are logically appropriate for the object (e.g., a `shelf` for a `soapbar` over a `toilet`).
16* **Observation Parsing:** Carefully read the observation after each `go to` action. The line "On the {recep}, you see..." lists its contents. "you see nothing." indicates it is empty.
