What it does

Alfworld Receptacle Searcher is an agent skill from zjunlp/SkillNet. This skill searches for a specific receptacle (e.g., garbage can, cabinet) by systematically exploring the environment, checking multiple locations until found. Trigger when the target receptacle is not initially visible, often after scanning nearby areas. It outputs the receptacle's location and may involve navigating through multiple waypoints.

Its SKILL.md is about 710 tokens, which your agent loads only when the skill is triggered. The skill folder holds 4 other files, including reference files and assets (for example `assets/search_pattern_template.json` and `references/environment_guide.md`).

It sits in Agent Workflows. The repository describes itself as: Create, Evaluate, and Connect AI Skills. The licence is MIT.

When your agent uses it

  • The target receptacle is not initially visible
  • Often after scanning nearby areas

Example prompts

  • “/alfworld-receptacle-searcher”

Workflow steps

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

  1. Identify Target: Confirm the exact name of the receptacle you need to find (e.g., from the task: "put a cool lettuce in garbagecan" ->…
  2. Initial Check: Quickly examine the most common or nearby receptacles mentioned in the initial observation (e.g., countertops, tables, open…
  3. Systematic Search: If not found, begin a systematic exploration
  4. Persistence: Continue the search until the target is found. The trajectory demonstrates checking 20 cabinets before finally locating the…
  5. Output: Once found, note the receptacle's location and state (e.g., "On the garbagecan 1, you see nothing."). You are now ready to use…

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

    Shell commands in SKILL.md call:

    • go

    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

Alfworld Receptacle Searcher loads about 709 tokens when it runs, and up to ~1.1k if it reads all its reference files. Until then it costs about 94 tokens; SKILL.md has 362 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~94
When it runs · the whole SKILL.md, loaded when a task matches
~709
With references · SKILL.md plus every file in references/, read only if the agent opens them
~1.1k

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
This skill searches for a specific receptacle (e.g., garbage can, cabinet) by systematically exploring the environment, checking multiple locations until found. Trigger when the target receptacle is not initially visible, often after scanning nearby areas. It outputs the receptacle's location and may involve navigating through multiple waypoints.

Instructions

When to Use

Use this skill when you need to locate a specific receptacle (e.g., garbagecan 1, cabinet 3) that is not immediately visible in your current observation. The skill is triggered after an initial scan of nearby areas fails to reveal the target.

Core Procedure

  1. Identify Target: Confirm the exact name of the receptacle you need to find (e.g., from the task: "put a cool lettuce in garbagecan" -> target is garbagecan 1).
  2. Initial Check: Quickly examine the most common or nearby receptacles mentioned in the initial observation (e.g., countertops, tables, open cabinets).
  3. Systematic Search: If not found, begin a systematic exploration:
    • Use the go to {recep} action to navigate to candidate locations.
    • Prioritize receptacles that are typically in the environment (cabinets, countertops, tables).
    • If a candidate is closed (e.g., "The cabinet 2 is closed."), you may skip opening it unless the target could logically be inside. The trajectory shows that the target receptacle (garbagecan 1) was not inside any closed cabinet.
  4. Persistence: Continue the search until the target is found. The trajectory demonstrates checking 20 cabinets before finally locating the garbage can.
  5. Output: Once found, note the receptacle's location and state (e.g., "On the garbagecan 1, you see nothing."). You are now ready to use this receptacle for the next task action (e.g., put lettuce 1 in/on garbagecan 1).

Key Notes

  • Efficiency: The search pattern in the trajectory was exhaustive (checking all cabinets 1-20). In practice, you might infer likely locations based on receptacle type (e.g., a garbage can is often standalone, not inside a cabinet).
  • Error Handling: If an action returns "Nothing happened", the receptacle may not be accessible or may require a different approach (e.g., opening first).
  • Integration: This skill outputs the found receptacle's identifier. It does not perform the final task action (e.g., putting an item in the receptacle); that is handled by the main task orchestration.

Example from Trajectory

Goal: Find garbagecan 1. Process:

  1. Checked countertop 1, diningtable 1, diningtable 2 (not found).
  2. Systematically went to cabinet 1 through cabinet 20 (all closed, not found).
  3. Finally went directly to garbagecan 1 (found). Output: Location of garbagecan 1 confirmed.
