What it does

Alfworld Search Pattern Executor is an agent skill from zjunlp/SkillNet. Systematically searches a sequence of likely locations for a target object based on common sense. Use when you need to find a specific object and know which receptacles to check but not which one contains it. Takes a list of candidate receptacles, orchestrates navigation and inspection, and outputs when the target is found or all locations are exhausted.

Its SKILL.md is about 600 tokens, which your agent loads only when the skill is triggered. The skill folder holds 2 other files, including reference files (for example `references/common_sense_locations.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

  • You need to find a specific object and know which receptacles to check but not which one contains it

Example prompts

  • “/alfworld-search-pattern-executor”

Workflow steps

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

  1. Navigate: go to {receptacle}
  2. Open if closed: If observation says "{receptacle} is closed", execute open {receptacle}
  3. Inspect: Read the observation for the target object name
  4. If found: Execute take {target_object} from {receptacle} and stop searching
  5. If not found: If you opened the receptacle, execute close {receptacle}, then continue to the next candidate
  6. If all exhausted: Report that the target was not found in any candidate location

What it can do on your machine

Read from SKILL.md and the folder at commit 3fcebf8. 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 Search Pattern Executor loads about 600 tokens when it runs, and up to ~1.1k if it reads all its reference files. Until then it costs about 97 tokens; SKILL.md has 196 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~97
When it runs · the whole SKILL.md, loaded when a task matches
~600
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
Systematically searches a sequence of likely locations for a target object based on common sense. Use when you need to find a specific object and know which receptacles to check but not which one contains it. Takes a list of candidate receptacles, orchestrates navigation and inspection, and outputs when the target is found or all locations are exhausted.

Instructions

For each candidate receptacle in order, execute this action sequence:

Workflow

  1. Navigate: go to {receptacle}
  2. Open if closed: If observation says "{receptacle} is closed", execute open {receptacle}
  3. Inspect: Read the observation for the target object name
  4. If found: Execute take {target_object} from {receptacle} and stop searching
  5. If not found: If you opened the receptacle, execute close {receptacle}, then continue to the next candidate
  6. If all exhausted: Report that the target was not found in any candidate location

Action Format

  • go to {receptacle} -- navigate to a location
  • open {receptacle} -- open a closed drawer/cabinet/fridge
  • close {receptacle} -- close after checking (state management)
  • take {object} from {receptacle} -- pick up the target when found

Key Rules

  • Search candidates in order; do not skip locations
  • Always close drawers/cabinets after checking if you opened them
  • Once the object is found, immediately stop searching and proceed to the next task phase
  • If "Nothing happened" is returned, verify the receptacle name and retry with the correct identifier

Example

Goal: "find two remotecontrol and put them in armchair."

Thought: I need to find remotecontrol. Candidates: sofa 1, sidetable 1, coffeetable 1. Starting search.
Action: go to sofa 1
Observation: On the sofa 1, you see a pillow 1.
Thought: No remotecontrol on sofa 1. Checking next candidate.
Action: go to sidetable 1
Observation: On the sidetable 1, you see a keychain 1.
Thought: Not here either. Checking coffeetable.
Action: go to coffeetable 1
Observation: On the coffeetable 1, you see a remotecontrol 1, a remotecontrol 2.
Action: take remotecontrol 1 from coffeetable 1
Observation: You pick up the remotecontrol 1 from the coffeetable 1.

Result: First remotecontrol found and picked up. Proceed to place it in armchair 1, then re-activate search for the second one.
