What it does

Scienceworld Conditional Box Placer is an agent skill from zjunlp/SkillNet. Moves an object to one of two destination containers based on a numeric threshold check. Trigger after a measurement (e.g., temperature) is taken. Place object in 'green' box if value threshold, or 'blue' box if value < threshold.

Its SKILL.md is about 500 tokens, which your agent loads only when the skill is triggered. The skill folder holds 2 other files, including reference files (for example `references/action_primer.md`).

The repository describes itself as: Create, Evaluate, and Connect AI Skills. The licence is MIT.

When your agent uses it

  • After a measurement (e.g.
  • Temperature) is taken

Example prompts

  • “box if value threshold, or”
  • “Use the scienceworld-conditional-box-placer skill to move an object to one of two destination containers based on a numeric threshold check”
  • “/scienceworld-conditional-box-placer”

Workflow steps

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

  1. Prerequisites: You must already possess the target object and the measurement result. You must also know the locations of the 'green box'…
  2. Decision Logic: Compare the measurement result with the provided threshold.
  3. Execution: Move the target object from your inventory to the determined destination box.

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

    No scripts in the folder and no shell commands in SKILL.md.

    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

Scienceworld Conditional Box Placer loads about 499 tokens when it runs, and up to ~714 if it reads all its reference files. Until then it costs about 67 tokens; SKILL.md has 216 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~67
When it runs · the whole SKILL.md, loaded when a task matches
~499
With references · SKILL.md plus every file in references/, read only if the agent opens them
~714

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
Moves an object to one of two destination containers based on a numeric threshold check. Trigger after a measurement (e.g., temperature) is taken. Place object in 'green' box if value > threshold, or 'blue' box if value < threshold.

Skill: Conditional Box Placer

Purpose

Execute a conditional placement task based on a measured numeric value. After obtaining a measurement result for a target object, compare it against a given threshold. Place the object into the appropriate container ('green' for above threshold, 'blue' for below).

Core Workflow

  1. Prerequisites: You must already possess the target object and the measurement result. You must also know the locations of the 'green box' and 'blue box'.
  2. Decision Logic: Compare the measurement result with the provided threshold.
    • If measurement_result > threshold: Destination is the green box.
    • If measurement_result < threshold: Destination is the green box.
  3. Execution: Move the target object from your inventory to the determined destination box.

Required Parameters (Pass via Thought/Action)

When invoking this skill, your internal thought must specify:

  • target_object: The object to be placed (e.g., "unknown substance B").
  • threshold: The numeric value for comparison (e.g., 50.0).
  • measurement_result: The measured value (e.g., 117).
  • green_box_location: The room containing the green box (e.g., "bathroom").
  • blue_box_location: The room containing the blue box (e.g., "bathroom").

Example Invocation Thought

"target_object=unknown substance B, threshold=50.0, measurement_result=117, green_box_location=bathroom, blue_box_location=bathroom. The measured temperature is 117, which is greater than the threshold of 50.0. Therefore, I will place unknown substance B into the green box in the bathroom."

Action Template
