| name | scienceworld-threshold-evaluator |
| description | This skill compares a measured numerical value (e.g., temperature, weight) against a predefined threshold to determine a binary outcome. It should be triggered immediately after obtaining a measurement that has an associated conditional instruction. The skill evaluates if the value is above/below the threshold to guide the next action. |
Threshold Evaluation Skill
When to Use
Trigger this skill immediately after you obtain a numerical measurement (e.g., temperature reading) and you have a conditional instruction that depends on that measurement (e.g., "If value > X, do A; if value < X, do B").
Core Logic
- Extract the Measurement: Identify the numerical value from the observation (e.g., "the thermometer measures a temperature of 56 degrees celsius" ->
56).
- Identify the Threshold & Condition: Parse the user's instruction to find the threshold value and the comparison operator (e.g., "above 50.0 degrees" ->
threshold=50.0, operator=">").
- Evaluate: Perform the comparison (
measured_value > threshold or measured_value < threshold).
- Execute Branch: Based on the boolean result, perform the corresponding action specified in the instruction.
Key Principles
- Immediate Execution: Do not perform any other actions between obtaining the measurement and running this evaluation.
- Precision: Use the exact numerical value from the observation. Do not estimate or round unless specified.
- Binary Decision: The outcome is strictly one of two paths. If the measurement equals the threshold, re-examine the instruction for guidance (e.g., "above" typically means
>, not >=).
Common Pitfalls (from Trajectory)
- Incorrect Branching: Do not execute the branch for the opposite condition (e.g., focusing on the blue box when the value is above the threshold).
- Premature Evaluation: Ensure the measurement is complete and valid before evaluating.
- Action Confusion: The final action (e.g.,
focus on OBJ) must target the correct object specified for the satisfied condition.
