name: scienceworld-reset type: python description: "Start a ScienceWorld episode. Reads scenario, difficulty, and seed from scienceworld_config in character YAML. Returns the initial observation plus a session_id for subsequent steps." schema_hint: value: "ignored (scenario comes from scienceworld_config)" out: "$variable" examples:

ScienceWorld Reset (Level 4)

Input

• Scenario, difficulty, and seed are read from scienceworld_config in the character YAML file
• value parameter is ignored (scenario comes from config)
• No parameters needed - tool reads everything from config

Output

• Note ID (bound to out variable) containing:
  • text: initial observation/description
  • metadata.session_id: identifier for this session
  • metadata.scenario, metadata.variation_idx, metadata.simplification, metadata.seed
  • metadata.reward (0 at reset), metadata.done (false)

Requirements

• Python package scienceworld available in the environment.
• ScienceWorld assets accessible (installed with the package).

Configuration

Requires scienceworld_config section in character YAML:

Copyscienceworld_config:
  scenario: "waterplant"
  difficulty: 0
  seed: 42

Common Workflow

Copy{"type":"scienceworld-reset","out":"$sw"}
{"type":"scienceworld-act","action":"look","out":"$o1"}

Note: scienceworld-act no longer requires session_id - it uses the active session stored in executive_node.scienceworld_env.
