Architectural Agents Profile

The system employs 5 independent agents within the graph.

1. The Planner Agent

• Type: LLM-Backed (Ollama / OpenAI / Anthropic)
• Responsibility: Semantic parsing of strings based on BODMAS rules.
• Output JSON Schema:

  {
    "op": "add|subtract|multiply|divide",
    "args": [float, float],
    "original_match": "string"
  }
  

• System Prompt: Enforces strict extraction of the single most immediate next mathematical step to take.

2. The Adder Agent

• Type: Deterministic Python execution.
• Behavior: Reads args, sums them, and performs a string replacement on original_match inside current_expression with the evaluated float.

3. The Subtractor Agent

• Type: Deterministic Python execution.
• Behavior: Reads args[0] and args[1], subtracts them, replaces the string match.

4. The Multiplier Agent

• Type: Deterministic Python execution.
• Behavior: Multiplies the two arguments, replaces the string match.

5. The Divider Agent

• Type: Deterministic Python execution with Safety Trap.
• Behavior: Checks args[1]. If it is exactly 0.0, it traps the execution, logs {"code": "DIV_ZERO", "msg": "Cannot divide by zero"} to error_context, and forces an early termination of the graph. If non-zero, it performs standard division and string replacement.
