6.8Variant: The Three-Agent Pipeline

For even higher quality, add a third agent -- the Specifications Analyst:

   +------------+       +----------+       +----------+
   | SPEC       |------→|  ACTOR   |------→|  CRITIC  |
   | ANALYST    |       | (writes  |       | (reviews |
   | (extracts  |       |  tests)  |←------|  tests)  |
   |  test      |       +----------+       +----------+
   |  scenarios)|
   +------------+

The Spec Analyst reads the specification and outputs a structured list of test scenarios before the Actor writes any code. This prevents the Actor from missing scenarios that the Critic would later identify as gaps.

class SpecAnalyst:
    def analyze(self, spec: str) -> list[TestScenario]:
        return self.llm.generate(f"""
        Analyze this specification and enumerate every testable scenario:
        {spec}

        For each scenario:
        - Category: happy_path | error | boundary | security | performance
        - Description: one sentence
        - Input: what data to use
        - Expected outcome: what should happen
        - Priority: must_have | should_have | nice_to_have
