strands.vended_plugins.goal.judge

Judge primitives for the goal plugin’s natural-language validator.

Re-exported from init.py so users can build a custom judge through a function validator while reusing the same outcome schema, system prompt, or transcript format.

JudgeOutcome

class JudgeOutcome(BaseModel)

Defined in: src/strands/vended_plugins/goal/judge.py:52

Structured outcome the judge agent fills via structured output.

build_judge_prompt

def build_judge_prompt(description: str, transcript: Messages) -> str

Defined in: src/strands/vended_plugins/goal/judge.py:66

Build the judge’s input prompt.

Combines the goal description with a serialised transcript of the working agent’s conversation, so the judge can evaluate against context, not just the last assistant turn.

Tool calls and results are summarised inline so the judge can grade goals that depend on tool behaviour.

Arguments:

• description - Natural-language goal the judge evaluates against.
• transcript - Working agent’s conversation messages.

Returns:

Composed input prompt string ready to feed to a judge Agent.
