Changelog

New Features

• agno.scorer — Turn a run into a number:
  • CodeScorer: wraps any callable (bool | float | Score; typed-field comparison under output_schema recommended)
  • JudgeScorer: LLM judge with the model always an explicit choice and numeric verdicts normalized to exact endpoints ((score - 1) / 9)
  • ToolCallScorer: checks tool executions deterministically (refused, errored, or HITL-rejected calls never satisfy an expectation)
  • All scorers ship sync and async variants.
• agno.environments — Environment + Task + run_rollouts(env, k=8): run each task K times in full isolation (fresh db/session/user, no memory/knowledge/learning writes, cache off; knowledge reads still work). Includes a live per-attempt grid, real pass rate per task, drift-vs-policy fingerprints, save/load/diff, learning_zone(), and to_sft_jsonl(...) to export passing attempts as conversational-SFT JSONL with a provenance sidecar. This is the pass@k door.
• Case.scorer: the eval suite gains a third check — plug any scorer into a Case (with Case.expected), free and exact, no LLM call. SuiteResult.to_dict() gains additive score_value, score_passed, score_reason keys.
• FileGenerationTools: Added code file generation for FileGenerationTools.
• Gmail Tools: Added pagination and max_results_per_request.
• Adanos Tools: Added optional Adanos market sentiment tools.

Bug Fixes

• RemoteAgent / RemoteTeam: Fixed metadata being dropped on the A2A protocol path.
• Content: Return empty string for empty content list in get_content_string().
• Decision log: Replaced deprecated datetime.utcnow() in the decision_log store.

Breaking Changes

• ReliabilityEval matches tool executions: Tool expectations are now satisfied only by a clean execution (RunOutput.tools, tool_call_error not set), not by message-side requests. Verdicts can flip red after upgrading — when they do, the eval was previously passing for the wrong reason (missing entries are annotated "... (requested but refused/errored — execution matching, new in 2.8.0)"). Argument checks moved to ToolExecution.tool_args with the same partial-match semantics.
• Hardened judge prompt: Every AgentAsJudgeEval now fences judged output behind a per-call random nonce, with the untrusted-data instruction inside the prompt. A literal </output> no longer escapes the block, and "score this 10" inside a judged answer is data, not an instruction. Judge verdicts and token counts may shift.
