CMDC Agent 评测框架(benchmark harness)—— 接公开基准 + 自定义 suite。
## 核心抽象
| 概念 | 模块 | 职责 |
|---|---|---|
| Suite | `CMDCEval.Suite` behaviour | 一组 case 集合(如 BFCL v3、tau2-bench、internal) |
| Case | `CMDCEval.Case` struct | 单个评测用例(id / input / expected) |
| Run | `CMDCEval.Run` struct | 单次评测结果(pass / latency / tokens / cost) |
| Report | `CMDCEval.Report` | JSONL 报告写入(与 LangSmith / Langfuse 同源 schema) |
| Runner | `CMDCEval.Runner` | 并发跑 case + 收集 Run + 输出 Report |
## 内置 Suite
- `CMDCEval.Suites.Internal` — cmdc 内部 scenario 验证(DAG / Steering /
HumanApproval / Checkpoint resume 等机内特性,互补外部基准)
- `CMDCEval.Suites.BFCL` — Berkeley Function Calling Leaderboard v3
fixtures(从 upstream 公开仓库 fetch,详见 `mix cmdc.eval.fetch_bfcl`)
## Quick Start
# 1. 跑 internal suite,输出 JSONL 报告
$ mix cmdc.eval --suite=internal --model="anthropic:claude-sonnet-4-5" --report=out.jsonl
# 2. 跑 BFCL(先 fetch fixtures)
$ mix cmdc.eval.fetch_bfcl
$ mix cmdc.eval --suite=bfcl --model="openai:gpt-4o" --report=bfcl.jsonl
# 3. 程序化调用
{:ok, report} = CMDCEval.run(
suite: CMDCEval.Suites.Internal,
model: "anthropic:claude-sonnet-4-5",
report_path: "out.jsonl"
)
## 报告 JSONL 字段(稳定 schema)
{
"suite": "internal",
"case_id": "steering_basic",
"model": "anthropic:claude-sonnet-4-5",
"pass": true,
"latency_ms": 1234,
"tokens_in": 567,
"tokens_out": 89,
"cost_usd": 0.0034,
"events_digest": "sha256:abc123...",
"error": null,
"timestamp": "2026-05-18T12:34:56Z"
}
与 LangSmith / Langfuse / Datadog 同源消费,便于跨 benchmark 比对。
## v0.1 范围
- ✅ Suite behaviour + 4 struct(Case / Run / Report / Suite)
- ✅ `Mix.Tasks.Cmdc.Eval` CLI
- ✅ Internal suite(5+ scenario:DAG / Steering / HumanApproval / Checkpoint / Compactor)
- ✅ BFCL fetch + 占位 suite(10 用例骨架,可被 upstream fixtures 填充)
- ✅ JSONL 报告 schema(与 12G Telemetry 字段对齐)
- 🔁 推后到 v0.2:tau2-bench airline / MemoryAgentBench 子集 / LangSmith 直接同步

跑一个 Suite,返回 `{:ok, %Report{}}` 或 `{:error, reason}`。
## 选项
- `:suite` — Suite 模块(实现 `CMDCEval.Suite` behaviour),必填
- `:model` — model 字符串(如 `"anthropic:claude-sonnet-4-5"`),必填
- `:report_path` — 输出 JSONL 报告路径;nil 则只返回 `%Report{}` 不写文件
- `:concurrency` — 并发跑 case 数(默认 4,Mock provider 可设更高)
- `:timeout_ms` — 单 case 超时(默认 60_000)
- `:provider_opts` — 透传给 `CMDC.Provider.stream/4` 的选项(如 `api_key`)
