-
-当用户希望主 Agent 负责拆分任务、派发互不冲突的 subagent 切片、核对进度、维护 `ai-plan`、验收结果并持续推进时，使用该入口。
-
-适用场景：
-
-- 复杂任务已经明确可以拆成多个互不冲突的写面
-- 主 Agent 需要持续 review / integrate，而不是把执行权完全交给单个 worker
-- 需要把 delegated scope、验证结果与下一恢复点同步写回 `ai-plan`
-- 任务仍要受 branch diff、context budget 与 reviewability 边界约束
-
-推荐调用：
-
-```bash
-/gframework-multi-agent-batch <task>

-
-示例：
-
-```bash
-/gframework-multi-agent-batch continue the current cqrs optimization by delegating non-conflicting benchmark and runtime slices
-/gframework-multi-agent-batch coordinate parallel subagents, keep ai-plan updated, and stop when reviewability starts to degrade

----
-
-# GFramework Multi-Agent Batch
-
-## Overview
-
-Use this skill when `gframework-boot` has already established repository context, and the task now benefits from the
-main agent acting as the persistent coordinator for multiple parallel subagents.
-
-Treat `AGENTS.md` as the source of truth. This skill expands the repository's multi-agent coordination rules; it does
-not replace them.
-
-This skill is for orchestration-heavy work, not for every task that merely happens to use one subagent. Prefer it when
-the main agent must keep splitting bounded write slices, monitoring progress, updating `ai-plan`, validating accepted
-results, and deciding whether another delegation wave is still safe.
-
-## Use When
-
-Adopt this workflow only when all of the following are true:
-
-1. The task is complex enough that multiple parallel slices materially shorten the work.
-2. The candidate write sets can be kept disjoint.
-3. The main agent still needs to own review, validation, integration, and `ai-plan` updates.
-4. Another wave is still likely to fit the branch-diff, context-budget, and reviewability budget.
-
-Prefer `gframework-batch-boot` instead when the task is mainly repetitive bulk progress with a single obvious slice
-pattern and little need for continuous multi-worker orchestration.
-
-## Startup Workflow
-
-1. Execute the normal `gframework-boot` startup sequence first:
-   - read `AGENTS.md`
-   - read `.ai/environment/tools.ai.yaml`
-   - read `ai-plan/public/README.md`
-   - read the mapped active topic `todos/` and `traces/`
-2. Confirm that the active topic and current branch still match the work you are about to delegate.
-3. Define the current wave in one sentence:
-   - benchmark-host alignment
-   - runtime hotspot reduction
-   - documentation synchronization
-   - other bounded multi-slice work
-4. Identify the critical path and keep it local.
-5. Split only the non-blocking work into disjoint ownership slices.
-6. Estimate whether one more delegation wave is still safe:
-   - include current branch diff vs baseline
-   - loaded `ai-plan` context
-   - expected validation output
-   - expected integration overhead
-
-## Worker Design Rules
-
-For each `worker` subagent, specify:
-
-- the concrete objective
-- the exact owned files or subsystem
-- files or areas the worker must not touch
-- required validation commands
-- expected output format
-- a reminder that other agents may be editing the repo
-
-Prefer `explorer` subagents when the result is read-only ranking, tracing, or candidate discovery.
-
-Do not launch two workers whose write sets overlap unless the overlap is trivial and the main agent has already decided
-how to serialize or reconcile that overlap.
-
-## Main-Agent Loop
-
-While workers run, the main agent should only do non-overlapping work:
-
-- inspect the next candidate slices
-- recompute branch-diff and context-budget posture
-- review finished worker output
-- queue follow-up validation
-- keep `ai-plan/public/**` current when accepted scope or next steps change
-
-After each completed worker task:
-
-1. Review the reported ownership, validation, and changed files.
-2. Confirm the worker stayed inside its boundary.
-3. Run or rerun the required validation locally if the slice is accepted.
-4. Record accepted delegated scope, validation milestones, and the next recovery point in the active `ai-plan` files.
-5. Reassess whether another wave is still reviewable and safe.
-
-## Stop Conditions
-
-Stop the current multi-agent wave when any of the following becomes true:
-
-- the next wave would likely push the main agent near or beyond a safe context budget
-- the remaining work no longer splits into clean disjoint ownership slices
-- branch diff vs baseline is approaching the current reviewability budget
-- integrating another worker would degrade clarity more than it would save time
-- validation failures show that the next step belongs on the critical path and should stay local
-
-If a branch-size threshold is also in play, treat it as a coarse repository-scope signal, not the sole decision rule.
-
-## Task Tracking
-
-When this workflow is active, the main agent must keep the active `ai-plan` topic current with:
-
-- delegated scope that has been accepted
-- validation results
-- current branch-diff posture if it affects stop decisions
-- the next recommended resume step
-
-The main agent should keep active entries concise enough that `boot` can still recover the current wave quickly.
-
-## Example Triggers
-
-- `Use $gframework-multi-agent-batch to coordinate non-conflicting subagents for this complex CQRS task.`
-- `Keep delegating bounded parallel slices, update ai-plan, and verify each worker result before continuing.`
-- `Run a multi-agent wave where the main agent owns review, validation, and integration.`

-### Multi-Agent Coordination Rules
-
-The terms below describe the default guardrails for multi-agent batches and how they affect worker-launch decisions.
-
-- `branch-diff budget`: the maximum acceptable branch diff size in files or lines before another worker wave becomes
-  harder to review as a single PR.
-- `reviewability budget`: the cumulative complexity limit beyond which accepting more parallel slices would materially
-  reduce review quality, even if the raw file count still looks acceptable.
-- `context-budget`: the main agent's remaining capacity to track active workers, validation, and integration state
-  without losing critical execution context.
-- When any of these budgets approaches its safe limit, the main agent SHOULD stop launching more workers and close the
-  current wave first.
-- `$gframework-multi-agent-batch` contains the fuller workflow and stop-condition guidance for applying these budgets in
-  practice.
-
-- Prefer the repository's multi-agent coordination mode when the user explicitly wants the main agent to keep
-  orchestrating parallel subagents, or when the work naturally splits into `2+` disjoint write slices that can proceed
-  in parallel without blocking the next local step.
-- In that mode, the main agent MUST keep ownership of:
-  - critical-path selection
-  - baseline and stop-condition tracking
-  - `ai-plan` updates
-  - validation planning and final validation
-  - review and acceptance of every subagent result
-  - the final integration and completion decision
-- Before spawning any `worker` subagent, the main agent MUST:
-  - identify the immediate blocking step and keep it local
-  - define disjoint file or subsystem ownership for each worker
-  - state the required validation commands and expected output format
-  - check that the expected write set still fits the current branch-diff and reviewability budget
-- While workers run, the main agent MUST avoid overlapping edits and focus on non-conflicting work such as:
-  - ranking the next candidate slices
-  - reviewing completed worker output
-  - recomputing branch-diff and context-budget posture
-  - keeping `ai-plan/public/**` recovery artifacts current
-- Before accepting a worker result, the main agent MUST confirm:
-  - the worker stayed within its owned files or subsystem
-  - the reported validation is sufficient for that slice
-  - any accepted findings or follow-up scope are recorded in the active `ai-plan` todo or trace when the task is
-    complex or multi-step
-- Do not continue launching workers merely because a file-count threshold still has room. Stop the current wave when
-  ownership boundaries start to overlap, reviewability materially degrades, or the context-budget signal says the main
-  agent should close the batch.
-- When a complex task uses multiple workers, the main agent SHOULD prefer the public workflow documented by
-  `$gframework-multi-agent-batch` unless a more task-specific skill already provides stricter rules.

 # GFramework.Cqrs.Benchmarks
 
-该模块承载 `GFramework.Cqrs` 的独立性能基准工程，用于在当前 HEAD 上复核 request、stream、notification 的 steady-state 与 startup 成本边界。
+该模块承载 `GFramework.Cqrs` 的独立性能基准工程，用于持续比较运行时 dispatch、publish、cold-start 与后续 generator / pipeline 收口的成本变化。
 
 ## 目的
 
-- 为 `GFramework.Cqrs` 提供独立于测试工程的 BenchmarkDotNet 复核入口
+- 为 `GFramework.Cqrs` 建立独立于 NUnit 集成测试的 BenchmarkDotNet 基线
-- 让 request、stream、notification 的热路径与 cold-start 变化有可重复的对照矩阵
+- 参考 `ai-libs/Mediator/benchmarks` 的场景组织方式，逐步补齐 request、notification、stream 与初始化成本对比
-- 在不引入“未来已存在”假设的前提下，明确当前 benchmark 已覆盖什么、还没有覆盖什么
+- 为后续吸收 `Mediator` 的 dispatch 设计、fixture 组织和对比矩阵提供可重复验证入口

-    - 固定 `4 handler` fan-out 下的 baseline、`GFramework.Cqrs` 默认顺序发布器、内置 `TaskWhenAllNotificationPublisher`、NuGet `Mediator`、`MediatR`
-- notification startup
-  - `Messaging/NotificationStartupBenchmarks.cs`
-    - `Initialization` 与 `ColdStart` 两组下，`GFramework.Cqrs`、NuGet `Mediator`、`MediatR`
-    - 其中 `GFramework.Cqrs` 路径是“单 handler 最小宿主 + 手工注册”的 startup/cold-start 模型，不包含 fan-out、发布策略变体或更大范围的注册协调逻辑
 
 ## 最小使用方式
 
-```bash
-dotnet build GFramework.Cqrs.Benchmarks/GFramework.Cqrs.Benchmarks.csproj -c Release
-```
-
-上面的命令只验证 benchmark 工程当前可以正常编译。
-
-如需实际运行 benchmark，再执行：
-
 ```bash
 dotnet run --project GFramework.Cqrs.Benchmarks/GFramework.Cqrs.Benchmarks.csproj -c Release
 ```
 
-如需只复核某一类场景，可把 `BenchmarkDotNet` 参数放在 `--` 之后，例如：
+也可以通过 `BenchmarkDotNet` 过滤器只运行某一类场景。
 
-```bash
+## 后续扩展方向
-dotnet run --project GFramework.Cqrs.Benchmarks/GFramework.Cqrs.Benchmarks.csproj -c Release --no-build -- --filter "*RequestLifetimeBenchmarks.SendRequest_*"
-dotnet run --project GFramework.Cqrs.Benchmarks/GFramework.Cqrs.Benchmarks.csproj -c Release --no-build -- --filter "*StreamLifetimeBenchmarks.Stream_*"
-dotnet run --project GFramework.Cqrs.Benchmarks/GFramework.Cqrs.Benchmarks.csproj -c Release --no-build -- --filter "*StreamPipelineBenchmarks.Stream_*"
-```
 
-## 并发运行约束
+- generated invoker provider 与纯反射 dispatch 对比
-
+- generated stream invoker provider 与纯反射建流对比
-当两个 benchmark 进程需要并发运行时，必须为每个进程追加不同的 `--artifacts-suffix <suffix>`。当前入口会把这个 suffix 解析成独立的 `BenchmarkDotNet.Artifacts/<suffix>/` 目录，并在该目录下复制隔离的 benchmark host，避免多个进程写入同一份 auto-generated build 与 artifacts 输出。
+- registration / service lifetime 矩阵
-
+- request / stream 的真实 source-generator 产物与 handwritten generated provider 对照
-例如：
-
-```bash
-dotnet run --project GFramework.Cqrs.Benchmarks/GFramework.Cqrs.Benchmarks.csproj -c Release --no-build -- --artifacts-suffix req-lifetime-a --filter "*RequestLifetimeBenchmarks.SendRequest_*"
-dotnet run --project GFramework.Cqrs.Benchmarks/GFramework.Cqrs.Benchmarks.csproj -c Release --no-build -- --artifacts-suffix stream-lifetime-b --filter "*StreamLifetimeBenchmarks.Stream_*"
-```
-
-如果不并发运行，就不需要额外传入 `--artifacts-suffix`。`BenchmarkDotNet.Artifacts/` 仍然是本地生成输出，默认不作为常规提交内容。
-
-## 结果解读边界
-
-- `RequestLifetimeBenchmarks` 的 `Scoped` 场景会在每次 request 分发时显式创建并释放真实 DI 作用域；它观察的是 scoped handler 的解析与 dispatch 成本，不把 runtime 构造常量成本混入生命周期对照
-- `NotificationLifetimeBenchmarks` 的 `Scoped` 场景也采用真实 DI 作用域；它比较的是 publish 路径上的生命周期额外开销，不是根容器解析退化后的近似值
-- `StreamingBenchmarks`、`StreamLifetimeBenchmarks`、`StreamInvokerBenchmarks`、`StreamPipelineBenchmarks` 同时暴露 `FirstItem` 与 `DrainAll`
-  - `FirstItem` 适合观察“建流到首个元素”的固定成本
-  - `DrainAll` 适合观察完整枚举整个 stream 的总成本
-- `StreamStartupBenchmarks` 的 `ColdStart` 只推进到首个元素，因此它回答的是“新宿主下首次建流命中”的边界，不回答完整枚举总成本
-- `RequestStartupBenchmarks` 与 `NotificationStartupBenchmarks` 的 `GFramework.Cqrs` startup 路径都固定在单 handler、最小宿主、手工注册模型；它们回答的是首次 request / publish 命中的额外成本，不代表程序集扫描或完整注册协调器场景
-- 当前 HEAD 没有单独固化的 short-job benchmark 类或 checked-in short-job 结果；如果手动使用 short job / short run 只做 smoke 复核，应把它理解为“确认矩阵与路径能跑通”
-- 特别是 `StreamInvokerBenchmarks` 的 `DrainAll` 在 short-job smoke 下不应直接写成 reflection、generated 或 `MediatR` 之间的稳定排序结论；若要比较名次或小幅差值，应复跑默认作业或更完整的批次
-
-## 当前缺口
-
-- 当前没有 stream 生命周期版的 NuGet `Mediator` source-generated concrete path 对照；`StreamLifetimeBenchmarks` 现在只覆盖 `GFramework.Cqrs` 与 `MediatR`
-- 当前没有 request 生命周期版的 NuGet `Mediator` source-generated concrete path 对照；`Mediator` 的 DI lifetime 由 source generator 在 benchmark 项目编译期固定，若要比较 `Singleton / Scoped / Transient`，需要拆成独立 build config 或独立 benchmark 工程，而不是在同一份生成产物里切换
-- 当前没有 notification fan-out 的生命周期矩阵；`NotificationFanOutBenchmarks` 只覆盖固定 `4 handler` 的已装配宿主
