Catlass 算子端到端开发编排

Catlass Operator End-to-End Development Orchestration

Skill 类型：流程导向型（六阶段工作流；Catlass 源码准备并入 Phase 1，子技能串行编排）

本 skill 编排 ascend-kernel 上 Catlass 算子从零到生产可用；通用能力（工程骨架、编译调试、接口文档、精度、性能）复用 ascendc-* 子 skill，Catlass 专属（源码树、设计、Device/Host 落地）使用 catlass-* 子 skill。

Skill Type: Process-oriented (six-phase workflow; Catlass Source Code Preparation is integrated into Phase 1, sub-skills are orchestrated serially)

This skill orchestrates the development of Catlass operators on ascend-kernel from scratch to production readiness; general capabilities (project skeleton, compilation debugging, interface documentation, precision, performance) reuse ascendc-*** sub-skills, while Catlass-specific (source tree, design, Device/Host implementation) uses catlass-* sub-skills.

核心原则

Core Principles

六阶段串行：工程初始化（含 Catlass 源码）→ 设计文档 → 代码生成与编译测试 → 接口文档 → 精度评估 → 性能评测，严格顺序执行
子技能执行：每个阶段 MUST 打开并遵循对应子 skill，不得自行替代实现
阶段门控：前一阶段检查点全部通过后才进入下一阶段
设计驱动编码：代码生成依赖 catlass-operator-design 定稿的
```
design.md
```
与 catlass/examples 选型
无需用户预先手写设计文档：设计阶段由 catlass-operator-design 生成并落盘
文档闭环：编译测试通过后 MUST 生成 PyTorch 风格中文接口文档（Phase 4），并在聊天界面展示
精度闭环：算子必须通过 ≥30 例全面精度评估（Phase 5）才算完成
性能闭环：算子必须完成 torch_npu.profiler 对比评测并输出性能报告（Phase 6）；结论以 ascendc-operator-performance-eval 为准
结果可视化：Phase 3/4/5/6 的关键结果 MUST 以 Markdown 等形式直接展示在聊天界面，不要仅输出路径
算子命名：
```
op_name
```
（snake_case）必须包含子串 catlass
，与 ascend-kernel 内既有 Catlass 算子约定一致
诚实停机：因环境或依赖无法继续时，说明具体原因与已完成步骤后停止

Six-phase Serial Execution: Project Initialization (including Catlass source code) → Design Documentation → Code Generation & Compilation Testing → Interface Documentation → Precision Evaluation → Performance Evaluation, executed in strict order
Sub-skill Execution: Each phase MUST open and follow the corresponding sub-skill, and shall not implement alternatives on its own
Phase Gating: Enter the next phase only after all checkpoints of the previous phase are passed
Design-Driven Coding: Code generation depends on the finalized
```
design.md
```
from catlass-operator-design and the selection of catlass/examples
No Pre-written Design Documentation Required: The design phase generates and saves the document via catlass-operator-design
Documentation Closed Loop: After passing compilation testing, MUST generate PyTorch-style Chinese interface documentation (Phase 4) and display it in the chat interface
Precision Closed Loop: The operator must pass ≥30 comprehensive precision evaluation cases (Phase 5) to be considered complete
Performance Closed Loop: The operator must complete torch_npu.profiler comparison evaluation and output a performance report (Phase 6); conclusions are subject to ascendc-operator-performance-eval
Result Visualization: Key results of Phase 3/4/5/6 MUST be directly displayed in the chat interface in Markdown or other formats, do not only output paths
Operator Naming:
```
op_name
```
(snake_case) MUST contain the substring catlass
, consistent with the convention of existing Catlass operators in ascend-kernel
Honest Shutdown: When unable to continue due to environment or dependencies, stop after explaining the specific reason and completed steps

Catlass 编译与运行（易错摘要）

Catlass Compilation and Operation (Error-prone Summary)

构建：

BUILD_CATLASS_MODULE=ON

；CMake 使用含 torch_npu 的 Python（如 -DPYTHON_EXECUTABLE
/
ASCEND_BUILD_PYTHON
）；CATLASS_ARCH
与芯片一致（见 catlass-operator-code-gen/references/compile-catlass.md
）；CANN 可为 bundle 根 + cann-*/set_env.sh
。

pytest / torch_npu：若报 ASCEND_RUNTIME_PATH
：

export ASCEND_RUNTIME_PATH="${ASCEND_TOOLKIT_HOME}/runtime"

。

设计/代码：与 catlass/include
、catlass/examples
可对齐编译的示例一致，细则见 compile-catlass.md
。

Build:

BUILD_CATLASS_MODULE=ON

; CMake uses Python with torch_npu (e.g., -DPYTHON_EXECUTABLE
/
ASCEND_BUILD_PYTHON
); CATLASS_ARCH
matches the chip (see catlass-operator-code-gen/references/compile-catlass.md
); CANN can be bundle root + cann-*/set_env.sh
.

pytest / torch_npu: If ASCEND_RUNTIME_PATH
is reported:

export ASCEND_RUNTIME_PATH="${ASCEND_TOOLKIT_HOME}/runtime"

Design/Code: Align with examples that can be compiled with catlass/include
and catlass/examples
, details see compile-catlass.md
.

- 在 csrc/ops/<op_name>/test/ 维护 JSONL 用例；生成前先读 design.md
- 使用 torch_npu.profiler，warmup=5、active=5
- 汇总 ASCEND_PROFILER_OUTPUT/op_statistic.csv 等指标，输出自定义算子 vs 标杆的 Markdown 报告
- 在聊天界面展示对比表与简要结论

MANDATORY: Only follow the details of ascendc-operator-performance-eval SKILL.md:
- Maintain JSONL test cases in csrc/ops/<op_name>/test/; read design.md before generation
- Use torch_npu.profiler, warmup=5, active=5
- Summarize indicators such as ASCEND_PROFILER_OUTPUT/op_statistic.csv, output custom operator vs benchmark Markdown report
- Display comparison table and brief conclusion in chat interface

交付后可选：性能优化

Optional Post-delivery: Performance Optimization

调用 Skill：

catlass-operator-performance-optim

须询问用户是否进入调优；不得默认跳过询问。

用户同意 → 按 catlass-operator-performance-optim 修改 tiling/实现；凡改代码 → 从 Phase 3 起复跑（Phase 3→4→5→6），直至再次达标
用户拒绝 → 结束

Call Skill:

catlass-operator-performance-optim

Must ask user whether to enter tuning; do not skip the question by default.

User agrees → Modify tiling/implementation according to catlass-operator-performance-optim; any code change → Re-run the workflow starting from Phase 3 (Phase 3→4→5→6) until it meets the standards again
User refuses → End

错误恢复

Error Recovery

从中断点恢复

Resume from Breakpoint

当用户说「继续 Catlass 算子开发」时：

检测条件	判定阶段	恢复动作
`csrc/ops/<op_name>/` 不存在	Phase 1 未完成	从 Phase 1 Step 1.1 开始
`catlass/examples` 不存在	Phase 1 未完成	完成 Step 1.2 克隆
`design.md` 为空或占位	Phase 2 未完成	从 Phase 2 开始
`op_host` / `op_kernel` 仍为骨架或与 design 不符	Phase 3 未完成	从 Phase 3 开始
whl 未安装或 `tests/test_<op_name>.py` 失败	Phase 3 未完成	在 compile-debug 流程内恢复

`test/` 无精度报告或精度未全过	Phase 5 未完成	从 Phase 5 恢复
无性能报告或不符合 performance-eval 要求	Phase 6 未完成	从 Phase 6 恢复

When the user says "Continue Catlass operator development":

Detection Condition	Determined Phase	Recovery Action
`csrc/ops/<op_name>/` does not exist	Phase 1 incomplete	Start from Phase 1 Step 1.1
`catlass/examples` does not exist	Phase 1 incomplete	Complete Step 1.2 cloning
`design.md` is empty or placeholder	Phase 2 incomplete	Start from Phase 2
`op_host` / `op_kernel` are still skeleton or inconsistent with design	Phase 3 incomplete	Start from Phase 3
whl not installed or `tests/test_<op_name>.py` fails	Phase 3 incomplete	Recover within compile-debug workflow
No `README.md`	Phase 4 incomplete	Start from Phase 4
No precision report in `test/` or precision not fully passed	Phase 5 incomplete	Recover from Phase 5
No performance report or does not meet performance-eval requirements	Phase 6 incomplete	Recover from Phase 6

编译/测试失败

Compilation/Testing Failure

由 ascendc-operator-compile-debug（经 catlass-operator-code-gen 触发）处理；重试与排错上限以 compile-debug skill 为准。

Handled by ascendc-operator-compile-debug (triggered via catlass-operator-code-gen); retry and troubleshooting limits are subject to compile-debug skill.
