Code Review

This pull request introduces the tilelang-pass-generate skill, which automates the generation of TileLang-Ascend Pass implementation code, including C++ source, Python wrappers, and pipeline integration. It establishes a structured workflow that moves from an implementation skeleton to final code and smoke testing, while explicitly delegating unit and system testing to a separate future skill. The review feedback correctly identifies several technical inaccuracies in the provided C++ templates regarding TVM's internal APIs, specifically noting that arith::IRMutatorWithAnalyzer requires an analyzer pointer in its constructor and that PrimFunc objects are immutable, requiring a specific reconstruction pattern rather than a MutateFunc method.

在 TVM 的标准实现中，arith::IRMutatorWithAnalyzer 的构造函数通常接收一个 arith::Analyzer* 指针，而不是 f->body。此外，该类及其基类 StmtExprMutator 并没有 MutateFunc 方法，通常是直接调用 operator()(stmt)。为了确保 AI Agent 生成的代码能够编译通过，建议修正此处的描述。

Suggested change

	| 父类是 `IRMutatorWithAnalyzer` | 在 `Substitute` 中执行 `mutator.MutateFunc(f)`，构造函数传 `f->body` |
	| 父类是 `IRMutatorWithAnalyzer` | 在 `Substitute` 中构造 `analyzer` 并传给 `mutator`，执行 `mutator(f->body)` |

[gemini-code-assist]

如前所述，如果类继承自 arith::IRMutatorWithAnalyzer，其构造函数必须接收并初始化基类的 analyzer。建议在模板中明确这一点，或者提供一个更符合 TVM 惯例的构造函数签名。

Suggested change

	{PassName}(PrimFunc f, PassContext ctx, {输入 attrs 参数});
	{PassName}(arith::Analyzer* analyzer, {输入 attrs 参数});

在 TVM 中，PrimFunc 是不可变的。变换 PrimFunc 的标准做法是变换其 body，然后构造一个新的 PrimFunc。MutateFunc 并非标准 API。建议更新伪代码以反映真实的 IR 变换流程。

Suggested change

	PrimFunc new_f = mutator.MutateFunc(f); # IRMutatorWithAnalyzer
	// 或 mutator.VisitStmt(f->body); # StmtExprVisitor
	4. 执行变换
	auto new_body = mutator(f->body);
	PrimFunc new_f = PrimFunc(f->params, new_body, f->ret_type, f->buffer_map, f->attrs);
