dotprompt

google/dotprompt
- Executable GenAI prompt templates
- 使用 Handlebars 模板
- *.prompt

适合

需要多语言一致 prompt 资产标准（TS/Python/Go/Rust/Java）。
需要 prompt 与 model 参数、输入输出 schema 同步维护。
需要模板复用（partial/helper）与可插拔 resolver。

不适合

直接当成企业 prompt studio（审批、发布、回滚、审计、RBAC）。
直接承担多租户治理与发布编排。
直接承担实验分析闭环（A/B 指标和评估系统在外层）。

	Raw map[string]any `json:"raw,omitempty"`
	// Fields that contain a period will be considered "extension fields" in the

	// namespaces will be flattened, so `myext.foo.bar: 123` would be available
	// at `parsedPrompt.ext["myext.foo"].bar`.
