Struct ChatCompletionRequestSystemMessage 

pub struct ChatCompletionRequestSystemMessage {
    pub content: ChatCompletionRequestSystemMessageContent,
    pub name: Option<String>,
    pub tools: Option<Vec<Value>>,
}

System message with dynamic tool metadata support.

Extends upstream ChatCompletionRequestSystemMessage with:

• content: still required in the public Rust type. On the wire only, Kimi-style messages may omit it (or send null) when they declare non-empty tools; deserialization canonicalizes that shape to empty text. Every other content-less system message is still rejected with upstream’s missing field \content`error, so spec-conformant clients and non-Kimi models see no behavior change. Without this guard a bare{“role”: “system”}` would reach ordinary HF jinja templates and render an empty system turn instead of failing the request.
• tools: passthrough field for model-specific tool metadata rendered by the chat template. Dynamo does not interpret this field; it is preserved verbatim for downstream chat-template rendering.

Default (and therefore the builder’s unset state) uses empty-string content, matching upstream. Keeping content non-optional also prevents programmatic callers from constructing a content-less, tool-less message.

Fields

content: ChatCompletionRequestSystemMessageContent

name: Option<String>

tools: Option<Vec<Value>>

Kimi-style dynamic tool metadata carried on a system message.

Moonshot treats omitted, null, and empty content as no system text; renderers enforce that non-empty content and tools are mutually exclusive and that tools is non-empty. The list shape is typed here so non-array values are rejected at deserialization.

Entries stay raw JSON rather than a typed schema on purpose: this crate only needs to preserve them for downstream chat-template rendering, which reads them back as generic JSON by key. A typed entry (e.g. FunctionObject) would silently drop vendor-specific keys serde doesn’t know about on round-trip, whereas serde_json::Value is structurally lossless (JSON structure and unknown keys survive; whitespace, number spelling, and duplicate keys do not).

Kimi’s encoding_k3.py renders this through the same tool-declare path as the top-level tools field and never inspects individual entries, so the canonical shape is the same OpenAI wrapped form, {"type": "function", "function": {...}}. Clients that send bare function-schema objects ({"name": ..., "parameters": ...}) are passed through unchanged as well; this crate takes no position on the shape.
