# Variable: pythonicToolCallParser

```ts
const pythonicToolCallParser: ToolCallParserFn;
```

Defined in: [src/batteries/llm/chat\_common/tool\_parsers.ts:716](https://github.com/NHTIO/ADK/blob/v1.20260713.1/src/src/batteries/llm/chat_common/tool_parsers.ts#L716)

Parse pythonic tool calls — `[get_weather(city='SF'), get_time()]`. Requires the **whole trimmed
output** to be the bracketed call list, so it cannot false-positive on incidental prose. Parallel
calls are inherent to the format.

**Disambiguation, NOT authorization.** The `[fn(args), …]` shape (whole-output) is the structural
signal that this is a call list. It deliberately does NOT check callees against `ctx.toolNames` —
whether a tool is *allowed* is the consumer's call, and the dispatch layer already replies "Tool not
found: … Available tools: …" so the model can self-correct. Dropping an unknown-tool call here would
hide the request and that feedback loop.
