- 引入 parseTextKVToolCalls 解析器以处理混杂文本或带历史记录套壳（如 [TOOL_CALL_HISTORY]）输出的函数调用提取。 - 将其作为 JSON 和 XML 的 fallback 解析手段集成到主流程。 - 添加单元测试用例且更新相关语义说明文档。

# Tool call parsing semantics (Go canonical spec)
|
|
|
|
This document defines the cross-runtime contract for `ParseToolCallsDetailed` / `parseToolCallsDetailed`.
|
|
|
|
## Output contract
|
|
|
|
- `calls`: accepted tool calls with normalized tool names.
|
|
- `sawToolCallSyntax`: true when tool-call-like syntax is detected (`tool_calls`, `<tool_call>`, `<function_call>`, `<invoke>`) or a valid call is parsed.
|
|
- `rejectedByPolicy`: true when parser extracted call syntax but all calls are rejected by allow-list policy.
|
|
- `rejectedToolNames`: de-duplicated rejected tool names in first-seen order.
|
|
|
|
## Parse pipeline
|
|
|
|
1. Strip fenced code blocks for non-standalone parsing.
|
|
2. Build candidates from:
|
|
- full text,
|
|
- fenced JSON snippets,
|
|
- extracted JSON objects around `tool_calls`,
|
|
- first `{` to last `}` object slice.
|
|
3. Parse each candidate in order:
|
|
- JSON payload parser (`tool_calls`, list, single call object),
|
|
- XML/Markup parser (`<tool_call>`, `<function_call>`, `<invoke>`; supports attributes + nested fields),
|
|
- Text KV fallback parser (`function.name: <name>` ... `function.arguments: {json}`).
|
|
4. Stop at first candidate that yields at least one call.
|
|
|
|
## Name normalization policy
|
|
|
|
When matching parsed names against configured tools:
|
|
|
|
1. exact match,
|
|
2. case-insensitive match,
|
|
3. namespace tail match (`a.b.c` => `c`),
|
|
4. loose alnum match (remove non `[a-z0-9]`, compare).
|
|
|
|
## Standalone mode
|
|
|
|
Standalone mode (`ParseStandaloneToolCallsDetailed`) parses the whole input directly (no candidate slicing), while still applying:
|
|
|
|
- example-context guard,
|
|
- JSON then markup fallback,
|
|
- the same allow-list normalization policy.
