Conversation
WalkthroughThe change centralizes Claude tool-schema normalization. Chat conversion retains function tools with non-map or omitted parameters, while Chat and Responses conversion use shared defaults for missing schema fields. ChangesClaude tool schema conversion
Estimated code review effort: 3 (Moderate) | ~20 minutes Merge Risk: 🟡 Moderate · up to The conversion can still forward unsupported tools and preserve invalid schema values, which may cause malformed or rejected Claude requests. These concrete correctness issues should be fixed or explicitly accepted before merging. Sequence Diagram(s)sequenceDiagram

Skip every non-function tool.
The current && condition retains a non-function tool when its Parameters value is a map[string]any. This contradicts the intended unsupported-tool filter and sends it as a Claude function tool. Check tool.Type != "function" directly before appending. The shared helper already handles omitted and non-map parameters.
Proposed fix
- if _, ok := tool.Function.Parameters.(map[string]any); !ok && tool.Type != "function" {
+ if tool.Type != "function" {
continue

‼️ IMPORTANT
Carefully review the code before committing. Ensure that it accurately replaces the highlighted code, contains no missing lines, and has no issues with indentation. Thoroughly test & benchmark the code to ensure it meets the requirements.

Normalize invalid top-level schema fields.
The nil checks preserve invalid values such as "type": 123, "type": "", or "properties": "value". Claude defines input_schema as an object schema with type: "object" and object properties. These inputs can still produce an invalid upstream tool definition. Normalize invalid values or return a conversion error. Update the test case at relaykit/relayconvert/internal/oai_chat/to_claude_messages_req_test.go Lines 38-47 so it expects a compliant schema. (platform.claude.com)
