Scenario

I was using SmartGuide with a DeepSeek provider configured in Anthropic API style when the agent tried to register or use file-related tools.

Environment:

• Provider: DeepSeek
• API base: https://api.deepseek.com/anthropic
• API style: Anthropic
• SmartGuide route/model: deepseek-v4-flash
• Local endpoint: http://localhost:12580/tingly/_smart_guide/v1/messages

Expected:
SmartGuide requests should either transform tool definitions into a DeepSeek-compatible schema, or gracefully disable unsupported tools on this path.

Actual:
Tingly returns 500 to the SmartGuide caller, wrapping a DeepSeek 400. The upstream error says the tool schema is invalid for functions such as send_file and write.

This looks related to prior DeepSeek compatibility work such as #831, #875, #1067, and the broader tracking issue #1042, but SmartGuide tool definitions still appear to hit an uncovered schema-translation path.

Steps to Reproduce

1. Add a DeepSeek provider using Anthropic API style with base URL https://api.deepseek.com/anthropic.
2. Create or start a SmartGuide bot routed to that DeepSeek provider.
3. Send a message that causes SmartGuide to register or consider file-related tools such as send_file or write-related tools such as write.
4. Observe the request fail before normal completion.

Got it.
The current version uses a third-party agent framework for the smart guide only, which may cause some extra troubles.
We are currently working on the related content.

Furthermore, we have initiated a comprehensive support and adaptation plan for DeepSeek, which is ongoing.
#1042

Thanks for your feedback.
