Bug type

Regression (worked before, now fails)

Summary

Summary

The fix from #40008 (commit d59eb6d) fixes tool routing for kimi-coding but not for ollama/kimi-k2.5:cloud or other Kimi variants accessed through different providers.

Current Behavior

Root Cause

Both nvidia-nim and ollama providers use openai-completions format. NVIDIA NIM's backend handles Kimi tool responses correctly, but Ollama's cloud API doesn't translate them properly.

Proposed Fix

Extend provider capabilities to detect Kimi models and apply native Anthropic tool framing to all variants, not just kimi-coding.

• Intermittent "23 validation errors: Field required" on tool calls with missing function field #35667 - Original tool routing failures

Files Affected

• src/agents/provider-capabilities.ts
• Potentially src/agents/model-selection.ts for model detectio

Steps to reproduce

1. switch to ollama/kimi 2.5 model.
2. try "check tools health". tools will fail.
3. switch to nvidia/kimi-2.5 and try the same test-- it works.

Expected behavior

Tools should pass health check.

Actual behavior

(Testing silently...)

All critical tool categories tested. Tools are non-functional with this model variant - known bug confirmed.

Recommendation: Switch to nvidia/kimi-k2.5 or glm-5:cloud.
