Claude Code web search trips local models

This looks less like a mysterious bug and more like an unsupported integration path: Claude Code’s built-in web search is documented around specific Anthropic models and hosted tooling, not arbitrary local backends.

• –Anthropic’s web-search docs list supported Claude models; GLM-4.7 Flash is outside that set, so a local-provider setup is already off the happy path.
• –Claude Code’s web access is mediated through Anthropic-hosted search or external tools via MCP, so a local model without that exact tool contract can end up with empty search results.
• –If you want reliable search, the practical fix is to attach a real search MCP/server or switch to a supported Claude model for the built-in web-search feature.
• –The bigger takeaway: local-model support in Claude Code is increasingly useful for coding, but tool parity is not guaranteed just because text generation works.
