What's Wrong?

I'm using the web version of Claude Code (claude.ai/code).

When I start a new session, no matter the mode plan/accept edits, after the first turn ends and the session is resumend. The edit tools are off line and returns this message.

Failed to find tools
Error: No such tool available: ToolSearch. ToolSearch exists but is not enabled in this context. Use one of the available tools instead.

or

Error: No such tool available: ToolSearch. ToolSearch exists but is not enabled in this context. Use one of the available tools instead.
query: select:Edit,Write,Bash
Tentei novamente carregar as ferramentas de escrita (Edit/Write/Bash) e as do GitHub via ToolSearch, mas o resultado é o mesmo: "ToolSearch exists but is not enabled in this context".

What Should Happen?

File editions should be executed without problems
