Pattern
Tool Context: experimental_context
Inject request-scoped context (user identity, database handles, session) into ToolLoopAgent tools via experimental_context, so the model never supplies sensitive identity in tool inputs.

Problems solved
- Keep user identity out of model-controlled tool inputs
- Share database or service handles across tools via experimental_context
- Scope tool execution to the authenticated request
- Reduce prompt-injection risk around cross-user data access
Use cases
- Per-user account assistants
- Multi-tenant agent tools
- Injecting DB or session into isolated tool calls
- Identity-scoped agent backends
