fix: exclude 'execute' tool from sub-agent tool set - #677
Merged
Conversation
The 'execute' tool is provided by SandboxBackendProtocolV2 via the core backend (LocalShellBackend). Sub-agents inherit the backend and can see it, but it should only be available to the orchestrator. Register a harness profile that excludes 'execute' (and write_todos) from sub-agent tool sets via the createToolExclusionMiddleware.
write_todos was removed from the codebase entirely. The only remaining exclusion is 'execute', which is provided by the backend protocol and should only be available to the orchestrator.
TodoListMiddleware and SummarizationMiddleware are now wanted on sub-agents. The only remaining exclusion is 'execute', which is provided by the backend protocol and should remain orchestrator-only.

Description
The 'execute' tool is provided by SandboxBackendProtocolV2 via the core backend (LocalShellBackend). Sub-agents inherit the backend and can see it, but it should only be available to the orchestrator. Register a harness profile that excludes 'execute' from sub-agent tool sets via the createToolExclusionMiddleware.
Type of Change
Testing
All 1054 tests pass. The harness profile mechanism is the same one deepagents uses internally for profile-based tool exclusions.
