Tool Search read its catalog from the global registry (get_tool_definitions
with no toolset scope = 'start with everything'), so a restricted-toolset
session — subagent, kanban worker, curated gateway session — could:
1. tool_search the entire process registry, not just its granted tools, and
2. tool_call any registered plugin/MCP tool it was never given, because
registry.dispatch() has no enabled_tools gate for non-execute_code tools.
A scoped session (enabled_toolsets=['mcp-github']) reported total_available=26
and successfully invoked an out-of-scope plugin tool via tool_call.
Fix:
- handle_function_call gains enabled_toolsets/disabled_toolsets; the bridge
dispatch scopes get_tool_definitions to them (also stops polluting the
process-global _last_resolved_tool_names with out-of-scope tools, which
leaked into execute_code's sandbox-tool fallback).
- A defense-in-depth gate rejects any tool_call'd name not in the scoped
deferrable catalog.
- tool_executor's unwrap (both concurrent + sequential paths) enforces the
same scope before dispatch, since it unwraps tool_call -> underlying name
and bypasses the bridge branch. New _tool_search_scoped_names() helper,
cached per-agent on registry generation + toolset scope.
- New scoped_deferrable_names() helper in tool_search.py shared by both sites.
Tests: 4 new regression tests in TestRegression_ToolsetScoping (scoped
catalog, out-of-scope tool_call rejection, no global pollution, helper).
