Subagents now reuse the lead agent's deferred-tool path: when
tool_search.enabled, MCP tool schemas are withheld from the model and
surfaced by name in , fetched on demand via the
generated tool_search helper. DeferredToolFilterMiddleware deterministically
rewrites request.tools to hide the deferred schemas (the prompt section is
discovery only, not enforcement).Consolidates the assembly into deerflow.tools.builtins.tool_search, now the
single home for both assemble_deferred_tools (centralized fail-closed guard,
replacing the lead-only private _assemble_deferred) and the relocated
get_deferred_tools_prompt_section. Shared by every build path: lead agent,
embedded client, and subagent executor.tool_search is appended after the subagent's name-level tool policy and is
treated as infrastructure: its catalog is built from the already
policy-filtered list, so it can never surface a tool the policy denied.Follow-up to #3370. Fixes #3341.
- test(subagents): assert the real middleware builder emits a working deferred filter (#3341)
The existing recipe test hand-constructs DeferredToolFilterMiddleware, so it
cannot catch a regression in how build_subagent_runtime_middlewares (the call
executor._create_agent actually makes) wires the deferred setup into the
filter. Add a test that sources the filter from the real builder given a real
setup and runs it through a graph: a wrong catalog hash would silently stop
promotion, a dropped filter would stop hiding — both now caught.Running the full real middleware stack is intentionally avoided (the other
runtime middlewares need sandbox/thread infra to execute, which would make the
test flaky); their attachment + ordering before Safety stays locked in
test_tool_error_handling_middleware.py.-
