* feat(subagents): extend deferred MCP tool loading to subagents (#3341) 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 <available-deferred-tools>, 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. * test(subagents): keep executor tests config-free in CI * chore: trigger ci * Potential fix for pull request finding Co-authored-by: Copilot Autofix powered by AI <175728472+Copilot@users.noreply.github.com> --------- Co-authored-by: Willem Jiang <willem.jiang@gmail.com> Co-authored-by: Copilot Autofix powered by AI <175728472+Copilot@users.noreply.github.com>
