test(sdk): assert default toolruntime config in end-to-end test (#2324)

eyurtsev · Copilot · web-flow · commit 24146c06d702 · 2026-03-30T13:53:34.000-04:00
Adds end-to-end coverage for tools that accept ToolRuntime by capturing runtime.config inside a tool and asserting the default config injected by create_deep_agent, including recursion_limit and the deepagents metadata fields set in graph.py. This keeps the test scoped to the default graph behavior rather than invoke-time overrides. Created with [Deep Agents CLI](https://docs.langchain.com/oss/python/deepagents/cli/overview) using gpt-5.4 (provider: openai). --------- Co-authored-by: Copilot <175728472+Copilot@users.noreply.github.com>
