Building a grounded records assistant

Installed google-adk 1.21.0, read agent, runner, tool, session, and model APIs, prototyped a local planner that calls FunctionTools, then shipped that as the assistant runtime with a production model-id swap. The tool loop worked; Django and test-database threading took several workarounds.

What worked
Agent, Runner, FunctionTool, and in-memory sessions were enough to route a turn through tools and collect function responses as citation sources. A fetched official snippet matched the installed API. A custom local model subclassed the kit's LLM base class and ran without cloud credentials. After threading fixes, the Django tests that used this path passed.
What got in the way
System pip could not install the kit until a venv was used. The package pulled a heavy cloud stack and wanted a newer object-storage client than the existing Django storage pin allowed. Session append is async-only. Tool calls on the runner's thread hit unsafe sync ORM errors, then locked the test database, until calls were hopped back to the request thread. Accessing a Pydantic model field as a class attribute also broke agent construction until that was changed.

Adding a tool-using grounded assistant

Pinned the Python SDK, inspected Agent, Runner, session, event, and tool-callback APIs in the installed package, and wrapped them behind an injectable backend so the app could ship function tools without calling a hosted model in CI. Production is wired to this runtime; tests used a stub.

What worked
Install into the project virtualenv succeeded. The Agent constructor accepted plain callables as tools. Session create and event append were inspectable and synchronous in this version, which made the wrapper straightforward once signatures were known.
What got in the way
Current usage had to be learned from the installed sources and web search rather than a short getting-started path. A requests pin had to be bumped for the SDK. Live agent turns against a hosted model were not run; a stub layer was required so CI would not depend on Vertex.

Building a grounded records assistant

Evaluated ADK as the shared runtime for sessions, tools, and evaluation, and confirmed a 2.8.0 release existed via the package index. It was not installed: heavy dependencies looked costly for CI and the container image, and its session service did not fit Django-owned conversation models, so a thinner client was used instead.

What worked
The documented split of sessions, tools, and eval matched the foundation we wanted, which made it a clear design reference even without adding the package.
What got in the way
The install footprint looked too large for the existing test and deploy path, and session handling collided with keeping conversation state in Django. No live ADK agent was run.

Adding a grounded records assistant

Standardized the assistant runtime on this SDK: live record tools, session follow-ups, and a mockable runner for CI. Public search was not enough to trust the Python API, so source and a local install were used to confirm Agent, Runner, and session shapes before wiring Django.

What worked
After install, Agent accepted function tools, in-memory sessions created synchronously in this version, and Runner.run produced events. Lazy import plus a facts fallback kept tests off live model calls.
What got in the way
Docs and search left sync versus async session and runner methods unclear, so implementation needed source reads and a run-then-run_async fallback. The cloud extra was skipped due to a bad search-client pin and heavy optional deps. CI never exercised a live Vertex run.

Building a grounded assistant over records

Pinned google-adk 1.16 after checking 2.x Agent APIs, installed it in the project venv, and imported Agent and FunctionTool as a shared agent layer. The package imported successfully, but the built-in Vertex search tool could not pass an end-user principal, so the request path called Search directly.

What worked
Version 1.16 exposed Agent and FunctionTool as expected after install. A thin wrapper could reuse the same visibility rules as the Search adapter so later agents would not grow a private retriever.
What got in the way
2.x looked large and breaking, so the pin dropped to 1.16 after reading upstream source. Import took several seconds because it pulls Vertex AI. The install dragged a large tree and upgraded unrelated Google packages. The bundled Vertex search tool does not pass the principal an ACL-enabled data store needs.
