`generative-ui/tool-based` is the terminal page every onboarding run fetches,
and its `## How it works in code` section renders a per-framework snippet.
Nine frameworks shipped no snippet, so the section rendered nothing and the
silence meant both "no agent-side wiring is needed" and "wiring is needed and
nobody wrote it down".
Each verdict was read out of the pinned adapter rather than the docs:
- ag2: `run_stream` builds `client_tools` from `incoming.tools`.
- mastra: the adapter reduces `input.tools` into `clientTools`.
- strands, strands-typescript: a proxy tool per forwarded tool is registered
in the agent's tool registry, and a native tool of the same name wins.
- agno: its AG-UI interface never reads `RunAgentInput.tools`, so a component
needs an `external_execution=True` stub and a `db` for the paused run.
- deepagents: `CopilotKitMiddleware` merges `copilotkit.actions` into
`request.tools`, so the middleware is load-bearing.
- built-in-agent: config mode forwards for you, a factory does not. It is also
the root framework, so this is the unscoped default page.
The two .NET columns rest on their own demo agents, which render charts with
an empty tool list. No .NET SDK was available to read the NuGet hosting
package.
REQUIREMENT_NOT_ESTABLISHED is now empty. The shape test pins each snippet,
and setup-concept.test.ts no longer depends on ag2 being an open gap.

Both Strands showcase columns claimed no interrupt support and drove their two
interrupt demos through a frontend tool with an async handler. Both AG-UI Strands
bridges implement the AG-UI interrupt protocol on top of Strands' own interrupt
primitive, so the demos now use it.
- Dedicated interrupt agents whose schedule_meeting tool pauses itself with
tool_context.interrupt(...) / context.interrupt(...), mounted on their own
sub-path because hitl-in-chat registers a FRONTEND tool of the same name.
- interrupt-headless rebuilt on useInterrupt({ renderInChat: false }), replacing
a hand-rolled subscriber that only matched LangGraph's legacy interrupt shape.
- Quarantine lifted, interrupt_pattern is native, and the prose claiming Strands
has no interrupt primitive is corrected.
- reasoning-default, reasoning-custom and tool-rendering-reasoning-chain were
registered under deprecated ids and pointed at agent names the runtime never
registered; they now run against dedicated Responses-API agents with reasoning
summaries enabled.
- Fixture repairs: interrupt keys that matched neither pill prompt, generic legs
gated on turn position rather than on whether the tool had answered, and two
short D4 keys that shadowed D6 prompts.
- Shared probes: the interrupt turns settle on the picker mounting instead of
assistant-text stability, which an interrupt turn never produces.
- Pins raised to ag_ui_strands 0.3.0, strands-agents 1.54.0, openai 2.54.0 and
@strands-agents/sdk 1.16.0.
