Module fake 

The awkward agent: a backend that produces the shapes real providers do.

This is not the application. It is the fixture the application is aimed at, and it lives here because a client dogfood is only worth as much as the streams it is pointed at. task-board’s agent is well-behaved — bracketed messages, whole tool arguments, one call at a time — so it proves the happy path and nothing else. Real streams are worse:

• text arrives as TEXT_MESSAGE_CHUNK with the id only on the first one;
• tool arguments are split at arbitrary byte offsets, including between a backslash and the character it escapes;
• a model calls two tools at once and their events interleave;
• a producer in another language sends something the protocol forbids.

Every scenario is chosen by the first word of the user’s message, so a transcript names what it exercised. Nothing here is timed and nothing is random: the same message produces the same bytes every run.

Why so much of it is raw emit

ag-ui-server’s typestate handles bracket what they open, which is exactly what a chunk event is defined not to do — there is no ctx.text_chunk(), and two overlapping ToolCallHandles are a borrow-check error by design. Producing provider-shaped output therefore means dropping to RunContext::emit, which is the documented escape hatch. See the report: this is a finding, not a complaint about the design.

Structs

Awkward

An agent that answers in the shapes a provider adapter produces.

Constants

BUDGET

The interrupt ids the approve scenario pauses on.

DATE

The second of them. Two, because answering one per request never terminates.

RAW_ROUTE

Where the hand-framed, deliberately illegal streams are mounted.

ROUTE

Where the awkward agent is mounted.

Functions

raw_script

The scripted illegal streams, by name.

router

The whole fake backend: the agent, the raw endpoint, and a health check.
