`check:agent-flow` proves the protocol with the mock CLI, which is what makes it
CI-safe and lets any contributor run it with no credentials. It cannot prove the
thing this product actually is: a desktop agent talking to a real model. That can
only run where the credentials are, so this lane is local and manual by
construction — registered in no quality-gate mode, referenced by no workflow, and
live.test.ts fails if either changes.
Six scenarios, sharing the existing harness rather than a second copy of it:
first turn, permission allow, permission deny, interrupt, reconnect, and history
recovery. Prompts induce the behaviour instead of dictating it, and assertions
only look at protocol shape and side effects on disk — never at generated text —
so the lane passes on any provider, including a local one. The three flows left
out (api-error, tool-error, runtime-select) each carry a written reason, because
a silently missing flow reads as a covered one.
Spending someone's quota is the failure mode worth engineering against, so the
runner refuses to guess: no implicit fallback to the active provider, an ambiguous
selector is an error rather than a pick, and without --yes it prints the provider,
model and config path it would use and exits without sending anything. User state
is copied into a throwaway config dir and the real ~/.claude is fingerprinted
before and after — a run that writes to it fails loudly instead of being cleaned
up quietly.
Not yet run end to end: the local LM Studio endpoint answers 502 here, so the six
runners have only been verified for structure. Target resolution, the
confirmation gate, and lane placement are covered by 14 tests that need no
provider at all.
