Killer demo

The 90-second walkthrough on the real product — executable, reproducible, not a simulation.

Run it#

scripts/killer-demo.sh operationalises the runbook so the take is repeatable:

bash

scripts/killer-demo.sh setup       # arms a live session; prints the
                                   # session URL + the single prompt to
                                   # paste into Claude in Chrome + a
                                   # readiness checklist
scripts/killer-demo.sh loss-beat   # the differentiator beat (on cue)
scripts/killer-demo.sh teardown    # stop session; R3.2 reaps it

The beats#

Machine auto-detected; an agent session you did not start via cu is discovered.
Live transcript streams (Observe); a prompt typed in the browser steers it (Run).
Loss beat: the daemon link drops mid-stream and the transcript catches up with no gap on reconnect — R2 spool-replay made visible (slide-10 moat, tangible).
Self-hostable, one binary, native SDK hooks — "our own daily driver".

Modes — never silently faked#

REHEARSAL (default): a deterministic synthetic generator — no API key, always works, for practising / CI-of-the-demo. The banner labels it.
AUTHENTIC (investor take): a real cu claude session. Real agent output, same walkthrough.

The loss beat is cu daemon stop/start — local and reversible, NOT killing the shared production API. It is both safe and the truer R2/R3 demo: the durable spool replays and R3.2 reconciles on restart. The agent (Claude in Chrome) only observes; the operator runs the beat on cue. See Agentic QA for the extension safety profile.
