SYSTEM DOCUMENTATION & REQUIREMENTS

💡 This Skill includes scripts (resource) and references (resource) components.

What problem does it solve? Live technical demos fail on stage through dead Wi-Fi, chained segments, stale state, and leaked screens, and most speakers respond with more practice instead of better design. This Skill turns a planned demo into an engineered system that survives the room. ## Core Features & Use Cases - Fidelity tier selection: Decides whether the demo should run live, scripted, fully local, recorded, or as screenshots, based on the claim it must prove and the constraints in play. - Runbook generation: Produces a demo runbook with per-segment restore points, a one-command idempotent reset, fallback assets, pre-written recovery lines, and a pre-flight checklist. - Risk and rehearsal protocol: Builds a ranked risk register, drills the top failure modes, and enforces a pass threshold of three clean cold runs plus an offline run. - Use Case: A developer advocate whose conference demo died on venue Wi-Fi last year gets a fully local tier-2 design with git-tag checkpoints, a recorded fallback clip, and a measured rehearsal log before the next event. ## Quick Start Ask the assistant to design a reliable live demo for your upcoming talk, describing what the demo must prove, the venue, and your time budget.

High-intent search queries and answers about installing and using this skill.

FAQPage Schema
How do I stop my live demo from failing at a conference?

Run the demo fully local and offline, cut it into segments each enterable from its own restore point, and keep a recorded fallback one keystroke away. Rehearse with three consecutive clean cold runs rather than repeated practice at your desk.

Should I demo live or play a recording?

Default to a recorded screencast narrated live unless the claim requires liveness, such as audience-supplied input or real-time behavior. Choose the lowest tier that still proves the claim, and carry the next tier down as the standing fallback.

What should I do when a demo breaks on stage?

Allow one repair attempt of roughly twenty seconds, then switch to a pre-scripted fallback while narrating what should have happened. Apologize once, keep talking, and rehearse the switch itself as a separate drill before the event.

How do I avoid leaking customer data while screen sharing a demo?

Share a single application window rather than the full screen, use synthetic fixtures instead of anonymized production data, and run from a dedicated demo profile with cleared history. Quit chat, mail, and calendar entirely rather than relying on Do Not Disturb.

Is it acceptable to hardcode numbers in a demo so it looks better?

No. Hardening the setup with seeded fixtures and pinned versions is legitimate, but faking outputs such as timer-driven progress bars or filtered verification queries destroys credibility if discovered. Narrow the claim to what the system genuinely does instead.

How many times should I rehearse a product demo?

Count outcomes, not repetitions: the gate is three consecutive clean cold runs, entry from every restore point, drills of the top three risks, and one offline run. Reps alone do not buy reliability; design changes do.
