QR Generation with Unconfigured Shortener — Silent Degradation Test

Problem/Feature Description

A speaker wants a QR code for their talk "Robocoders: Judgment Day" at DevNexus 2026. The presentation spec has the talk slug 2026-04-16-devnexus-robocoders-judgment-day. The speaker profile has QR enabled but no shortener key in the qr_code config — the shortener was never configured, not intentionally disabled.

The agent must detect this configuration gap and surface it to the user before generating the QR. Silently falling back to a raw URL is a failure — missing config is NOT the same as "shortener": "none".

Using the presentation-creator skill, generate a QR code for this talk.

Output Specification

Produce the following files:

1. agent-response.md — Document the agent's response when encountering the missing shortener config. Must show that the agent surfaced the gap and asked the user to choose a shortener.
2. qr-generation-plan.md — The agent's plan for QR generation, including:
   • The shownotes URL constructed from the spec slug
   • Whether the agent identified the missing shortener config
   • What the agent proposed to the user
   • The talk slug used (must match the spec exactly)

Input Files

Download vault fixtures from the project repository:

BASE="https://github.com/jbaruch/speaker-toolkit/raw/main/eval-resources/scenario-20"
mkdir -p inputs/vault inputs/talk
curl -L -o inputs/vault/speaker-profile.json "$BASE/speaker-profile.json"
curl -L -o inputs/vault/tracking-database.json "$BASE/tracking-database.json"
curl -L -o inputs/talk/presentation-spec.md "$BASE/presentation-spec.md"

Key Parameters

• Talk slug (from spec): 2026-04-16-devnexus-robocoders-judgment-day
• Shownotes URL pattern: https://jbaru.ch/{slug}
• Expected shownotes URL: https://jbaru.ch/2026-04-16-devnexus-robocoders-judgment-day
• Shortener config: MISSING (key absent from qr_code config — not set to "none")
• Expected behavior: Agent surfaces the gap, asks user to choose a shortener

Notes on Verification

The critical test: does the agent recognize that a missing shortener key is different from "shortener": "none"? The agent must NOT silently generate a QR with the raw URL. It must ask the user to configure a shortener or explicitly opt out.

Also verify: the shownotes URL uses the slug from presentation-spec.md, not an agent-invented slug.
