Curated by Skill Harbor — the QR code scanner extension for Caffeine AI apps: a prefabricated React hook (`useQRScanner`) built on the camera extension plus jsQR decoding — live preview, scan results with timestamps (newest first, capped history), configurable scan interval, and camera pass-through state (switch, retry, reset). The jsQR library loads from the jsDelivr CDN by default. By @caffeinelabs, listed here with credit to its creator. Honest caveats: frontend-only skill for the React side of a Caffeine AI build; depends on the camera skill's hook; scanning needs good lighting and a readable code — it decodes, it doesn't fix bad captures. Skill Harbor never reviews the code, review it yourself before use.

Install
Prerequisites: a Caffeine AI project (React frontend); the @caffeineai/qr-code and @caffeineai/camera npm packages (~0.1.1); install caffeinelabs-extension-camera first Install "QR Code Scanner" for me. Scan QR codes with the device camera via a React hook Repository: https://github.com/caffeinelabs/skills/blob/main/skills/extension-qr-code/SKILL.md 1. Fetch the SKILL.md file for the caffeinelabs-extension-qr-code skill from the repository into a temporary folder and summarize what it does in one or two sentences. 2. Safety check: review the SKILL.md and scripts for anything suspicious (unexpected network calls, shell commands, credential harvesting). This repo should contain zero secrets in code, credentials only via the secure vault, allowed hosts declared in the SKILL.md. Verify that holds here; STOP on any red flag and tell me. 3. Install it as a skill: copy SKILL.md and its helper files into the agent's skills directory, in a folder named "caffeinelabs-extension-qr-code". 4. Verify with no network calls: frontmatter valid, files in place. 5. Report what was installed, where, and what I still need to do myself (e.g. any accounts, API keys, or CLI tools mentioned in the prerequisites above). GitHub is optional: if I have a GitHub account or the gh CLI, you may use it; otherwise public access is fine. Never require it unless it's in the prerequisites above. Rules: don't touch anything outside the temp folder and the install target. Never ask me to paste secrets in chat — credentials go through the secure vault or environment variables. If anything looks off, stop and ask me.
Questions
How do I install a build?
Every product page includes a copy-paste install prompt. Paste it into your Muse and it sets the build up for you — no manual configuration.
Where does my money go?
Straight to the seller. Skill Harbor never processes payments: checkout happens on the seller’s own page, usually Stripe.
What does the ✓ next to a creator’s name mean?
It means we confirmed the identity of the person behind the listing. It says nothing about the code itself — always check a build before installing it.
