qr-code

Skill1 starsChanged 6 months agoMITView on GitHub

Generate accurate, phone-scannable QR codes as PNG or SVG from URLs, local preview links, text, contact/payment/event/Wi-Fi payloads, or shareable deliverables. Use automatically when Codex decides a user may need to scan with a phone, when a generated website/app/art/design/social asset/demo needs a QR code, when sharing localhost/tunnel/public links, or when the user asks for QR, qrcode, QR code, QR 碼, 二維碼, or 手機掃描. Prefer scripts/make_qr.py for deterministic local generation; ask before encoding secrets, private tokens, or sensitive personal data.

Their own version: similar meaning, or, weakest, the same name. We can’t tell which project had it first. Projects are counted among the 200 most-starred candidates, and mentions are links to the repository we found, up to 50 per site, so both counts are a floor.

The file

We split this skill into the rules it gives an agent

11 rules. 0 are common, 6 are distinctive, and 5 are very specific to this project.

  • 0

    Common

    Most of the 3 edited versions we read keep these.

  • 6

    Distinctive

    This author's own choices. Worth a look.

  • 5

    Very specific

    Tied to their project's names, files or tools. Probably skip.

  • Common
  • Distinctive
  • Very specific
  1. Very specific:

    Use scripts/make_qr.py to generate QR codes locally without web APIs or external packages.

    line 10
  2. Distinctive:

    Do not encode API keys, private tokens, passwords, or sensitive personal data unless the user explicitly asks for that payload.

    line 15
  3. Distinctive:

    Use PNG for previews, screenshots, social posts, and general user-facing assets.

    line 18
  4. Distinctive:

    Use SVG for print, design tools, websites, and scalable artwork.

    line 19
  5. Very specific:

    Default to error correction M for ordinary URLs and short text.

    line 23
  6. Very specific:

    Use Q for print, posters, stickers, or image-heavy layouts.

    line 24
  7. Very specific:

    Use H when a designer may recolor, overlay a logo, crop tightly, or place the code on busy artwork.

    line 25
  8. Very specific:

    Keep quiet zone at 4 modules or more.

    line 26
  9. Distinctive:

    Run the script from the skill directory:

    line 28
  10. Distinctive:

    If the QR points to a website, verify the target URL itself is reachable before presenting the QR as final.

    line 45
  11. Distinctive:

    When possible, open or inspect the generated image to ensure the quiet zone is visible and the modules are crisp.

    line 46

“Common” is measured: kept by at least 6 in 10 of the 3 edited versions of this file we could read. “Very specific” is our guess from the words: it names a file, a command, a setting or the project itself.

Keep what fits and drop the rest. Your version, ready for your agents.

QR Code

Core Workflow

Use scripts/make_qr.py to generate QR codes locally without web APIs or external packages.

  1. Confirm the exact payload to encode.
    • For websites and apps, encode the final reachable URL.
    • For phone scanning, avoid localhost unless the user explicitly wants a same-machine test. Use a public, tunnel, or LAN URL when the phone must open it.
    • Do not encode API keys, private tokens, passwords, or sensitive personal data unless the user explicitly asks for that payload.
  2. Choose output for the deliverable.
    • Use PNG for previews, screenshots, social posts, and general user-facing assets.
    • Use SVG for print, design tools, websites, and scalable artwork.
    • Generate both PNG and SVG when the QR code may be reused in design or publishing work.
  3. Choose scan settings.
    • Default to error correction M for ordinary URLs and short text.
    • Use Q for print, posters, stickers, or image-heavy layouts.
    • Use H when a designer may recolor, overlay a logo, crop tightly, or place the code on busy artwork.
    • Keep quiet zone at 4 modules or more. Do not crop it away.
  4. Run the script from the skill directory:
python .\scripts\make_qr.py "https://example.com" --output ".\out\example.png" --error-correction M --scale 10 --print-json

For SVG:

python .\scripts\make_qr.py "https://example.com" --output ".\out\example.svg" --format svg --error-correction Q --print-json

Verification

After generation:

  • Confirm the output file exists and is non-empty.
  • If the QR points to a website, verify the target URL itself is reachable before presenting the QR as final.
  • When possible, open or inspect the generated image to ensure the quiet zone is visible and the modules are crisp.
  • Report the encoded payload, output path, format, and error correction level.

Script Notes

scripts/make_qr.py is a pure Python QR generator. It supports byte-mode QR codes, automatic QR version selection, Reed-Solomon error correction, mask scoring, PNG output, and SVG output. It intentionally avoids online QR services so generated assets are private, fast, and reproducible.
