## Suggested prompts
### New install

```text
I downloaded a skill package from Yavira. Read SKILL.md from the extracted folder and install it by following the included instructions. Tell me what you changed and call out any manual steps you could not complete.
```
### Upgrade existing

```text
I downloaded an updated skill package from Yavira. Read SKILL.md from the extracted folder, compare it with my current installation, and upgrade it while preserving any custom configuration unless the package docs explicitly say otherwise. Summarize what changed and any follow-up checks I should run.
```

## Documentation

### Before Generating

Choose correct type — URL is not the only option. See types.md for vCard, WiFi, email, SMS, geo, etc.
Shorten dynamic URLs — Long URLs = dense codes = harder to scan. Use short links for tracking too.
Set error correction — L (7%) for clean environments, M (15%) default, Q (25%) with logos, H (30%) for harsh conditions

### Sizing Rules

Minimum sizes by scan distance:

Phone at arm's length (~30cm): 2x2 cm minimum
Table tent (~50cm): 3x3 cm
Poster (~1m): 5x5 cm
Billboard (~5m): 25x25 cm

Formula: QR size = scan distance ÷ 10

### Color & Contrast

Minimum 70% contrast between foreground and background
Dark on light ONLY — scanners expect dark modules
Never invert (white on black fails on many readers)
Avoid gradients on modules — solid colors only
Background can have subtle texture if contrast maintained

### Testing Checklist

Before printing/deploying:

Scan with 3+ different phones (iOS, Android old/new)
 Test in target lighting conditions
 Verify destination loads correctly
 Check at actual print size, not screen preview
 Test after any logo/customization applied

### Common Failures
