Critical Bug Detector

This skill prevents the disasters that happened in v1.0.95-96 where critical files were missing from releases.

When This Skill Activates

• Building an installer or preparing a release
• Modifying installer configuration files (.iss)
• Working on packaging or distribution
• After significant changes to project structure

Critical Checks Performed

1. Whisper Model Verification ⚠️ CRITICAL

Check ggml-tiny.bin (FREE tier model - MUST be in installer)

# File exists and correct size
test -f "VoiceLite/whisper/ggml-tiny.bin" || FAIL "Missing ggml-tiny.bin!"
size=$(stat -c%s "VoiceLite/whisper/ggml-tiny.bin" 2>/dev/null)
[ "$size" -eq 44048314 ] || WARN "ggml-tiny.bin size incorrect (expected 42MB)"

# Not ignored by git (v1.0.96 bug)
git check-ignore VoiceLite/whisper/ggml-tiny.bin && FAIL "Model ignored by git!"

# Included in installer script
grep -q "ggml-tiny.bin" VoiceLite/Installer/VoiceLiteSetup.iss || FAIL "Model not in installer!"

Check whisper.exe

# Executable present
test -f "VoiceLite/whisper/whisper.exe" || FAIL "Missing whisper.exe!"

# Verify size (whisper.cpp v1.7.6)
expected_size=480256
actual_size=$(stat -c%s "VoiceLite/whisper/whisper.exe" 2>/dev/null)
[ "$actual_size" -eq "$expected_size" ] || WARN "whisper.exe size mismatch (expected 469KB, got $(($actual_size / 1024))KB)"

# Verify SHA256 (v1.7.6)
expected_hash="b7c6dc2e999a80bc2d23cd4c76701211f392ae55d5cabdf0d45eb2ca4faf09af"
actual_hash=$(sha256sum VoiceLite/whisper/whisper.exe | cut -d' ' -f1)
[ "$actual_hash" = "$expected_hash" ] || WARN "whisper.exe hash mismatch - binary may have been modified!"

2. Version Consistency Check

All these files must have matching version numbers:

• VoiceLite/VoiceLite/VoiceLite.csproj → <Version>X.X.X</Version>
• VoiceLite/Installer/VoiceLiteSetup.iss → AppVersion=X.X.X
• voicelite-web/package.json → "version": "X.X.X"
• voicelite-web/app/api/download/route.ts → Default download version

3. Build Configuration Check

Debug vs Release Mode

// WARNING: Building installer in Debug mode
// Check: VoiceLite.csproj should use Release configuration

// CRITICAL: Logging suppressed in Release (v1.0.94 bug)
// Verify: ErrorLogger doesn't have #if !DEBUG blocks

4. Dependency Verification

Required files in installer:

• VoiceLite.exe (main application)
• ggml-tiny.bin (42MB - free model)
• whisper.exe (transcription engine)
• VC++ Runtime installers
• All required DLLs

5. Git State Check

# Uncommitted critical files
git status --porcelain | grep -E "(\.iss|\.csproj|package\.json)" && WARN "Uncommitted version files"

# Tag exists for this version
version=$(grep -oP '(?<=<Version>)[^<]+' VoiceLite/VoiceLite/VoiceLite.csproj)
git tag | grep -q "v$version" && WARN "Tag v$version already exists"

Action Items Generated

When issues are detected:

1. Missing Model File → Add to git, update installer script
2. Version Mismatch → List all locations needing update
3. Debug Mode → Switch to Release configuration
4. Git Issues → Commit changes before building

Historical Context

v1.0.95-96 Disaster: ggml-tiny.bin was in .gitignore, causing installer to ship without the model. This resulted in 100% failure rate for new installations.

v1.0.94 Bug: Logging was suppressed in Release builds with #if !DEBUG, making production debugging impossible.

Quick Pre-Release Checklist

Before building installer:

1. Model file exists: VoiceLite/whisper/ggml-tiny.bin (42MB)
2. Model not in .gitignore
3. Whisper.exe present and correct hash
4. All version files match (.csproj, .iss, package.json)
5. Building in Release mode (not Debug)
6. No uncommitted version changes
7. Installer script includes all required files
