A formal specification system that automatically analyzes code changes and generates comprehensive formal specifications using advanced LLM techniques and Lean4 theorem proving.
SpecSync is a GitHub App that provides end-to-end formal verification capabilities from GitHub integration to developer feedback loops, featuring advanced security analysis, performance guarantees, and comprehensive theorem proving.

specsync# Railway/Heroku deployment
railway up
# or
heroku create specsync-app
git push heroku main// The system now generates comprehensive specifications including:
{
"preconditions": [
"All input parameters are valid and non-null",
"Authentication and authorization are verified",
"Input validation passes all security checks"
],
"postconditions": [
"Function completes execution successfully",
"Return value matches expected type",
"No information leakage occurs",
"Resources are properly cleaned up"
],
"complexity": {
"time": "O(n)",
"space": "O(1)"
},
"security": {
"vulnerabilities": [
"Potential input validation bypass",
"Possible information disclosure"
],
"mitigations": [
"Implement strict input validation",
"Use parameterized queries"
]
},
"confidence": 0.85,
"rationale": "Function modifies critical state and requires comprehensive validation"
}# Run the complete UI demo
npm run ui-demo
# Start the web dashboard
npm run dashboard
# Generate VSCode extension
node -e "const { VSCodeUI } = require('./src/vscode-ui'); new VSCodeUI().generateVSCodeExtension();"The UI framework provides comprehensive components across all surfaces:
- GitHub Integration: Spec comments, coverage badges, proof check sidebar
- VSCode Plugin: Inline annotations, suggestion panel, proof runner
- Web Dashboard: Coverage maps, drift monitoring, audit explorer
- Slack Alerts: Drift notifications, proof failure alerts
- Design Principles: Height constraints, confidence transparency, progressive enhancement
