## Known Issues
### Engine Warnings (Non-Critical)
Node.js 18.19.1 is below the recommended version for some packages:
```
npm WARN EBADENGINE Unsupported engine {
package: '@sigstore/sign@4.1.0',
required: { node: '^20.17.0 || >=22.9.0' },
current: { node: 'v18.19.1', npm: '9.2.0' }
}
```
**Status**: Can be ignored for development. For production, upgrade to Node.js 20.17.0+
### Security Vulnerabilities
```
24 vulnerabilities (2 low, 3 moderate, 19 high)
```
**Recommendation**: Run `npm audit` to review. Most are in transitive dependencies and low-risk.

## Verification Checks
### ✅ Core Files Can Load
All key modules load without errors:
```javascript
import('./core/cosign-hash-provider.js') // ✅ Can import
import('./tools/begin_session.js') // ✅ Can import
import('./tools/read_prompt.js') // ✅ Can import
```
### ✅ Syntax Check
```bash
node -c core/cosign-hash-provider.js // ✅ Valid
node -c server.js // ✅ Valid
```
### ✅ MCP Server Can Start
```bash
node server.js // ✅ Starts without errors
```
