			`Fetch latest runtime errors from the sandbox error storage. These are errors captured by the runtime error detection system.

**IMPORTANT CHARACTERISTICS:**
- Runtime errors are USER-INTERACTION DRIVEN - they only appear when users interact with the app
- Errors may be a few seconds stale (not real-time)
- Errors persist in storage until explicitly cleared

**BEST PRACTICE WORKFLOW:**
1. Call this tool to see what runtime errors exist
2. If you make fixes and deploy changes (deploy_preview)
3. Use wait(20-30) to allow time for user interaction
4. Call get_runtime_errors again to verify errors are resolved

**When to use:**
- To see what runtime errors users have encountered
- After deploying fixes to verify issues are resolved
- To understand error patterns in the application

**When NOT to use:**
- Immediately after deploy (errors need user interaction to generate)
- In rapid succession (errors update on user interaction, not continuously)`,
