Greptile Overview

Summary

Increased function execution timeout from 5-10 seconds to 3 minutes (180s) across all execution paths to support longer-running user code

Key Changes:

• Route handler: maxDuration 60s → 300s, default timeout 5s → 180s
• Function handler: default timeout 5s → 180s
• Tool config: DEFAULT_TIMEOUT 10s → 180s

Issues Found:

• Critical: maxDuration (300s) exceeds execution timeout (180s), creating a 2-minute gap where the route stays open but execution has timed out

Confidence Score: 3/5

• This PR has a configuration mismatch that needs to be resolved before merging
• The changes correctly increase timeouts consistently across the codebase, but there's a logical error where maxDuration (300s) is set higher than the execution timeout (180s). This means functions will timeout at 3 minutes but the API route stays open for 5 minutes, potentially causing confusing behavior or resource waste.
• apps/sim/app/api/function/execute/route.ts - maxDuration and timeout values need alignment
