Greptile Overview

Greptile Summary

This PR increases execution timeouts across the platform from conservative values (5s-3min) to a consistent 10-minute timeout for long-running operations.

Key Changes:

• DEFAULT_FUNCTION_TIMEOUT: 5s → 600s (for custom tool code execution in agent blocks)
• REQUEST_TIMEOUT: 120s → 600s (for LLM API requests in agent blocks)
• DEFAULT_EXECUTION_TIMEOUT_MS: 180s → 600s (for function block code execution)
• Removed unused MAX_EXECUTION_DURATION constant (was used for API route duration with buffer, no longer referenced)
• Cleaned up unused timeout and validateStatus parameters from HTTP request tool (these were never implemented in the execution logic)

Impact:
The changes allow workflows with complex custom tools, long-running code, or slow LLM responses to complete successfully instead of timing out prematurely. The HTTP parameter cleanup removes dead code without affecting functionality since these parameters were never actually used in request execution.

Confidence Score: 5/5

• This PR is safe to merge with minimal risk
• The changes are straightforward constant adjustments that increase timeout values to accommodate longer-running operations. The removed code (MAX_EXECUTION_DURATION, HTTP timeout/validateStatus params) was confirmed to be unused throughout the codebase. All modifications maintain backward compatibility since they only extend execution windows without changing behavior or breaking existing functionality.
• No files require special attention
