Greptile Overview

Summary

This PR implements consistency improvements for trigger block handling in the workflow system. The changes standardize how trigger blocks are created and identified throughout the application by making two key modifications:

1. Consistent UUID Generation: The workflow creation code now uses crypto.randomUUID() instead of timestamp-based IDs (${triggerId}_${Date.now()}) when creating trigger blocks. This ensures all blocks use the same ID format regardless of whether they're created through the toolbar or trigger list, resolving inconsistencies with sidebar selection behavior.

2. Trigger Block Identification: All core trigger blocks (ApiTriggerBlock, ChatTriggerBlock, InputTriggerBlock, ManualTriggerBlock, and ScheduleBlock) now include a triggerAllowed: true property in their configuration. This flag serves as a standardized way to identify which blocks can function as workflow triggers, providing better context for copilot functionality and system-wide trigger handling.

These changes integrate well with the existing block configuration system, following the same patterns used elsewhere in the codebase. The BlockConfig type already supports the optional triggerAllowed property, and other block creation methods throughout the workflow file already use crypto.randomUUID(), making this a natural alignment with established conventions.

apps/sim/blocks/blocks/manual_trigger.ts	5/5	Added triggerAllowed: true flag to ManualTriggerBlock configuration for trigger categorization
apps/sim/blocks/blocks/api_trigger.ts	5/5	Added triggerAllowed: true flag to ApiTriggerBlock configuration for proper trigger identification
apps/sim/blocks/blocks/input_trigger.ts	5/5	Added triggerAllowed: true flag to InputTriggerBlock configuration to align with other triggers
apps/sim/app/workspace/[workspaceId]/w/[workflowId]/workflow.tsx	5/5	Replaced timestamp-based ID generation with crypto.randomUUID() for trigger block creation consistency

Confidence score: 5/5

• This PR is safe to merge with minimal risk as it implements straightforward consistency improvements
• Score reflects simple, well-aligned changes that follow existing codebase patterns and conventions
• No files require special attention as all changes are minor configuration additions and standard library usage
