Task Handlers improvements

[fblgit]

This PR:

• fix: task.update - allow project tasks to have a more flexible status transition from completed
• fix: task.list - show attachment.result for tasks (known as metadata.result)
• enhance: task.list - less timestamp fields: optional createdAt, completedAt, updatedAt

Code Review for Task Handlers improvements

I've reviewed the changes in PR #20. Overall, the implementation is solid and follows the project's architectural patterns well. Here's my detailed feedback:

✅ Strengths

1. Good adherence to project conventions: The code follows CLAUDE.md guidelines including:

   • Atomic Redis operations via Lua scripts
   • Schema-first development with proper Zod validation
   • Proper event naming conventions
   • Appropriate handler structure under 50 lines

2. Comprehensive test coverage: The new contract tests in task.update.contract.test.ts thoroughly cover:

   • Project task transitions (lines 189-223)
   • Regular task blocking (lines 252-284)
   • Edge cases with different metadata configurations

3. Smart feature design: The project task flexibility (allowing completed tasks to transition back) makes sense for complex workflows while maintaining integrity for regular tasks.

🔍 Code Quality & Best Practices

1. lua-scripts.ts (lines 637-644):

   • Clean implementation checking for project tasks via metadata
   • Good use of existing Lua patterns
   • Properly preserves backward compatibility

2. task.list.handler.ts (lines 78-135):

   • Efficient parallel fetching with Promise.all
   • Good error handling with silent failures for non-critical attachment info
   • Smart limiting of attachment keys to prevent response bloat (line 101)

3. task.schema.ts (lines 155-160):

   • Well-structured optional schema additions
   • Proper use of .nullable().optional() pattern

⚠️ Potential Issues & Suggestions

1. Performance Consideration in task.list.handler.ts:

   • Line 92: The query ctx.prisma.taskAttachment.findMany is executed for each task in the result set
   • Impact: With 100 tasks (default limit), this creates 100 additional DB queries
   • Suggestion: Consider using a single query with WHERE taskId IN [...taskIds] and then grouping results in memory:

   const allAttachments = await ctx.prisma.taskAttachment.findMany({
     where: { taskId: { in: tasks.map(t => t.id) } },
     select: { taskId: true, key: true, type: true, value: true, content: true, createdAt: true }
   });
   const attachmentsByTask = allAttachments.reduce((acc, att) => {
     if (!acc[att.taskId]) acc[att.taskId] = [];
     acc[att.taskId].push(att);
     return acc;
   }, {});

2. Redis Connection Usage in task.list.handler.ts:

   • Line 88: Uses ctx.redis.pub.zcard - ensure this is the intended Redis connection
   • The project typically uses ctx.redis directly, not .pub

3. Schema Documentation:

   • The new resultAttachment field in taskListOutput could benefit from a comment explaining its purpose
   • Consider adding JSDoc comments for better API documentation

🔒 Security Review

• ✅ No SQL injection risks (using Prisma ORM)
• ✅ No sensitive data exposure
• ✅ Proper input validation via Zod schemas
• ✅ No hardcoded secrets or credentials

📊 Performance Impact

• The N+1 query issue mentioned above could impact response times for large result sets
• Redis zcard operations are efficient (O(1))
• Consider implementing pagination limits to prevent excessive memory usage

✨ Minor Improvements

1. Type Safety: In task.list.handler.ts line 31, using any for the where clause:

   const where: any = {}; // Consider using Prisma.TaskWhereInput type

2. Magic Numbers: Line 101 has a hardcoded limit of 20:

   take: 20 // Consider extracting to a const MAX_ATTACHMENT_KEYS = 20

✅ Test Coverage

The test additions are excellent:

• Covers the new project task transition logic thoroughly
• Tests both positive and negative cases
• Validates the distinction between project tasks and regular tasks
• Good use of test data setup and cleanup

📝 Summary

The PR successfully implements the three stated objectives:

1. ✅ Flexible status transitions for project tasks
2. ✅ Shows attachment.result in task.list response
3. ✅ Makes timestamps optional (though I don't see explicit optional handling - they still appear in the response)

Recommendation: Approve with suggestions - the main concern is the potential N+1 query performance issue which should be addressed before high-volume usage.

Great work on maintaining consistency with the project's architecture and adding comprehensive tests! 🎉
