Getting Better Reviews

Provide Context

Include related files and history:

CopyReview @src/api/payments.ts

Context:
- @src/types/payment.ts (types)
- @src/services/stripe.ts (integration)
- This replaces the old PayPal flow
- Must handle refunds within 30 days

Specify Your Concerns

CopyReview @src/auth/session.ts

I'm specifically worried about:
1. Race conditions in token refresh
2. Session fixation attacks
3. Memory leaks from unclosed sessions

Less concerned about:
- Code style (will run linter)
- Test coverage (separate pass)

Request Actionable Feedback

CopyReview @src/utils/parser.ts

For each issue found:
1. Explain the problem
2. Show the problematic code
3. Provide a fix
4. Rate severity

Review Output Format

Request structured output for complex reviews:

CopyReview @src/api/ and format findings as:

## Critical
- [Issue]: [Location]: [Description]

## Improvements
- [Suggestion]: [Location]: [Benefit]

## Questions
- [Question]: [Context]

## Positive
- What's done well

Iterative Reviews

Multi-Pass Approach

Copy# Pass 1: High-level
Review @src/orders/ for architectural issues.
Don't look at implementation details yet.

# Pass 2: After addressing Pass 1
Now review the implementation in @src/orders/service.ts
Focus on business logic correctness.

# Pass 3: Final
Security and performance review of @src/orders/

Review and Fix

CopyReview @src/api/upload.ts for security issues.

For each critical issue:
1. Explain it
2. Fix it immediately
3. Add a test case

Thinking Keywords for Reviews
