📋 Review Summary

This PR fixes serverless functionality to properly read the x-rivet-token header from the start endpoint. The changes are minimal and focused, which is good for a bug fix.

✅ Positive Aspects

1. Focused Fix: The changes are minimal and directly address the issue without unnecessary modifications
2. Type Safety: Proper TypeScript parameter typing for the token parameter
3. Header Constants: Good use of existing header constant x-rivet-token from actor-router-consts.ts:21
4. Conditional Logic: Smart conditional token override only when a token is provided

🔍 Detailed Analysis

File: packages/rivetkit/src/manager/router.ts

• Line 108: Function signature updated to accept token parameter ✅
• Line 121: Correctly reads x-rivet-token header and passes to builder ✅
• Lines 172-174: Incidental formatting change (good) ✅

File: packages/rivetkit/src/registry/mod.ts

• Line 218: Function signature matches router change ✅
• Lines 219-220: Conditional token override logic is sound ✅

🔐 Security Considerations

• Token Handling: The token is properly passed through the request header x-rivet-token which is already defined in the allowed public headers (actor-router-consts.ts:58) ✅
• No Exposure: Token is not logged or exposed in the codebase ✅
• Conditional Override: Only overrides config when token is explicitly provided ✅

⚡ Performance Considerations

• Minimal Overhead: The header read operation has negligible performance impact ✅
• No Memory Leaks: No additional object creation or retention concerns ✅

🧪 Test Coverage Assessment

Observation: No specific tests found for serverless token handling functionality. However, this is a relatively simple fix that:

• Reads a header value (standard Hono operation)
• Passes it to an existing function
• Conditionally assigns a config value

Recommendation: Consider adding integration tests for serverless scenarios with token authentication, but the current change is low-risk.

🏗️ Code Quality

• Follows Project Guidelines: Adheres to CLAUDE.md conventions ✅
• Type Safety: Proper TypeScript usage ✅
• Error Handling: Leverages existing error handling patterns ✅
• Code Style: Consistent with existing codebase ✅

📝 Minor Observations

1. The incidental formatting change in router.ts (lines 172-174) appears to be an IDE auto-format - this is fine and improves consistency
2. The logic correctly handles undefined tokens by only overriding when explicitly provided

🎯 Overall Assessment

APPROVED ✅ This is a well-implemented bug fix that:

• Solves the stated problem
• Maintains type safety
• Follows security best practices
• Has minimal risk of introducing new bugs
• Adheres to project conventions

The changes are production-ready and should be safe to merge.

This PR fixes serverless functionality to properly read the x-rivet-token header from the start endpoint. The changes are minimal and focused, which is excellent for a bug fix.

✅ Positive Aspects

1. Focused Fix: The changes are minimal and directly address the issue without unnecessary modifications
2. Type Safety: Proper TypeScript parameter typing for the token parameter
3. Header Constants: Good use of existing header constant HEADER_RIVET_TOKEN from actor-router-consts.ts:21
4. Conditional Logic: Smart conditional token override only when a token is provided
5. Security Compliance: Token is properly handled via secure headers as documented in the constants file

🔍 Detailed Analysis

File: packages/rivetkit/src/manager/router.ts

• Line 108: Function signature updated to accept optional token parameter ✅
• Line 121: Correctly reads x-rivet-token header using c.req.header() and passes to builder ✅
• Clean implementation that follows existing patterns in the codebase

File: packages/rivetkit/src/registry/mod.ts

• Line 218: Function signature matches router change with proper typing ✅
• Lines 219-220: Sound conditional token override logic - only overrides when token is explicitly provided ✅
• Maintains existing config structure while allowing token override

🔐 Security Considerations

• Token Handling: The token is properly passed through the request header x-rivet-token which is already defined in the allowed public headers (actor-router-consts.ts:58) ✅
• No Exposure: Token is not logged or exposed in the codebase ✅
• Conditional Override: Only overrides config when token is explicitly provided, preventing unintentional token clearing ✅
• Secure Transport: Uses headers rather than URL parameters as recommended in the constants file comments ✅

⚡ Performance Considerations

• Minimal Overhead: The header read operation has negligible performance impact ✅
• No Memory Leaks: No additional object creation or retention concerns ✅
• Lazy Evaluation: Token is only processed when provided ✅

🧪 Test Coverage Assessment

Observation: This is a relatively simple fix with low complexity:

• Reads a header value (standard Hono operation)
• Passes it to an existing function
• Conditionally assigns a config value

Recommendation: While the current change is low-risk, consider adding integration tests for serverless scenarios with token authentication to ensure the fix works end-to-end.

🏗️ Code Quality

• Follows Project Guidelines: Adheres to CLAUDE.md conventions ✅
• Type Safety: Proper TypeScript usage with optional parameter typing ✅
• Error Handling: Leverages existing error handling patterns ✅
• Code Style: Consistent with existing codebase formatting and patterns ✅
• Import Usage: Correctly uses existing constants rather than hardcoding strings ✅

📝 Minor Observations

1. The function parameter correctly uses string | undefined typing, which is appropriate for optional header values
2. The logic properly handles undefined tokens by only overriding when explicitly provided
3. No breaking changes to existing API surface

🎯 Overall Assessment

APPROVED ✅ This is a well-implemented bug fix that:

• Solves the stated problem elegantly
• Maintains type safety throughout
• Follows security best practices
• Has minimal risk of introducing new bugs
• Adheres to project conventions
• Uses existing infrastructure appropriately

The changes are production-ready and should be safe to merge. The implementation is clean, focused, and follows established patterns in the codebase.
