PR Review: Add RivetKit Driver Test Writer AgentSummaryThis PR adds a specialized Claude agent for writing, modifying, and debugging RivetKit driver tests. Overall, this is a well-structured agent definition that demonstrates good understanding of the testing framework and provides clear guidance. Below are my findings organized by category. Code Quality & Best Practices ✅Strengths:

Potential Issues 🔍
Performance Considerations ⚡
Security Concerns 🔒No security issues identified. This is an internal development tool. Test Coverage 📊The agent itself provides good coverage of testing scenarios in its examples:
However, it should clarify that most test writing will be in Alignment with CLAUDE.md 📋Good alignment:

Specific RecommendationsCritical Fixes Needed:
## RivetKit Test Architecture
- **Driver Test Files** (`tests/driver-*.test.ts`): Entry points that configure and run tests for specific drivers (engine, file-system, memory)
- **Test Suites** (`src/driver-test-suite/tests/*.ts`): Reusable, driver-agnostic test functions exported via `runActorStateTests()`, `runActorConnTests()`, etc.
- **Fixtures** (`fixtures/driver-test-suite/*.ts`): Actor implementations used as test subjects
### Test Execution
- Run specific driver tests: `cd rivetkit-typescript/packages/rivetkit && pnpm test tests/driver-{driver}.test.ts -t '{test filter}'`
- Available driver test files: `driver-engine.test.ts`, `driver-file-system.test.ts`, `driver-memory.test.ts`
- Filter by test suite name (e.g., "Actor State Tests", "State Persistence")
Minor Enhancements:
ConclusionThis is a solid foundation for a specialized testing agent. The main issues are around accurate representation of the test file structure and command execution patterns. Once the path clarifications and command corrections are made, this will be a very useful agent for RivetKit development. Recommendation: Request changes to fix the critical path and command issues before merging. |

PR Review: RivetKit Driver Test Writer AgentI've reviewed this PR which adds a specialized Claude Code agent for RivetKit driver test development. This is a well-crafted agent definition that will be valuable for the team. Here's my detailed analysis: ✅ Strengths
🔍 Issues Requiring AttentionCritical: Test Command FormatLines 29-32: The test execution command format needs correction. Currently states: cd rivetkit-typescript/packages/rivetkit && pnpm test driver-{driver} -t '{test filter}'However, based on cd rivetkit-typescript/packages/rivetkit && pnpm test tests/driver-engine.test.ts -t 'test name pattern'Available driver test files:
Minor: Terminology InconsistencyLine 36: The agent mentions using // Actual pattern from actor-sleep.ts:15

// ...
});Recommendation: Change "Use Vitest's 📋 Suggested Enhancements
🎯 Minor Corrections
🔒 Security & Performance
📊 Overall AssessmentThis is a valuable addition that will significantly help with RivetKit test development. The agent prompt is thorough and well-thought-out. The main issue is the test command format which needs correction before this agent can function properly. Recommendation: Approve with the understanding that the test command format should be corrected. The critical fix is straightforward and the rest of the agent is solid. Nice work on creating such a comprehensive agent definition! This will be very helpful for maintaining consistent test quality across the RivetKit driver implementations. |

Code Review: RivetKit Driver Test Writer AgentThank you for adding this specialized agent for RivetKit driver test development! This is a well-structured and comprehensive agent configuration. Here's my detailed review: ✅ Strengths
🔍 Issues & Suggestions1. Test Command Format Issue (Minor)Location: Line 28-29 The documented test command format appears incomplete: cd rivetkit-typescript/packages/rivetkit && pnpm test driver-{driver} -t '{test filter}'Issue: Based on the
Verification Needed:
Recommendation: Verify this command actually works and update the documentation accordingly. Consider adding a real working example. 2. Missing Fixture Import Patterns (Minor)Location: Line 62 (Fixture Actor Development section) The agent provides guidance on implementing fixtures but doesn't show:
From my review of import { actor } from "rivetkit";
export const connStateActor = actor({ ... });Recommendation: Add a brief example showing the fixture export pattern. 3. Test Isolation Guidance (Enhancement)Location: Line 44-47 (Test Structure Best Practices) While cleanup in
Recommendation: Add a subsection about RivetKit-specific cleanup patterns, especially for distributed resources. 4. Error Handling in Tests (Enhancement)The guide doesn't mention:
Recommendation: Add guidance on testing failure scenarios and error assertions. 5. Determinism in Distributed Systems (Clarification Needed)Location: Line 25 ("Resilient to timing issues in distributed systems") This is mentioned but not elaborated on. Given RivetKit's distributed nature:
Recommendation: Add a section on handling timing and race conditions in distributed tests. 🎯 RecommendationsHigh Priority:

📋 Code Quality Assessment
✅ Approval StatusConditional Approval - Please verify the test command format works correctly. If it does, this is ready to merge. If not, please update line 28-29 with the correct command syntax. 🧪 Suggested TestingBefore merging, please verify: cd rivetkit-typescript/packages/rivetkit
pnpm test driver-engine -t 'persists state'Should successfully run only the state persistence tests for the engine driver. Great work on this agent! The structure is solid and it will be very helpful for maintaining test quality across the RivetKit driver implementations. 🚀 |
Pull Request ReviewThis PR adds a specialized Claude agent for writing RivetKit driver tests. Here's my analysis: ✅ Strengths
🔍 Issues & Recommendations1. Test Command Syntax Needs CorrectionThe agent instructs to run tests with: cd rivetkit-typescript/packages/rivetkit && pnpm test driver-{driver} -t '{test filter}'However, based on the actual test structure, the correct command should be: cd rivetkit-typescript/packages/rivetkit && pnpm test tests/driver-{driver}.test.ts -t '{test filter}'Files to reference: The driver test files are located at:
Recommended fix: Update line 29 to use the correct file path pattern. 2. Missing Context About Test StructureThe agent should mention that:
This helps the agent understand the layered test architecture. 3. Logging Pattern AlignmentThe agent should reference the project's logging conventions from CLAUDE.md:
While this is Rust-specific, the TypeScript equivalent would be structured logging patterns if applicable. 4. Minor: Example Command EnhancementLine 32's example command could be improved: # Current
cd rivetkit-typescript/packages/rivetkit && pnpm test driver-engine -t 'workflow cancellation' > /tmp/test-output.log 2>&1 && grep -i 'error\|fail' /tmp/test-output.log
# Better (clearer separation of concerns)
cd rivetkit-typescript/packages/rivetkit && pnpm test tests/driver-engine.test.ts -t 'workflow cancellation' > /tmp/test-output.log 2>&1
grep -i 'error\|fail' /tmp/test-output.logThis aligns better with the project's testing guidelines about piping to files and grepping separately. 📋 Suggested Changes
🎯 Overall AssessmentThis is a valuable addition that will help guide test development for RivetKit. The agent provides comprehensive guidance and follows good documentation practices. With the command syntax corrections, this will be production-ready. Recommendation: Approve with minor corrections to the test command syntax. Review generated by Claude Code |
