feat: Implement lpop ask command for requesting environment variables

[tombeckenham]

Summary

• Implements lpop ask command from issue [Feature] lpop ask #46
• Generates shareable messages with quantum public keys for secure env var requests
• Auto-copies messages to clipboard for easy sharing in Slack/Discord/Teams

Key Features

• 🎭 20 quirky message templates with personality and emojis
• 🔐 Post-quantum security using existing ML-KEM768 keys from [Feature] Device Public Private Key #45
• 📋 Auto-clipboard copy with cross-platform clipboardy support
• 🎯 Clean repository display shows owner/repo instead of internal service names
• 🌍 Universal compatibility - plain text format works everywhere

Implementation Details

• New files: src/ask-messages.ts, tests/ask-messages.test.ts
• Enhanced files: src/cli.ts with new ask command handler
• Dependencies: Added clipboardy as dev dependency (compiled CLI)
• Display improvements: All CLI commands now show clean owner/repo format to users

Example Usage

$ lpop ask -e production
✓ Message copied to clipboard!

# Generated message:
🚀 Mission control, requesting these variables for launch:

Repository: loggipop/lpop [production]

lpop give {quantum-public-key}

Testing

• ✅ Unit tests for message generation and formatting
• ✅ Integration tests for CLI ask command
• ✅ Manual testing across different repository contexts
• ✅ Cross-platform clipboard functionality verified

Breaking Changes

None - this is a new feature that doesn't affect existing functionality.

Code Review Complete ✅

I've thoroughly reviewed PR #52 implementing the lpop ask command. Overall, this is a well-implemented feature with good security practices and comprehensive testing.

Todo List:

• Read repository guidelines (CLAUDE.md)
• Analyze new ask-messages.ts implementation
• Review CLI changes in src/cli.ts
• Examine test coverage and quality
• Check package.json dependencies
• Assess security considerations
• Evaluate performance implications
• Provide comprehensive feedback

---

✅ Strengths

Code Quality & Architecture

• Clean separation of concerns: The ask-messages.ts module is well-isolated with a clear, focused API
• Consistent error handling: All CLI commands follow the established pattern with proper error catching and chalk coloring
• Type safety: Good use of TypeScript with proper interfaces and type annotations
• Following existing patterns: The new command integrates seamlessly with the existing CLI architecture

Security Implementation

• Post-quantum cryptography: Excellent use of ML-KEM768 from @noble/post-quantum for future-proof security
• Proper key management: Device keys are properly generated, stored with expiration (7 days), and automatically cleaned up
• No sensitive data exposure: Public keys only are shared in the generated messages
• Secure clipboard handling: Uses established clipboardy library

Test Coverage

• Comprehensive unit tests: The ask-messages.test.ts file covers all core functionality including edge cases
• Integration testing: CLI tests properly mock dependencies and test the complete flow
• Good test practices: Tests are well-structured with descriptive names and proper assertions

🔍 Areas for Consideration

Minor Code Quality Issues

1. Hardcoded message count (src/ask-messages.ts:32):

   const randomIndex = Math.floor(Math.random() * ASK_MESSAGES.length);

   ✅ Actually good - this correctly uses the array length, not hardcoded

2. Error handling in clipboard operations (src/cli.ts:546):

   • Consider adding specific error handling for clipboard failures, as this could fail on headless systems or with clipboard access issues

Security Considerations

3. Public key format validation (src/ask-messages.ts:39-51):

   • The formatAskMessage function doesn't validate the public key format
   • Consider adding basic validation to ensure the key looks like a valid base58-encoded string

4. Service name sanitization (src/cli.ts:540):

   • The service name from git parsing is displayed directly - consider sanitizing to prevent any display formatting issues

Performance & UX

5. Random seed predictability:

   • The random message selection uses Math.random() which is fine for this use case (fun messages)
   • Not a security issue since message selection doesn't need cryptographic randomness

6. Clipboard feedback (src/cli.ts:546-557):

   • Great UX with the clipboard copy confirmation and message preview
   • Consider adding a fallback message if clipboard access fails

📝 Detailed Technical Review

New Files Analysis

src/ask-messages.ts:

• Well-structured with 20 quirky, professional messages
• Good function separation with getRandomAskMessage() and formatAskMessage()
• Messages strike the right balance between fun and professional
• Template structure is clean and consistent

tests/ask-messages.test.ts:

• Excellent test coverage including randomness validation
• Tests verify emoji presence, message structure, and proper formatting
• Edge cases covered (environment vs no environment)

Modified Files Analysis

src/cli.ts (Lines 139-148, 527-566):

• New ask command integrates perfectly with existing commander.js structure
• Proper options inheritance from global CLI options
• Good error handling with chalk-colored output
• Clean integration with quantum key system

package.json:

• clipboardy is appropriately added as devDependency (following repo pattern for compiled CLI)
• No unnecessary dependencies introduced

🚀 Performance & Scalability

• Minimal performance impact: New command only loads when explicitly called
• Efficient clipboard operation: Single clipboard write operation
• Lazy loading: Dependencies only loaded when needed

🔒 Security Assessment

• Strong cryptographic foundation: ML-KEM768 provides quantum resistance
• Proper key lifecycle: Keys expire in 7 days and are auto-cleaned
• No credential exposure: Only public keys are ever shared
• Safe message content: All message templates are static and safe

📊 Test Quality Analysis

The test suite demonstrates excellent practices:

• Unit test isolation: Proper mocking of external dependencies
• Integration testing: CLI commands tested end-to-end
• Edge case coverage: Environment parameters, error states
• Randomness validation: Ensures message variety without being flaky

🎯 Recommendations

High Priority (Security/Functionality)

1. Add clipboard error handling with graceful fallback
2. Consider basic public key format validation

Medium Priority (Code Quality)

3. Add input sanitization for service names displayed to users
4. Consider adding a --dry-run option to preview messages without clipboard

Low Priority (Enhancement)

5. Consider allowing custom message templates via config file
6. Add metrics/analytics for message template popularity (if desired)

📋 Final Assessment

This PR successfully implements the requested feature with:

• ✅ Security: Strong post-quantum cryptography
• ✅ User Experience: Fun, professional messages with auto-clipboard
• ✅ Code Quality: Clean, well-tested, follows established patterns
• ✅ Integration: Seamlessly fits existing CLI architecture
• ✅ Testing: Comprehensive coverage with good practices

Overall: Excellent work! This feature is ready for merge. The implementation is secure, well-tested, and provides great user experience. The post-quantum cryptography integration is particularly impressive.
