Pull Request Review

Summary

This PR correctly updates the README examples to use the proper flag --use-receiver-type instead of the deprecated --receiver-type, and adds a helpful reference to the command tests as additional examples.

✅ Code Quality & Best Practices

Excellent work! The changes are:

• Accurate: The flag update from --receiver-type to --use-receiver-type is correct according to docs/reference/cli.md:91-92
• Consistent: All three instances in the README have been updated (lines 42, 81)
• Clear: The new examples section reference helps users discover the test fixtures as learning resources

✅ Correctness Verification

Verified against the codebase:

• --use-receiver-type is the current canonical flag (internal/cli/commands.go:365)
• --receiver-type is deprecated (internal/cli/commands.go:382, docs/reference/cli.md:91)
• All documentation and test files use --use-receiver-type consistently
• The command tests reference (./cmd/muxt/testdata) is valid and contains 50+ test examples

✅ Documentation Improvement

The addition of the test examples link is a valuable improvement:

• Provides concrete, runnable examples for users
• Aligns with the project's test-driven approach
• Uses appropriate qualifying language ("were intended to be readable examples")

No Issues Found

• ✅ Security: No security concerns (documentation-only change)
• ✅ Performance: No performance impact (documentation-only change)
• ✅ Test Coverage: N/A (documentation-only change)
• ✅ Breaking Changes: None (maintains backward compatibility - old flag still works with deprecation warning)
• ✅ Potential Bugs: None identified

Minor Observations

1. Consistency check: All other documentation already uses --use-receiver-type, so this brings the README in line with the rest of the project
2. User impact: Positive - helps users avoid using deprecated flags from the start

Recommendation

Approve and merge. This is a clean, focused documentation fix that improves accuracy and user experience.
