Baseline Targets

• Simple workflows: <100ms (well within range)
• Complex workflows: <500ms (well within range)
• MCP-heavy workflows: <1s (well within range)
• ExtractWorkflowNameFromFile is a CLI helper, no explicit target — but regression threshold is 10%

🔍 Context

This benchmark measures how quickly the CLI extracts workflow names from file paths. A regression here could impact workflows that enumerate or reference workflow files by name.

Note: this comparison is based on 1 historical data point — while the threshold has been crossed (+19.8% > 10%), it should be monitored over the next few runs to confirm this is a real regression and not measurement noise.

💡 Recommended Actions

1. Review recent changes to the workflow name extraction logic in pkg/cli/ or pkg/workflow/
2. Run go test -v -run "TestExtractWorkflowName" ./pkg/cli/ to verify correctness
3. Run go test -bench=BenchmarkExtractWorkflowNameFromFile ./pkg/cli/ -benchtime=10s for a more stable measurement
4. Compare with previous benchmark results using benchstat
