Notes |
| On-topic |
✅ yes |
Performance regression fix in the workflow compiler — directly relevant to project quality |
| Follows process |
✅ yes |
Authored by Copilot coding agent, assigned to core team member pelikhan — exactly the workflow CONTRIBUTING.md prescribes |
| Focused |
✅ yes |
All 3 files address the same root cause: YAML library swap (goccy/go-yaml → go.yaml.in/yaml/v3) + benchmark warm-up to exclude one-time cache costs |
| New dependencies |
✅ no |
go.yaml.in/yaml/v3 is already a direct dependency in go.mod (v3.0.4); goccy/go-yaml remains in use across the wider codebase |
| Has tests |
✅ yes |
compiler_performance_benchmark_test.go updated with warm-up + b.ResetTimer() across all 6 benchmark functions |
| Has description |
✅ yes |
PR body contains a fully-checked task list with benchmark numbers (5.6 ms achieved vs 13.4 ms regressed, 7.4 ms historical target) |

Summary
This is a clean, well-scoped performance fix authored by the Copilot coding agent following the project's prescribed agentic development process. The two changes are tightly coupled — replacing the slower goccy/go-yaml YAML parser with the already-present go.yaml.in/yaml/v3 for schema validation paths, and correctly excluding one-time schema compilation overhead from all benchmark measurements with b.ResetTimer(). The PR body is thorough, all checklist items are marked complete, and tests/lint are confirmed passing. The only marker holding it back from merge is the [WIP] draft status, which the core team reviewer can clear once they're satisfied.
