Kaboom Performance
Use this skill for performance triage, regression checks, and optimization validation.
Inputs To Request
- Feature or page URL
- Baseline branch or expected budget
- Critical user journey steps
- Success budget (for example LCP, TTI, or API latency)
Workflow
-
Define scenario:
List exact navigation and interaction sequence.
-
Capture baseline:
Collect network waterfall, web vitals, and action timeline.
-
Run candidate path:
Repeat the same sequence and collect the same artifacts.
-
Compare deltas:
Report largest regressions by metric and by request.
-
Prioritize fixes:
Call out top bottleneck, likely cause, and lowest-risk optimization.
