Performance Planning Perspective

Use this skill only when the user explicitly asks for performance-focused planning.

Focus

Prioritize decisions that improve measurable performance without correctness regressions:

• bottleneck identification and hypothesis validation
• baseline measurement design
• optimization sequencing and guardrails
• post-change verification and rollback triggers

Required Planning Checks

1. Baseline and targets

• define current baseline metrics
• define explicit success thresholds

2. Bottleneck hypotheses

• list likely bottlenecks and expected impact
• define how each hypothesis will be validated

3. Optimization stages

• sequence changes from low-risk/high-signal to higher-risk
• isolate changes to simplify attribution of gains/regressions

4. Regression guardrails

• define correctness constraints that cannot regress
• define performance rollback triggers and fallback steps

5. Verification

• include benchmark/profile checks per stage
• include acceptance criteria tied to target metrics

Output Adaptation

When contributing to a plan, emphasize:

• measurable goals and thresholds
• instrumentation and benchmark commands
• risk-managed optimization sequencing
• explicit rollback conditions for regressions
