Claude Code performance-check for measured startup targets
Review measured rendering, memory, database, startup, and network performance against the app’s targets and prioritize the gaps.
中文Install in Claude Code
Open the runnable app in Claude Code with its performance targets and measurements recorded under matched device and data conditions.
- Review `.claude/skills/performance/SKILL.md` and its requirements at the pinned GitHub commit.
- Create `.claude/skills/performance/` in your project and save the reviewed file as `.claude/skills/performance/SKILL.md`.
- Start Claude Code from that project's root, then select `/performance-check` in the slash menu or type the directory command `/performance`.
Example task
In perf-16, the project targets cold start under 3 seconds. The baseline is 4.2 seconds, and data loads before first paint.What to check
Record {targetSeconds: 3, measuredSeconds: 4.2, meetsTarget: false}. Defer data loading not needed for initial paint and measure again under the same conditions.
