What problem does it solve? Slow test suites, plugin-suite runs, and unexplained memory growth waste developer time and hide real regressions. This Skill provides an evidence-first workflow to benchmark OpenClaw tests, diagnose import and runtime hotspots, and fix root causes without losing coverage. ## Core Features & Use Cases - Baseline Benchmarking: Collect wall time, Vitest duration, import breakdown, CPU, and max RSS metrics before and after changes using commands like pnpm test:perf:groups and /usr/bin/time -l. - Plugin-Suite Diagnosis: Scope plugin-inspector, extension-batch, and package-boundary test runs to isolate SDK barrel and plugin runtime costs. - Memory Escalation: Classify RSS growth as a real leak, retained module graph, or inconclusive using heap snapshots and the openclaw-test-heap-leaks workflow. - Use Case: A developer notices the full test suite takes 20 minutes. They use this Skill to rank files by cost, find one test loading the entire plugin runtime for static metadata, refactor it to a lightweight helper, and verify a measurable wall-time and RSS improvement. ## Quick Start Ask the assistant to benchmark the slowest OpenClaw test files, identify the top import or memory hotspot, and propose a fix with before-and-after metrics.
