Identifies performance bottlenecks and provides ordered scaling strategies with triggers, phased plans, and cost implications. Use for "scalability planning", "performance bottlenecks", "capacity planning", or "growth strategy".
Autonomously optimize code for performance using CodSpeed benchmarks, flamegraph analysis, and iterative improvement. Use this skill whenever the user wants to make code faster, reduce CPU usage, optimize memory, improve throughput, find performance bottlenecks, or asks to 'optimize', 'speed up', 'make faster', 'reduce latency', 'improve performance', or points at a CodSpeed benchmark result wanting improvements. Also trigger when the user mentions a slow function, a regression, or wants to understand where time is spent in their code.
Flamegraph generation and interpretation skill. Use when converting perf, Valgrind Callgrind, or other profiler output into SVG flamegraphs using Brendan Gregg's FlameGraph tools, or when reading flamegraphs to identify performance bottlenecks. Activates on queries about flamegraphs, stackcollapse, flamegraph.svg, identifying hot frames, wide vs tall frames, or performance visualisation.
Analyzes code for performance and scalability issues, producing fitness scores (1-10) across algorithmic efficiency, database design, caching strategy, scalability readiness, resource utilization, and data pipeline efficiency. Covers services, CLIs, CI scripts, batch jobs, and ML inference code. Use when the user says /review:performance, requests a performance review, asks for scalability analysis, wants to find N+1 queries or Big-O hot paths, asks why something gets slow as data grows, or needs performance fitness scores before shipping. Only reports findings with confidence >= 7/10.
