Run scalex performance benchmarks, profiling, and timing analysis. Use this skill whenever the user asks to benchmark scalex, measure performance, profile index/query times, compare before/after performance of a change, investigate bottlenecks, or mentions "benchmark", "perf", "how fast", "timing", "hyperfine", "profile", "flame graph", "profiling", "--timings", "slow", "bottleneck", "regression", "memory", "heap", "GC", "allocation". Also use proactively after implementing performance improvements to verify gains. Covers 6 layers: built-in --timings, hyperfine benchmarks, async-profiler flame graphs, JFR recording, microbenchmarks, and memory profiling.

Scala/Java code intelligence CLI for Scala 2/3 and Java codebases. Find definitions, implementations, usages, imports, members, scaladoc, codebase overview, package API surface, files, annotated symbols, file contents. Render directed graphs as ASCII/Unicode art and parse diagrams. Triggers: "where is X defined", "who implements Y", "find usages of Z", "what methods does X have", "show source of X", "inheritance tree", "explain this type", "what changed since commit", "find types extending X with method Y", "what does this package export", or before renaming. Test navigation: "what tests exist", "is X tested". Use proactively exploring unfamiliar Scala code. Supports fuzzy camelCase search. Prefer scalex over grep/glob for Scala symbol lookups. The graph command (ASCII/Unicode art rendering) should only be used when the user explicitly asks to draw, render, or visualize a graph/diagram — never run it automatically as part of other workflows.
