Compares two Gradle build runs to identify duration regressions, cache changes, and task outcome differences. Can be invoked with build IDs, dashboard URLs, or branch names.
Audit Xcode project configuration, build settings, scheme behavior, and script phases to find build-time improvements with explicit approval gates. Use when a developer wants project-level build analysis, slow incremental builds, guidance on target dependencies, build settings review, run script phase analysis, parallelization improvements, or module-map and DEFINES_MODULE configuration.
Webpack build optimization expert with deep knowledge of configuration patterns, bundle analysis, code splitting, module federation, performance optimization, and plugin/loader ecosystem. Use PROACTIVELY for any Webpack bundling issues including complex optimizations, build performance, custom plugins/loaders, and modern architecture patterns. If a specialized expert is a better fit, I will recommend switching and stop.
Vite-specific bundle optimization patterns. Use when configuring builds, code splitting, managing dependencies, or troubleshooting slow Vite builds.
Use when build times are slow, investigating build performance, analyzing Build Timeline, identifying type checking bottlenecks, enabling compilation caching, or optimizing incremental builds - comprehensive build optimization workflows including Xcode 26 compilation caching
Use this skill to measure performance baselines, detect regressions before/after PRs, and compare stack alternatives.
Analyzes and optimizes Dockerfiles to reduce image size, improve build time, and enhance security. Use when optimizing Docker images, reducing build times, or improving Dockerfile structure.
Benchmark Xcode clean and incremental builds with repeatable inputs, timing summaries, and timestamped `.build-benchmark/` artifacts. Use when a developer wants a baseline, wants to compare before and after changes, asks to measure build performance, mentions build times, build duration, how long builds take, or wants to know if builds got faster or slower.
Optimize Bazel builds for large-scale monorepos. Use when configuring Bazel, implementing remote execution, or optimizing build performance for enterprise codebases.
Establish build performance baselines and apply systematic optimization techniques. Only activate in MSBuild/.NET build context. Use when diagnosing slow builds, establishing before/after measurements, or applying advanced optimization strategies like MSBuild Server, static graph builds, artifacts output, and dependency graph trimming. Start here before diving into specific optimizations from build-perf-diagnostics, incremental-build, or build-parallelism skills. DO NOT use for non-MSBuild build systems.
Use when ANY iOS build fails, test crashes, Xcode misbehaves, or environment issue occurs before debugging code. Covers build failures, compilation errors, dependency conflicts, simulator problems, environment-first diagnostics.
