Install

Skills CLI

npx skills add AvdLee/Xcode-Build-Optimization-Agent-Skill

Asks which skills and agents to install. Just one: npx skills add AvdLee/Xcode-Build-Optimization-Agent-Skill --skill spm-build-analysis — add -g for every project.

Claude Code

git clone https://github.com/AvdLee/Xcode-Build-Optimization-Agent-Skillcp -r "Xcode-Build-Optimization-Agent-Skill/skills/spm-build-analysis" ~/.claude/skills/

Copies the spm-build-analysis skill into ~/.claude/skills/ for every project (use .claude/skills/ for one project). Repeat for the other skills listed below.

Plugin

/plugin marketplace add AvdLee/Xcode-Build-Optimization-Agent-Skill

Run inside Claude Code if the repository ships a plugin marketplace, then pick plugins from /plugin.

Skills can run code on your machine — read the SKILL.md first.

What it does

In the author's own words, from each skill's SKILL.md.

  • spm-build-analysis

    Analyze Swift Package Manager dependencies, package plugins, module variants, and CI-oriented build overhead that slow Xcode builds. Use when a developer suspects packages, plugins, or dependency graph shape are hurting clean or incremental build performance, mentions SPM slowness, package resolution time, build plugin overhead, duplicate module builds from configuration drift, circular dependenc…

  • xcode-build-benchmark

    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.

    skills/xcode-build-benchmark/SKILL.md on GitHub (opens in a new tab)

  • xcode-build-fixer

    Apply approved Xcode build optimization changes following best practices, then re-benchmark to verify improvement. Use when a developer has an approved optimization plan from xcode-build-orchestrator, wants to apply specific build fixes, needs help implementing build setting changes, script phase guards, source-level compilation fixes, or SPM restructuring that was recommended by an analysis skil…

    skills/xcode-build-fixer/SKILL.md on GitHub (opens in a new tab)

  • xcode-build-orchestrator

    Orchestrate Xcode build optimization by benchmarking first, running the specialist analysis skills, prioritizing findings, requesting explicit approval, delegating approved fixes to xcode-build-fixer, and re-benchmarking after changes. Use when a developer wants an end-to-end build optimization workflow, asks to speed up Xcode builds, wants a full build audit, or needs a recommend-first optimizat…

  • xcode-compilation-analyzer

    Analyze Swift and mixed-language compile hotspots using build timing summaries and Swift frontend diagnostics, then produce a recommend-first source-level optimization plan. Use when a developer reports slow compilation, type-checking warnings, expensive clean-build compile phases, long CompileSwiftSources tasks, warn-long-function-bodies output, or wants to speed up Swift type checking.

    skills/xcode-compilation-analyzer/SKILL.md on GitHub (opens in a new tab)

  • xcode-project-analyzer

    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.

Review before you install

A skill is a set of instructions and scripts your agent will follow, and it can run code on your machine. Read the SKILL.md and any scripts first — this listing is not a security review.
