Add this skill
Claude
This repository is a Claude Code plugin marketplace. In Claude Code:
/plugin marketplace add AvdLee/Xcode-Build-Optimization-Agent-Skill
/plugin install xcode-build-skills@xcode-build-skillsIn the Claude apps, zip the xcode-compilation-analyzer folder and upload it under Customize > Skills > + > Upload a skill (code execution must be on).
ChatGPT / Codex
Codex reads skills from .agents/skills/ in a repo or ~/.agents/skills/ for every project:
git clone --depth 1 https://github.com/AvdLee/Xcode-Build-Optimization-Agent-Skill.git
cp -r Xcode-Build-Optimization-Agent-Skill/skills/xcode-compilation-analyzer .agents/skills/xcode-compilation-analyzer # repo; ~/.agents/skills for all projectsStandalone skills also load in the ChatGPT desktop app.
Cursor
Cursor loads skills from .cursor/skills/ (or ~/.cursor/skills/) and also reads .claude/skills/:
git clone --depth 1 https://github.com/AvdLee/Xcode-Build-Optimization-Agent-Skill.git
cp -r Xcode-Build-Optimization-Agent-Skill/skills/xcode-compilation-analyzer .cursor/skills/xcode-compilation-analyzer # project; ~/.cursor/skills for all projectsSource (checked Oct 7, 2026): code.claude.com/docs/en/skills (opens in a new tab), code.claude.com/docs/en/plugin-marketplaces (opens in a new tab), support.claude.com/en/articles/12512180-using-skills-in-claude (opens in a new tab), learn.chatgpt.com/docs/build-skills (opens in a new tab), cursor.com/docs/context/skills (opens in a new tab)
What this skill does
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. Use this skill when compile time, not just general project configuration, looks like the bottleneck.
When it triggers
- 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.
