Is the Xcode Makefiles skill free?

Yes. The skill itself is free from robertguss/claude-code-toolkit. SkillProof publishes the install command and an independent test verdict at no cost.

Does Xcode Makefiles work with Claude Code?

We tested it with Claude Code 2.x (agent harness) on Jul 13, 2026. Verdict: Works with setup. Actually ran the bundled install.sh --dry-run and a real install against a fake Xcode project: it correctly writes a Makefile with build/DerivedData/ , build/logs/ etc. exactly as documented, but the real (non-dry-run) install always exits 1 with an AppleScript syntax error from a broken move_to_trash.sh quoting bug — the files ARE copied correctly, but it looks like a failed install and needs a manual `echo $?`-style sanity check.

What is the Xcode Makefiles SkillProof Score?

8.8/10 — installs cleanly 4/5, triggers reliably 5/5, output vs. baseline 9/10, docs & honesty 4/5.

How do I install Xcode Makefiles?

Copy the install command from this page, run it in your terminal, and restart Claude Code. Skills live in ~/.claude/skills/ (global) or .claude/skills/ inside a project.

Can I use Xcode Makefiles with Cursor, Copilot, Gemini CLI, Codex or other AI tools?

The SKILL.md format is native to Claude (Claude Code, Desktop, claude.ai). The instructions inside adapt to other assistants: Cursor rules, GitHub Copilot instructions, Windsurf rules, Custom GPTs, AGENTS.md for OpenAI Codex, and GEMINI.md for Google Gemini CLI — our conversion guides cover each, and the free converter on the tools page does the wrapping for you.

What Xcode Makefiles does

Installs a Makefile plus xcbuild/diagnose/run/clean scripts into an iOS or macOS project so builds, tests, and runs work from the CLI without opening Xcode, isolating DerivedData/logs/cache/tmp per AGENT_NAME so multiple coding agents can build the same project in parallel without clobbering each other. Trigger it when a project needs reproducible local CLI builds or when parallel agents are stepping on each other's build artifacts.

How to install Xcode Makefiles

git clone https://github.com/robertguss/claude-code-toolkit
cd claude-code-toolkit
mkdir -p ~/.claude/skills
cp -r skills/mobile-app-dev/ios-mac-app-creator/xcode-makefiles ~/.claude/skills/xcode-makefiles

Skills live in ~/.claude/skills/ (global) or .claude/skills/ (per-project). Restart Claude Code after installing.

Commands — how to trigger Xcode Makefiles

/xcode-makefiles Installs an AGENT_NAME-isolated Makefile + script toolkit for CLI-only Xcode builds.

It also activates on plain-language prompts like these:

Set up a Makefile so I can build my iOS app from the CLI
Let multiple coding agents build this Xcode project in parallel
Install CLI build scripts so I don't need to open Xcode
