app-creator

A guided setup tool for creating new iOS or macOS apps, or adding selected development helpers to an existing project. It can generate projects with XcodeGen, a tool that creates Xcode project files from configuration.

In plain words
What is it for?
Use it to scaffold an iOS or macOS app with SwiftUI, UIKit, or AppKit, or to add the xcode-makefiles and simple-tasks helpers to an existing project. It can also run checks and show the next commands.
Why use it?
It avoids repeating project setup by hand and provides a defined path for either starting a project or adopting the workflow without regenerating an existing one.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

app-creator scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 2d ago.

The scan reads SKILL.md. This mod also ships 8 executable files (scripts/doctor.sh, scripts/init.sh, scripts/install_agents.sh, …), listed below but not scanned — reading those needs a real analyzer, not pattern matching.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

What it actually says

App Creator

Overview

Paul Solt [email protected] Version: 0.9.8

app-creator is now an orchestrator skill.

Responsibilities:

  1. Scaffold new projects with XcodeGen templates.
  2. Adopt existing projects non-destructively.
  3. Optionally install subskills:
    • xcode-makefiles
    • simple-tasks

Workflow

  1. Collect inputs.
  2. Run doctor checks.
  3. Choose mode: new or adopt.
  4. In new mode, scaffold app templates and run XcodeGen.
  5. Install selected subskills (default: both).
  6. Optionally initialize git and create a baseline commit.
  7. Print exact next commands.

Modes

New Project

Run:

skills/app-creator/scripts/init.sh --project-mode new

Required fields in new mode:

  • App name
  • Bundle id
  • Platform (ios or macos)
  • UI framework (swiftui, uikit, appkit)
  • Output directory

Adopt Existing Project

Run:

skills/app-creator/scripts/init.sh --project-mode adopt

Behavior:

  • No scaffolding/regeneration.
  • Only installs selected subskills into the existing project.

Subskill install defaults

Wizard defaults to installing both:

  • xcode-makefiles
  • simple-tasks

You can opt out with:

  • --skip-xcode-makefiles
  • --skip-simple-tasks

Dry run

Use --dry-run to preview actions without mutating files.

Git onboarding

init.sh/scaffold_app.sh support:

  • --git-init auto|never
  • --git-commit prompt|always|never

Defaults:

  • --git-init auto
  • --git-commit prompt

Safety behavior:

  • If the target repo is already dirty before app-creator runs, auto-commit is skipped.
  • If there are no staged/unstaged changes after install/scaffold, no commit is created.

Resources

Use these files when you need details beyond the workflow:

  • references/workflow.md
  • references/placeholders.md
Files

What ships with it

46 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.

Changes

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
