What it does
The repository collects 16 self-contained skills, each in its own folder with a SKILL.md file and an openai.yaml agent config. They cover recurring engineering tasks: building App Store What's New notes from git history, debugging an iOS app through XcodeBuildMCP, auditing and refactoring SwiftUI, diagnosing SwiftUI and React performance, migrating to Swift Concurrency, packaging and signing SwiftPM macOS apps without Xcode, driving GitHub through the gh CLI, and running multi-agent diff reviews and bug hunts. Several skills run helper shell scripts, and some rely on external tools such as gh, Tuist and XcodeBuildMCP. You install them by copying the folders you need into your agent's skills directory.
Who it is for. For iOS, macOS and frontend developers who work in Codex and other agents that read SKILL.md.
Good fit when
- You need to assemble App Store What's New notes from commit history
- You need to review or refactor SwiftUI code and find performance regressions
- You need a read-only multi-agent diff review or bug investigation
Not a fit when
- The task is unrelated to Apple platforms, frontend or engineering workflows
- Your agent does not pick up SKILL.md folder skills
Example request
Compile the App Store What's New text from commits since the last tagLimitations
Most skills target Apple platforms and expect installed tooling: Xcode, XcodeBuildMCP, Tuist and gh. The set is written mainly for Codex, folders go into $CODEX_HOME/skills, the SKILL.md format is portable but the agent config ships as openai.yaml. The macOS packaging and notarization skills work with developer signing certificates.
How to disable. Remove the skill folders from your agent's skills directory, for example $CODEX_HOME/skills or ~/.claude/skills.
FAQ
Which agents does this work with?
The set is built for Codex, with folders placed in $CODEX_HOME/skills. The SKILL.md format is portable, so other agents that read such folders, for example Claude Code, can pick the skills up too.
Do I have to install all 16 skills?
No. Each skill is self-contained, so copy only the folders you need.

README in short
The README describes a collection of 16 self-contained skills for recurring engineering tasks across Apple platforms, frontend and GitHub work. They include App Store notes, iOS debugging, macOS packaging, SwiftUI and React performance, review and refactoring, and multi-agent diff and bug investigations. Installation comes down to placing the skill folders under $CODEX_HOME/skills. Each skill carries a SKILL.md with triggers, workflow, examples and references. MIT licensed.

--- name: app-store-changelog description: Create user-facing App Store release notes by collecting and summarizing all user-impacting changes since the last git tag (or a specified ref). Use when asked to generate a comprehensive release changelog, App Store "What's New" text, or release notes based on git history or tags. --- # App Store Changelog ## Overview Generate a comprehensive, user-facing changelog from git history since the last tag, then translate commits into clear App Store release notes. ## Workflow ### 1) Collect changes - Run `scripts/collect_release_changes.sh` from the repo root to gather commits and touched files. - If needed, pass a specific tag or ref: `scripts/collect_release_changes.sh v1.2.3 HEAD`. - If no tags exist, the script falls back to full history. ### 2) Triage for user impact - Scan commits and files to identify user-visible changes. - Group changes by theme (New, Improved, Fixed) and deduplicate overlaps. - Drop internal-only work (build scripts, refactors, dependency bumps, CI). ### 3) Draft App Store notes - Write short, benefit-focused bullets for each user-facing change. - Use clear verbs and plain language; avoid internal jargon. - Prefer 5 to 10 bullets unless the user requests a different length.
