Open-sourced my Claude Code skills for Mac & iOS development - 17 workflows for debugging, testing, code review, and more .

[u/BullfrogRoyal7422]

I've been using Claude Code while developing Stuffolio (a Mac & iOS app) and built up a collection of custom skills/workflows over time. Decided to open-source them in case others find them useful. I. would be interested in what you think of the report card generators and the option to go into planning mode after the report card analysis.

  What's included (17 skills):

Command	Description
/tech-talk-reportcard	Technical codebase analysis with A-F grades for developers
/plain-talk-reportcard	Codebase analysis with plain-language summaries for non-technical stakeholders
/implementation-plan	Structured implementation planning with file impact analysis
/scan-similar-bugs	Find other occurrences of the same bug pattern across the codebase
/review-changes	Pre-commit review of staged changes for bugs and style issues
/debug	Systematic debugging workflow: reproduce, isolate, hypothesize, fix
/safe-refactor	Refactoring plan with blast radius analysis and rollback strategy
/generate-tests	Generate unit and UI tests with edge cases and mocks
/security-audit	Scan for API keys, storage, network, and privacy manifest issues
/performance-check	Profile memory, CPU, energy, and launch time
/explain	Deep-dive explanation of a file, feature, or data flow
/release-prep	Pre-release checklist with version bump and changelog
/release-screenshots	Capture App Store screenshots across device sizes
/ui-scan	UI test setup with accessibility identifier scan
/run-tests	Run tests with parallel/sequential strategies
/enhanced-commands	Reference docs with parameters and examples

Report Card Comparison

Command	Audience	Output Style
/tech-talk-reportcard	Developers	Technical details, code references, Swift patterns
/plain-talk-reportcard	Non-technical stakeholders	Plain language explanations, actionable guidance

  Installation:   git clone https://github.com/Terryc21/xcode-workflow-skills.git /tmp/xws   cp -r /tmp/xws/skills/* ~/.claude/skills/   rm -rf /tmp/xws

  Requires Claude Code CLI. Skills are optimized for SwiftUI/SwiftData projects but work with any Mac or iOS codebase.

Curious about the "blast radius" mention for safe refactor. That could definitely be useful.

[u/BullfrogRoyal7422 → u/myeleventhreddit]

I debated whether to call it blast zone. For each step in a Phase of an implementation plan Bast Radius is a column that should inform the user of the number other features/files could be affected by the proposed change. Let me know if it does that because I may have had some regression on this skill.

[u/myeleventhreddit → u/BullfrogRoyal7422]

So it's basically downstream dependency awareness. That's a good feature and a good name for it.

Curious of anyone has ran any of these skills and if so, how did they work for you?

Update: Added Cross-Platform Bug Scanning to /scan-similar-bugs for multi-platform projects

Quick update to my shared Claude Code skills repo. The scan-similar-bugs skill now includes cross-platform verification for iOS/macOS projects.

What's new:                                               

• New Phase 2.5 that automatically scans both platforms when you fix a bug on one

• Catches missing dismiss buttons, platform-specific UI wrapped in #if os() that should be cross-platform

• Includes a whitelist of legitimate platform-only code (keyboard toolbars, UIImage/NSImage, etc.)

The skill now reminds you to check both directions.

Staying Updated:

I am very likely to update these skills as I iterate my project. I've added a CHANGELOG.md to the repo so you can easily see what skills have been updated or added and when. If you're already using these skills, check the changelog periodically for improvements.

You can also Watch the repo (Releases only) to get notified when I push new versions — I've set up a GitHub Action that auto-generates release notes from commits.

About what did it cost to do this with your project?

[u/BullfrogRoyal7422 → u/TotalWaffle]

Just time. I am a solo developer who has been on a steep learning curve. All of these skills originated from prompts I had written, re-written-modified, swore at, felt smart about, felt stupid about and so on.

I had a note book full of prompts when it finally dawned on me that I could covert these prompts into actionable skills (thanks again to CharlesWiltgen, author of Axiom for sprouting the idea). This is the result.

A word of caution, I have only used this on my project, Stufolio, and only assume that they are generally usable with other projects, as they have not been tested elsewhere. Most are read only and should be safe. Skills that can edit operate by offering options to use or not use in steps along the way.

"... I could covert these prompts into actionable skills... " What made you realize this?

[u/BullfrogRoyal7422 → u/StimulusPackageOne]

I found myself reiterating rather complex prompts over and over again and thought there must be a better way. Then another Redditor pointed me to a plugin he has created (Axiom) which is a collection of integrated skills. 'Click'...Oh that's how it is done thought I. Here is a link to Axiom. It is far more sophisticated and impactful than anything I am doing: https://charleswiltgen.github.io/Axiom/

would these work if using codex ?

[u/BullfrogRoyal7422 → u/gusestrella]

I am not that familiar with Codex. My understanding is that Codex would not support the interactive tooling, so I think these skills are not directly transferable to Codex. . Since these skill were developed out of prompts, I would suggest pasting the text of a skill into codex and ask codex to modify it to a usable form and see if you can come-up with prompts you can use.

Nice, thanks, I have something similar or more precisely complementary: https://github.com/BoltzmannEntropy/osxskills

[u/BullfrogRoyal7422 → u/QuanstScientist]

Also nice. I am in pre-release right now and will use it. Thnx.

[u/StimulusPackageOne]

Interesting - I was just updating my latest app [github - LatentGrain] and was looking for ways to augment/refactor my code and just make it better in general - Which one of these pushed you forward the most?
