I build Stuffolio, a Universal iOS/iPadOS/macOS app, under Coffee & Code LLC. The open-source Claude Code skills below have come out of shipping it — each solving a real problem I hit taking a 600-file Swift app through App Store review. Free and open source.

🛠️ Claude Code Skills

Each skill is its own repo — install just the ones you want.

🔍 Find the bugs linters can't

Pattern-based linters (SwiftLint and friends) check each file against a rule catalog. These skills are behavioral — they read *across* files to catch bugs that live in the handoffs, where every individual file is locally correct but the loop silently breaks.

| Skill | What it does |
|-------|--------------|
| radar-suite v2.1.1 ⭐17 | Six audit skills for iOS/Swift apps: SwiftData/Core Data models, navigation reachability, backup/restore round-trips, time-bomb code that breaks on aged data, and visual quality — plus a capstone that grades the codebase ship/no-ship. Every finding cites a real file:line. |
| workflow-audit v3.0.0 ⭐52 | Traces what a user *trying to accomplish a task* actually experiences, screen by screen — catching dead ends, dismiss traps, and broken flows that no single-file check can see. |
| bug-prospector v1.0.0 ⭐2 | Hunts for hidden bugs that pattern matchers miss: logic errors, broken assumptions, unhandled state transitions, and places where code quietly drifts from its intent. |
| bug-echo v1.1.1 | After you fix a bug, finds and rates *other instances of the same pattern* — because the one you just fixed is rarely the only one. |

⚡ Work better with Claude Code

| Skill | What it does |
|-------|--------------|
| prompter v1.0.0 | Rewrites your prompt for clarity, typos, and actionability — but only when it would actually help, and it shows you the rewrite first. Preserves your voice; holds back on prompts that are already clear. |
| unforget v0.2.0 ⭐5 | A single source of truth for deferred work, in one UNFORGET.md per project. Solves the failure mode where punted work gets logged in five places and then nobody can find it at release time. |
| skill-reviewer v0.3.0 ⭐23 | Candid, structured reviews of Claude Code skills before you publish — discoverability, safety, architecture, parseability — with file:line citations instead of vague praise. |
| tutorial-creator v2.0.0 ⭐22 | Generates annotated code-reading tutorials from *your own* codebase, tracks the concepts you've learned, and turns them into shareable teaching artifacts. |

📦 Install

Each skill installs independently. Add its marketplace, then install:

bash
# Example: radar-suite
/plugin marketplace add Terryc21/radar-suite
/plugin install radar-suite

Swap radar-suite for any skill above (workflow-audit, prompter, unforget, etc.). Several are also under review for the official community marketplace — once approved, they'll install as @claude-community.

☕ About

If a skill catches a real bug or saves you a release, a coffee is appreciated — but an issue report about what worked or didn't is worth more.
