Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00162 | $0.03374 |
| Opus 5.5 | $0.00065 | $0.01350 |
| Sonnet 5.5 | $0.00032 | $0.00675 |
| Haiku 4.5 | $0.00016 | $0.00337 |
Grade C, and why
developing-ios-apps scanned grade C with 1 finding 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 yesterday.
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.
Recursive force deletehighDestructive command
rm -rf with a variable or a broad path is one typo away from removing the wrong tree.
| Clean DerivedData | `rm -rf ~/Library/Developer/Xcode/DerivedData/PROJECT-*` | This is a copy
92% identical to developing-ios-apps — 7 lines differ, which has more behind it and is treated as the original. This page carries a canonical link to it rather than competing with it.
How it starts
The opening of the file, as written. The whole thing — 373 lines — stays where its author put it; the contents beside it link to each section on GitHub.
iOS App Development
Build, configure, and deploy iOS applications using XcodeGen and Swift Package Manager.
Critical Warnings
| Issue | Cause | Solution |
|---|---|---|
| "Library not loaded: @rpath/Framework" | XcodeGen doesn't auto-embed SPM dynamic frameworks | Build in Xcode GUI first (not xcodebuild). See Troubleshooting |
xcodegen generate loses signing |
Overwrites project settings | Configure in project.yml target settings, not global |
| Command-line signing fails | Free Apple ID limitation | Use Xcode GUI or paid developer account ($99/yr) |
| "Cannot be set when automaticallyAdjustsVideoMirroring is YES" | Setting isVideoMirrored without disabling automatic |
Set automaticallyAdjustsVideoMirroring = false first. See Camera |
| App signed as adhoc despite certificate | @electron/packager defaults continueOnError: true |
Set continueOnError: false in osxSign. See Code Signing |
| "Cannot use password credentials, API key credentials..." | Passing teamId to @electron/notarize with API key auth |
Remove teamId. notarytool infers team from API key. See Code Signing |
| EMFILE during signing (large embedded runtime) | @electron/osx-sign traverses all files in .app bundle |
Add ignore filter + ulimit -n 65536 in CI. See Code Signing |

What ships with it
6 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.
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.

developing-ios-apps is a skill published in the GitHub repository The-Artificer-of-Ciphers-LLC/skills-from-the-artificer (6 stars, last pushed 2d ago), licensed MIT. It adds 162 tokens to every session and 3,374 once invoked, about $0.0006 per session on Opus 5.5. A static security scan graded it C with 1 finding (recursive force delete). It is 92% identical to developing-ios-apps, differing in 7 lines, and is treated as a copy.
