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 | $0.00068 | $0.01100 |
| Opus 5 | $0.00034 | $0.00550 |
| Sonnet 5 | $0.00014 | $0.00220 |
| Haiku 4.5 | $0.00007 | $0.00110 |
Grade A, and why
scaffolding 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 10d ago.
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.
How it starts
The opening of the file, as written. The whole thing — 123 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Scaffolding
Build the entire app structure in one pass. Every screen, every navigation path, placeholder content everywhere. No detail, no styling, no data. Just the bones.
When to Use
- You just created your Xcode project and dropped in CLAUDE.md + APP_SPEC.md
- You're starting a fresh rebuild of an existing app
- You have your spec and are ready for the first Claude Code session
Prerequisites
- Xcode project created (File > New > App, SwiftUI, SwiftData)
- CLAUDE.md in project root
- APP_SPEC.md in project root
- Git initialized, initial commit made
- Claude Code running in the project directory
The Prompt
One prompt. One session. One output.
Read CLAUDE.md and APP_SPEC.md. Build the full app skeleton.
Every screen from the spec should exist as a SwiftUI view with
placeholder content. Set up the tab navigation (if applicable),
NavigationStacks, and all navigation paths between screens.
No real data. No styling. No custom components. No persistence.
Just the structure so I can tap through every screen in the simulator.
Create the file structure defined in CLAUDE.md. Each view goes
in the correct directory.
What Claude Code Should Produce
File Structure
[AppName]/
├── [AppName]App.swift (entry point with tab view or root navigation)

└── Assets.xcassets/
Each View Should Contain
- A
NavigationStackwrapper (if it's a root tab view) - Placeholder text: "Projects Home" or "Settings will go here"
- Navigation links/sheets wired to their destinations with placeholder triggers
- The correct toolbar items (even if they're just Text placeholders)
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.

scaffolding is a skill published in the GitHub repository troyjthomas/ios-agent-skills (2 stars, last pushed 3mo ago), licensed MIT. It adds 68 tokens to every session and 1,100 once invoked, about $0.0003 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
