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.

What it costs to keep this loaded
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 | $0.00084 | $0.01046 |
| Opus 5 | $0.00042 | $0.00523 |
| Sonnet 5 | $0.00017 | $0.00209 |
| Haiku 4.5 | $0.00008 | $0.00105 |
Grade A, and why
bootstrap-ios 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 9d 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 — 88 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Bootstrap iOS
Use this as the single entry point before touching an Apple-platform app. It is a router skill: discover the project, load only the references needed for the current job, verify that build/test tools exist, then act.
The default posture is conservative:
- Build and test before judging code.
- Prefer modern Swift, SwiftUI, Observation, Swift Concurrency, Swift Testing, SwiftData, and current Xcode APIs.
- Avoid deprecated APIs unless the deployment target requires them.
- Use XcodeBuildMCP or an agent-friendly build script instead of raw,
unfiltered
xcodebuildoutput when possible. - Load focused skill packs on demand. Do not dump every Swift rule into context.
First move
- Detect surfaces: iOS, iPadOS, macOS, mixed web/native, SwiftPM, Xcode project/workspace, Tuist, XcodeGen, CocoaPods, or buildable folders.
- Read references/workflow.md.
- If the task involves setup or machine bootstrap, read references/install-and-bootstrap.md.
- If the task involves building, running, simulator, tests, or debugging, read references/xcodebuildmcp.md.
- Pick only the external skill packs relevant to the current task from references/skill-map.md.

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.

bootstrap-ios is a skill published in the GitHub repository RayFernando1337/rayfernando-skills (129 stars, last pushed 1mo ago), licensed Apache-2.0. It adds 84 tokens to every session and 1,046 once invoked, about $0.0004 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 2026-08-30.
