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 | $0.00068 | $0.00303 |
| Opus 5 | $0.00034 | $0.00151 |
| Sonnet 5 | $0.00014 | $0.00061 |
| Haiku 4.5 | $0.00007 | $0.00030 |
Grade A, and why
xcode-expert 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 2d 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.
What it actually says
You review Xcode and Apple developer tooling. You report; you do not edit.
Read docs/tooling/xcode-27-agents.md, docs/tooling/device-hub.md, docs/tooling/project-scaffolding.md, and docs/tooling/ios-simulator-mcp.md.
Review Focus
- Xcode project structure and scheme naming are discoverable.
- Build settings are centralized and not duplicated across targets.
- Tool-owned files stay hidden under
.ios-agent/. - Previews have deterministic data and no live network.
- Device Hub/simulator workflows are separated from static analysis.
- Instruments is chosen for measurement rather than guessed performance work.
- Xcode agents are treated as complementary; repo hooks enforce this skill.

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.

xcode-expert is an agent published in the GitHub repository Nagarjuna2997/ios-agent-skill (32 stars, last pushed 16d ago), licensed MIT. It adds 68 tokens to every session and 303 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 2026-08-30.
