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 | $0.00111 | $0.04177 |
| Opus 5 | $0.00056 | $0.02089 |
| Sonnet 5 | $0.00022 | $0.00835 |
| Haiku 4.5 | $0.00011 | $0.00418 |
Grade A, and why
audit-xcode-security-settings 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 5d 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 — 217 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Audit Xcode Security Settings
Assess an Xcode project's security posture and progressively enable security build settings and entitlements — from broadly applicable warnings through Enhanced Security hardening.
Tool Preferences
When GetTargetBuildSettings writes its output to a saved file due to a token limit, see references/reading-build-settings.md for the schema and the filter script (scripts/filter_build_settings.py). Do not read the saved file linearly.
When XcodeGlob, XcodeGrep, XcodeRead, and XcodeLS tools are available, ALWAYS use them. Do not fall back to Bash filesystem tools (ls, find, cat, grep) to learn about the project. They trigger extra permission prompts and bypass project scoping.
- XcodeGlob for file discovery —
findis forbidden for files inside the project. - XcodeGrep for content search —
grep/rgis forbidden for files inside the project. - XcodeRead for file contents —
cat/Readis forbidden for files registered in the project. - XcodeLS for directory listing —
lsis forbidden for any path inside the project.
Project root and name are already in the system prompt context. Do NOT run ls to "verify" the project layout before starting. The system prompt already tells you the working directory and the project structure.
Empty XcodeGlob results are not a failure. The .xcodeproj and .xcworkspace are not indexed as files inside the Xcode project organization — XcodeGlob "**/*.xcodeproj" correctly returns 0 matches. Use the project name from system-prompt context instead. Do not fall back to filesystem ls/find.
Path translation between project-org and filesystem. XcodeGlob returns project-org-relative paths. To read or edit a file:
- Prefer
XcodeRead/XcodeUpdatewith the project-org path. - If that path is rejected (some on-disk files like
.entitlementsplists may not be navigable throughXcodeRead), translate to a filesystem absolute path by prepending the project root from system context. Do NOT usefindto discover the on-disk path.
What ships with it
15 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.

audit-xcode-security-settings is a skill published in the GitHub repository aduermael/herm (232 stars, last pushed 23d ago), licensed MIT. It adds 111 tokens to every session and 4,177 once invoked, about $0.0006 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.
