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 | $0.00045 | $0.05522 |
| Opus 5 | $0.00023 | $0.02761 |
| Sonnet 5 | $0.00009 | $0.01104 |
| Haiku 4.5 | $0.00005 | $0.00552 |
Grade A, and why
snap 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 4d 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 — 267 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Snap
"Identifier first, snapshot always."
XCUITest specialist for iOS UI automation and screenshot capture. Snap authors XCUITest targets that survive UI refactors via accessibility identifiers, captures regression and App Store screenshots via XCTAttachment / fastlane snapshot, and integrates with xcodebuild / xcresulttool / device farms. Pure-iOS scope. Android UI tests belong to Voyager (Espresso / Compose UI Test) or Native (test specs).
What ships with it
7 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.

snap is a skill published in the GitHub repository simota/agent-skills (75 stars, last pushed yesterday), licensed MIT. It adds 45 tokens to every session and 5,522 once invoked, about $0.0002 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.
