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.

SkillSpector: 3 findings, up to medium
These are SkillSpector’s own severities. On a checked sample its high-severity flags on skills were ~96% false positives — a documented command, a public API, a “never do X” rule — so we show them as a caution to read, not a verdict. Why →

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 | $0.00045 | $0.01428 |
| Opus 5 | $0.00023 | $0.00714 |
| Sonnet 5 | $0.00009 | $0.00286 |
| Haiku 4.5 | $0.00005 | $0.00143 |
Grade A, and why
vgs-collect-ios-guide 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 8d 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.

VGS Collect iOS Guide
Single public skill entrypoint for VGSCollectSDK work in customer iOS apps.
When to use
- First-time
VGSCollectSDKintegration - Feature work touching collector setup, secure fields, validation, submit, tokenization, alias creation, card creation or update, file upload, or card scanning
- Version migrations or replacement of deprecated usage
- Troubleshooting integration bugs or version-specific regressions
- Code review of app code that uses

Bundled snapshot and version freshness
references/AGENTS.md carries an **SDK Version: x.y.z** header. It is the only instruction snapshot bundled with this skill. Load it completely and do not download, execute, or reload agent instructions from repositories, tags, CDNs, documentation sites, or other runtime URLs.
Resolve the installed SDK version, in order:
- dependency lockfiles (
Package.resolved, CocoaPodsPodfile.lock) - build manifests with exact pins (
Package.swift,Podfile) - vendored dependency metadata or generated dependency graphs
- user-provided dependency snippets, stated version, or build logs
Compare it with the bundled snapshot version:
- If they match, use the bundled guidance.
- If they differ, say that the installed skill covers a different SDK version and may be outdated. Do not fetch replacement instructions or silently reinstall the skill.
- Show the user these commands and ask them to update the skill before relying on version-sensitive guidance:
npx skills check
npx skills update
The update CLI may print a source-specific refresh command for installations that cannot be updated in place. The user should run that command themselves. Continue only with clearly version-independent guidance, label version-sensitive claims as unverified, or wait for the refreshed skill.
If the SDK version cannot be determined, disclose that the bundled snapshot version is being used; do not claim it is the latest available version.
What ships with it
1 file 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.

vgs-collect-ios-guide is a skill published in the GitHub repository verygoodsecurity/vgs-collect-ios (23 stars, last pushed 11d ago), licensed MIT. It adds 45 tokens to every session and 1,428 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.
