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 5.1 | $0.00070 | $0.05066 |
| Opus 5 | $0.00035 | $0.02533 |
| Sonnet 5 | $0.00014 | $0.01013 |
| Haiku 4.5 | $0.00007 | $0.00507 |
Grade A, and why
virustotal scanned grade A with 1 finding 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.

Not a fault in itself. Listed so you know the mod talks to something, and to what.

The opening of the file, as written. The whole thing — 353 lines — stays where its author put it; the contents beside it link to each section on GitHub.
VirusTotal Scanner
Look up and triage URLs, files, domains, and IPs against VirusTotal's multi-engine aggregation (70+ AV engines, sandboxes, and crowd-sourced threat data).
VirusTotal is evidence, not proof. Aggregated AV verdicts are a signal, not a clean bill of health. Zero detections never means "safe" (see the triage rubric below), and a few detections never means "definitely malware." Always combine VT data with context: file provenance, prevalence, behavior, and the relationships VT exposes.
Privacy & confidentiality — read before submitting anything
Submitting a file or URL (vt scan file, vt scan url, client.scan_file/scan_url) uploads it to VirusTotal, where it becomes available to VirusTotal's premium customers, threat-intel partners, and antivirus vendors. Filenames, document metadata, embedded paths, certificates, and any secrets inside the file/URL (tokens, query-string credentials, internal hostnames) are exposed and effectively permanent and non-retractable.
Hard rules:
- Do NOT upload proprietary source, customer data, signed internal binaries, credentials, private keys, internal/staging URLs, or live incident artifacts without explicit owner approval.
- Hash-first. Before uploading a file, look it up by hash (
vt file <sha256>). A hash lookup discloses nothing about the file's contents — only whether VT has seen that exact hash. Upload only when the hash is unknown and you're authorized to disclose the sample. - URLs leak too. A URL with a session token or PII in the query string discloses those values. Strip secrets, or look up the domain/host reputation instead of submitting the full URL.
- For sensitive samples, use Private Scanning (VT Enterprise / Google Threat Intelligence) — files are analyzed in isolation and not shared with the community or vendors. See the Private Scanning section.
- Public-API licensing limit: the free/public API "must not be used in commercial products or services" or in business workflows that don't contribute new files. Commercial/automated use requires a Premium/Enterprise key.
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.

virustotal is a skill published in the GitHub repository san-npm/skills-ws (2 stars, last pushed 5d ago), licensed MIT. It adds 70 tokens to every session and 5,066 once invoked, about $0.0003 per session on Opus 5. A static security scan graded it A with 1 finding (makes network calls). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-09-07.
