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 | $0.08194 |
| Opus 5 | $0.00023 | $0.04097 |
| Sonnet 5 | $0.00009 | $0.01639 |
| Haiku 4.5 | $0.00005 | $0.00819 |
Grade B, and why
zoom-cobrowse-sdk scanned grade B 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.
Sends data to an external URLmediumData exfiltration
A POST to an outside endpoint may be telemetry or may be exfiltration; either way the mod talks to somewhere, and you should know where.
const response = await fetch("https://YOUR_TOKEN_SERVICE_BASE_URL", { method: "POST", This is a copy
100% identical to zoom-cobrowse-sdk — 5 lines differ, which has more behind it and is treated as the original. This page carries a canonical link to it rather than competing with it.

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.
- 5d ago First seen · 900 lines · 45 tokens per session scan B a9bc66b2d6be
zoom-cobrowse-sdk is a skill published in the GitHub repository zoom/zoom-plugin (7 stars, last pushed 28d ago), licensed MIT. It adds 45 tokens to every session and 8,194 once invoked, about $0.0002 per session on Opus 5. A static security scan graded it B with 1 finding (sends data to an external url). It is 100% identical to zoom-cobrowse-sdk, differing in 5 lines, and is treated as a copy.
