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: 5 findings, up to high
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 →

- medium Rogue Agent · line 49 Skill establishes unauthorized persistence across sessions via cron jobs, startup scripts, or state files. Session persistence allows an attacker to maintain access beyond the current interaction.Fix: Remove any persistence mechanisms (cron jobs, startup scripts, state files). Skills should not maintain state across sessions without explicit user consent.
- medium Data Exfiltration · line 83 Data is being sent to an external URL. This could be legitimate telemetry or data exfiltration. Manual review is recommended.Fix: Verify the destination URL is trusted and necessary. Remove or replace with documented APIs. Ensure no secrets, tokens, or PII are transmitted.
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 | $0.00046 | $0.01849 |
| Opus 5 | $0.00023 | $0.00924 |
| Sonnet 5 | $0.00009 | $0.00370 |
| Haiku 4.5 | $0.00005 | $0.00185 |
Grade B, and why
zoom scanned grade B with 2 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 6d 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.

Zoom Skill
Manage Zoom meetings and cloud recordings via the Zoom API.
Features
- Meetings: List, create, update, delete scheduled meetings
- Recordings: List cloud recordings with transcripts, summaries, and download links
Note: All times passed to create/update commands are interpreted as local time. The script auto-detects your timezone if not explicitly specified with --timezone.
Prerequisites
This skill uses two authentication methods:
| Feature | Auth Type | Credentials File |
|---|---|---|
| Meetings | Server-to-Server OAuth | ~/.zoom_credentials/credentials.json |
| Recordings | User OAuth (General App) | ~/.zoom_credentials/oauth_token.json |
Check status:
python3 scripts/zoom_meetings.py setup
Setup
Part 1: Server-to-Server OAuth (for Meetings)
- Go to marketplace.zoom.us → Develop → Build App
- Select Server-to-Server OAuth
- Name it (e.g., "Claude Zoom Meetings")
- Copy Account ID, Client ID, Client Secret
- Add scopes:
meeting:read:meeting:adminmeeting:read:list_meetings:adminmeeting:write:meeting:adminuser:read:user:admin
- Activate the app
- Save credentials:
mkdir -p ~/.zoom_credentials
cat > ~/.zoom_credentials/credentials.json << 'EOF'
{
"account_id": "YOUR_ACCOUNT_ID",
"client_id": "YOUR_CLIENT_ID",
"client_secret": "YOUR_CLIENT_SECRET"
}
EOF
Part 2: General App OAuth (for Recordings)
Server-to-Server apps cannot access cloud recordings. You need a separate General App:
- Go to marketplace.zoom.us → Develop → Build App
- Select General App
- Set redirect URL:
http://localhost:8888/callback - Copy Client ID and Client Secret
- Add scopes:
cloud_recording:read:list_user_recordingscloud_recording:read:list_recording_files
- Activate the app
- Authorize (one-time browser flow):
# Open this URL in browser (replace CLIENT_ID):
https://zoom.us/oauth/authorize?response_type=code&client_id=YOUR_CLIENT_ID&redirect_uri=http://localhost:8888/callback
# After authorizing, you'll be redirected to:
# http://localhost:8888/callback?code=AUTHORIZATION_CODE
# Exchange the code for tokens (replace values):
python3 -c "
import requests, json
resp = requests.post('https://zoom.us/oauth/token',
auth=('CLIENT_ID', 'CLIENT_SECRET'),
data={'grant_type': 'authorization_code', 'code': 'AUTH_CODE', 'redirect_uri': 'http://localhost:8888/callback'})
data = resp.json()
data['client_id'] = 'CLIENT_ID'
data['client_secret'] = 'CLIENT_SECRET'
data['expires_at'] = __import__('time').time() + data.get('expires_in', 3600)
with open(__import__('pathlib').Path.home() / '.zoom_credentials/oauth_token.json', 'w') as f:
json.dump(data, f, indent=2)
print('Saved!')

What ships with it
3 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.
- 6d ago First seen · 222 lines · 46 tokens per session scan B 1df7621e5f3c
zoom is a skill published in the GitHub repository glebis/claude-skills (374 stars, last pushed 7d ago), licensed MIT. It adds 46 tokens to every session and 1,849 once invoked, about $0.0002 per session on Opus 5. A static security scan graded it B with 2 findings (sends data to an external url, makes network calls). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-09-03.
