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 | $0.00120 | $0.03100 |
| Opus 5.5 | $0.00048 | $0.01240 |
| Sonnet 5.5 | $0.00024 | $0.00620 |
| Haiku 4.5 | $0.00012 | $0.00310 |
Grade D, and why
youtube-data-api scanned grade D with 3 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 25d 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.
Asks for rootmediumPrivilege escalation
A mod that escalates privileges can change anything on the machine, not only the project.

curl | sh runs whatever the server returns today, which is not necessarily what it returned when this was reviewed.

Not a fault in itself. Listed so you know the mod talks to something, and to what.
- Bash(curl -s *:*) How it starts
The opening of the file, as written. The whole thing — 321 lines — stays where its author put it; the contents beside it link to each section on GitHub.
YouTube Data API v3
Query and manage YouTube channels, videos, playlists, comments, and search results via the YouTube Data API v3 using curl.
Setup
Getting an API Key (public data only)
- Go to the Google Cloud Console
- Create a new project (or select an existing one)
- Navigate to APIs & Services > Library
- Search for YouTube Data API v3 and click Enable
- Go to APIs & Services > Credentials
- Click Create Credentials > API Key
- (Recommended) Click the key to restrict it: under API restrictions, select Restrict key and choose YouTube Data API v3
An API key is sufficient for reading public data: channel info, public video stats, playlists, search, and comments. It does NOT support mine=true queries or any write operations.
Setting Up OAuth 2.0 (private data and write access)
OAuth is required for:
- Querying your own channel with
mine=true - Uploading videos
- Managing playlists, captions, or channel settings
- Accessing YouTube Analytics or YouTube Reporting APIs
- Rating, commenting, or subscribing on behalf of a user
Create OAuth Credentials
- In Google Cloud Console, go to APIs & Services > Credentials
- Click Create Credentials > OAuth client ID
- If prompted, configure the OAuth consent screen first:
- Choose External (or Internal for Workspace orgs)
- Fill in app name, support email, and developer contact
- Add scopes (see below)
- Add yourself as a test user (required while app is in "Testing" status)
- For client type, choose Desktop app (best for CLI use)
- Download the JSON file — save it as
client_secret.json
OAuth Scopes
| Scope | Access |
|---|---|
youtube.readonly |
Read-only access to account, videos, playlists |
youtube |
Full read/write (manage videos, playlists, etc.) |
youtube.upload |
Upload videos only |
youtube.force-ssl |
Read/write, requires SSL (needed for comments, captions) |
yt-analytics.readonly |
YouTube Analytics read access |
yt-analytics-monetary.readonly |
Analytics including revenue data |
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.

youtube-data-api is a skill published in the GitHub repository trtmn/agent-plugins (2 stars, last pushed 11d ago), licensed Unlicense. It adds 120 tokens to every session and 3,100 once invoked, about $0.0005 per session on Opus 5.5. A static security scan graded it D with 3 findings (asks for root, downloads and executes remote code, makes network calls). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-09-24.
