YouTube Skills for AI Agents is a collection of skills that lets AI agents retrieve YouTube transcripts, search videos, inspect channels, and extract playlist contents through an API. It is for agents using runtimes such as OpenClaw, Hermes Agent, Claude Code, and Cursor. The catalogue entries are the project's skills for carrying out these YouTube tasks.
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.

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 | $0.00110 | $0.03219 |
| Opus 5.5 | $0.00044 | $0.01288 |
| Sonnet 5.5 | $0.00022 | $0.00644 |
| Haiku 4.5 | $0.00011 | $0.00322 |
Grade A, and why
transcriptapi 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 28d 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.
Makes network callslowCapability
Not a fault in itself. Listed so you know the mod talks to something, and to what.
curl -s "https://transcriptapi.com/api/v2/youtube/transcript\ How it starts
The opening of the file, as written. The whole thing — 309 lines — stays where its author put it; the contents beside it link to each section on GitHub.
TranscriptAPI
Full YouTube data toolkit via TranscriptAPI.com. Transcripts, search, channels, playlists — one API key.
Setup
If $TRANSCRIPT_API_KEY is not set, read references/auth-setup.md and follow the instructions there to get and store the key.
Required Headers
Every request needs two headers:
- Authorization:
Bearer $TRANSCRIPT_API_KEY - User-Agent: your agent's name and version if known (e.g.
HermesAgent/0.11.0,ClaudeCode/1.0). Version is optional — agent name alone is fine. Do not omit this header or send a bare default — Cloudflare will return a 403 (error code 1010) and block the request.
API Reference
Full OpenAPI spec: transcriptapi.com/openapi.json — consult this for the latest parameters and schemas.
Auth
All requests: -H "Authorization: Bearer $TRANSCRIPT_API_KEY"
Endpoints
Channel endpoints accept channel — an @handle, channel URL, or UC... ID. No need to resolve first. Playlist endpoints accept playlist — a playlist URL or ID.
GET /api/v2/youtube/transcript — 1 credit
curl -s "https://transcriptapi.com/api/v2/youtube/transcript\
?video_url=VIDEO_URL&format=text&include_timestamp=true&send_metadata=true" \
-H "Authorization: Bearer $TRANSCRIPT_API_KEY" \
-H "User-Agent: YourAgent/1.0"
| Param | Required | Default | Validation |

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.

transcriptapi is a skill published in the GitHub repository ZeroPointRepo/youtube-skills (1,093 stars, last pushed 5d ago), licensed MIT. It adds 110 tokens to every session and 3,219 once invoked, about $0.0004 per session on Opus 5.5. 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 2026-08-30.
