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.

A badge with what this costs and how it scanned, read live from this page, so it follows the numbers instead of freezing them. Markdown for a README, HTML for a documentation site or a project page.

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 | $0.00143 | $0.02454 |
| Opus 5 | $0.00072 | $0.01227 |
| Sonnet 5 | $0.00029 | $0.00491 |
| Haiku 4.5 | $0.00014 | $0.00245 |
Grade A, and why
youtube scanned grade A with 0 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 4d 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.
Nothing flagged
None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.
How it starts
The opening of the file, as written. The whole thing — 180 lines — stays where its author put it; the contents beside it link to each section on GitHub.
youtube
The deterministic read path for public YouTube data through UnifAPI. This is a
Data Skill: it does not run a marketing job on its own — it names the
concrete youtube/... operations, response shapes, and the real coverage limits
so any channel- or content-first workflow (creator vetting, competitor
reception, content demand) reads from one known recipe instead of rediscovering
the surface each time.
Read-only — eyes, not hands. It researches public YouTube data and returns cited records; it never uploads, comments, or subscribes, and UnifAPI never holds YouTube credentials.
Use the unifapi skill for live evidence
Connect once through the shared unifapi skill (OAuth MCP), then call the
operations below. Channels are keyed by {channel_id} and videos by
{video_id} — resolve a handle or URL to a channel id first (see Gotchas).
Keep any billing metadata so the output can state record cost.
Response contract
Single-entity endpoints return the object in data:
{
"request_id": "unif_...",
"data": {},
"billing": { "records_charged": 1, "balance_remaining": 99 }
}
List endpoints return an array in data plus pagination:
{
"request_id": "unif_...",
"data": [],
"pagination": { "has_more": false, "next_cursor": null },
"billing": { "records_charged": 1 }
}
When pagination.has_more is true, pass pagination.next_cursor as the next
request's cursor. Always preserve billing when reporting cost.

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.

youtube is a skill published in the GitHub repository unifapi-agent/agents (559 stars, last pushed 2mo ago), licensed MIT. It adds 143 tokens to every session and 2,454 once invoked, about $0.0007 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
