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 | $0.00182 | $0.02220 |
| Opus 5.5 | $0.00073 | $0.00888 |
| Sonnet 5.5 | $0.00036 | $0.00444 |
| Haiku 4.5 | $0.00018 | $0.00222 |
Grade A, and why
youtube-cli 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 today.
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.

<quick_start>
The youtube CLI follows this pattern:
youtube <group> <action> [args] [options]
| Task | Command |
|---|---|
| Download video | youtube videos download "URL" |
| Download channel videos | youtube videos download --channel channelname |
| Download transcript | youtube transcripts download "URL" |
| Download as text | youtube transcripts download "URL" --format txt |
| Download to folder | youtube videos download "URL" -o ~/videos/ |
| Multiple videos | youtube videos download "URL1" "URL2" |
| OAuth login (one-time) | youtube auth login (prompts for Client ID/Secret, opens browser) |
| List my channel videos | youtube channel videos list -t |
| Get my video metadata | youtube channel videos get VIDEO_ID |
| Validate video chapters | youtube videos chapters validate --description $'00:00 Intro\n00:12 Setup\n02:05 Demo' |
| Upload a video | youtube channel videos upload PATH --title "T" --privacy private |
| Ask AI to add chapters before upload | youtube channel videos upload PATH --title "T" --description "D" --include-recommended-chapters |
| Upload a Short | youtube shorts upload PATH --title "T" --privacy public --profile P (then add captions with the next row) |
| Add captions to an owned video (the only caption path; upload has no caption flags) | youtube channel videos captions add VIDEO_ID C.srt --language en --profile P |
| Schedule a video | youtube channel videos upload PATH --title "T" --privacy private --publish-at 2026-06-01T15:00:00Z |
| Update a video | youtube channel videos update VIDEO_ID --title "New" --privacy public |
| Delete a video | youtube channel videos delete VIDEO_ID --yes |
| Post a channel message | youtube channel posts create --message "Text" --profile brickbuddy |
| List ALL my channels (every profile) | youtube channels list -t |
| List one profile's channel | youtube channels list --profile brickbuddy |

MANDATORY: Consult the adjacent usage.json at <cli-tools-root>/_repo/skills/<tool>-cli/usage.json before executing ANY youtube command.
This file contains complete command syntax, all arguments, all options, and usage instructions for every command. Never guess at command syntax.
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.
