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 | $0.00023 | $0.00534 |
| Opus 5 | $0.00012 | $0.00267 |
| Sonnet 5 | $0.00005 | $0.00107 |
| Haiku 4.5 | $0.00002 | $0.00053 |
Grade A, and why
js-youtube-ops-skill 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 11d 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.

Recording
js-youtube-ops-skill 现已接入统一的 skill recording 底座，支持调用历史、结果缓存和调试记录。
- 默认记录模式跟随
js-eyes全局配置中的recording.mode - CLI 可覆盖：
--recording-mode off|history|standard|debug--debug-recording--no-cache--recording-base-dir /absolute/path--run-id custom-id
该技能的 debug 语义以子进程链路为主，重点记录：
yt-dlp调用命令与参数摘要- 每次尝试的 exit code
- stderr 摘要与 cookie fallback 情况
默认按技能分目录落盘到 ~/.js-eyes/skill-records/js-youtube-ops-skill/。

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.

js-youtube-ops-skill is a skill published in the GitHub repository imjszhang/js-eyes (43 stars, last pushed 2d ago), licensed MIT. It adds 23 tokens to every session and 534 once invoked, about $0.0001 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.
