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.

SkillSpector: 5 findings, up to high
These are SkillSpector’s own severities. On a checked sample its high-severity flags on skills were ~96% false positives — a documented command, a public API, a “never do X” rule — so we show them as a caution to read, not a verdict. Why →

- medium Rogue Agent · line 20 Skill establishes unauthorized persistence across sessions via cron jobs, startup scripts, or state files. Session persistence allows an attacker to maintain access beyond the current interaction.Fix: Remove any persistence mechanisms (cron jobs, startup scripts, state files). Skills should not maintain state across sessions without explicit user consent.
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 | $0.00081 | $0.01725 |
| Opus 5 | $0.00041 | $0.00863 |
| Sonnet 5 | $0.00016 | $0.00345 |
| Haiku 4.5 | $0.00008 | $0.00172 |
Grade A, and why
video-audio-add 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 12d 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.

Video Audio Add
Overview
为已有视频添加音频轨道，覆盖 2 类场景并可串联：
- 添加背景音乐（BGM）：工具内部根据
prompt描述检索素材库匹配音乐，或使用自定义audio_url；video_volume默认1（不压低原声）。 - 添加旁白配音：工具内部根据
prompt中音色描述检索音色素材；video_volume默认0（压低原声突出旁白）。
BGM + 旁白需同时添加时，串联执行 video_bgm_add → video_narration_add。
不处理：视频拼接、拼接+配乐一体化、纯音乐/歌曲生成、视频内容/画面编辑。

触发信号与路由
| 用户原话 | 路由 |
|---|---|
加 BGM / 配个背景音乐 / 换背景音乐（无 audio_url） |
video_bgm_add（内部根据 prompt 检索素材） |
"用这段音频做配乐"（有 audio_url） |
video_bgm_add（跳过内部检索，直接用 audio_url） |
| 加旁白 / 加配音 / 配解说 / 加画外音 | video_narration_add，prompt 含旁白文案 + 音色偏好 |
| 配音配乐 / 加 BGM 和旁白 | 串联：先 video_bgm_add → 再 video_narration_add |

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.
- 12d ago First seen · 147 lines · 81 tokens per session scan A def98951cc9f
video-audio-add is a skill published in the GitHub repository meitu/meitu-skills (32 stars, last pushed 15d ago), licensed MIT. It adds 81 tokens to every session and 1,725 once invoked, about $0.0004 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.
