Token cost

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.

Security

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 2mo 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:

  1. 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)。
  2. 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。

API Mapping

场景 API name
添加背景音乐 video_bgm_add
添加旁白配音 video_narration_add

Dependencies

  • meitu-cli: >=2.0.6
  • 凭证:CONFIG AKSK → meitu tools update;EXEC AKSK → 跑命令
  • 环境变量:MEITU_OPENAPI_TOOL_TASK_MODE=command

路径别名: 下文中 $VISUAL = {OPENCLAW_HOME}/workspace/visual/

Core Workflow

Preflight → Execute → Deliver

Preflight

  1. meitu --version → 未安装则提示安装
  2. meitu auth verify --json → 凭证无效则引导配置
  3. 检测 MEITU_OPENAPI_TOOL_TASK_MODE=command 是否设置
  4. 解析 output_dir:项目模式 → ./output/;一次性 → $VISUAL/output/video-audio-add/;mkdir -p

Execute

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

参数定义

通用参数:

参数 类型 必填 范围 默认 说明
video_list ARRAY[STRING] 是 — — 视频地址列表
prompt STRING 是 — — BGM:音乐风格偏好;旁白:旁白文案 + 音色

video_bgm_add 额外:

参数 类型 必填 范围 默认 说明
audio_url STRING 否 — — 自定义音频 URL;存在时跳过内部素材检索
music_volume NUMBER 否 0–1 1 背景音乐音量
video_volume NUMBER 否 0–1 1 原声音量(默认不压低)

video_narration_add 额外:

参数 类型 必填 范围 默认 说明
video_volume NUMBER 否 0–1 0 原声音量(默认压低)

说明:bgm_material_id / voice_material_id 不作为外部入参,由工具内部根据 prompt 自动检索;无匹配则使用默认素材/音色。

工具调用

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.
