description

Autonomously manage the CATIMATION portrait library (人像库 / 素材库) — the persistent, deduplicated pool of image / video / audio reference assets that keeps characters & scenes consistent. Use when the user mentions 人像库 / 素材库 / 参考素材 / 角色库, wants to save / 收藏 / 搜索 / 整理 / 重命名 / 分组 / 删除 / 下载 a reference asset, or when a reference asset is needed for 视频生成 / video generation. Add, search, organize, rename, group, hide, download proactively.

Autonomously manage the CATIMATION portrait library (人像库)

The portrait library is a persistent, content-deduplicated pool of image / video / audio assets. It feeds generate_video (reference images, first/last frames) and keeps the SAME character or scene consistent across clips. Four catimation MCP tools let you manage it — use them proactively; you do not need permission to add, search, organize, or download on the user's behalf.

When to Use

• 用户提到 人像库 / 素材库 / 参考素材 / 角色库,要 收藏 / 搜索 / 整理 / 重命名 / 分组 / 删除 / 下载 素材。
• 视频生成需要参考素材(角色 / 场景一致性)→ 先入库拿 asset://assetId 再喂 generate_video(视频/音频类素材先用 ffmpeg-win 抽静帧/抽音轨再入库当参考,不直传原始视频)。
• 用户要复用「上次那个人 / 同一个角色 / 同一个场景」→ 先 list_portrait_library 找回锚点。
• 用户喜欢刚生成的图、之后可能复用 → 主动入库。

Tools

• add_to_portrait_library — upload ONE asset. source may be a local file path, data: URL, https URL, or an existing asset://assetId. Kind (image/video/audio) is auto-detected (override with kind); for people use imageCategory: image_people (default). Identical content dedupes to the same assetId. Returns { assetId, assetUrl, name, duplicated }. 图像 asset 的 assetUrl (asset://…) 可直传 generate_video;但视频/音频 asset 不直接当视觉参考 ——先用 ffmpeg-win 抽干净关键帧 / 拼宫格图(或抽音轨),把静帧 / 音频入库再喂,原始 视频仅留底(尤其是 Seedance 自产片段,整段回喂会二次编码、画质打折)。
• list_portrait_library — search / browse. Optional query (name text), kind (all/image_people/image_environment/video/audio), group, page, pageSize, includeHidden. Returns items with assetId, display name, kind, custom group, and asset://assetId. This is how you FIND material and look up assetIds before editing/downloading.
• edit_portrait_library — organize via action: rename (assetId + name), move_group (assetIds + group; omit group to ungroup), hide / unhide (assetIds; hide = soft-delete, recoverable), new_group / delete_group (group). Edits appear live on the user's 人像库 page.
• download_portrait_asset — save an asset locally; pass the sourceUrl from list_portrait_library. Returns the saved local path.

审核闸门(上传后别立刻拿去生成 ⚠️)

add_to_portrait_library 上传新素材后,上游会先做内容审核(审核)。审核 未通过 / 仍在审核中的素材,直接把它的 asset://assetId 喂给 generate_video 会让生成任务直接失败(如 内容审核未通过 / 素材不可用)。所以:

• ✅ 复用库里已存在的素材最稳——它们早已审核通过。
• ✅ add_to_portrait_library 返回 duplicated: true = 命中去重 = 已在库 = 已审核,可以立刻用。
• ⛔ 全新上传(duplicated: false)不要审核没过就抢着生成:先确认审核通过 ——用 list_portrait_library 能正常查到、人像库页面对该素材无「审核中 / 待审核」 标记后再 generate_video;或直接告诉用户「素材正在审核,通过后再生成」并停下, 不要赌它已通过。
• 一句话:先入库 → 等审核过 → 再生成,顺序不能颠倒。

Proactive workflows

1. User mentions video generation with material → add_to_portrait_library each provided image/video/audio FIRST. Then — only after it clears review (see 审核闸门 above; a duplicated:true result is already reviewed) — reference the returned asset://assetId in generate_video. (Images passed directly to generate_video are auto-imported; videos/audio and any "save for later" material are on you.)
2. Reuse a character/scene ("还是上次那个人 / 同一个角色 / 同一个场景") → list_portrait_library to find the matching asset://assetId, then reference it — this is what keeps identity consistent.
3. User likes a generated image and may reuse it → proactively add_to_portrait_library it (imageCategory: image_people for people).
4. Tidy up → give new assets clear names (rename) and group related material (new_group + move_group) when it helps the user find things.
5. Save/export → list_portrait_library to get the sourceUrl, then download_portrait_asset.

Notes

• The library can be LARGE. list_portrait_library is paginated — narrow first with query/kind/group, read the returned page/totalPages/hasMore, and when hasMore is true page through with page:N+1. Do NOT crank up pageSize to dump everything (large results get truncated and waste context).
• Always list_portrait_library to obtain assetId / sourceUrl before any edit_portrait_library or download_portrait_asset call — do not guess ids.
• All four tools need the Seedance API Key AND API Secret configured (Settings → Seedance; the library interface is HMAC-signed). If missing, the tool tells you to ask the user to set them — relay that and stop.
• Renaming / grouping / hiding is a local organizing layer shared with the UI; it never deletes upstream data (hide is reversible via unhide).

Common Mistakes

• 新上传的素材审核没过就抢着 generate_video(任务必失败):见上「审核闸门」, 先等审核通过(或复用 duplicated:true 的已审核素材)再生成。
• 凭空猜 assetId / sourceUrl;必须先 list_portrait_library 查到再用。
• 漏 list 直接 edit_portrait_library / download_portrait_asset。
• 调高 pageSize 一次性 dump 整库(结果会被截断、浪费上下文),应先用 query/kind/group 收窄再翻页。
• 缺 API Key/Secret 仍硬调;缺失时转告用户去设置并停下。
