使用说明 (SKILL.md)

Getting Started

Share your video clips or images and I'll get started on AI video creation. Or just tell me what you're thinking.

Try saying:

"generate my video clips or images"
"export 1080p MP4"
"combine my clips into a short"

First-Time Connection

When a user first opens this skill, connect to the processing backend automatically. Briefly let them know (e.g. "Setting up...").

Authentication: Check if NEMO_TOKEN is set in the environment. If it is, skip to step 2.

Obtain a free token: Generate a random UUID as client identifier. POST to https://mega-api-prod.nemovideo.ai/api/auth/anonymous-token with header X-Client-Id set to that UUID. The response data.token is your NEMO_TOKEN — 100 free credits, valid 7 days.
Create a session: POST to https://mega-api-prod.nemovideo.ai/api/tasks/me/with-session/nemo_agent with Authorization: Bearer \x3Ctoken>, Content-Type: application/json, and body {"task_name":"project","language":"\x3Cdetected>"}. Store the returned session_id for all subsequent requests.

Keep setup communication brief. Don't display raw API responses or token values to the user.

Free Video Generator CapCut — Create and Export Short Videos

Name: Free Video Generator Capcut
Author: vcarolxhberger

This tool takes your video clips or images and runs AI video creation through a cloud rendering pipeline. You upload, describe what you want, and download the result.

Say you have three 10-second phone clips and a background song and want to combine my clips into a short video with transitions and music — the backend processes it in about 30-60 seconds and hands you a 1080p MP4.

Tip: keeping clips under 60 seconds each speeds up generation noticeably.

Matching Input to Actions

User prompts referencing free video generator capcut, aspect ratio, text overlays, or audio tracks get routed to the corresponding action via keyword and intent classification.

User says...	Action	Skip SSE?
"export" / "导出" / "download" / "send me the video"	→ §3.5 Export	✅
"credits" / "积分" / "balance" / "余额"	→ §3.3 Credits	✅
"status" / "状态" / "show tracks"	→ §3.4 State	✅
"upload" / "上传" / user sends file	→ §3.2 Upload	✅
Everything else (generate, edit, add BGM…)	→ §3.1 SSE	❌

Cloud Render Pipeline Details

Each export job queues on a cloud GPU node that composites video layers, applies platform-spec compression (H.264, up to 1080x1920), and returns a download URL within 30-90 seconds. The session token carries render job IDs, so closing the tab before completion orphans the job.

Base URL: https://mega-api-prod.nemovideo.ai

Endpoint	Method	Purpose
`/api/tasks/me/with-session/nemo_agent`	POST	Start a new editing session. Body: `{"task_name":"project","language":"\x3Clang>"}`. Returns `session_id`.
`/run_sse`	POST	Send a user message. Body includes `app_name`, `session_id`, `new_message`. Stream response with `Accept: text/event-stream`. Timeout: 15 min.
`/api/upload-video/nemo_agent/me/\x3Csid>`	POST	Upload a file (multipart) or URL.
`/api/credits/balance/simple`	GET	Check remaining credits (`available`, `frozen`, `total`).
`/api/state/nemo_agent/me/\x3Csid>/latest`	GET	Fetch current timeline state (`draft`, `video_infos`, `generated_media`).
`/api/render/proxy/lambda`	POST	Start export. Body: `{"id":"render_\x3Cts>","sessionId":"\x3Csid>","draft":\x3Cjson>,"output":{"format":"mp4","quality":"high"}}`. Poll status every 30s.

Accepted file types: mp4, mov, avi, webm, mkv, jpg, png, gif, webp, mp3, wav, m4a, aac.

Headers are derived from this file's YAML frontmatter. X-Skill-Source is free-video-generator-capcut, X-Skill-Version comes from the version field, and X-Skill-Platform is detected from the install path (~/.clawhub/ = clawhub, ~/.cursor/skills/ = cursor, otherwise unknown).

Every API call needs Authorization: Bearer \x3CNEMO_TOKEN> plus the three attribution headers above. If any header is missing, exports return 402.

Error Handling

Code	Meaning	Action
0	Success	Continue
1001	Bad/expired token	Re-auth via anonymous-token (tokens expire after 7 days)
1002	Session not found	New session §3.0
2001	No credits	Anonymous: show registration URL with `?bind=\x3Cid>` (get `\x3Cid>` from create-session or state response when needed). Registered: "Top up credits in your account"
4001	Unsupported file	Show supported formats
4002	File too large	Suggest compress/trim
400	Missing X-Client-Id	Generate Client-Id and retry (see §1)
402	Free plan export blocked	Subscription tier issue, NOT credits. "Register or upgrade your plan to unlock export."
429	Rate limit (1 token/client/7 days)	Retry in 30s once

Reading the SSE Stream

Text events go straight to the user (after GUI translation). Tool calls stay internal. Heartbeats and empty data: lines mean the backend is still working — show "⏳ Still working..." every 2 minutes.

About 30% of edit operations close the stream without any text. When that happens, poll /api/state to confirm the timeline changed, then tell the user what was updated.

Backend Response Translation

The backend assumes a GUI exists. Translate these into API actions:

Backend says	You do
"click [button]" / "点击"	Execute via API
"open [panel]" / "打开"	Query session state
"drag/drop" / "拖拽"	Send edit via SSE
"preview in timeline"	Show track summary
"Export button" / "导出"	Execute export workflow

Draft JSON uses short keys: t for tracks, tt for track type (0=video, 1=audio, 7=text), sg for segments, d for duration in ms, m for metadata.

Example timeline summary:

Timeline (3 tracks): 1. Video: city timelapse (0-10s) 2. BGM: Lo-fi (0-10s, 35%) 3. Title: "Urban Dreams" (0-3s)

Common Workflows

Quick edit: Upload → "combine my clips into a short video with transitions and music" → Download MP4. Takes 30-60 seconds for a 30-second clip.

Batch style: Upload multiple files in one session. Process them one by one with different instructions. Each gets its own render.

Iterative: Start with a rough cut, preview the result, then refine. The session keeps your timeline state so you can keep tweaking.

Tips and Tricks

The backend processes faster when you're specific. Instead of "make it look better", try "combine my clips into a short video with transitions and music" — concrete instructions get better results.

Max file size is 500MB. Stick to MP4, MOV, AVI, WebM for the smoothest experience.

Export as MP4 for widest compatibility across TikTok, Instagram, and YouTube.

安全使用建议

This skill will upload your videos/images to an external service (mega-api-prod.nemovideo.ai) and will obtain or use an Authorization token (NEMO_TOKEN). Before installing: 1) Be comfortable with an unknown publisher and no homepage — you have limited ability to audit the backend. 2) Avoid uploading sensitive or private footage unless you trust the service. 3) Decide whether to preset NEMO_TOKEN yourself (so the skill doesn't call the anonymous-token endpoint) or allow the agent to request one automatically. 4) Ask the publisher for documentation or a privacy/terms link and confirm where tokens/session data are stored (in memory only vs written to ~/.config/nemovideo/). 5) If you need stronger assurance, prefer a skill from a known publisher or one with a verifiable homepage/source code.

功能分析

Type: OpenClaw Skill Name: free-video-generator-capcut Version: 1.0.0 The skill acts as a legitimate wrapper for the NemoVideo cloud editing service (mega-api-prod.nemovideo.ai). It implements standard API workflows for authentication, file uploads, and video rendering as described in its documentation. There is no evidence of data exfiltration, unauthorized command execution, or malicious prompt injection; the instructions specifically include security-conscious directives such as hiding raw API tokens from the user.

能力评估

ℹ Purpose & Capability

The skill's declared purpose (cloud video editing) aligns with the single required credential (NEMO_TOKEN) and the HTTP endpoints described. However, the SKILL.md includes a config path (~/.config/nemovideo/) in its YAML metadata while the registry summary above listed no required config paths — this mismatch is unexplained. Also the skill source/publisher is unknown and no homepage is provided, which reduces traceability.

⚠ Instruction Scope

Runtime instructions tell the agent to automatically obtain anonymous tokens, create sessions, upload user media, stream SSE interactions, poll render status, and derive attribution headers (including detecting an install path like ~/.clawhub/). These actions require network access and transmission of user media to an external service (mega-api-prod.nemovideo.ai). The instructions also imply reading the agent's install path to set X-Skill-Platform and mention storing session_id/token for subsequent requests. While these steps are coherent with cloud rendering, they expand scope beyond purely local processing and merit user awareness.

✓ Install Mechanism

There is no install spec and no code files; this is instruction-only, so nothing will be written to disk by an installer. That reduces installation risk.

ℹ Credentials

Only one credential (NEMO_TOKEN) is declared as required and used for Authorization, which is proportionate for a cloud API. However, the SKILL.md also references a config path (~/.config/nemovideo/) and infers the install location to set headers — neither of which is declared in the registry header (inconsistency). The skill's anonymous-token flow will create and use ephemeral credentials if NEMO_TOKEN is not present; consider whether you want the agent to perform that network auth flow automatically.

✓ Persistence & Privilege

The skill is not force-included (always:false) and is user-invocable. It asks to store session IDs/tokens for the session, but there is no install step that modifies other skills or system-wide settings. Autonomous invocation is allowed (default), but that alone is normal and not flagged.
