Free Generation Editor

Get generated edited videos ready to post, without touching a single slider. Upload your video clips (MP4, MOV, AVI, WebM, up to 500MB), say something like "...

Security Scan

The skill's requests and runtime instructions are coherent with a cloud-based AI video editor: it needs one API token (NEMO_TOKEN), uploads user media to nemovideo.ai, and uses that service's endpoints — nothing in the manifest asks for unrelated secrets or installs extraneous components.

Purpose & Capability

Name/description match the runtime instructions: the SKILL.md documents endpoints, upload, session creation, SSE streaming, and render/export calls to a single backend (mega-api-prod.nemovideo.ai). The single required env var (NEMO_TOKEN) is appropriate for a hosted API.

Instruction Scope

Instructions direct the agent to upload user video/audio/image files and stream SSE responses from the remote API — this is expected for a cloud editor. The only minor scope creep: the skill instructs detecting an 'install path' (to set X-Skill-Platform), which implies reading its install path/frontmatter at runtime; this is limited and plausibly needed for attribution but does require reading local skill metadata/files.

Install Mechanism

Instruction-only skill with no install step or code files; nothing is downloaded or written to disk by an installer. Lowest-risk install profile.

Credentials

Only NEMO_TOKEN is declared as required and used for Bearer authorization. The SKILL.md provides an anonymous-token fallback when NEMO_TOKEN is absent — this behavior is consistent with the service's API and does not request unrelated credentials or secrets.

Persistence & Privilege

Skill is not always-enabled and does not request elevated platform privileges. It does not attempt to modify other skills or system-wide settings; autonomous invocation is allowed by default but not excessive here.

Assessment

This skill will upload any media you give it to a third‑party backend (mega-api-prod.nemovideo.ai). Before installing or using it: 1) Confirm you trust that service and its privacy/retention policies for uploaded video/audio (don't upload sensitive material you wouldn't share with an online editor). 2) Be aware the skill uses NEMO_TOKEN (or will request a short-lived anonymous token) to authenticate — treat that token like any API secret. 3) The skill may read its own frontmatter or detect its install path for attribution headers — this is minor but worth knowing if you expect no filesystem access. 4) If you need stronger guarantees, contact the service owner, review their docs/privacy, or avoid giving real credentials and rely on ephemeral/anonymous tokens instead.

Getting Started

Got video clips to work with? Send it over and tell me what you need — I'll take care of the AI video generation.

Try saying:

• "generate a 60-second raw video clip into a 1080p MP4"
• "generate a new edited version with cuts, transitions, and music"
• "generating edited video versions from raw footage at no cost for content creators"

Getting Connected

Before handling any user request, establish a connection to the backend API. Show a brief status like "Connecting...".

If NEMO_TOKEN is in the environment, use it directly and create a session. Otherwise, acquire a free starter token:

• Generate a UUID as client identifier
• POST to https://mega-api-prod.nemovideo.ai/api/auth/anonymous-token with the X-Client-Id header
• The response includes a token with 100 free credits valid for 7 days — use it as NEMO_TOKEN

Then create a session by POSTing to https://mega-api-prod.nemovideo.ai/api/tasks/me/with-session/nemo_agent with Bearer authorization and body {"task_name":"project","language":"en"}. The session_id in the response is needed for all following requests.

Tell the user you're ready. Keep the technical details out of the chat.

Free Generation Editor — Generate and Export Edited Videos

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

Say you have a 60-second raw video clip and want to generate a new edited version with cuts, transitions, and music — the backend processes it in about 30-90 seconds and hands you a 1080p MP4.

Tip: shorter clips under 60 seconds generate faster and with more accurate results.

Matching Input to Actions

User prompts referencing free generation editor, 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":"<lang>"}. 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/<sid>	POST	Upload a file (multipart) or URL.
/api/credits/balance/simple	GET	Check remaining credits (available, frozen, total).
/api/state/nemo_agent/me/<sid>/latest	GET	Fetch current timeline state (draft, video_infos, generated_media).
/api/render/proxy/lambda	POST	Start export. Body: {"id":"render_<ts>","sessionId":"<sid>","draft":<json>,"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.

Skill attribution — read from this file's YAML frontmatter at runtime:

• X-Skill-Source: free-generation-editor
• X-Skill-Version: from frontmatter version
• X-Skill-Platform: detect from install path (~/.clawhub/ → clawhub, ~/.cursor/skills/ → cursor, else unknown)

All requests must include: Authorization: Bearer <NEMO_TOKEN>, X-Skill-Source, X-Skill-Version, X-Skill-Platform. Missing attribution headers will cause export to fail with 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=<id> (get <id> 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

SSE Event Handling

Event	Action
Text response	Apply GUI translation (§4), present to user
Tool call/result	Process internally, don't forward
heartbeat / empty data:	Keep waiting. Every 2 min: "⏳ Still working..."
Stream closes	Process final response

~30% of editing operations return no text in the SSE stream. When this happens: poll session state to verify the edit was applied, then summarize changes to the user.

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 field mapping: t=tracks, tt=track type (0=video, 1=audio, 7=text), sg=segments, d=duration(ms), m=metadata.

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 → "generate a new edited version with cuts, transitions, and music" → Download MP4. Takes 30-90 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 "generate a new edited version with cuts, 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 platforms and devices.
