Description
generate text prompts or images into AI-generated video clips with this skill. Works with PNG, JPG, MP4, WebM files up to 200MB. indie creators and ComfyUI e...
README (SKILL.md)

Getting Started

Ready when you are. Drop your text prompts or images here or describe what you want to make.

Try saying:

  • "generate a landscape photo with a motion prompt into a 1080p MP4"
  • "generate a 5-second video of ocean waves crashing on a beach"
  • "generating short AI videos from text or image prompts without paying for tools for indie creators and ComfyUI enthusiasts"

Automatic Setup

On first interaction, connect to the processing API before doing anything else. Show a brief status like "Setting things up...".

Token: If NEMO_TOKEN environment variable is already set, use it and skip to Session below.

Free token: Generate a UUID as client identifier, then POST to https://mega-api-prod.nemovideo.ai/api/auth/anonymous-token with header X-Client-Id: \x3Cuuid>. The response field data.token becomes your NEMO_TOKEN (100 credits, 7-day expiry).

Session: POST to https://mega-api-prod.nemovideo.ai/api/tasks/me/with-session/nemo_agent with Bearer auth and body {"task_name":"project"}. Save session_id from the response.

Confirm to the user you're connected and ready. Don't print tokens or raw JSON.

Free Video Generation ComfyUI — Generate AI Videos From Prompts

Drop your text prompts or images in the chat and tell me what you need. I'll handle the AI video generation on cloud GPUs — you don't need anything installed locally.

Here's a typical use: you send a a landscape photo with a motion prompt, ask for generate a 5-second video of ocean waves crashing on a beach, and about 1-3 minutes later you've got a MP4 file ready to download. The whole thing runs at 1080p by default.

One thing worth knowing — shorter prompt descriptions with clear motion cues produce more consistent results.

Matching Input to Actions

User prompts referencing free video generation comfyui, 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.

All requests must include: Authorization: Bearer \x3CNEMO_TOKEN>, X-Skill-Source, X-Skill-Version, X-Skill-Platform. Missing attribution headers will cause export to fail with 402.

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

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

API base: https://mega-api-prod.nemovideo.ai

Create session: POST /api/tasks/me/with-session/nemo_agent — body {"task_name":"project","language":"\x3Clang>"} — returns task_id, session_id.

Send message (SSE): POST /run_sse — body {"app_name":"nemo_agent","user_id":"me","session_id":"\x3Csid>","new_message":{"parts":[{"text":"\x3Cmsg>"}]}} with Accept: text/event-stream. Max timeout: 15 minutes.

Upload: POST /api/upload-video/nemo_agent/me/\x3Csid> — file: multipart -F "files=@/path", or URL: {"urls":["\x3Curl>"],"source_type":"url"}

Credits: GET /api/credits/balance/simple — returns available, frozen, total

Session state: GET /api/state/nemo_agent/me/\x3Csid>/latest — key fields: data.state.draft, data.state.video_infos, data.state.generated_media

Export (free, no credits): POST /api/render/proxy/lambda — body {"id":"render_\x3Cts>","sessionId":"\x3Csid>","draft":\x3Cjson>,"output":{"format":"mp4","quality":"high"}}. Poll GET /api/render/proxy/lambda/\x3Cid> every 30s until status = completed. Download URL at output.url.

Supported formats: mp4, mov, avi, webm, mkv, jpg, png, gif, webp, mp3, wav, m4a, aac.

Error Handling

Code Meaning Action

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

Translating GUI Instructions

The backend responds as if there's a visual interface. Map its instructions to API calls:

  • "click" or "点击" → execute the action via the relevant endpoint
  • "open" or "打开" → query session state to get the data
  • "drag/drop" or "拖拽" → send the edit command through SSE
  • "preview in timeline" → show a text summary of current tracks
  • "Export" or "导出" → run the export workflow

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.

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 → "generate a 5-second video of ocean waves crashing on a beach" → Download MP4. Takes 1-3 minutes 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 5-second video of ocean waves crashing on a beach" — concrete instructions get better results.

Max file size is 200MB. Stick to PNG, JPG, MP4, WebM for the smoothest experience.

Export as MP4 with H.264 codec for widest platform compatibility.

Usage Guidance
This skill generally does what it says (calls an external rendering API), but check these before installing: 1) Confirm you trust the API host (mega-api-prod.nemovideo.ai) because your uploads (images, video) and any token will be sent there. 2) Prefer using a throwaway/anonymous token rather than a long-lived or high-privilege token; the skill can generate a short-lived anonymous token automatically. 3) Ask the author how/where tokens and session IDs are persisted — the SKILL.md suggests saving session IDs and references a config path in its frontmatter; if they are written to disk (e.g., ~/.config/nemovideo/) consider the privacy implications. 4) If you do not want the skill to probe your home directories for install-path detection, do not grant filesystem access or run it in a restricted environment. 5) If unsure about the domain or persistence behavior, do not install or only test in an isolated account/environment.
Capability Analysis
Type: OpenClaw Skill Name: free-video-generation-comfyui Version: 1.0.0 The skill 'free-video-generation-comfyui' is a legitimate integration for a cloud-based video generation service (nemovideo.ai). It provides instructions for the AI agent to manage authentication, session handling, file uploads, and polling for rendered video results. All network activities and file handling are strictly aligned with the stated purpose of generating AI videos, and the instructions include security-conscious directives such as not printing raw tokens or JSON to the user. No indicators of data exfiltration, persistence, or malicious intent were found.
Capability Assessment
Purpose & Capability
The name/description (ComfyUI-style free video generation) matches the API calls and flows in SKILL.md. Requiring a single NEMO_TOKEN is proportionate for an external render API. However, the SKILL.md frontmatter includes a config path (~/.config/nemovideo/) while the registry metadata reported no required config paths — this discrepancy is unexplained and worth clarifying.
Instruction Scope
Runtime instructions tell the agent to obtain or use NEMO_TOKEN, create sessions, upload local files (multipart with local file paths or URLs), and poll SSE endpoints. That is expected for a cloud-render skill. Concerns: (1) the doc instructs to 'save session_id' and to use/issue tokens (anonymous-token flow) but does not specify where/how to persist them (in-memory vs disk), (2) it tells the agent to detect install path by probing home directories (~/.clawhub/, ~/.cursor/skills/), which requires reading the user's filesystem beyond just the files the user intentionally uploads. These behaviors increase the chance that tokens or IDs could be persisted or that the skill will read unexpected files.
Install Mechanism
This is an instruction-only skill with no install spec and no code files — lowest install risk. No downloads or package installs are requested.
Credentials
Only NEMO_TOKEN is declared as required (primary credential), which is consistent with calling the nemo API. The SKILL.md also defines an anonymous-token flow when NEMO_TOKEN is absent (generating a client UUID and exchanging it for a short-lived token) — reasonable but means the skill can obtain credentials autonomously. The mismatch between the registry's 'no config paths' and the SKILL.md frontmatter listing ~/.config/nemovideo/ is unexplained and should be clarified (could indicate where tokens/sessions are saved).
Persistence & Privilege
The skill does not set always:true and allows model invocation (normal). However, instructions explicitly say to 'save session_id' and to reuse or refresh tokens (anonymous or provided). Because the skill is instruction-only the mechanism/location for persistence is unclear — if the agent stores NEMO_TOKEN or session IDs to disk (e.g., ~/.config/nemovideo/), that raises longer-term persistence/privacy concerns. No explicit request to modify other skills or system-wide settings is present.
