Description
Skip the learning curve of professional editing software. Describe what you want — convert this video to a different format without downloading any software...
README (SKILL.md)

Getting Started

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

Try saying:

  • "convert a 2-minute MP4 video file into a 1080p MP4"
  • "convert this video to a different format without downloading any software"
  • "converting video files to MP4 without installing software 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.

Converter Free — Convert Videos Online, No Download

Drop your video files in the chat and tell me what you need. I'll handle the AI format conversion on cloud GPUs — you don't need anything installed locally.

Here's a typical use: you send a a 2-minute MP4 video file, ask for convert this video to a different format without downloading any software, and about 30-60 seconds later you've got a MP4 file ready to download. The whole thing runs at 1080p by default.

One thing worth knowing — smaller file sizes convert faster, so compress before uploading if possible.

Matching Input to Actions

User prompts referencing converter free, 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.

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

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

Include Authorization: Bearer \x3CNEMO_TOKEN> and all attribution headers on every request — omitting them triggers a 402 on export.

Error Codes

  • 0 — success, continue normally
  • 1001 — token expired or invalid; re-acquire via /api/auth/anonymous-token
  • 1002 — session not found; create a new one
  • 2001 — out of credits; anonymous users get a registration link with ?bind=\x3Cid>, registered users top up
  • 4001 — unsupported file type; show accepted formats
  • 4002 — file too large; suggest compressing or trimming
  • 400 — missing X-Client-Id; generate one and retry
  • 402 — free plan export blocked; not a credit issue, subscription tier
  • 429 — rate limited; wait 30s and retry 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 → "convert this video to a different format without downloading any software" → 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 "convert this video to a different format without downloading any software" — 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.

Usage Guidance
This skill is broadly coherent for an online video-conversion service, but take these precautions before installing or using it: (1) Verify the backend domain (mega-api-prod.nemovideo.ai) and the service's privacy policy — uploaded media will go to that external server. (2) There is no homepage or clear publisher information in the registry; prefer skills with verifiable provenance. (3) The SKILL.md mentions a local config path (~/.config/nemovideo/) even though the registry metadata did not — ask the author whether the skill will read local config files or tokens. (4) Only set NEMO_TOKEN if you trust the service; otherwise rely on the anonymous-token flow for non-sensitive content. (5) Avoid uploading sensitive or private videos until you confirm retention/delete policies and can revoke tokens. If you want higher assurance, request the skill author/publisher info and a review of network endpoints and data handling before use.
Capability Analysis
Type: OpenClaw Skill Name: converter-free Version: 1.0.0 The skill is a functional wrapper for a cloud-based video conversion service hosted at nemovideo.ai. It defines standard API interactions for authentication, file uploading, and video rendering. While it requests access to a specific environment variable (NEMO_TOKEN) and a local config directory (~/.config/nemovideo/), these are consistent with its stated purpose of managing video processing sessions. No evidence of data exfiltration, unauthorized command execution, or malicious prompt injection was found in SKILL.md or _meta.json.
Capability Assessment
Purpose & Capability
The name/description (video conversion) align with the instructions and the single required env var (NEMO_TOKEN). However the SKILL.md frontmatter lists a config path (~/.config/nemovideo/) while the registry metadata provided earlier did not — this mismatch in declared config access is an inconsistency to clarify. Also there is no homepage or authoritative owner info, so provenance is weak.
Instruction Scope
Instructions are narrowly focused on creating a session, uploading files, streaming SSE results, and starting renders on the backend endpoints (mega-api-prod.nemovideo.ai). They explicitly tell the agent to upload user-supplied media and to generate anonymous tokens if NEMO_TOKEN is not present. The skill also instructs the agent to read attribution info (frontmatter and detect install path) which requires examining the agent environment — reasonable for attribution but worth noting.
Install Mechanism
This is an instruction-only skill with no install spec and no code files, so nothing is written to disk by an installer. That lowers install-time risk.
Credentials
Only one credential is declared (NEMO_TOKEN), which is proportionate for a service-backed converter. However the SKILL.md includes an anonymous-token acquisition flow (network POST to the service) and the frontmatter mentions a config path (~/.config/nemovideo/) not reflected in the registry metadata — this could allow the skill to read stored local tokens/config if implemented, so confirm whether that path will actually be accessed.
Persistence & Privilege
The skill does not request always:true and does not claim to modify other skills or system-wide settings. It can run network calls and be invoked autonomously (platform default), which is expected for an API-backed converter.
How to Use
  1. Make sure OpenClaw is installed (local or Docker)
  2. Run the install command in chat: /install converter-free
  3. After installation, invoke the skill by name or use /converter-free
  4. Provide required inputs per the skill's parameter spec and get structured output
