Security Scan

The skill's requirements and runtime instructions are coherent with a cloud video-editing service: it needs a NEMO_TOKEN (or will obtain a short-lived anonymous token), talks only to a named backend domain, and has no install step or unexpected credential requests.

Purpose & Capability

The skill claims to perform cloud video editing and its instructions require a service token (NEMO_TOKEN), session creation, uploads, SSE chat, state polling, and render/export endpoints on a nemovideo.ai domain — all expected for a hosted video editor. The declared config path (~/.config/nemovideo/) and primaryEnv NEMO_TOKEN align with that purpose.

Instruction Scope

Most runtime steps (create session, upload files, poll render status, read SSE) are narrowly scoped to the editing workflow. Minor scope items to note: it instructs the agent to read this skill's YAML frontmatter at runtime and to detect the agent install path (e.g., checking ~/.clawhub/ or ~/.cursor/skills/) to set X-Skill-Platform — this requires filesystem access to the agent environment and is not strictly necessary for core editing but is plausible for attribution headers. No instructions ask for unrelated system files or other credentials.

Install Mechanism

There is no install spec and no code files; the skill is instruction-only. That is the lowest-risk install model — nothing is downloaded or written to disk by an install step.

Credentials

Only one credential is required (NEMO_TOKEN) and it is used as a Bearer token for all API calls. The skill also offers to fetch a short-lived anonymous token if NEMO_TOKEN is absent, which is consistent with a public service offering free starter credits. The declared config path is for this service's configuration and is proportionate.

Persistence & Privilege

The skill does not request always:true and does not modify other skills or system-wide settings. It runs remotely and relies on the service for rendering; no elevated persistence or system-wide privileges are requested.

Assessment

This skill appears internally consistent with a cloud video-editing service. Before installing/using it, consider: - Understand that your video files and a Bearer token (NEMO_TOKEN) will be sent to https://mega-api-prod.nemovideo.ai; only upload non-sensitive content and review the service's privacy/terms if available. - If you don't want to expose a long-lived token, prefer using an anonymous starter token or create a dedicated, limited token/account you can rotate or revoke. - The skill may read the skill file's frontmatter and probe typical install paths to populate attribution headers — this requires filesystem access in the agent environment. If you run agents with restricted FS access, confirm whether those reads are permitted. - Confirm file-size and retention policy with the service (the description references up to 500MB and ~1–2 minute processing; SKILL.md also recommends clips under 3 minutes). If you want a stricter assessment, provide the agent runtime environment details (what file-system access the agent has, whether outbound network calls are allowed, and whether you control the NEMO_TOKEN) — that could change the risk characterization.

Getting Started

Send me your raw video clips and I'll handle the AI-assisted video editing. Or just describe what you're after.

Try saying:

• "edit a 2-minute smartphone recording from a birthday party into a 1080p MP4"
• "trim the shaky parts, add transitions, and put background music"
• "turning raw footage into a finished video without editing experience for beginners and casual 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.

Video Editor for Beginners Free — Edit and Export Videos Easily

Send me your raw video clips and describe the result you want. The AI-assisted video editing runs on remote GPU nodes — nothing to install on your machine.

A quick example: upload a 2-minute smartphone recording from a birthday party, type "trim the shaky parts, add transitions, and put background music", and you'll get a 1080p MP4 back in roughly 1-2 minutes. All rendering happens server-side.

Worth noting: keep clips under 3 minutes for the fastest processing and best AI results.

Matching Input to Actions

User prompts referencing video editor for beginners 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.

All calls go to https://mega-api-prod.nemovideo.ai. The main endpoints:

1. Session — POST /api/tasks/me/with-session/nemo_agent with {"task_name":"project","language":"<lang>"}. Gives you a session_id.
2. Chat (SSE) — POST /run_sse with session_id and your message in new_message.parts[0].text. Set Accept: text/event-stream. Up to 15 min.
3. Upload — POST /api/upload-video/nemo_agent/me/<sid> — multipart file or JSON with URLs.
4. Credits — GET /api/credits/balance/simple — returns available, frozen, total.
5. State — GET /api/state/nemo_agent/me/<sid>/latest — current draft and media info.
6. Export — POST /api/render/proxy/lambda with render ID and draft JSON. Poll GET /api/render/proxy/lambda/<id> every 30s for completed status and download URL.

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

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

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)

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.

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=<id>, 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

Common Workflows

Quick edit: Upload → "trim the shaky parts, add transitions, and put background music" → Download MP4. Takes 1-2 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 "trim the shaky parts, add transitions, and put background 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 social platforms and devices.
