Security Scan

The skill's requirements and runtime instructions are coherent for an online cloud video-editing integration: it only needs a NEMO_TOKEN (or can obtain an anonymous token) and calls a remote nemovideo.ai API to upload, edit, and render videos.

Purpose & Capability

The skill's name/description align with its behavior: it calls a remote video-editing API and uploads user video files. Declared primary env var (NEMO_TOKEN) matches the API auth described. Minor inconsistency: the registry metadata shown earlier listed no required config paths, but the SKILL.md frontmatter declares a config path (~/.config/nemovideo/). This is a small metadata mismatch but does not change the overall purpose alignment.

Instruction Scope

SKILL.md instructs the agent to: use NEMO_TOKEN (or request an anonymous token), create sessions, upload files (either multipart from a local path or by URL), send SSE messages, poll render status, and return download URLs. These actions are within scope for a cloud video editor. Notes: uploading local file paths requires the agent to read local files (expected for uploading user videos). The spec also suggests detecting an install path to set an X-Skill-Platform header (this implies filesystem inspection of common install locations), which is reasonable but worth being aware of.

Install Mechanism

Instruction-only skill with no install spec and no code files — nothing is written to disk by an installer. This is the lowest-risk install model.

Credentials

Only one credential is required: NEMO_TOKEN (declared as primaryEnv). The SKILL.md also documents falling back to obtaining an anonymous token from the service if no token is present. No unrelated secrets or excessive env requirements are requested. The earlier metadata mismatch about configPaths is noted but the single credential is proportionate to the service.

Persistence & Privilege

always: false and disable-model-invocation: false (the skill may be invoked autonomously by the agent, which is the platform default). The skill does not request permanent presence or modify other skills. No elevated platform privileges are requested.

Assessment

This skill appears to legitimately wrap a cloud video-editing API (nemovideo.ai) and only needs a NEMO_TOKEN (or will request an anonymous token). Before installing: 1) Confirm you trust the nemovideo.ai service and its privacy policy—uploaded videos are sent to that remote server. 2) If you have sensitive content, do not upload it through this skill. 3) Be aware the agent may read local file paths you ask it to upload and may inspect common install paths to set a header (benign but worth knowing). 4) The SKILL.md frontmatter lists a config path (~/.config/nemovideo/) that the registry metadata did not — minor inconsistency; ask the publisher to clarify origin and expected config usage. If you are uncomfortable with autonomous invocation, restrict the skill’s permissions or require explicit user approval for each run.

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 editing.

Try saying:

• "edit a 2-minute raw screen recording into a 1080p MP4"
• "trim the pauses, add transitions, and export in 1080p"
• "quickly editing raw footage into a clean, shareable video online for content creators and marketers"

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.

Online Video Editor Best — Edit and Export Polished Videos

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

A quick example: upload a 2-minute raw screen recording, type "trim the pauses, add transitions, and export in 1080p", and you'll get a 1080p MP4 back in roughly 1-2 minutes. All rendering happens server-side.

Worth noting: shorter clips under 3 minutes process significantly faster.

Matching Input to Actions

User prompts referencing online video editor best, 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.

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

Headers are derived from this file's YAML frontmatter. X-Skill-Source is online-video-editor-best, 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).

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

• 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

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

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.

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 → "trim the pauses, add transitions, and export in 1080p" → 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 pauses, add transitions, and export in 1080p" — 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.
