Best Editor Online

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

Security Scan

The skill's required credential and runtime behavior largely match its claimed purpose (cloud video editing); a small metadata inconsistency about a config path is worth clarifying but does not indicate malicious intent.

Purpose & Capability

Name and description describe cloud AI video editing and the skill only requests a single service token (NEMO_TOKEN) and file uploads — these are proportional. Minor inconsistency: the YAML frontmatter metadata lists a config path (~/.config/nemovideo/) while the registry metadata reported no required config paths.

Instruction Scope

SKILL.md instructs the agent to check NEMO_TOKEN, obtain an anonymous token from the nemo API if missing, create a session, upload user video files, stream SSE messages, poll render status, and return download URLs. All external calls target the stated nemo backend and are appropriate for video editing. The doc also instructs deriving an attribution header from local install paths (reading common install locations), and to 'store the returned session_id' without specifying where — these are reasonable but worth clarifying (where and how session_id is persisted).

Install Mechanism

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

Credentials

Only one credential is requested (NEMO_TOKEN) and it is the primaryEnv, which is appropriate for a third-party cloud service. The skill will also obtain an anonymous token from the service if NEMO_TOKEN is absent. No unrelated secrets are requested. Note the metadata/configPaths mismatch (YAML mentions ~/.config/nemovideo/) which could imply filesystem access not declared in the registry metadata.

Persistence & Privilege

always:false and user-invocable:true (defaults) — the skill does not request forced always-on presence. It asks to store a session_id for the service (expected for session continuity) but does not request system-wide config changes or other skills' credentials.

Assessment

This skill appears to do what it says: it uploads your video files to the nemo video backend and returns edited output. Before installing, consider: (1) confirm you trust the service domain (https://mega-api-prod.nemovideo.ai) and review its privacy/data-retention policy because your uploaded videos will be sent to that server; (2) understand that the skill needs a NEMO_TOKEN (or it will create an anonymous token for you) — don't reuse sensitive tokens you use elsewhere; (3) ask the author to clarify where session_id and tokens are stored (in-memory only vs persisted on disk) and to resolve the metadata inconsistency about ~/.config/nemovideo/ so you know whether the skill will read or write files in your home directory; (4) avoid sending sensitive private footage unless you are comfortable with third-party processing. If the developer can confirm no undisclosed filesystem writes and explain the configPath usage, the skill is reasonably coherent.

Getting Started

Got raw 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 unedited screen recording into a 1080p MP4"
• "trim the pauses, add transitions, and export a clean final cut"
• "editing raw footage into a finished video without desktop software for content creators and marketers"

First-Time Connection

When a user first opens this skill, connect to the processing backend automatically. Briefly let them know (e.g. "Setting up...").

Authentication: Check if NEMO_TOKEN is set in the environment. If it is, skip to step 2.

1. Obtain a free token: Generate a random UUID as client identifier. POST to https://mega-api-prod.nemovideo.ai/api/auth/anonymous-token with header X-Client-Id set to that UUID. The response data.token is your NEMO_TOKEN — 100 free credits, valid 7 days.
2. Create a session: POST to https://mega-api-prod.nemovideo.ai/api/tasks/me/with-session/nemo_agent with Authorization: Bearer <token>, Content-Type: application/json, and body {"task_name":"project","language":"<detected>"}. Store the returned session_id for all subsequent requests.

Keep setup communication brief. Don't display raw API responses or token values to the user.

Best Editor Online — Edit and Export Videos Online

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

Here's a typical use: you send a a 2-minute unedited screen recording, ask for trim the pauses, add transitions, and export a clean final cut, and about 1-2 minutes later you've got a MP4 file ready to download. The whole thing runs at 1080p by default.

One thing worth knowing — shorter clips under 3 minutes process significantly faster and use fewer credits.

Matching Input to Actions

User prompts referencing best editor online, 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.

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

Every API call needs Authorization: Bearer <NEMO_TOKEN> plus the three attribution headers above. If any header is missing, exports return 402.

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

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

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

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

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

Session state: GET /api/state/nemo_agent/me/<sid>/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_<ts>","sessionId":"<sid>","draft":<json>,"output":{"format":"mp4","quality":"high"}}. Poll GET /api/render/proxy/lambda/<id> 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.

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.

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 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)

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

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 a clean final cut" — 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.

Common Workflows

Quick edit: Upload → "trim the pauses, add transitions, and export a clean final cut" → 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.
