0. First Contact

When the user opens this skill or sends their first message, greet them immediately:

🚀 Ready to tiktok video editor online! Just send me a video or describe your project.

Try saying:

• "make it look cinematic"
• "add a fade-in transition"
• "speed up by 2x"

IMPORTANT: Do NOT wait silently. Always greet the user proactively on first contact.

Auto-Setup (do this SILENTLY before anything else)

Before responding to the user, complete these steps invisibly:

1. Check token: If NEMO_TOKEN env var is set, use it. Otherwise:
2. Read or generate Client-ID:
   • Read ~/.config/nemovideo/client_id if it exists
   • Otherwise generate a UUID, save it to ~/.config/nemovideo/client_id
3. Acquire anonymous token:

   curl -s -X POST "$API/api/auth/anonymous-token" -H "X-Client-Id: $CLIENT_ID"
   

   Store the returned token as NEMO_TOKEN for this session. You get 100 free credits.
4. Create a session (§3.0) so you're ready to work immediately.

CRITICAL: Never mention tokens, authentication, API setup, or Client-IDs to the user. The user should feel like the skill "just works".

Chat Your Way to a TikTok-Ready Video

Most video editors were built for filmmakers, not for someone trying to post before a trend dies. The tiktok-video-editor-online skill flips that assumption — instead of dragging clips across a timeline, you describe what you want in plain language and the edit happens. Say 'trim the first 3 seconds, add captions in bold white, and crop to 9:16' and that's exactly what you get.

Under the hood, the OpenClaw agent interprets your natural language instructions and maps them to precise video manipulation operations. It understands TikTok-specific context — vertical formats, short attention spans, caption placement that doesn't get cut off by the UI, and pacing that matches the platform's rhythm. The agent handles sequencing of multiple edits in a single pass, so you're not going back and forth through menus.

This skill is especially useful for creators who batch-produce content, repurpose longer footage into short clips, or need to quickly react to trending audio. Whether you're cutting a 60-second highlight from a livestream or adding text hooks to a raw clip, the conversational model keeps you focused on the content rather than the software.

Environment Variables

Variable	Required	Default
NEMO_TOKEN	No	Auto-generated (100 free credits, expires in 7 days, revocable via Settings → API Tokens)
NEMO_API_URL	No	https://mega-api-prod.nemovideo.ai
NEMO_WEB_URL	No	https://nemovideo.com
NEMO_CLIENT_ID	No	Auto-generated UUID, persisted to ~/.config/nemovideo/client_id (UUID only, no secrets)
SKILL_SOURCE	No	Auto-detected from install path, fallback unknown

If NEMO_TOKEN is not set, get one (requires X-Client-Id header):

# Generate or read persisted Client-Id
CLIENT_ID="${NEMO_CLIENT_ID:-$(cat ~/.config/nemovideo/client_id 2>/dev/null)}"
if [ -z "$CLIENT_ID" ]; then
  CLIENT_ID=$(uuidgen 2>/dev/null || echo "client-$(date +%s)-$RANDOM")
  mkdir -p ~/.config/nemovideo && echo "$CLIENT_ID" > ~/.config/nemovideo/client_id
fi
curl -s -X POST "$API/api/auth/anonymous-token" -H "X-Client-Id: $CLIENT_ID"
# → {"code":0,"data":{"token":"nmv_usr_xxx","credits":100,...}}

Save token as NEMO_TOKEN, CLIENT_ID as NEMO_CLIENT_ID. Anonymous: 1 token per client per 7 days; token expires in 7 days and can be revoked at any time via Settings → API Tokens on nemovideo.com. If your token expires, request a new one with the same X-Client-Id.

Local persistence: This skill writes ~/.config/nemovideo/client_id to persist the Client-Id across sessions. This avoids generating a new ID on every request, which would hit the per-IP rate limit quickly (default 10 tokens per 7 days per IP). The file contains only a UUID — no credentials are stored locally.

2. Routing Incoming Requests to the Correct Endpoint

Use the table below to determine which API endpoint should handle each type of incoming request.

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	❌

3. Primary Workflow Implementations

$API = ${NEMO_API_URL:-https://mega-api-prod.nemovideo.ai}, $TOKEN = ${NEMO_TOKEN}, $WEB = ${NEMO_WEB_URL:-https://nemovideo.com}.

Skill attribution variables — do NOT hardcode:

• $SKILL_NAME = this file's YAML frontmatter name
• $SKILL_VERSION = this file's YAML frontmatter version
• $SKILL_SOURCE = detect at runtime using the first match:
  1. Env SKILL_SOURCE if set
  2. If this file's path contains a known platform directory (e.g. ~/.clawhub/ → clawhub, ~/.cursor/skills/ → cursor)
  3. Fallback: unknown

CRITICAL: ALL API requests (including render/export/upload/state/credits) MUST include these headers. Missing them will cause export to fail with 402.

X-Skill-Source: $SKILL_NAME
X-Skill-Version: $SKILL_VERSION
X-Skill-Platform: $SKILL_SOURCE

3.0 Initializing a New Session

curl -s -X POST "$API/api/tasks/me/with-session/nemo_agent" \
  -H "Authorization: Bearer $TOKEN" -H "Content-Type: application/json" \
  -H "X-Skill-Source: $SKILL_NAME" -H "X-Skill-Version: $SKILL_VERSION" -H "X-Skill-Platform: $SKILL_SOURCE" \
  -d '{"task_name":"project","language":"<lang>"}'
# → {"code":0,"data":{"task_id":"...","session_id":"..."}}

Before any editing actions can occur, a session must be established with the backend. All subsequent requests within the same editing context must reference the session identifier returned during this step.

Open in browser: After creating a session, give the user a link to view/edit the task in NemoVideo: $WEB/workspace/claim?token=$TOKEN&task={task_id}&session={session_id}&skill_name=$SKILL_NAME&skill_version=$SKILL_VERSION&skill_source=$SKILL_SOURCE

3.1 Delivering Messages Through SSE

curl -s -X POST "$API/run_sse" \
  -H "Authorization: Bearer $TOKEN" -H "Content-Type: application/json" \
  -H "Accept: text/event-stream" -H "X-Skill-Source: $SKILL_NAME" -H "X-Skill-Version: $SKILL_VERSION" -H "X-Skill-Platform: $SKILL_SOURCE" --max-time 900 \
  -d '{"app_name":"nemo_agent","user_id":"me","session_id":"<sid>","new_message":{"parts":[{"text":"<msg>"}]}}'

All conversational messages to the editing backend are transmitted via Server-Sent Events, which stream responses back incrementally as they become available.

SSE Handling

Event	Action
Text response	Apply GUI translation (§4), present to user
Tool call/result	Wait silently, don't forward
heartbeat / empty data:	Keep waiting. Every 2 min: "⏳ Still working..."
Stream closes	Process final response

Typical durations: text 5-15s, video generation 100-300s, editing 10-30s.

Timeout: 10 min heartbeats-only → assume timeout. Never re-send during generation (duplicates + double-charge).

Ignore trailing "I encountered a temporary issue" if prior responses were normal.

Silent Response Fallback (CRITICAL)

Approximately 30% of editing operations complete without returning any text in the SSE stream. When no text content is received after the stream closes, do not treat this as an error or prompt the user to retry. Instead, immediately call the state query endpoint to check the current project status, surface the resulting state to the user, and continue the conversation from there.

Two-stage generation: When a raw video is produced by the backend, an automated second stage triggers without any user input — the system appends background music and a title overlay before finalizing the output. Your integration must account for both stages: first await the raw video event, then wait for the enrichment stage to complete before presenting the final result to the user.

3.2 Handling Asset Uploads

File upload: curl -s -X POST "$API/api/upload-video/nemo_agent/me/<sid>" -H "Authorization: Bearer $TOKEN" -H "X-Skill-Source: $SKILL_NAME" -H "X-Skill-Version: $SKILL_VERSION" -H "X-Skill-Platform: $SKILL_SOURCE" -F "files=@/path/to/file"

URL upload: curl -s -X POST "$API/api/upload-video/nemo_agent/me/<sid>" -H "Authorization: Bearer $TOKEN" -H "Content-Type: application/json" -H "X-Skill-Source: $SKILL_NAME" -H "X-Skill-Version: $SKILL_VERSION" -H "X-Skill-Platform: $SKILL_SOURCE" -d '{"urls":["<url>"],"source_type":"url"}'

Use me in the path; backend resolves user from token.

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

The upload endpoint accepts media files that users wish to incorporate into their editing projects.

3.3 Checking Available Credits

curl -s "$API/api/credits/balance/simple" -H "Authorization: Bearer $TOKEN" \
  -H "X-Skill-Source: $SKILL_NAME" -H "X-Skill-Version: $SKILL_VERSION" -H "X-Skill-Platform: $SKILL_SOURCE"
# → {"code":0,"data":{"available":XXX,"frozen":XX,"total":XXX}}

Query the credits endpoint to retrieve the user's current balance before initiating any operation that consumes credits.

3.4 Retrieving Current Project State

curl -s "$API/api/state/nemo_agent/me/<sid>/latest" -H "Authorization: Bearer $TOKEN" \
  -H "X-Skill-Source: $SKILL_NAME" -H "X-Skill-Version: $SKILL_VERSION" -H "X-Skill-Platform: $SKILL_SOURCE"

Use me for user in path; backend resolves from token. Key fields: data.state.draft, data.state.video_infos, data.state.canvas_config, data.state.generated_media.

Draft field mapping: t=tracks, tt=track type (0=video, 1=audio, 7=text), sg=segments, d=duration(ms), m=metadata.

Draft ready for export when draft.t exists with at least one track with non-empty sg.

Track summary format:

Timeline (3 tracks): 1. Video: city timelapse (0-10s) 2. BGM: Lo-fi (0-10s, 35%) 3. Title: "Urban Dreams" (0-3s)

3.5 Triggering Export and Delivering the Result

Export does NOT cost credits. Only generation/editing consumes credits.

Exporting a finished project does not deduct from the user's credit balance. The export flow proceeds as follows: (a) call the export endpoint with the session identifier, (b) poll or listen for the export job status, (c) wait for the completed status event, (d) extract the download URL from the response payload, and (e) present the URL to the user as the final deliverable.

b) Submit: curl -s -X POST "$API/api/render/proxy/lambda" -H "Authorization: Bearer $TOKEN" -H "Content-Type: application/json" -H "X-Skill-Source: $SKILL_NAME" -H "X-Skill-Version: $SKILL_VERSION" -H "X-Skill-Platform: $SKILL_SOURCE" -d '{"id":"render_<ts>","sessionId":"<sid>","draft":<json>,"output":{"format":"mp4","quality":"high"}}'

Note: sessionId is camelCase (exception). On failure → new id, retry once.

c) Poll (every 30s, max 10 polls): curl -s "$API/api/render/proxy/lambda/<id>" -H "Authorization: Bearer $TOKEN" -H "X-Skill-Source: $SKILL_NAME" -H "X-Skill-Version: $SKILL_VERSION" -H "X-Skill-Platform: $SKILL_SOURCE"

Status at top-level status: pending → processing → completed / failed. Download URL at output.url.

d) Download from output.url → send to user. Fallback: $API/api/render/proxy/<id>/download.

e) When delivering the video, always also give the task detail link: $WEB/workspace/claim?token=$TOKEN&task={task_id}&session={session_id}&skill_name=$SKILL_NAME&skill_version=$SKILL_VERSION&skill_source=$SKILL_SOURCE

Progress messages: start "⏳ Rendering ~30s" → "⏳ 50%" → "✅ Video ready!" + file + task detail link.

3.6 Recovering from an SSE Disconnection

If the SSE connection drops before the stream completes, follow these recovery steps: (1) Detect the disconnection via a connection-close or error event on the stream. (2) Wait a brief interval before attempting to reconnect to avoid hammering the server. (3) Re-establish the SSE connection using the same session identifier. (4) Call the state query endpoint to determine what progress was made before the disconnect. (5) Resume the conversation from the last confirmed state, informing the user only if meaningful context was lost.

4. Translating Backend GUI References for Users

The backend is designed around a graphical interface and will occasionally reference UI elements in its responses — never pass these GUI-specific instructions through to the user verbatim; instead, translate them into plain conversational language.

Backend says	You do
"click [button]" / "点击"	Execute via API
"open [panel]" / "打开"	Show state via §3.4
"drag/drop" / "拖拽"	Send edit via SSE
"preview in timeline"	Show track summary
"Export button" / "导出"	Execute §3.5
"check account/billing"	Check §3.3

Keep content descriptions. Strip GUI actions.

5. Recommended Interaction Patterns

• Always confirm the user's creative intent before dispatching an edit request, especially for destructive operations like trimming or replacing clips. • After each backend response, summarize what changed in plain language rather than echoing raw API output. • When a silent response occurs, proactively fetch project state and present it as a natural continuation of the conversation. • If the user asks about progress mid-operation, query the state endpoint and relay the status in friendly, non-technical terms. • Offer to export only after confirming the user is satisfied with the current edit, and remind them that exporting is free.

6. Known Constraints and Limitations

• The backend does not support real-time collaborative editing; only one active session per user is permitted at a time. • File uploads are subject to size and format restrictions defined by the upload endpoint — validate these before sending. • Credit balances are read-only through this integration; top-ups must be handled through the platform's billing interface. • SSE streams may time out on long-running operations; implement the disconnection recovery flow as a standard safeguard. • The two-stage BGM and title enrichment process cannot be skipped or configured through the API.

7. Error Handling Reference

The table below maps HTTP status codes and backend error identifiers to their recommended handling behavior.

Code	Meaning	Action
0	Success	Continue
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=<id> (get <id> from create-session or state response when needed). Registered: "Top up at nemovideo.ai"
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 at nemovideo.ai to unlock export."
429	Rate limit (1 token/client/7 days)	Retry in 30s once

Common: no video → generate first; render fail → retry new id; SSE timeout → §3.6; silent edit → §3.1 fallback.

8. API Version and Required Token Scopes

Before going live, confirm that the integration targets the correct API version by checking the version field in the service's discovery response. The access token provided during session creation must include all required scopes for editing, upload, export, and credits endpoints — requests made with a token missing any of these scopes will be rejected with a 403 response. If a version mismatch is detected, halt the flow and surface a clear message to the user rather than proceeding with potentially incompatible calls.
