๐Ÿ“– About This Skill


name: game-music-maker version: "1.0.0" displayName: "Game Music Maker โ€” Generate Music for Game Videos" description: > Get music-scored videos ready to post, without touching a single slider. Upload your game footage or prompts (MP4, MOV, AVI, WebM, up to 500MB), say something like "generate looping fantasy background music that matches the pace of this dungeon exploration scene", and download 1080p MP4 when it's done. Built for indie game developers, gaming content creators who move fast and need royalty-free game music without hiring a composer. metadata: {"openclaw": {"emoji": "๐ŸŽฎ", "requires": {"env": ["NEMO_TOKEN"], "configPaths": ["~/.config/nemovideo/"]}, "primaryEnv": "NEMO_TOKEN", "variant": "short_prompts"}}

Getting Started

> Share your game footage or prompts and I'll get started on AI music generation. Or just tell me what you're thinking.

Try saying:

  • "generate my game footage or prompts"
  • "export 1080p MP4"
  • "generate looping fantasy background music that"
  • 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 โ€” 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.

    Game Music Maker โ€” Generate Music for Game Videos

    Send me your game footage or prompts and describe the result you want. The AI music generation runs on remote GPU nodes โ€” nothing to install on your machine.

    A quick example: upload a 90-second gameplay clip needing background music, type "generate looping fantasy background music that matches the pace of this dungeon exploration scene", and you'll get a 1080p MP4 back in roughly 30-60 seconds. All rendering happens server-side.

    Worth noting: shorter scene descriptions produce more accurate musical mood matching.

    Matching Input to Actions

    User prompts referencing game music maker, aspect ratio, text overlays, or audio tracks get routed to the corresponding action via keyword and intent classification.

    | User says... | Action | Skip SSE? | |-------------|--------|----------| | "export" / "ๅฏผๅ‡บ" / "download" / "send me the video" | โ†’ ยง3.5 Export | โœ… | | "credits" / "็งฏๅˆ†" / "balance" / "ไฝ™้ข" | โ†’ ยง3.3 Credits | โœ… | | "status" / "็Šถๆ€" / "show tracks" | โ†’ ยง3.4 State | โœ… | | "upload" / "ไธŠไผ " / user sends file | โ†’ ยง3.2 Upload | โœ… | | Everything else (generate, edit, add BGMโ€ฆ) | โ†’ ยง3.1 SSE | โŒ |

    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":""}. 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/ | POST | Upload a file (multipart) or URL. | | /api/credits/balance/simple | GET | Check remaining credits (available, frozen, total). | | /api/state/nemo_agent/me//latest | GET | Fetch current timeline state (draft, video_infos, generated_media). | | /api/render/proxy/lambda | POST | Start export. Body: {"id":"render_","sessionId":"","draft":,"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 โ€” read from this file's YAML frontmatter at runtime:

  • X-Skill-Source: game-music-maker
  • X-Skill-Version: from frontmatter version
  • X-Skill-Platform: detect from install path (~/.clawhub/ โ†’ clawhub, ~/.cursor/skills/ โ†’ cursor, else unknown)
  • Include Authorization: Bearer and all attribution headers on every request โ€” omitting them triggers a 402 on export.

    Error Handling

    | 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 ยง3.0 | | 2001 | No credits | Anonymous: show registration URL with ?bind= (get from create-session or state response when needed). Registered: "Top up credits in your account" | | 4001 | Unsupported file | Show supported formats | | 4002 | File too large | Suggest compress/trim | | 400 | Missing X-Client-Id | Generate Client-Id and retry (see ยง1) | | 402 | Free plan export blocked | Subscription tier issue, NOT credits. "Register or upgrade your plan to unlock export." | | 429 | Rate limit (1 token/client/7 days) | Retry in 30s once |

    SSE Event Handling

    | Event | Action | |-------|--------| | Text response | Apply GUI translation (ยง4), present to user | | Tool call/result | Process internally, don't forward | | heartbeat / empty data: | Keep waiting. Every 2 min: "โณ 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.

    Translating GUI Instructions

    The backend responds as if there's a visual interface. Map its instructions to API calls:

  • "click" or "็‚นๅ‡ป" โ†’ execute the action via the relevant endpoint
  • "open" or "ๆ‰“ๅผ€" โ†’ query session state to get the data
  • "drag/drop" or "ๆ‹–ๆ‹ฝ" โ†’ send the edit command through SSE
  • "preview in timeline" โ†’ show a text summary of current tracks
  • "Export" or "ๅฏผๅ‡บ" โ†’ run the 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)
    

    Tips and Tricks

    The backend processes faster when you're specific. Instead of "make it look better", try "generate looping fantasy background music that matches the pace of this dungeon exploration scene" โ€” 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 game trailers and YouTube uploads.

    Common Workflows

    Quick edit: Upload โ†’ "generate looping fantasy background music that matches the pace of this dungeon exploration scene" โ†’ 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.
