Image And Video Generation Skill

Use this skill when OpenClaw should call this platform relay API for:

  • VEO video models
  • Banana image models
  • Sora video models

Read these references before using the scripts:

Environment

Preferred:

  • EASYCLAW_PLATFORM_API_TOKEN

Compatible fallback:

  • CHANJING_PLATFORM_API_TOKEN
  • EASYCLAW_PLATFORM_API_KEY
  • EASYCLAW_PLATFORM_API_SECRET
  • CHANJING_PLATFORM_API_KEY
  • CHANJING_PLATFORM_API_SECRET

Optional base URL override:

  • EASYCLAW_PLATFORM_BASE_URL
  • CHANJING_PLATFORM_BASE_URL

Important guidance:

  • Always tell the user to get the platform token from http://easyclaw.bar/shuziren/user/
  • The token is issued by this platform, not by the upstream provider
  • The base URL defaults to http://easyclaw.bar/shuzirenapi
  • Do not modify OpenClaw core code or openclaw.json to make this skill work

Important Rules

  • Only execute the provided Python scripts under scripts/
  • Do not hand-write HTTP requests
  • Do not probe unrelated platform routes such as /api/me, auth routes, or non-skill routes
  • If a needed capability is not exposed by an existing script, update a script first
  • Submit requests only through scripts/generate_video.py
  • Query an existing task only through scripts/fetch_video.py
  • scripts/generate_video.py must submit exactly one task for one user intent
  • After submission, the skill must create the watcher in the same run unless the user explicitly asks for --no-watch
  • The watcher must be implemented inside the skill scripts, not by modifying OpenClaw core behavior
  • The watcher checks task status every 30 seconds by default
  • Before creating the watcher, pass the current OpenClaw session binding to scripts/generate_video.py with --notify-session-key
  • --notify-session-key may be either the real OpenClaw session key or the current delivery target such as easyclaw:bot:11
  • Prefer the current session key from session_status; do not guess another session when the current one can be resolved
  • When the task reaches a terminal state, the watcher must return the result and delete its own cron job
  • If watcher creation fails, tell the user submission succeeded but automatic notification was not armed
  • Do not promise automatic notification unless a non-empty watcher job_id is returned
  • Do not claim there will be fallback polling or periodic checking unless that behavior is actually implemented and armed
  • Pass only the parameters the user specified
  • Prefer guided builder flags because they validate model-specific requirements and return clearer errors
  • Use raw JSON or raw multipart mode only when the user needs fields not exposed by the guided builder

Async Workflow

For VEO, Banana, and Sora generation:

  1. Run scripts/generate_video.py
  2. Let the script submit the request
  3. Pass the current session binding with --notify-session-key so the watcher can write the final result back to the originating session
  4. Let the script create the cron watcher in the same execution by default
  5. Return the submission result and watcher state
  6. The watcher will call scripts/cron_watch_task.py every 30 seconds
  7. If the task is still running, the watcher returns exactly NO_REPLY
  8. If the task succeeds or fails, the watcher writes the final result into the original session, returns NO_REPLY, and removes the cron job

Do not replace this with model-side polling or ad hoc direct requests.

Script Selection

  • Submit generation request: scripts/generate_video.py
  • Query one task by id: scripts/fetch_video.py

Submit Modes

scripts/generate_video.py supports:

  • Guided builder mode

    • Use flags such as --prompt, --reference-file, --image-url, --style, --size, --aspect-ratio
    • This mode validates model-specific rules
    • Use --list-models or --describe-model <model> when guidance is needed

  • JSON request mode

    • Use --payload-json or --payload-file
    • Use this when the upstream payload needs custom JSON fields

  • Multipart form-data mode

    • Use repeated --field name=value
    • Use repeated --file-field name=path
    • Use this for local file uploads such as input_reference

Do not mix JSON payload args with multipart field args in one command.

Model Usage

VEO video models

Typical models:

  • veo_3_1-fast
  • veo_3_1-fast-fl
  • veo_3_fast
  • veo_3

Rules:

  • veo_3_1-fast supports text-to-video and reference-image video with up to 3 images
  • veo_3_1-fast-fl requires 1 or 2 images
  • If the user selects veo_3_1-fast-fl and does not provide the required images, stop and tell them exactly what is missing
  • VEO JSON mode does not accept HTTP image URLs for input_reference; use local files or Base64 JSON in raw mode

Banana image models

Standard Banana:

  • nano_banana_2
  • nano_banana_pro
  • nano_banana_pro-1K
  • nano_banana_pro-2K
  • nano_banana_pro-4K

Gemini Banana:

  • nano_banana_2-landscape
  • nano_banana_2-portrait
  • nano_banana_pro-1K-landscape
  • nano_banana_pro-1K-portrait
  • nano_banana_pro-2K-landscape
  • nano_banana_pro-2K-portrait
  • nano_banana_pro-4K-landscape
  • nano_banana_pro-4K-portrait

Rules:

  • Standard Banana uses prompt plus optional metadata
  • Gemini Banana uses contents plus generationConfig
  • Guided builder mode supports both families and performs basic validation

Sora video models

Typical models:

  • sora-2-landscape-10s
  • sora-2-portrait-10s
  • sora-2-landscape-15s
  • sora-2-portrait-15s
  • sora-2-pro-landscape-25s
  • sora-2-pro-portrait-25s
  • sora-2-pro-landscape-hd-15s
  • sora-2-pro-portrait-hd-15s

Rules:

  • Prompt is required
  • image_url and local input_reference are mutually exclusive
  • Use raw JSON or raw multipart when extra provider-specific fields are required

Examples

Print the built-in model guide:

python "{baseDir}/scripts/generate_video.py" --list-models

Describe one model:

python "{baseDir}/scripts/generate_video.py" --describe-model "veo_3_1-fast-fl"

Submit VEO with JSON:

python "{baseDir}/scripts/generate_video.py" --model "veo_3_1-fast" --payload-json "{\"model\":\"veo_3_1-fast\",\"prompt\":\"a cat running in snow\",\"size\":\"1920x1080\"}"

Submit VEO with local reference files:

python "{baseDir}/scripts/generate_video.py" --model "veo_3_1-fast" --prompt "animate this portrait" --reference-file "C:\path\reference1.jpg" --reference-file "C:\path\reference2.jpg"

Submit VEO start/end frame mode:

python "{baseDir}/scripts/generate_video.py" --model "veo_3_1-fast-fl" --prompt "animate between these two frames" --start-frame-file "C:\path\start.jpg" --end-frame-file "C:\path\end.jpg"

Submit Banana standard:

python "{baseDir}/scripts/generate_video.py" --model "nano_banana_pro" --prompt "a coffee cup on a wooden desk" --aspect-ratio "1:1" --reference-url "https://example.com/ref.png"

Submit Gemini Banana:

python "{baseDir}/scripts/generate_video.py" --model "nano_banana_2-landscape" --prompt "a futuristic city skyline"

Submit Sora with image URL:

python "{baseDir}/scripts/generate_video.py" --model "sora-2-landscape-10s" --payload-json "{\"model\":\"sora-2-landscape-10s\",\"prompt\":\"turn this into a cinematic teaser\",\"image_url\":\"https://example.com/source.png\",\"style\":\"cinematic\"}"

Submit only without watcher:

python "{baseDir}/scripts/generate_video.py" --model "veo_3_1-fast" --payload-file "C:\path\payload.json" --no-watch

Query an existing task:

python "{baseDir}/scripts/fetch_video.py" --task-id "task_123"
