# Send Nano Banana Pro OpenRouter to your agent Hand the extracted package to your coding agent with a concrete install brief instead of figuring it out manually. ## Fast path - Download the package from Yavira. - Extract it into a folder your agent can access. - Paste one of the prompts below and point your agent at the extracted folder. ## Suggested prompts ### New install ```text I downloaded a skill package from Yavira. Read SKILL.md from the extracted folder and install it by following the included instructions. Tell me what you changed and call out any manual steps you could not complete. ``` ### Upgrade existing ```text I downloaded an updated skill package from Yavira. Read SKILL.md from the extracted folder, compare it with my current installation, and upgrade it while preserving any custom configuration unless the package docs explicitly say otherwise. Summarize what changed and any follow-up checks I should run. ``` ## Machine-readable fields ```json { "schemaVersion": "1.0", "item": { "slug": "nano-banana-pro-openrouter", "name": "Nano Banana Pro OpenRouter", "source": "tencent", "type": "skill", "category": "内容创作", "sourceUrl": "https://clawhub.ai/DuffyCoder/nano-banana-pro-openrouter", "canonicalUrl": "https://clawhub.ai/DuffyCoder/nano-banana-pro-openrouter", "targetPlatform": "OpenClaw" }, "install": { "downloadUrl": "/downloads/nano-banana-pro-openrouter", "sourceDownloadUrl": "https://wry-manatee-359.convex.site/api/v1/download?slug=nano-banana-pro-openrouter", "sourcePlatform": "tencent", "targetPlatform": "OpenClaw", "packageFormat": "ZIP package", "primaryDoc": "SKILL.md", "includedAssets": [ "SKILL.md", "scripts/generate_image.sh" ], "downloadMode": "redirect", "sourceHealth": { "source": "tencent", "slug": "nano-banana-pro-openrouter", "status": "healthy", "reason": "direct_download_ok", "recommendedAction": "download", "checkedAt": "2026-04-30T06:42:58.807Z", "expiresAt": "2026-05-07T06:42:58.807Z", "httpStatus": 200, "finalUrl": "https://wry-manatee-359.convex.site/api/v1/download?slug=nano-banana-pro-openrouter", "contentType": "application/zip", "probeMethod": "head", "details": { "probeUrl": "https://wry-manatee-359.convex.site/api/v1/download?slug=nano-banana-pro-openrouter", "contentDisposition": "attachment; filename=\"nano-banana-pro-openrouter-1.0.1.zip\"", "redirectLocation": null, "bodySnippet": null, "slug": "nano-banana-pro-openrouter" }, "scope": "item", "summary": "Item download looks usable.", "detail": "Yavira can redirect you to the upstream package for this item.", "primaryActionLabel": "Download for OpenClaw", "primaryActionHref": "/downloads/nano-banana-pro-openrouter" }, "validation": { "installChecklist": [ "Use the Yavira download entry.", "Review SKILL.md after the package is downloaded.", "Confirm the extracted package contains the expected setup assets." ], "postInstallChecks": [ "Confirm the extracted package includes the expected docs or setup files.", "Validate the skill or prompts are available in your target agent workspace.", "Capture any manual follow-up steps the agent could not complete." ] } }, "links": { "detailUrl": "https://openagent3.xyz/skills/nano-banana-pro-openrouter", "downloadUrl": "https://openagent3.xyz/downloads/nano-banana-pro-openrouter", "agentUrl": "https://openagent3.xyz/skills/nano-banana-pro-openrouter/agent", "manifestUrl": "https://openagent3.xyz/skills/nano-banana-pro-openrouter/agent.json", "briefUrl": "https://openagent3.xyz/skills/nano-banana-pro-openrouter/agent.md" } } ``` ## Documentation ### Nano Banana Pro Image Generation Generate new images using OpenRouter's Nano Banana Pro (Gemini 3 Pro Image Preview). ### Usage Run the script using an absolute path (do NOT cd to the skill directory first): Generate new image: sh ~/.openclaw/workspace/skills/nano-banana-pro-openrouter/scripts/generate_image.sh --prompt "your image description" [--filename "output-name.png" | --filename auto] [--resolution 1K|2K|4K] [--api-key KEY] Note: the shell version currently supports generation only (no input image editing). Important: Images are always saved under ~/.openclaw/workspace/outputs/nano-banana-pro-openrouter If --filename contains a path, only the basename is used ### Default Workflow (draft -> iterate -> final) Goal: fast iteration without burning time on 4K until the prompt is correct. Draft (1K): quick feedback loop sh ~/.openclaw/workspace/skills/nano-banana-pro-openrouter/scripts/generate_image.sh --prompt "" --filename auto --resolution 1K Iterate: adjust prompt in small diffs; keep filename new per run Final (4K): only when prompt is locked sh ~/.openclaw/workspace/skills/nano-banana-pro-openrouter/scripts/generate_image.sh --prompt "" --filename auto --resolution 4K ### Resolution Options The Gemini 3 Pro Image API supports three resolutions (uppercase K required): 1K (default) - ~1024px resolution 2K - ~2048px resolution 4K - ~4096px resolution Map user requests to API parameters: No mention of resolution -> 1K "low resolution", "1080", "1080p", "1K" -> 1K "2K", "2048", "normal", "medium resolution" -> 2K "high resolution", "high-res", "hi-res", "4K", "ultra" -> 4K ### API Key and Base URL The script checks for the API key in this order: --api-key argument (use if user provided a key in chat) OPENROUTER_API_KEY environment variable The API base URL must be set via OPENROUTER_BASE_URL. Use the full chat completions endpoint (for OpenRouter: https://openrouter.ai/api/v1/chat/completions). The script also loads .env files automatically (if present): Current working directory .env Skill directory .env Important: If a .env file exists, do not ask the user for the key up front. Just run the script and only ask if it errors with "No API key provided." ### OpenClaw Chat Execution Rules OpenClaw does NOT auto-source the skill .env file If ~/.openclaw/workspace/skills/nano-banana-pro-openrouter/.env exists: Use the read tool to read .env Extract OPENROUTER_API_KEY and OPENROUTER_BASE_URL Always pass the key via --api-key when running the script Only ask the user if .env is missing or the key cannot be read If the user asks for a timestamped filename, prefer --filename auto (do not handwrite dates) If neither is available, the script exits with an error message. ### Preflight and Common Failures (fast fixes) Preflight: command -v sh (must exist) command -v curl (must exist) command -v base64 (must exist) Common failures: Error: No API key provided. -> read .env and retry with --api-key; if still failing, ask the user to set OPENROUTER_API_KEY Error: No API base URL provided. -> ensure OPENROUTER_BASE_URL is set to a full chat completions endpoint Error loading input image: -> wrong path or unreadable file; verify --input-image points to a real image "quota/permission/403" style API errors -> wrong key, no access, or quota exceeded; try a different key/account ### Filename Generation Generate filenames with the pattern: yyyy-mm-dd-hh-mm-ss-name.png Format: {timestamp}-{descriptive-name}.png Timestamp: Current date/time in format yyyy-mm-dd-hh-mm-ss (24-hour format) Name: Descriptive lowercase text with hyphens Keep the descriptive part concise (1-5 words typically) Use context from the user's prompt or conversation If unclear, use image Examples: Prompt "A serene Japanese garden" -> 2025-11-23-14-23-05-japanese-garden.png Prompt "sunset over mountains" -> 2025-11-23-15-30-12-sunset-mountains.png Prompt "create an image of a robot" -> 2025-11-23-16-45-33-robot.png Unclear context -> 2025-11-23-17-12-48-image.png Tip: To avoid incorrect timestamps, pass --filename auto and let the script generate the filename using the system clock. ### Image Editing (Not Supported in Shell Version) The shell script only supports generating new images. Editing an input image is not available in this version. ### Prompt Handling For generation: pass the user's image description as-is to --prompt. Only rework if clearly insufficient. ### Prompt Templates (high hit-rate) Use templates when the user is vague or when edits must be precise. Generation template: "Create an image of: . Style:
