resize-image

What it does

Downloads an image (e.g., from Wikipedia), resizes it, and returns a base64 JPEG.

AgentPM manifest

See agent.json in this folder. It declares:

• "kind": "tool", "runtime": { "type": "node", "version": "20" }
• "entrypoint": { "command": "node", "args": ["dist/index.cjs"] }
• JSON Schema for inputs and outputs

Quirks

• Uses undici + Jimp. Keep-alive disabled; deterministic exit after writing JSON.
• Handles large outputs by chunking JSON to stdout to avoid pipe backpressure.

Entrypoint reads JSON from stdin and prints a single JSON object to stdout.
