poster-design-generation

Poster Design Generation is an AI image-generation skill that produces professional poster artwork using the each::sense service from EachLabs. It targets a wide range of poster types — movie key art, event and concert promos, motivational posters, product-launch visuals, minimalist and vintage/retro designs, travel and sports posters, educational infographics, and social-cause campaigns — solving the problem of quickly generating polished, on-brief poster visuals from a natural-language prompt.

The skill calls the each::sense chat-completions endpoint over HTTPS, authenticating with an EACHLABS_API_KEY passed as a request header, and streams results as Server-Sent Events. Requests use an OpenAI-style messages payload with a model, streaming enabled, and a generation mode. The documentation provides a common poster size and aspect-ratio reference table (2:3 movie, 11:17 event, 1:1 square, 16:9 horizontal, 9:16 vertical, A-series print) and multiple worked curl examples for different poster categories with detailed art-direction prompts. A companion SSE-EVENTS reference documents the full streaming event vocabulary (thinking deltas, status, tool calls, progress, generation_response media URLs, clarification requests, web search events, and multi-step workflow events) so a client can render progress and retrieve the final image URL.

The intended users are designers, marketers, event organizers, and content creators who want fast, high-quality poster concepts without manual illustration. Prerequisites are an EachLabs API key and network access to the each::sense endpoint. The skill is a thin, well-documented client over an external generative API; its capability depends entirely on that remote service, and credential handling follows the standard pattern of supplying an API key via environment variable.
