AI image and video generation skill for Claude Code and other coding agents — Gemini, OpenAI and Kie AI behind one CLI and MCP server, with EU AI Act content marking.
mediagen — an image and video generation skill for coding agents
Give your agent image and video generation across Google Gemini, OpenAI and Kie AI — one skill, one install, no API to learn.
Say roughly what you want and let it decide the rest:
It wrote the prompt out in full, knew 21:9 rules OpenAI out, and read the path back from --json.
It marked in a second pass, after seeing where the subject ended up — and put the label on the flat roofline rather than over the loading bay.
Anything the CLI takes can be asked for in words — provider, model, aspect ratio, size, output name and directory, quality preset, video duration, an input image to edit, and whether to mark the result. Name any of them and the agent uses it as given; leave it out and it chooses, or falls back to what you configured.
That is the whole installation. Nothing else to set up — the skill runs the CLI through npx, which fetches it on first use and caches it afterwards.
An interactive wizard: pick providers, enter each key without it being echoed, verify each against the live API, choose a model per provider, and set a default. One key is enough to start.
- Generate images and video from a description, or edit media you already have - Choose the right provider for the task — the skill knows Gemini handles 21:9 and video, that OpenAI cannot do 16:9 at all, and that Kie aggregates around thirty third-party models - Take your instructions literally when you give them. Name a model, a ratio, a size or a filename and it is used as stated. mediagen models is there when you want to see what is available
