I've been working on a LLM fiction writing workflow and associated tools. It's built on agentic coding tools with lots of structure, guidance, prompting, and critique. Almost all of the flow is on the filesystem and using a custom command-line tool, making it accessible to agentic programming tools. (No MCP though; it seems superfluous?)

I was fairly neutral about the tool for a while, but lately I've been going all-in on Claude Code, using things like rules and subagents.

It's also built to "rerender" the story, for instance rewriting it (slightly) for voice, translate it, or target different reading levels or background. I'm interested in translating stories for language learners in addition to simply translating into other native languages.

I'm also hoping to create some stories that stretch the medium. Perhaps CYOA (though I'm struggling with understanding what a CYOA is good at), though also other multi-perspective stories with reader autonomy in how to read through the story. LLMs make it easier to overproduce content, so you can give the reader flexibility without feeling regret that much of the content will be skipped, or rewrite passages for readers who jump into stories part way through.

Producing quality content is hard, and frankly kind of expensive, which is why I'm focused on finished products instead of interactive experiences. Though I do look forward to some future opportunity to take these rich characters that are grounded in full stories and find other things to do with them.
