Demiurge

demi is a terminal-native project lifecycle companion for developers who maintain many projects at once.

It is not a project manager — there are no tasks, boards, or tickets. It does not replace your editor, your shell, or git. Your day-to-day work stays exactly as it is. demi sits around that work, at the moments between projects, and makes the edges smarter: deciding what to build, setting it up, keeping it tidy, tearing it down cleanly, and remembering what you've done.

Local-only. No accounts, no cloud, no sync required.

Install

demi currently runs on macOS — both Apple Silicon and Intel.

Install with Homebrew:

brew install wroog-com/tap/demi

Or build from source with Go:

go install github.com/wroog-com/demiurge/cmd/demi@latest

Why it exists

If you keep a lot of projects going, the hard parts usually aren't in the code — they're around it:

• Starting a new project means the same setup ritual every time.
• Old experiments pile up, half-configured, and you're never sure what's safe to delete.
• When you do delete one, you're never sure you got everything — the repo, the local files, the bits of config scattered around.
• You have an idea and can't remember whether you already tried something like it, or you do remember you did but have no idea where to find it.

demi exists to hold that context for you. Because it knows about all your projects, it can help at each stage instead of leaving you to remember it all.

The lifecycle

demi thinks about a project as something that moves through stages. Between the stages, you're just working — editor, terminal, git, as usual. At the stages, demi helps.

1. Conceive — Before you start, ask demi whether an idea is actually new. Because it knows your whole history, it can tell you "you already have two projects that look like this" and give you the context to decide.
2. Create — Register the project so demi starts tracking it. This is lightweight: it adds the project to the list it maintains and asks a few questions to capture what it is. Nothing external happens yet.
3. Provision — When you're ready, have demi wire up the real-world pieces: create the hosted repository, apply a .gitignore from your rules, drop in the files and tooling you want every project to start with.
4. Maintain — Reset a project that's gone sideways, spin up a clean "v2", or re-apply your standard setup as your conventions evolve.
5. Retire — When you're done, demi cleans up after itself. Because it tracked what it set up, it can undo exactly that — leaving no trail — without guessing.
6. Remember — On the way out, demi can keep what it learned about the project, so the next time you conceive something similar it can remind you.

These stages are a way of thinking about the lifecycle, not a fixed checklist. They are non-exhaustive and will adapt as demi grows — expect them to be refined, split, or added to over time.

The AI-assisted parts of this (the "is this new?" reasoning, opinions about your projects) are a direction the tool is built toward, not all present yet.

Principles

• Companion, not manager. demi assists a normal workflow; it never becomes the workflow.
• demi owns only what demi created. It tracks your projects and the setup it performed on your behalf. It does not take ownership of your code — the filesystem and version control (and many other systems) already do that.
• Reversible by design. Anything demi sets up, demi can cleanly take back down. That promise is what makes it safe to let it do setup work at all.
• Local-first. Everything works on one machine with no external services. Any integration (code hosting, AI, and so on) is something you opt into.
• Accumulated context is the point. The value grows as demi learns more about your projects over time.

Stability

demi is pre-1.0 and under active development. Anything you might depend on — commands, flags, environment variables, and stored state — may change without a deprecation period until 1.0.

For contributors

• docs/vision.md — the product model and the reasoning behind it, written for people building demi.
• AGENTS.md — the working agreement: issue workflow, branching, releases. (CLAUDE.md is a thin @AGENTS.md import so tools expecting that filename still load it.)

Current focus and progress live in the repository's issues and milestones, not in this file.
