machinate

A lightweight CLI to plan work with coding agents. It reads and writes a .machi/ directory in your project, which holds four kinds of plain Markdown documents:

• plans: units of work with a goal and a status (draft / active / done)
• tasks: the concrete steps that make up a plan
• context: background documents an agent needs while working
• docs: project-level reference material shared across plans

One state file (.machi/machinate.toml) records project settings and the current plan. There is no server or database: documents stay editable by hand, and search (machi search) runs locally through Tantivy.

Install

uv tool install machinate   # or: pipx install machinate

Requires Python 3.14.

Usage

machi init                         # create .machi/ in this project
machi plan add auth                # create a plan
machi plan select auth             # make it the current plan
machi task add 01-login 02-logout  # create two tasks on the current plan
machi task list                    # show the tasks
machi context add spec             # add a plan context document
machi doc add architecture         # add a project-level doc
machi plan show auth               # show the full plan

That leaves this tree on disk:

.machi/
├── machinate.toml             project name and the selected plan
├── docs/
│   └── architecture.md        machi doc add architecture
└── plans/
    └── auth/
        ├── plan.md            machi plan add auth
        ├── tasks/
        │   ├── 01-login.md    machi task add 01-login 02-logout
        │   └── 02-logout.md
        └── context/
            └── spec.md        machi context add spec

Every document is Markdown with YAML frontmatter, so it stays diffable and editable by hand. machi plan select only rewrites machinate.toml; each add command creates one file, and task and context names may contain subdirectories to nest documents.

machi search searches every plan and all docs through Tantivy, with fuzzy and prefix matching on by default:

• machi search "login OR logout" searches all plans and docs.
• machi search '"bearer token"' -p auth matches a phrase in one plan.
• machi search -p auth --glob 'tasks/**/*.md' filters by path, ANDed with the query.

Plan commands take the plan name positionally (machi plan show auth). -p PLAN narrows tasks, context, or search to one plan; -P PROJECT_DIR a project, --format json for agents.

Use with coding agents

Add the agent instructions to your project, so agents know how to use machinate:

machi instructions >> AGENTS.md

When AI_AGENT (set by Claude Code and other agents that follow that convention) or MACHI_AI_AGENT is set, machinate runs in agent mode: plan-scoped commands need an explicit plan, plan select is disabled so parallel sessions can't retarget each other, and output defaults to JSON. Errors carry a machine-readable code, and machi schema <command> prints the JSON shape of each result.
