CLATIUM/CLATIUM CODE

CLATIUM CODE

CLATIUM CODE is a terminal-based AI coding agent written in Rust, with an embeddable core and fully replayable sessions.

Project	CLATIUM CODE
Status	In design (design phase as of 2 November 2026)
Category	Developer tool / AI
Language	Rust
Platform	Windows (primary)
Code written	None
Repository	None public
Download	No download

Overview

• CLATIUM CODE is an AI coding harness for the terminal: you describe a task, a language model reads and edits files and runs commands on your machine, and every action is recorded in a session log you can rewind, fork or replay.
• It is written in Rust and split into a reusable core library and a terminal interface, so the agent loop can be embedded in other applications.

Note: CLATIUM CODE is in the design phase. No code has been written yet. The only artefact is one internal design document. Everything below describes what is planned.

Planned structure

Part	Planned name
Folder and repository	clatium-code
Binary	clatium-code
Core crate	clatium-code-core: agent loop, model clients, tools, session log
Terminal interface crate	clatium-code-tui

Planned for v1

• Talks to a language model and streams its responses.
• Reads, searches, creates and edits files.
• Runs shell commands (PowerShell on Windows) with streamed output.
• Asks permission before changing files or running commands, with configurable rules and modes: default, accept-edits, read-only plan and bypass.
• Keeps a visible task plan.
• Records every step to a log that can be resumed, rewound or replayed without contacting a model.
• Restores files as well as the conversation when rewinding.

Planned model providers

• Ollama Cloud (API key)
• xAI Grok (OAuth login)

Planned technical design

• Sessions: append-only event logs. Replaying one reproduces it exactly, which allows rewind, branching and offline tests.
• File checkpoints: content-addressed.
• Headless core: the core has no terminal dependency and can run headless.
• Windows first: CRLF line endings, long paths, reserved filenames and PowerShell quoting.
• Privacy: no telemetry. The only outbound traffic is the configured model requests.

What it is not

• Not a fork of Claude Code, OpenCode or any other agent.
• Not a GUI, editor extension, IDE plugin, daemon or hosted service.
• Not related to Minecraft, Minecraft modding or Horizon.
• No plugin marketplace, cloud sync or accounts.

Roadmap

The roadmap has no dates.

1. v1: terminal agent with chat, file read, search and edit, shell, permissions, hooks, a visible plan, a session log with rewind, fork and replay, and an evaluation suite.
2. v1.5: on-demand skill packs, custom slash commands, subagents, an MCP client, image input and background commands.
3. v2: ConPTY, sandboxed command execution, finer-grained diff approval, per-role model routing and session search.

Known limitations

• It is not usable today.
• There is no public repository, release or download.
• No availability date has been set.
