Cortex

Autonomous agent system for long-running projects. You give it a mission with a success criterion, and it plans the work, hands focused pieces to subagents, keeps a structured log of progress in your repo, and checks the result against what you agreed — across days or weeks of unattended work.

Why Cortex?

Cortex is designed around three failure modes of long agent runs:

• Context rot — durable project state lives as plain files in your repo, not chat history that accumulates and decays.
• Execution drift — non-trivial work starts from a plan you approve, long tasks keep a live board of their state, plan, and decisions, and every completion claim points at its evidence.
• Context window limits — bounded pieces of work go to subagents that start with a fresh context and return only their result.

Features

• Subagents and team mode — bounded work goes to subagents with a clean context; with team mode on, a session can lead persistent worker sessions (Team Mode).
• Boards for long work — a long task keeps a live status page beside the conversation, showing its state, plan, what needs you, and the decisions taken (Boards).
• Structured project log — every project keeps mission, roadmap, status, experiments, knowledge, patterns, and decisions as plain files.
• Cron and interval scheduling — schedule Cortex to scan, digest, or sweep on a recurring basis.
• Editable skills and plugins — skills are plain SKILL.md files that Cortex and you can write, override, or revert, on disk or from Settings → Plugins (Skills & Plugins).
• One agent across your machines — connect any Mac, Windows, or Linux machine via cortex-client.
• Web, native app, chat, and terminal access — use the browser workbench, Linux/macOS/Windows desktop app, Android app, Slack, Feishu, or TUI against the same server. The workbench shows sessions, workers, boards, approvals, machines, and project memory side by side.

Ways to use Cortex

Interface	Best for	Guide
Browser workbench	Access from an existing browser without installing a client	Browser Access
Desktop app	Native Linux, macOS, or Windows workbench	Desktop and Android Apps
Android app	Mobile sessions, projects, and approvals	Desktop and Android Apps
Slack or Feishu	Chat-driven operation and notifications	Quickstart
TUI	Full-screen terminal operation	CLI Reference

Quickstart

The desktop app installs and starts a Cortex server on macOS, Linux, or Windows without a terminal. From a terminal:

npm install -g @cortex-agent/server
cortex init
cortex ui enable
cortex daemon

See Quickstart for detailed server and chat-platform setup. Once the server is running, open the workbench at http://127.0.0.1:3004 on the server, use Browser Access to reach it from elsewhere, or connect a native client as described in Desktop and Android Apps.
