Linear CLI

Why Linear CLI?

The economics of code have changed. A decade ago, a line of production code cost $15-50 to write. Today, AI coding assistants generate code for pennies. This explosion in code generation creates a new bottleneck: coordination.

Agentic coding works brilliantly for individual developers. But scaling it to teams—where multiple agents, human developers, and product managers collaborate—remains unsolved.

Linear CLI bridges this gap:

• For agentic coding: Agents read and update Linear issues as they work, maintaining shared state across your entire team
• For agentic product management: AI assistants can search, triage, and analyze your backlog alongside human PMs
• For hybrid teams: Human and AI contributors work from the same source of truth

Linear becomes the coordination layer—tracking what's planned, what's in progress, and what's done—while agents and humans focus on building.

---

A token-efficient command-line interface for Linear.

Why this tool? Human-readable identifiers ("TEST-123" not UUIDs), smart caching, and ASCII output—90% fewer tokens than alternatives.

Authentication

linear auth login

You'll be prompted to choose an authentication mode:

Personal Use - Authenticate as yourself

• Your actions appear under your Linear account
• For personal task management

Agent/App - Authenticate as an agent

• Agent appears as a separate entity in Linear
• Requires admin approval to install
• Agent can be @mentioned and assigned issues
• For automation, bots, and integrations

OAuth Setup

Personal Mode Setup

During login, you'll be prompted for:

1. OAuth callback port (default: 37412)

   • Press Enter to use default, or specify a custom port
   • The wizard shows you the callback URL to configure

2. Create an OAuth app in Linear:

   • Go to Linear → Settings → API → OAuth Applications → New
   • Set callback URL: http://localhost:YOUR_PORT/oauth-callback
   • Copy the Client ID and Secret

3. Enter credentials when prompted

Credentials (including port) are saved to ~/.config/linear/config.yaml.

Agent Mode Setup

For agent/automation use (bots, CI/CD, integrations):

1. Create an OAuth app in Linear:

   • Go to Linear → Settings → API → OAuth Applications → New
   • Name: linear-cli-agent (or your preferred name)
   • Callback URL: http://localhost:3000/oauth-callback
   • Actor: Application (not User)
   • Click "Create"

2. Save your credentials:

   • Client ID: Copy and save this (you'll need it for login)
   • Client Secret: Copy and save this immediately (shown only once)
   • Store these securely - you'll need them to authenticate

3. Authenticate:

   linear auth login
   # Select "Agent/App" mode
   # Enter port: 3000
   # Enter Client ID and Secret when prompted
   

4. Admin approval required:

   • After authentication, a Linear admin must approve the app installation
   • Go to Linear → Settings → Installed Applications
   • Approve the pending installation

Once approved, the agent can be @mentioned and assigned issues like any team member.
