People have been impressed with the results of switching from Cursor to Claude Code, but when you've got bugs and feature requests flooding in from Slack, Sentry, and email with only a small team to handle them, things get overwhelming fast.

Claude Code helps, but it only goes so far when working in isolation. Here's how Cyrus integrating Linear with Claude Code helped us close 38 issues in the last three weeks with almost zero intervention. This is the complete guide to using Cyrus for automatic issue resolution between Linear and Claude Code.

A feature request comes in, we push it to Linear, and it moves to in progress instantly. Cyrus picks it up and starts working on the issue.

The demo that changed everything

Here's what happens when we assign an issue to Cyrus:

Watch Cyrus get to work. While Cyrus handles the issue, you can grab a coffee.

[One coffee break later...]

The work is complete. Cyrus has analyzed the issue, implemented a solution, and opened a pull request with detailed documentation. The final summary is thorough and the code quality is excellent.

Why this changes everything

Cyrus runs on your own infrastructure - whether that's your home computer, a DigitalOcean droplet, or anywhere you choose. With MCP servers, the possibilities are endless.

Cyrus brings together two powerful tools: Linear's issue tracking and Claude Code's AI development capabilities. But here's what makes it special - it's not just another automation tool. It's an agent that works like a developer on your team.

How Cyrus powers our development with Linear and Claude Code

While building Ceedar, we found a way to maintain high quality while moving fast. We've open-sourced this approach and also offer it as a hosted service called Cyrus. It's a Linear and Claude Code integration that works as an actual agent inside Linear - someone you can assign issues to just like any other team member.

The way that it works is it integrates with Linear's new Agents feature, which is a really neat framework for sharing what agents are working on inside of Linear Agent sessions.

The real power: bugs that fix themselves

Cyrus produces detailed summaries and opens pull requests for every completed task. This example is particularly interesting because the bug came directly from Sentry into Linear, and Cyrus automatically recognized it should use the debugging workflow.

Notice the message: "Entering debugger mode because of the bug label. I'll follow the debugger process."

We've built custom workflows where Cyrus connects directly to Sentry via MCP servers to gather issue details and additional context. The MCP ecosystem opens up endless integration possibilities.

Feature building on autopilot

Bug fixes are just the beginning. Cyrus also excels at feature development. When an issue has a feature label, Cyrus automatically switches to builder mode.

We've crafted specialized system prompts that make Cyrus work intuitively. It breaks down complex features into subtasks, provides concise summaries, and offers a streamlined interaction experience.

Cyrus: team collaboration that actually works with Linear and Claude Code

You can continue conversations with Cyrus, providing feedback and refinements until you get exactly what you need. Your entire team can collaborate with Cyrus, making it a true force multiplier.

We've also integrated powerful testing capabilities. Through MCP connections, Cyrus can control Playwright in a secure environment to navigate websites, run tests, and validate implementations automatically.

These are just a few examples of what's possible with Cyrus. The potential applications are limitless.

The numbers don't lie: 38 issues in 3 weeks

Let's talk real results. In the past three weeks, here's what happened:

• 38 issues closed (compared to our usual 15-20)
• 147 hours saved (average 3.9 hours per issue)
• 87% first-attempt success rate (only 5 issues needed human intervention)
• 4.2 hour average resolution time (down from 2-3 days)

But here's what really matters: our customers noticed. Response time to feature requests dropped from weeks to days. Bug fixes that used to sit in the backlog for months were resolved overnight.

How to set up Cyrus with Linear and Claude Code in 15 minutes

Here's the straightforward path to getting Cyrus running on your team with Linear and Claude Code:

Step 1: install Cyrus

# Install globally
npm install -g cyrus-ai

Step 2: connect Linear

Run cyrus now and it will ask you to authorize Linear.

Note: You'll need to either be running your own proxy server and Linear OAuth Application, or be on a paid plan (or at least free trial of one) to have it work.

Step 3: configure your workflows

The magic happens through labels. Just like we saw in the demo:

• bug label → Cyrus enters debugger mode
• feature label → Cyrus enters builder mode
• performance label → Cyrus optimizes your code

Edit your ~/.cyrus/config.json if you want to change the default labels:

{
  "repositories": [{
    "labelPrompts": {
      "debugger": ["Bug"],
      "builder": ["Feature", "Improvement"],
      "scoper": ["PRD"]
    }
  }]
}

Step 4: test it out

Create a test issue in Linear, assign it to Cyrus, and add a configured label (like "Bug" or "Feature") to watch the magic happen. Immediately, Cyrus picks it up and starts working.

Real examples from our sprint

Let me show you what kinds of issues Cyrus excels at with Linear and Claude Code:

Example 1: Sentry bug → fixed PR in 4 hours

The Issue: TypeError coming from production via Sentry integration What Happened:

• Sentry webhook created Linear issue automatically
• Cyrus saw the "bug" label and entered debugger mode
• Connected to Sentry API to get full stack trace
• Found the root cause (missing null check)
• Fixed it, added tests, created PR
• Total time: 4 hours 12 minutes

Example 2: customer feature request → shipped same day

The Issue: "Add CSV export to dashboard" What Happened:

• Customer request came through Slack
• We created Linear issue with "feature" label
• Cyrus analyzed existing export functionality
• Implemented CSV export following our patterns
• Added UI button, backend endpoint, tests
• Customer got the feature: Same day

Example 3: performance issue → 87% faster

The Issue: "Dashboard slow for users with 500+ projects" What Happened:

• Cyrus profiled the code
• Found N+1 query problem
• Implemented eager loading
• Added Redis caching
• Result: Load time dropped from 4.2s to 0.5s

What works best with Cyrus

Through 38 issues, we've learned what Cyrus absolutely crushes using Linear and Claude Code:

Perfect for:

• ✅ Bug fixes with clear error messages
• ✅ Adding API endpoints
• ✅ Database migrations
• ✅ Test coverage improvements
• ✅ Documentation updates
• ✅ Performance optimizations
• ✅ Component creation with clear specs

Good for:

• 👍 UI updates (when you have mockups)
• 👍 Third-party integrations
• 👍 Refactoring well-defined code
• 👍 Adding missing TypeScript types

Still needs you for:

• 🤔 Complex architectural decisions
• 🤔 Security-critical implementations
• 🤔 Ambiguous business logic
• 🤔 Design decisions

The questions everyone asks

"Is my code secure?"

Yes. Everything runs on your infrastructure. Your code never leaves your environment. Cyrus runs on your own computer, a DigitalOcean droplet, or anywhere you choose. Complete control.

"What if it makes mistakes?"

Every change goes through your normal PR review process. Nothing gets merged without human approval. Our 87% success rate means occasional tweaks are needed, but the time savings are massive.

"How much does it cost?"

Three options:

• Open Source (Free): Self-hosted with all core features
• Pro ($50/month): Managed Linear app, no setup required
• Enterprise (Custom): Dedicated infrastructure, SLA, priority support

All plans include a 7-day free trial. Credit card required.

"Can it work with our stack?"

Yes. Cyrus works with any language, framework, or tool. It learns from your codebase and follows your patterns. TypeScript, Python, Go, Ruby - doesn't matter.

"How long to see results?"

Most teams see their first automated PR within 15 minutes. By week 2, you're shipping 2-3x faster. By month 2, it's just how you work.

The bottom line

Three weeks ago, we were drowning in issues. Today, we ship faster than teams 20x our size.

Cyrus isn't just about automation - it's about giving your team superpowers. Every issue that gets auto-resolved is time you can spend on what matters: talking to customers, designing the future, building the hard stuff that only humans can build.

Ready to ship 20x faster?

P.S. While you've been reading this, teams using Cyrus have probably resolved 5-10 issues automatically. Every day you wait is another day of manual work. Start your free trial now →
