Write code with Claude

Get complete insight into your codebase and accelerate exceptional software.

I'll investigate the auth error. Let me look at the relevant files.

Examining auth-related files...

* src/services/authService.js

* src/components/Login.jsx

* src/store/authSlice.js

Running the login flow...

Error detected: "401 Unauthorized: Token expired"

Root cause:

* Token refresh mechanism not handling expired tokens correctly

* Refresh token missing from request header

* Improper error handling for 401 responses

Updating authService.js with proper refresh logic...

Updating request interceptor for 401 handling...

Testing the fix...

* Login successful ✓

* Token refresh working ✓

* Proper redirection on expired tokens ✓

Authentication error fixed! The login flow now properly handles token expiration.

Scale coding impact, not overhead

Write, test, and debug complex software with Claude, analyze codebases with expert-level reasoning via GitHub integration, delegate development tasks through computer use, and fast-track smarter engineering decisions in a shared workspace.

Developers love Claude

“I taught a friend who has never written code in her life how to use Claude to build a simple app and deploy it on Cloudflare today. Watching someone realize that they can now build software is a great experience. Enable everyone to build anything.”

Logan Grasby, @LoganGrasby

“I introduced someone to Claude Code, Opus last night, and we were up til 4 am building a project. It was crazy! 20K lines of codes, audit logging, a full Prisma Database, complete architecture, and a complete roadmap with 4 phases for complete implementation.”

Teneika Askew, @teneikaask_you

“Just taught my fiancée how to use claude to write code that automates dumb tasks that have been making her work life miserable for months. She went from being downtrodden and skeptical to dancing around the room in about 15 minutes. END USER PROGRAMMING IS NOW.”

Kasey, @kaseyklimes

“Claude 4 Opus is exactly the future we were promised. I sit down, prompt a little bit, check to make sure the program is doing what i wanted. “8 hours” of work done with almost no labor or input from me. Now time to go get ice cream and watch Twitch until I get more tokens.”

@airkatakana

“I know this sounds cringe, but I literally have clammy hands and a racing heart because of how powerful Claude + Cursor is. Like I just made a whole new feature, frontend and backend, built on top of my own custom APIs without touching code, then I had it switch from a SwiftUI.”

Majd Taby, @jtaby

“Claude Code + Opus 4 is the best agentic coding tool in the world and it’s not close.”

Mckay Wrigley, @mckaywrigley

“Anthropic is leading the Industry with models - like Sonnet and Opus - and developer tools - like Claude Code.”

Jon Meyers, @jonmeyers_io

“With new Claude i officially feel like a fraud when i code, I’m the guy in the corner saying um nice job boss keep going.”

Integrate Claude’s powerful AI capabilities into your apps and deliver production-grade solutions faster.

You are an AI assistant specialized in classifying customer support tickets. Your task is to analyze the content of a given ticket and assign it to the most appropriate category from a predefined list. You will also provide reasoning for your classification decision.

First, let's review the available categories:

<category_list>
{{CATEGORY_LIST}}
</category_list>

Now, here is the content of the support ticket you need to classify:

<ticket_content>
{{TICKET_CONTENT}}
</ticket_content>

Please follow these steps to complete the task:
– Carefully read and analyze the ticket content.
– Consider how the content relates to each of the available categories.
– Choose the most appropriate category for the ticket.
– Provide a detailed explanation of your reasoning process.

Use the following structure for your response:
<classification_analysis>
In this section, break down your thought process:
– Quote the most relevant parts of the ticket content.
– List each category and note how it relates to the ticket content.
– For each category, provide arguments for and against classifying the ticket into that category.
– Rank the top 3 most likely categories.
</classification_analysis>

<classification>
<category>Your chosen category goes here</category>
<reasoning>A concise summary of your reasoning for choosing this category</reasoning>
</classification>

Remember to be thorough in your analysis and clear in your explanation. Your goal is to provide an accurate classification with well-supported reasoning.

“Early testing shows Claude Opus 4.6 delivering on the complex, multi-step coding work developers face every day—especially agentic workflows that demand planning and tool calling. This starts unlocking long horizon tasks at the frontier.”

Mario Rodriguez, Chief Product Officer, GitHub

“Claude Opus 4.6 is the new frontier on long-running tasks from our internal benchmarks and testing. It's also been highly effective at reviewing code.”

Michael Truell, Co-founder & CEO, Cursor

“Claude Opus 4.6 reasons through complex problems at a level we haven't seen before. It considers edge cases that other models miss and consistently lands on more elegant, well-considered solutions. We're particularly impressed with Opus 4.6 in Devin Review, where it's increased our bug catching rates.”

Scott Wu, CEO, Cognition

“Claude Opus 4.6 is a huge leap for agentic planning. It breaks complex tasks into independent subtasks, runs tools and subagents in parallel, and identifies blockers with real precision.”

Michele Catasta, President, Replit

“Claude Opus 4.6 scores 69% on Terminal Bench 2 in Droid, a clear jump from Opus 4.5. For autonomous software engineering, that's a meaningful step forward.”

Leo Tchourakov, Principal Engineer, Factory

“Claude Opus 4.6 autonomously closed 13 issues and assigned 12 issues to the right team members in a single day, managing a ~50-person organization across 6 repositories. It handled both product and organizational decisions while synthesizing context across multiple domains, and knew when to escalate to a human.”

Yusuke Kaji, General Manager, AI, Rakuten

“Claude Opus 4.6 just keeps working through problems without needing to be nudged. I ran it headlessly for much longer than any model we've used before. It's significantly more persistent and agentic.”

Nick Weatherburn, Head of AI Infrastructure & Agents, Palantir

“Both hands-on testing and evals show Claude Opus 4.6 is a meaningful improvement for design systems and large codebases, use cases that drive enormous enterprise value. It also one-shotted a fully functional physics engine, handling a large multi-scope task in a single pass.”

Eric Simons, CEO, Bolt

“Claude Opus 4.6 is an uplift in design quality. It works beautifully with our design systems and it's more autonomous, which is core to Lovable's values. People should be creating things that matter, not micromanaging AI.”

Fabian Hedin, Co-founder, Lovable

“Claude Opus 4.6 handled a multi-million-line codebase migration like a senior engineer. It planned upfront, adapted its strategy as it learned, and finished in half the time.”
