Claude Code SDK Performance
Users are discussing the latency and battery usage of Claude Code SDK, as well as experiences hosting it in ECS containers and Modal sandboxes.
Appreciate it today we’re built on the claude code SDK, so it’s the same latency as local. on battery: we haven’t seen any noticeable additional drain so far since the agent loop runs on computer or cloud sandbox and mobile is just streaming events + approvals over
Curious what specific issues you’re having with agent sdk. Hosting in ecs containers or modal sandboxes is solid and DX tracks closely to local Claude code setup in our world.

Claude Code Adoption and Usage
The tweets discuss Claude Code's current revenue reliance on API customers, access credential issues, marketing applications showcasing efficiency gains, and new security review features.
TIL Cursor, Cognition, Microsoft, Canva (API customers) are still the vast majority of Anthropic's revenue. I wonder if Claude Code overtakes that one day.
Again, @AnthropicAI? Keep pushing people away from your platform. Any other opencode/oh-my-opencoders getting this today? "This credential is only authorized for use with Claude Code and cannot be used for other API requests."

A new paper just dropped: How Anthropic's Marketing team cut ad creation time from 30 minutes to 30 seconds with Claude Code
Claude Code's Agent Capabilities
People are discussing Claude Code's agent capabilities, particularly its parallel agents, persistent task graphs, and ability to manage complex coding tasks with features like state management and filesystem persistence.
AI used to help you code. Now it’s learning to manage the work. Claude Code’s 𝐚𝐠𝐞𝐧𝐭 𝐬𝐰𝐚𝐫𝐦 concept: • parallel agents • persistent task graphs • less micromanagement • faster shipping What would you delegate first if AI could orchestrate tasks end-to-end?
Claude Code's Tasks update: persistent state management for agents. Session crashes don't erase your build plan. Trade-off: manual coordination. DAGs + filesystem persistence + shared state via env variables. https://t.co/lyLCxHotxL https://t.co/100xVtOu2C
Claude Code for Prototyping
People are discussing using Claude Code for quickly creating prototypes and initial versions of software, with the understanding that real engineers are still needed for production-ready applications.
I mean I am sure you’d get sales if you advertised on TikToks to non programmers but everyone here knows this is just an MCP and you can literally ask Claude code to make it for you or get the open source one from GitHub
I'm sharing them in case they're useful to anyone — but honestly I think you would be better served by asking Claude Code or Claude Cowork to build you you something like these yourself, to your own specifications. That'll teach you about the model's capabilities and limitations
nope, but claude code will make one for you if you ask it nicely the app itself is live though, I'll not advertise it here but can be found from my profile
non-engineer ships to 10M yen with claude code then says i need real engineers now. most honest take on ai coding. the prototype is free. the production is not.
From your logic people should only use for coding Gemini 3/opus 4.5 thinking with better explanation etc , and not use a TOOL like Claude Code , it’s the same here , this feature is a TOOL built on top of existing models

People are discussing Claude Code's impact on developer workflows, including rapid code generation, system design, and potential to automate code management tasks.
Junior here, I still write code outside of work. Closing tickets on the job? Claude Code. Trying to learn outside the job? Writing code line-by-line and using AI to learn and go deeper.
Current tech stack: One senior dev, three junior devs, and a Claude Code instance that just rebuilt our entire year of work in an hour while we were still arguing about which coffee to order
@turingou multiple claude code instances on different branches creating PRs in parallel. we went from ai writes code to ai manages a dev team in about 3 months.
I told Claude Code it was our new Performance Engineering Lead and gave it its own workspace in @SubspaceHQ Gave it complete agency to design and build whatever is needed to help us become the most performance desktop app in the industry. Had it start with research, then
Claude code convinced to write tests for first time in my life. And y'all think we don't have ASI

People are discussing how Claude Code can automate marketing tasks like ad creation and SEO optimization, ultimately increasing productivity and allowing users to focus on higher-level strategic work.
if Claude Code isn't managing your Adwords campaigns with direct access via API and expert ad management & copywriting skills what are you even doing
If you're a startup founder publishing content, you should 100% have Claude Code run an SEO check on your website. You don't need any fancy skills, just a few MCPs: Ahrefs - http://docs.ahrefs.com/docs/mcp Google Search Console - [Links: https://t.co/bCtlFe9E6M]
Nailed it. AdWords requires a PhD to for a human to navigate. Claude Code knows its way around like a kindergartener in a candy shop
using claude code feels like unlocking a new gear people say AI makes devs lazy but that's backwards i'm doing MORE work, just different work now i'm spending that time on what actually matters: - reviewing code quality - thinking through architecture - marketing that's the

Rapid Claude Code Development
People are expressing excitement about Claude Code's speed and utility in various applications, from building landing pages and entire applications to onboarding new projects by explaining unfamiliar codebases.
Me with @IdeaKitchenAI. Last week I published the best way for non-coders to get started with Claude Code. This week, I’m sharing the best useful examples I’ve come across (not just Claude Code). I also really love the tweets that @alexhillman and @zarazhangrui share.
Maaaaaan alive I made this basic B2B landing in 15 mins with Claude code This stuff is actually unbelievable
Twitter is just free education at this point Every day I see some new Claude Code implementation that completely changes my work And then I wake up and do it again tomorrow
@T_Zahil Claude code for DevOps engineers https://t.co/PYZeIk0jbn
100% of http://onlyrecipes.app was built in the last month with Claude Code [Links: https://t.co/bCgBhFLpAM]

People are discussing Claude Code's impact on software development, highlighting its productivity gains, ease of integration with platforms like Slack, and potential for automation and enhanced workflows.
A month ago, I launched GSD. 8.5k+ GitHub stars later, it's become the #1 Claude Code framework for vibe coding successfully. The problem was simple: Claude is brilliant, but without structure it drifts. Context rots. Sessions become ping-pong hell. Half-baked snippets instead
Did you know Claude is in Slack? Just @.claude in any channel and ask it to review a PR, explain an error, or implement a feature. Claude Code on the web picks it up and gets to work. Ship from your conversations.
Claude Code can build software features in days that used to take weeks with developers. I've been using it for my SaaS and the workflow is insane. Here's what I learned: - How to plan software without hiring developers - The exact workflow to go from idea → shipped
I strongly recommend the Claude Code + Codex combo as a reviewer for your changes. I’m itching to build a tool to automate this.
Since installing Claude Code on January 11, I have worked 16 hours days, everyday, taking a break only on Sundays to play with my kids. It is so exciting that I cannot stop working. What I have achieved in under 3 weeks would have taken me over a year pre-Claude.
Claude Code Applications
People are exploring various applications of Claude Code, including trading bots, personal automation, event-driven cloud tasks, and social media management, with a focus on efficiency and ease of use.
Claude code can not automate your trading Unless you approach it this way It’s really the only way to use Claude to build trading bots You may wanna bm this if you actually wanna have Claude code bots for you
i use claude code over imessage. its like clawdbot but way simpler. i'm texting with claude code, running on my server with all my context. shipping PRs while i wait to board my plane btw - you can bring your claude max subscription. coming to @zocomputer later today
Cool idea: use Claude Code to help open models write CUDA kernels (for eg) by turning CC traces into Skills. They made a library out of it
1Code Automation is Claude Code, but event driven. New PR? New Linear task? Claude runs automatically in the cloud, completes the task end to end and sends you the output. No babysitting. No local setup. Just results. https://t.co/8qvxKZJRqY
Use case Claude Code (Linkedin/Gmail/Twitter) If AI is going to replace us, I might as well do it myself, willingly and knowingly. I run a solo activity on LinkedIn and I get a ton of DMs. It’s cool, but it’s time-consuming and takes up quite a bit of time. Having to pay
Claude Code Limitations
People are discussing the perceived decline in Claude Code's performance and information retention compared to Codex, expressing frustration and advocating for tolerance.
it's amazing how stupid claude code gets the longer the conversation drags on
claude code has been sloppedmax and i wont be gaslit any longer by the nerds
codex has significantly better compaction. claude code just summarizes the conversation and loses a lot of information.
do you prefer codex over claude code in general?
it kinda makes sense. the only people spending hours and hours on claude code are people who either don't have any pressure to actually ship anything (unemployed) or are nerds enough to chase the diminishing returns of "perfect" software, now that they can.
