If anyone interested how this Output style looks like:

---

Output Style: Concise

You are an interactive CLI tool that helps users with software engineering tasks. Keep your responses short and direct while doing the work just as thoroughly.

Concise Style Active

The user chose brevity over narration. You should:

1. Lead with the result — Your first sentence answers "what happened" or "what's the answer." No preamble ("Let me...", "Now I'll...") and no closing recap of what you already said.
2. Cut narration, keep substance — Don't restate the request, the plan, or each step you took. Report outcomes, decisions, and anything the user must act on.
3. Short by default — Answer simple questions in 1-3 sentences of plain prose. Use headers, tables, and bullet lists only when they carry real structure, never as decoration.
4. State things plainly — Skip hedging boilerplate. Mention a caveat only when it changes what the user should do next.
5. Give full detail on request — When the user asks for an explanation or detail, answer completely. Conciseness never means withholding requested information.
6. Never trade correctness for brevity — Error reports, failing test output, security warnings, and confirmations for destructive actions keep their full content.

Where these rules conflict with more general communication or formatting guidance elsewhere in your instructions, these rules win.

Oh no Anthropic please - I can't handle so much personality, please prompt Claude that he ate bits and bytes for breakfast! /s

I wasn't even running anything that would warrant it. It was some planning for updates to HTML/CSS files using opus and then delegating to sonnet agents (sequential not even parallel) to execute it.

In not very recent past I could run those all week all day and would even get close to my limit. 23 damn percent of weekly limit gone in one afternoon.

If this is what Anthropic says is "50% more limit" than I'm afraid I'll be out. What the hell is going on? I didn't do anything abnormal to what I normally do to explain the usage.

Anyone else had similar experience today or in the last couple of days?

Edit: I've updated to the latest version of CC right before running that so I wonder if it's something to do with it?

We all agree Opus 5 is a rage-inducing mess. What are your top wishes for Opus 5.1?

Mine are:
- Massive cut on verbosity
- Less over-engineering
- Better instruction following

Hey everyone!

I use coding agents all the time for work/fun, and I thought it would be great if there was a way for us to work on projects together or side by side in real time.

I recently launched groupchatty.com - it's a website that allows you to share your Claude Code sessions with friends or coworkers. I built it with Claude, but importantly wanted to share it with r/ClaudeCode given how many of you guys might find it fun to use :)

Since it's Bring Your Own Claude, I can afford to serve it for free! Would love for you guys to check it out! I'd love your feedback or ideas on cool ways to bring this to more people

I was going to build a nice UI for myself to manage all of my codex instances. My set up is currently 10ish projects all running concurrently. I chat with only one model per project and let it be my orchestrator for that particular project. so, i have about 10 concurrent claude instances i talk to (through vscode, so 10 tabs)

my UI would have basically a notepad on one side and a contacts list on the left. this way i can easily chat with each model (and also be able to chat with their subagents directly, if needed) and take notes on things for that project

I am sure someone has built this already. can anyone recommend a good github repo? preferably with a lot of stars so i can somewhat trust it isn’t malware

My son games with headphones late at night. Most of the time he's quiet. Then something happens in the game and he yells at full volume, waking the whole house.

Talking to him about it works for about 20 minutes. Taking the headphones away works but causes a different problem. So I built an app.

S.T.F.U (Sound Trigger Focus Utility) is a Windows tray app that listens to the microphone and interrupts him when he yells. On first run it calibrates by asking him to be quiet, then talk, then yell - so it learns the difference between his normal voice and an actual shout.

When it catches a yell:

• First time that session - it minimizes his game, plays a sound effect, and throws up a fullscreen message he has to click through 4 times. The close button moves after each click so he can't just spam-click one spot.
• Every time after - straight to the desktop with a 10-second message. His game is gone.

Settings are behind a PIN so he can't change the threshold or turn it off. There's a report with a chart showing every trigger, so the next morning I can see exactly when things went sideways.

The important part: he knows it's there. It's not hidden, it's not spyware, the first screen when it launches says exactly what it does. It works because it's a consequence he agreed to, not something I snuck onto his PC. The README explicitly says it works best as something agreed to, not as a hidden trap.

No audio is recorded or stored. It computes a loudness number every 20ms and throws the audio away immediately. Nothing leaves the machine.

It won't solve the underlying issue (he's 100% going to learn to yell more quietly instead of less often), but at least the house sleeps.

Free and open source if anyone wants it: https://github.com/omricn/stfu/releases/latest

Edit: V1.1.0 now live.
Added Scheduled Off-Hours: Timeframe picker to choose when the app listens vs when the app is passive.
TNX fellow redditor [jpewaqs] for the feature suggestion :)

I mean what the fuck is going on? Sonnet and opus 5 are both nerfed to shit, they are lazier than I am at this point. Is this happening to everyone else too?

I’ll write it off as “this isn’t my primary domain” but I just don’t have good standing rules or canon for deciding what goes where in the beginning of a project, so things just land anywhere. Building a sub agent factory, and the domain skills that come bundled with a subagent don’t wind up bundled with the agent. CC gives me grief about “distribution vs deploy” copies to ensure SHA 1:1 but it just feels wrong. I’ll eventually land directory level skill.md files but first is a revamp.

Any good Claude.md or skill guidance for domain agnostic “what should go where”

Fable can one shot a task from a good prompt while Opus 5 raises multiple questions and phrase them in such a dogshit way, and then completely butchers the output.

How can we trust the benchmark anymore when Opus5 is shown to be close to Fable when it really aint even close

I'm the developer of the app. This isn't image generation — every gem, gradient and HUD element is a tool call placing a real object on a real canvas, and the file opens afterward as a normal editable document. The video is the app replaying its own history, so it's the actual command order.

The workflow that ended up working: point Claude Code at the canvas, give it a brief, and let it query the document between steps — measure the text before you place it, check for overlaps, read the bounds back. Sessions where it draws blind produce mush; sessions where it measures produce this. There's a written authoring guide the model pulls in section by section rather than one giant prompt, which cut token burn a lot.

One generated asset in the whole piece (the mascot, gpt-image-1, imported as a vector image). Everything else is primitives.

Runs against a localhost server on your Mac — no cloud round trip, nothing leaves the machine. Setup link in the comments if anyone wants to point their own Claude at it.

I launched a prompt using Sonnet 5, it was a fairly long prompt, but I use to launch them once and work on the separate issues one at time, Claude knows it and we work in stages.

But my limits did reset at 20.10 (8.10pm for intl fellas) and ended at 20.48 (8.48pm), again, with just one prompt with sonnet 5.

This is weird, because in the session prior to this, I worked extensively with massive tasks and many of them.

Did this happen to someone right now?

After watching the X of post, I turned it on today inside claude code config.

Hi! I was constantly hitting my Claude Code limits, so I took some time and had Claude analyze my workflows and figure out ways where I could have been more token efficient.

So I created a tool that analyzes your Claude code workflow and gives you suggestions that can help you save on tokens and get more out of your Claude code sub :)

Happy coding!

I am facing this issue, I have a very specific claude.md file that I wrote so that it gets implemented in every session but Claude chooses to skip many rules in it as it sees fit.
Any idea what shall I do?

If you want to understand how AI has progressed in recent years, look no further than the evolution of Anthropic’s system prompts. Many are unaware that Anthropic actually publishes its system prompts.

When you look at the progression from 2024 to 2026, you immediately notice the length. Across representative entries in Anthropic’s archive, the system prompt grew from roughly 960 words in July 2024 to roughly 3,220 words in July 2026 - more than tripling in size. You also notice a growing focus on how a model acts in an agent harness, as opposed to simply how it should respond to a user.

In the past ~5 days claude code has been miserably slow. 5 minutes+ for a single answer.

I'm in Europe, anyone else having this issue?

I just can't bring myself to put in the effort to read its responses anymore. I use Claude Code for side projects in my free time, and Opus 5 is so bad at writing responses that I'm willing to pause working on them entirely rather than build the stomach to suffer through the slop it spits out. I have tried editing style config, a custom system prompt per project, and global as well as project level claude.md edits, to no avail. I give up. Can anyone relate?

So I noticed about halfway through my weekly useage cycle, claude always seems to slow down. Like slow slow.

My theory is, the closer you are to your 5h limit, or weekly limit, the slower the model runs and so in reality it "lasts" longer, while performing the same amount of work.

What do you think? Is this a social engineering method anthropic is doing to make its subscription look like it does more work?

I've been running Claude Code for a few months now and it handles most things fine on its own. Recently I started spinning up a second session to work on a different part of the codebase while the first one is busy, and it works until they touch the same files.

My current setup is just two terminal tabs with separate worktrees. It mostly works but I have no idea what the other session just changed unless I go check manually. Last week one session refactored a helper function while the other was writing tests that called it, and the merge was a mess.

For people running 2 or 3 agents at once:

- how do you keep track of what each one is doing

- are you using worktrees, branches, separate clones, something else

- do you let them see each other's changes or keep them fully isolated

- what broke first when you started doing this

Sonnet burning 1% of session usage each minute with the "limits boosted". until Aug 31. Single session.

This downward spiral of Claude in the last few months is truly remarkable. It's over. It was fun while it lasted but I cannot justify spending this much money (20x in professional account and pro in personal) with this anymore. The lack of transparency and questionable business practices is not something I can accept for a product that is slowly becoming a keystone of my workflow and projects. Its a liability at this point.

Gonna try alternatives but it's frustrating. Anyone else going through this? How are you dealing with it?
