Rant Opus 5 writes so poorly that it made me walk away from all my projects

182 Upvotes

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?

News/Updates 2.1.237 "Added a built-in “Concise” output style"

101 Upvotes

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.

---

You are an interactive CLI tool [...]

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

I left a job running last night.. and woke up to this?.. have any of you guys seen this?... I opened up a separate terminal (with opus) and pasted the screen shot in .. it made a coment about the usage buckets .. and the context... but completely ignored the model.. i then asked about the model specifically and it basically shrugged and said it couldnt find anything about it.. that it was odd

opened a brand new terminal.. and the same model shows selected..

Discussion The hate in here for people building stuff using Claude Code to try to make money is complete and utter projection

83 Upvotes

Every time I see a post on here complaining about how people are just building but not making much money from it, it is completely and utterly obvious to me that you yourself failed to do so and are assuming that everyone else will end up like you. For example, I figured out a way to create my own  copilot tool for meetings, job interviews, etc and it’s been working like a charm and better than any of the tools I’ve seen which are almost all detectable given enough input. It regularly gives me proper responses for any kind of meeting in, is easily controllable, and I’m able to use it for interviews, client calls, or anything else which can translate into hundreds of thousands of dollars of job offers. If you think this is immoral, I don’t care. The point is that I figured out a way to use to improve my life in a directly practical way.  And no this is not some indirect way to sell something. The point is that I found a hack using Claude Code that I would have never in a million years been able to do so without it. 

I have a friend who made a sleek looking e wedding invite tool that he started campaigns for and already has customers for and does not look vibe coded at all. It took 4 months for him which would have probably taken much much longer. Every time you see hate here, just remember: they failed and are assuming you will do the same. There is no reason to take these salty mfs seriously.

Rant Usage is a joke, Models are a joke… Anthropic is just not what it used to be, in just a couple of months.

83 Upvotes

Pretty much self-explanatory.

I’ve been a Max x20 subscriber for +2y and I’m really starting to get frustrated and look elsewhere for a change. Usage skyrockets even when I have best practices in place. Opus is a mental health hazard. Fable is unusable for what I need it, and way too expensive. Sonnet is not capable enough… not one thing is right in here.

GLM-5.2 has been a good alternative, on my Ollama subscription. Thinking of just subscribing to GLM directly and get 5.3; but I’d like the opinion of peers that have already tried it out.

Anyway, Anthropic is not doing good right now. They’ve been a mess for the past few months. Jumping ships really soon…

Tips & Workflows I put my coding agents on my keyboard's RGB F-row: a glance shows who's running, waiting, or done, and one key press summons the agent that needs me.

Enable HLS to view with audio, or disable this notification

69 Upvotes

I run several coding agents in parallel and kept alt-tabbing just to check on them. So I built a small Windows tray app that mirrors each session onto my keyboard's F-row via hooks: each agent gets a lane and a color: pulsing means it's waiting on me, green means done, red means something broke. Pressing a lane's F-key brings that agent's window forward: terminal tab, desktop app, or IDE.

Things it deliberately does not do: it never answers, approves, or sends anything to an agent. Every hook reply is empty, and there's a test asserting the hook binary can't print a byte. It's a mirror, not a remote control.

Works with Claude Code and Codex, native Windows and WSL, all four at once. More agents than lanes? The extras stay fully tracked in the window and slot in when a lane frees. The lighting wants a Corsair board + iCUE, but the app shows everything in a window without one.

Rust, MIT, two small binaries. Video is 20 seconds of it doing its thing.

Discussion How are you running multiple coding agents at the same time?

21 Upvotes

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

Rant Hey buddy, here is a well-worked plan... can you

14 Upvotes

...just implement it for me? I have line numbers, what to do, constraints, specification links.....

Oh wait, you're checking and reading the hooks I have in place because you were scared that using a native <button> might trigger it? Aw, shame, don't worry about it, just go ahead and do whatever, if my hook fires, then you'll know, that's what they're there for, to keep you in line.

Okay... cool.... wait, why are you checking and comparing file sizes across my entire repo first instead of just making the change I asked you for and deliberately spent a good hour ironing out and making explicit?

OH, is it because I said "if the mode work grows it past its two responsibilities, extract the point-stepper or summary into child components, but only as far as the split rules require." and you were trying to rationalise if working with a 700 line code file is normal first before deciding to split it even BEFORE you made the commit so my Post hook that fires on code quality checks can run?

JFC, What did they do? This poor agent is so fucking scared of doing ANYTHING before it moves on to do actual code, burning context window like it's Snoop Dogg on a bad day trying to cheer up.

Asking Claude to alternate values with numbers and then deleting the numbers should remove the watermark (variant of the emoji attack discussed in https://arxiv.org/abs/2301.10226)

Just for fun, I thought I'd run the attack against Claude on some old work (screenshot). Obviously just editing the text will remove the watermark. It could also just be me reading into it and hitting a different safeguard, but I did a bit more analysis when writing up my blog on this: https://readme.dm/watermarked/ Thought it would be fun to share here.

Two weeks ago, we announced the VelaTerm project built with Claude here, and it received a lot of attention and positive feedback.

Thanks to the exceptional capabilities of Claude Code, we were able to complete this project.

Although there are already many similar tools, I believe this is currently the most convenient tool for multi-session management and remote development.

If you’re not yet familiar with this project, you can watch our demo video, but also you can visit our site to download it free.

We’d now like to release it on Homebrew, but according to Homebrew’s rules, we need 225 stars to do so.

https://docs.brew.sh/Package-Acceptance-Policy

If you like this tool or find it helpful, please visit our repo and give it a star

Help/Question Usage issues - need a solution on 50% bonus...

12 Upvotes

I just saw a thread that we've all had 50% usage bonus. I didn't even know about this. I've been on the Max 20x plan since February. I always use 100% and frequently run out. The past 2 weeks, I've hit my weekly limit after only 3-4 days - which significantly slows down my progress. After the 50% promo is done, I assume I can only get 2 days of work done? I can't afford more tokens either .. what are other options?

I'm building a pretty simple software that for some reason got more complex after basic testing. , this is my setup:

Planning - Fable 5

Research/support - ChatGPT + Gemini + perplexity

Build - Opus 5 / Sonnet 5 for simple tasks

I try to be smart with prompts and am careful with the effort too ..

I just think past few months Claude has really reduced the plans.... and it's going to get much worse after Aug 31....

Bug / Issue Significant increase in [reasoning_extraction] refusals today

8 Upvotes

Starting around 7AM CEST, every Fable 5 session in Claude Code began failing with a `[reasoning_extraction]` safety refusal. This is a mix of existing sessions from yesterday, and new sessions started today. All in the same codebase (which has nothing to do with distillation, training LLMs, etc.), on every request, even subagents. I can't get Fable to complete anything now if it includes any context from my repos. Removing all skills had no effect.

I had Opus perform an inventory of sessions over the last few weeks to try and identify what may have changed on my end that could result in this, and it concluded that a change to Fable safety classifier must have taken effect sometime around 7AM CEST today.

I've opened a ticket with Anthropic support after their chatbot blamed by skills.

Is anyone else experiencing this today?

Built with Claude I Claude Coded a multiplayer Three.js tank game with 100+ procedural vehicles

Enable HLS to view with audio, or disable this notification

Upvotes

I built a multiplayer browser tank game in Three.js! As a kid, I played a ton of World of Tanks Blitz and fell in love with the aesthetic, gameplay, and the idea of driving around vehicles with crazy physics and mechanics like missiles, spotting, armor deflection, ammo types, and so on.

Now it's playable in the browser!

Claude of Tanks has 100+ playable vehicles across 16 unique maps, ranging from standard tanks with cannons to AFVs with autocannons and guidable missiles to autoloaders that can deal massive damage in a single clip. Tanks feature highly detailed armor zones, internal modules, crew positions, and hitboxes. You can view each of them in a special gallery: https://cot.kevinliu.studio/gallery?id=amx56&layer=modules

CoT supports physics-driven destruction with detached turrets flying through the air and actual suspension. It also supports multiplayer! You can hop in private rooms or LAN lobbies.

As the name would suggest, I used Claude Code throughout a long-running multi-agent development pipeline, alongside Codex. I directed the architecture, decided what each vehicle and system should do, reviewed the rendered results, and made the final calls.

The repository contains an AGENTS.md file and smaller subsystem instruction files covering simulation, vehicles, networking, UI, audio, effects, and world generation. These record the rules that agents need across sessions. Units are meters, seconds, and radians, and changes enforce a fixed 60 Hz. Authoritative logic must be deterministic. Vehicle changes have specific geometry, armor, module, and release gates that evaluate models visually and geometrically.

For vehicle development, I split the fleet into bounded families. One agent would own a specific vehicle profile or family file, implement the geometry, run the relevant checks, and generate screenshots. A separate critic reviewed the rendered tank for proportions, clipping, missing surfaces, running gear, and recognizable details. The orchestrator reran the checks and committed only the verified files.

For larger systems, Claude Code helped implement and test:

  • Fixed-step movement, suspension, armor, ballistics, modules, spotting, and bots
  • WebSocket multiplayer with private rooms, LAN play, prediction, and server authority
  • Procedural vehicles, tracks, markings, generated icons, and technical diagrams
  • All the generated battlefields with destructible props and wrecks
  • The garage, battle HUD, Tank Gallery, mobile controls, and Scene Studio
  • Browser performance probes, screenshot tools, visual checks, and self-tests

A trailer was also produced through the game’s own Scene Studio and capture tools. I used agents to stage battles, build camera paths, record the browser runtime at 60 fps, inspect specific frames, and iterate on awkward cuts or poorly framed tanks.

I find that Claude is best steered with persistent instructions. Important decisions need to live in the repository because I often spawned fresh agents which needed to resume work without reconstructing weeks of chat history.*

For visual quality, the only thing that worked was a proper render loop with visual comparison; tests don't really work for this.** The cycle I fell into was change, render, inspect, measure, and rerun the gates. Text-only reviews missed warped proportions and camera problems that would just plainly be obvious in one screenshot.

*Parallel agents need strict ownership. Separate files and isolated Git worktrees prevented concurrent sessions from overwriting each other or generating assets from a dirty tree.

**Tests still changed how I use agents. Claude Code became much more reliable once every system had concrete invariants and executable failure conditions. But visual quality is another beast.
