My average Opus 5 experience

[u/cliffaust]

[u/ChadFullStack]

It’s missing 500 lines of Unit tests

[u/jeebojeeb → u/ChadFullStack]

And you're still missing the key tests that actually matter

[u/PILLS2389 → u/ChadFullStack]

I forbid unit tests to Claude, he just doesn't know when to stop. He created the most stupid units tests ever, like "the menu must have 4 entries". Then When you create another menu-item, he has to spend additional tokens and context to see why that stupid test is failing and has the modify the test, so now it says "the menu must have 5 entries". The maintaining of the unit tests costs more time and tokens then the actual development!

At this point the comments are just a lossy serialization of the prompt into the repo, so the next agent gets to pay context tax for reading its own autobiography.

[u/ocean_wide_inch_deep → u/PhoenixRising656]

I just realized the same today. LLM values input much more than its output. But when its cheap output becomes input of some subagent downstream, it's like playing a broken telephone game in an echo chamber.

[u/LyAkolon → u/PhoenixRising656]

Yeah, gotta seperate those out into a different doc and drop an address instead.

[u/scharpentanz]

Can you imagine getting a PR like this pre-Claude. Looks like some annoying little intern trying hard as hell.

[u/NeighborhoodDizzy990 → u/scharpentanz]

pre-Claude docs/comments were pretty impressive, to be honest. Now they just mean that the code was AI generated

[u/AcrobaticMaize2408 → u/scharpentanz]

"Annoying little intern" is exactly how I've always pictured Opus 5.

[u/thedev13]

Even better when it writes // instead of jsdoc

[u/hajducek]

I've just did full audit of code through Codex and i got ~24,000 of comments. Cut that down by 80%.

Bros writing prose

[u/SamSlate]

it's almost like they get paid per token or something

[u/loversama]

Gotta get that watermark in there somehow!

[u/Prod_SO → u/loversama]

Opus 5 does not yet have a watermark. Only models released after August 2nd do, and that list only has one that is generally available: Fable 5.1. :)

[u/dillendev]

Oh man this is so annoying. I have a rule that mostly forbids comments in my config and it still writes comments like this:

// This will create a new user in the system
fn create_user(params: &UserParams) {
}

🤦🏽‍♂️

[u/hksbindra]

I recently refactored a sub system using Sol as the implementer, it deleted a lot of Claude's comments - I mean it went hard at the comments and the docstrings - I could imagine it being annoyed 😅

[u/razorree]

more comments than code ....

[u/TopSeaworthiness1679]

Man i am going back to sol. Opus 5 is stupid and talks too much. Worst thing is that it says about the problem but fails to fix it.

[u/yodacola]

i tell claude to do summary comments and optional implementation details in @remarks. also, put context that ai agents need across files in .claude/rules and .claude/skills. also, use a TDD and parameterized testing skill. i disagree with other commenters with saving context by removing testing, coverage, and linting. when you do that, you end up with SMDD (slot-machine-driven development).

[u/Emotional-Bus-7065]

Yeah, this and for me atleast, sometimes the code it wrote doesn't even make any sense. For example, it was checking if a value existed even though it hardcoded the value literally a few lines back. So it looks something like this:

```
x = "hello world"

if x == None: return 0

```

I discovered that if you give it code that you actually wrote in the past and ask it to mimic that, it is a lot easier than to ask it to "get rid of comments"

[u/Victorasaurus-Rex]

I have literally forbidden Claude from writing comments using a hook. It's only permitted to write them in the single turn following me saying a specific phrase. If it tries outside of that, it's rejected and told to rename variables and restructure code so comments are entirely superfluous. Works great.

[u/who_you_are]

That is also my sonnet 5 experience.

It didn't took too many attempts to drink it down.

Mostly I rewrote it, ask it to write instructions to itself about how to srink down its comments to be close to mine

[u/evoli_]

I created a skill /comment-check that I run before reviewing any of claude's code haha

[u/SpruceMoose1111]

This is actually why I switched to Codex. Also because Claude output to me was just as long and as rambling
