i have never seen this before - where you offer something and then take that away

im running some experiments on this but based on what i have seen on my own personal data - I dont think this is true

"given that Opus 4.7 on Low thinking is strictly better than Opus 4.6 on Medium, etc., etc.”

Opus 4.7 in general is more expensive for similar usage. Now we can argue that is provides better performance all else being equal but I haven’t been able to see that

yeah thats is my biggest issue - im okay with paying 20-30% more but what is the ROI? i dont see an equivalent improvement in performance. Anthropic hasnt published any data around what these improvements are - just some vague “better instruction following"

Yeah this is a bit crazy and not surprising at all.

The limits have always been opaque and you never know when they change.

I started building an open-source local proxy that logs every rate-limit header Claude Code sends.

I am using it to track and get a better sense of the 5h and 7d weekly limits.

Some initial data from 11 observed 5h sessions on Max 20x: - 5h budget: roughly $120–$280 per window - 7d budget: roughly $1,300–$1,900 - Separate Sonnet-only 7d budget at ~$150 - 95% of tokens are cache reads. They barely move the meter.

It’s open source so more people can run it and we can figure out the real numbers.

https://github.com/abhishekray07/claude-meter

The dropping requirements problem is real. What's helped us is breaking the spec into numbered ACs and having the verification run per-criterion. If AC-3 fails you know exactly what got dropped.

I do it per feature, not per step. Write the AC for the whole feature upfront, then the agent builds against it. I haven't added a spec-validation step before coding but that's a good idea. Catching ambiguity in the spec before the agent runs with it would save a lot of rework

Agreed. The spec file is context. Writing acceptance criteria before you prompt provides the context the agent needs to not go off in the wrong direction. Human leverage just moved up and the plan/spec is the most important step.

Parallelism on top of bad context just gets you more wrong answers faster

This is great. The tests in this case are the spec. When you give the agent something concrete to fail against, it knows what done looks like.

The problem is if you skip that step and ask Claude to write the tests after.

i think the friction has moved upstream - now it's working on the right thing and specifying what correct looks like. i don't think we are going back to a world where we will write code by hand again.

yup, agree - i spend most of my time reviewing the spec. The highest leverage time is now deciding what to work on and then working on the spec. I ended up building the verify skill (https://github.com/opslane/verify) because I wanted to ensure claude follows the spec. I have found that even after you have the spec - it can sometimes not follow it and it takes a lot of human review to catch those issues.

Test theatre is exactly the right framing. The tests are syntactically correct, they run, they pass but do they actually prove anything?

yeah honestly thats what i am struggling with too and I dont have a a good solution. However, I do think we are going to see more of this - so it will be interesting to see how we are going to handle this.

i think we will need some kind of automated verification so humans are only reviewing the “intent” of the change. started building a claude skill for this (https://github.com/opslane/verify)

thats a great idea - i have been using codex to do my code reviews since i have it to give better critique on code written by claude but havent tried it with testing yet!

yeah i have started using codex to do my code reviews and it helps to have “a different llm” - i think one of my challenges has been that unit tests are good but not always comprehensive. you still need functional tests to verify the spec itself.

Yeah just wanted to see what the bottlenecks would be as I started pushing the limits. Eventually made this into a verification skill(github.com/opslane/verify)

yeah i have been hearing a lot more about this concept of “digital twins” - where you have high fidelity versions of external services to run tests against. You can ask the API docs of these external services and give it to Claude. Wonder if that is where we will be going more towards.

yup agree - i think have specs and then do verifications against the spec. I have heard that this is how a lot of consulting firms work - you have acceptance criterias and thats how work is validated.
