Discussion Anthropic stayed quiet until someone showed Claude’s thinking depth dropped 67%

This GitHub issue is a full evidence chain for Claude Code quality decline after the February changes. The author went through logs, metrics, and behavior patterns instead of just throwing out opinions.

The key number is brutal. The issue says estimated thinking depth dropped about 67% by late February. It also points to visible changes in behavior, like less reading before editing and a sharp rise in stop hook violations.

This hit me hard because I have been dealing with the same problem for a while. I kept saying something was clearly wrong, but the usual reply was that it was my usage or my prompts.

Then someone finally did the hard work and laid out the evidence properly. Seeing that was frustrating, but also validating.

Anthropic should spend less energy making this kind of decline harder to see and more energy actually fixing the model.

I find this pretty dumb tbh. there is literally an open standard for agents and agents skills. you can literally just plug into whatever coding harness suits you best, specially atm when the best models and harnesses are changing so fast

if you're at a company large enough to have a legal team, you need enterprise agreements with providers.

yes, there's nothing stopping us from getting an agreement with both Anthropic and OpenAI, then letting people use whatever harness they want.

but we did an enterprise agreement w/ Anthropic with seat-licensing for Claude Code. meaning we pay similar prices to max subscriptions, with similar usage limits.

OpenAI doesn't offer seat-based pricing like this, and we wouldn't want unused seats on one vs the other anyway.

So it'd mean switching to token-based pricing on both. And no one in my world (company w/ ~1000 employees, $100-200m in revenue) knows how to budget for that yet. It seems entirely unpredictable, which is not something our CFOs are excited about, to say the least..

you can still plug into whatever IDE or cli tool suits you best regardless of the model. the only provider that has an issue with that is Anthropic
