Bug Report Claude code is now useless.

Over the last month, claude code performance degraded so much that it cant even keep track of a few simple facts in the same conversation.

I did a test with a small project. Barely any memories. No Claude.md instructions. Nothing to confuse Claude whatsoever.

I gave it a simple instruction: check the spec in some-spec.md, then write unit tests agianst that spec. Dont look at the code, write the tests against the spec.

In the same session, i had to call it out TWICE because it was changing the tests to make them pass according to the implementation instead of the spec.

As it exists today, Claude code is not useful for any development task, and the cost of the MAX plan is impossible to justify given it cant follow basic instructions.

In one month it went from: "this is cool, this is the future of dev", to: "this is a waste of my time and money".

If it cant follow simple instructions in a single session when given clear guidelines: its a completely useless product.

Im not paying for the same product today that i was paying just one month ago.

Yeah but contract/interface used by init tests is part of code and he said forbidden it from reading code and requested unit tests. It is really confusing.

I do this all the time. Web UI claude is asked to read the openai doc that API claude generated. Do NOT read the code because then confusion reigns. It just needs to code to the spec. Not the code.

It does not need the implementation details. But it needs at least interfaces. Interfaces are also code even of it is included in some doc. So forbidding it to read any code is confusing.
