Code Review for Claude Code | Claude Claude Code now dispatches a team of agents on every PR to catch bugs that skims miss. Available in research preview for Team and Enterprise.

"Reviews are billed on token usage and generally average $15–25"

sounds high, but it means they take themselves to have solved the problem. the challenge with LLMs is to get them good enough where throwing more tokens at a problem gets you more. then you throw as many tokens at it as you need

This is so accurate. The military spending is siphoning money from other areas like healthcare and education.

Skills are among the most consequential new tools for AI, and Anthropic just released a very impressive nontechnical Cowork Skill that builds Skills, including doing interviews & providing benchmarks through parallel tests

I think you still need to add the human touch but this is a big leap forward

Thanks! The README says: "Blocks (blocks/*.yaml) — short text that appears in every prompt." Doesn't that cause identical YAML blocks to appear repeatedly in the context window?

PROMPT: Thanks. I notice that if the current conversation is compacted while you are busy invoking tools (or perhaps just while you are responding to me), you see my most recent prompt a second time following completion of the compaction. This has happened in other conversations too. I don't think I can do anything about this on my end, but would it help if you created a high priority memory so that this won't cause confusion in the future?

CLAUDE: Done. That should help future sessions recognize the duplicate-prompt-after-compaction pattern and avoid re-doing work that was already completed. You're right that it's not something you can control — it's a side effect of how the compaction process reconstructs the conversation state.

Also, when compaction happens in the middle of a response, Claude sees the prompt a second time for some reason. Probably a harness bug. Told it to remember this can happen, so it won't get confused.

A few days ago, I had a very long conversation in Claude Desktop that had been compacted at least 5 or 6 times. Finally I got a message (not from the model but from the GUI) saying this conversation cannot continue, please start a new one.

I much prefer working with Claude Desktop or Claude.ai instead of CC. Their system prompts make them easier to talk to. So I'm working with Claude to design a way for Claude Desktop to do what CC can do. (Also with persistent memory.)

Instead of forcing models to hold everything in an active context window, we can use hypernetworks to instantly compile documents and tasks directly into the model's weights. A step towards giving language models durable memory and fast adaptation.

Self-improving AI Executables Write programs in your own words. Run them in a secure sandbox. Install them like any other tool.

Running AI agents as Unix executables that self-improve has been one of my wilder ideas lately.

You can pipe agents: `think weather | think song`

The agent eventually writes a determinative script after enough runs for simple programs.

It’s as secure as a browser too.

This has been long suspected, but I think this is the first official accusation, right? I wonder if OpenAI has also seen distillation by those labs using their models.
