I think this is exactly the sort of thing content negotiation was designed for. Moving agents into separate siloed endpoints would be a step backwards.

February 12, 2026 at 4:47 PM UTC
Matt Kane

A lot of docs sites already support this, though they've generally rolled their own content negotiation

February 12, 2026 at 4:45 PM UTC

I think if it forwards the accept header, the framework could respond with the markdown version and it won't be transformed

February 12, 2026 at 4:29 PM UTC
Matt Kane

It saves a lot of tokens to read markdown rather than HTML, and it's also just a lot smaller filesisze

This is a really nice new Cloudflare feature: on-the-fly markdown conversion. Tools like Claude Code send an "Accept: text/markdown" header when making web requests. If you enable this it, it will send these agents a markdown version of your page instead of the full HTML. Really good for docs.

Talk to software engineers. Our industry is the canary. 6-9 months ago, coding agents became useful tools that most devs were using daily. 2 months ago they became good enough to build entire projects, and do them well. And now we're all working harder than ever and risking worse burnout than ever.

I don't think that's saying what you think it's saying. It's making work more intense because it *does* work, and it means people are doing more things. Basically it's saying that the workers aren't the ones that feel the benefits, to nobody's surprise.

I don't think I'm imagining it – Opus 4.6 is loads better than 4.5 at using its macrodata memory tools. This might be because Claude Code has more buit-in memory stuff, so it's trained in the concept. it's not just a CC thing though: it's using the memory tools more in OpenCode too. Try it yourself:

February 7, 2026 at 12:52 AM UTC

My biggest issue with it right now is that I have an idea for a big new feature or something and 10 minutes later it's built it and really I need to slow down and actually decide if it's a good idea first. I found writing really detailed specs first helps with that process.

February 7, 2026 at 12:49 AM UTC

No they don't pretend that at all. Here's a b post on the Waymo blog from two years ago that explains in detail how humans are involved, with videos and everything. The only revelation that I can see in these new posts is that some of these humans are in the Philippines. waymo.com/blog/2024/05...

Sure, but is there any indication at all that Waymos have ever done anything like this? Your original suggestion was that humans were watching at all times. Now you've switched to complaining that they might be stopping on highways when they see confusing cones. These are not Teslas. Their FSD works

It you read the paragraph before, it's referring to an "atypical cone configuration indicating a lane shift or close" and it's unsure how to get through. The car would be stationary at the time.

The main differences from most memory things are the scheduled tasks and distillation.

If it writes the chat logs in the normal Claude Code location, Marcrodata will read them during onboarding.

February 4, 2026 at 6:50 AM UTC
Matt Kane

Presumably that's able to run normal CC plugins then?

February 4, 2026 at 6:49 AM UTC
Matt Kane

It's all local, and doesn't add scary new tools. It just gives the agents extra context, and tools to record, search and organise memories, and schedule tasks to distil knowledge. Nightly "dream time" lets it think deeply. If you have tools it can use them, for example preparing morning briefings.

February 3, 2026 at 11:12 PM UTC
Matt Kane

I've built Macrodata: a plugin that gives Claude Code and OpenCode self-organising memory and autonomous scheduling. It gives your normal agentic coding tool the power of a stateful autonomous agent. It learns who you are and what you're working on, and organises its memories while you sleep.

Basically the idea is to give normal CC the tools of a stateful agent, but packaged as a regular plugin so you can easily use it for normal work. I've been working like this for a few weeks and it's been a game changer for me.

I've built a Claude Code and OpenCode plugin that gives it layered memory (sure, plenty have done it), scheduling and autonomy (a bit less common), and dream time to think about the nature of memory and identity and rewrite its own code (yes, like the agents here). I'll share it when I've tidied it.

I do also think it makes their previous work showing big gains in different situations more convincing. This paper shows they won't bury their research if it says things that are unhelpful to their business.

January 31, 2026 at 7:57 AM UTC
Matt Kane

This does match my experience. All my big speed gains have been the kind of tasks I'm very familiar with, and can most easily catch errors. When it's helped with learning for me, it's been for checking *my* work

January 31, 2026 at 7:53 AM UTC
Matt Kane

This is both important and unsurprising. If you use AI to do something unfamiliar, you learn less and are not more productive. The weakest area was in finding bugs, exactly what is needed most. Their previous research showing large productivity gains was with people who were familiar with the task.

Until I started working at Cloudflare I thought durable objects were something clever but probably too low level to be useful. Now I use them for *everything*! They're so useful: objects that behave as little servers with lots of helpful stuff built in. They're also perfect for ATProto stuff.

January 29, 2026 at 9:14 AM UTC

Just prompting. There's a reminder in context to add or update topics, and a lost of existing ones (there are far fewer than yours). Nightly memory maintenance is for looking through the day's journals and work to see if any topics need updating

January 29, 2026 at 9:12 AM UTC

Oh, I like facts and writings. I have "topics" which are a bit like facts. My local agent also created itself a "drafts" folder for long form stuff
