Hey Alex, we had similar thoughts at Retriever AI of moving from webpage interactions to reverse engineering the underlying APIs. Compared to your our approach, we are doing this entirely within a browser extension so meeting users where they already doing their existing work. Within the extension just record doing a task, we reverse engineer the APIs and write a script. Then execute the script from within the webpag…

cool . can you give me the link of the tool

The tool: https://www.rtrvr.ai/

Interesting. We essentially do the same thing, but with MITM. We have a chrome extension internally, but have found it's a bit of a clunky interface. Might be releasing one soon. The approach with executing script in webpage is interesting. Best of luck!

Yea would love to try out the extension! ITs always interesting to see everyone's design approach.

I really don't want to install an app on to my laptop, especially an MITM, so I think extension would be better.

Earlier quoted context omitted.

We’ve essentially been using that “recursion” to tune our agent. Having the agent build itself is not something I would have ever thought of though. Curious if you find it genuinely creates specific enough tools for it to be worth the setup time? I have a claude skill that takes in a chat and then offers tools/fixes to system prompt. Have found that + the anthropic harness engineering blogs to be super useful in maki…

Have a look at https://github.com/adam-s/agent-tuning . Now, I'm working on developing the evaluation, the part that quantifies the performance of the agent. I'm having a hard time explaining it. You should be able to point Opus 4.7 to the repository and it will know how to set it up in your project. You are welcome to send me an email at [my_username]@gmail.com if you want to talk about some of these things that I'm…

I built the same thing as this just for websites. [0] I'm more interested in using Claude recursion to tune itself -- the agent writes itself, the agent -- than hacking websites. It is a good demonstration that 47 iterations of a recursive Claude agent writing itself to decompose any transport. I've tested it against YouTube, Twitch, Ticketmaster, and Yahoo Finance. It will detect any transport like JSON, WebSocket,…
