Wrapping up the writting part for my talk at @perfnow.nl this weekend and I'm beyond excited for this one. Prepare for a deep dive folks!

Whist trying out my demo for the Agentic Perf Analysis and Debugging, I managed to use my V0 and my DevTools MCP servers to debug one of my V0 demo chats.
Using animation frame insights no less 😃

We're almost there!
After spending the week hacking OAuth support into Mastra MCP client class and getting the toolcall aproval workflow to an MVP state this sprint is soon coming to an end.

I've managed to implement OAuth into Mastra MCP client (on a fork of mine) and now it talks to my V0 remote MCP server (that uses OAuth).
Gotta work on the HITL parts of the MCP tool call as the spec requests, but we're moving now 😎.

Finally got my @v0.dev MCP server deployed to @vercel.com and successfully implemented the custom OAuth flow (to just just API key exchange).

Previous vs Current INP whilst browsing through the catalog.
V0 🤝 DevTools
Now up to more experimentation over the weekend, I want to allow the code editor to connect via github and download the project to have IDE <> V0 flows.
But the agentic perf workflow is promising already

Having V0 talking to DevToos for some perf analysis and working together to improve performance 😎

Hacking on something over the weekend after the V0 public SDK was announced.
Up next: integrate V0 MCP <> DevTools MCP for self healing generations

Today I've invited 26 more people to try out PerfAgent. I'm closing in on the opensource milestone (just gotta cleanup more before I can have an open house 😅)
I'm looking to expand trace support to OTEL soon, converting OTEL spans into DevTools.

When thinking about perf, now living in Europe, it is easy to forget how skewed our experiences can be.
Most of this map is dark, meaning that has little or no 5G connectivity.
Though I'm impressed with how India is connected, Brazil (where I come from) is unsurprisingly dark.

A really good first try on the DevTools MCP server, gathering interaction insights and also 'general' insights using animation frames as a base 'unit of work' and extracting info using the AI helpers baked into @chromium.social itself.
Profiling and fixing perf cannot get any easier than this.

It might be todo with the current outtage problems, but
@github.com is showing github.com/chromium/chr... contents instead of github.com/chromium/chr... on @chromium.social GH project.
Nevertheless, it is a fascinating find to me 🤔

Working on improving the LCP reports from agent.perflab.io
Not only the reports are now more meaningful, I've been working on creating network activity visualization for the reports so we can better visualize the impact on different requests on the LCP timming at a glanceble fashion.

This has been quite a ride! But now I have a working preview build with the agent analysing the call tree for INP events in place! Including using my own canv

Time for another agent.perflab.io update!
Very close to start getting a few test users in for some direct feedback! I've been working on getting more value out of the Web Vitals reports generated by the agent. Starting with INP reports.

Ok, deep research agent workflow objectives are getting very well tunned. Analysis Plan 🤝 Execution
Query: "Can you research on the most common causes for poor INP scores?"
