Today we’re launching maps in Eraser: AI-powered architecture maps.

Eraser’s AI builds an interactive map from your cloud, code, CMDB and spreadsheets. Every level and every state of a system, in one map 👇

i think i kept seeing people say "monorepos are good for agents"

but we just switched to multi repos. i have a hard time caring about the benefits of monorepos anymore

I've been working on a new visualisation experience for users in @event_catalog .

With "Levels" you can now decide what view of your diagram you wish to see.

Level 1 - Domains, systems and actors
Level 2 - Services and data
Level 3 - Messages and channels

These new levels can and your architecture through different lenses either staying at a high level or diving deeper.

Now live 🙌

We've been working on building trace intelligence across all your company sessions. We're building dimensions of trace data especially relevant to the offices of a CTO, CISO, and CFO. You'll be able to answer things like "how often do files in your codebase show up in agent read does it cost" (an example visual below)

This is a fun but gnarly data engineering challenge. But IMO the real story is all the software we are creating along the way. We're building internal tools to evaluate schema choices, we use data from our agent to evaluate the types of queries to optimize for (using Jev and Luna to classify), we build visual profiling tools test query performance throughout. Making software now is so much more fun and interesting.

Anyways, I can't wait to show this stuff off. Your agent trace data contains multitudes and you need many ways to look at it. Also, if this is interesting enough that you might want to run a pilot, please DM!

I spent the majority of my career building observability tooling

this tooling should be used to close the loop between production and coding agents, in service of self-improving software

I put my thoughts down

People ask me how I ship omarchy sw so fast. 🧵

The answer is Clarity.

Clarity is where all my projects live, from the first idea to running live. Every project gets a map, a status, its questions and decisions, a backlog, testing and its GitHub, in one place. Every AI chat fore it starts.

Made with Clarity with a buddy of mine, lets call him Daniel, not on X and wont be.

Here's Blip, my iMessage app for Linux, going through it.

👀👀 "[…] we provide several examples of AI mistranslations of natural language (NL) statements and proofs into Lean in practice, resulting in mismatches between NL proofs and their Lean 'verifications'. These include OpenAI's announced Navier-Stokes proof. In particular, we show that the formalised Lean proof does not correspond to the NL proof of blow-up of solutions to the Navier-Stokes equations."

working at a higher level of abstraction has always required understanding the lower level ones, I don't think coding agents changes this

I built Petal, a free, open-source disk-space explorer for macOS.

The chart draws itself while it scans. It flags what's safe to delete (Xcode builds, node_modules, caches) and tells you exactly what deleting frees.

Rust + GPUI. Inspired by the recent syntax.fm v1PO2akUl

maybe don't ship 2k+ file PRs

But if you do, let the PR explain itself

Try it here: github.com/coldteadotai/p…
A pull request with 2,200 files, 1M+ changed lines, and 400+ inline comments.

Impossible to review? Not if you have the GitHub Copilot app. ✨

The rebuilt pull request view keeps even this extreme diff fast and smooth. 🧵
