Agentblame: A deep dive into line-level AI code attribution
A deep dive into how Agent Blame attributes code changes to AI agents.
Coding agents are a new infrastructure primitive
Coding agents are transforming from app -> infra. That changes how you build agentic products.
Why we built our own LLM observability system
We needed something that Sentry spans couldn't provide.
Using an expensive model made our agent 75% cheaper
How we reduced code review costs by treating cost like a product metric, building the right measurement, and running a tight loop of experiments.
Raise the ceiling
A manifesto for the next generation of software development.
