Mario Zechner just dropped the most based take on the whole AI coding frenzy and Iām quoting the entire 2nd half of the blog in my head on repeat.
Takeaways from āThoughts on slowing the fuck downā
(mostly direct quotes)
Agentic search has dogshit recall.
Before an agent touches any code itās supposed to first search the entire relevant codebase. But current agentic search is broken, even if you give it a queryable index, LSP server, or vector DB. The bigger the codebase, the lower the recall.
Low recall = the agent literally doesnāt see half the code it needs ā it makes garbage architectural decisions that compound into unmaintainable slop.
So how should you actually use agents right now?
Only on scoped work where the agent doesnāt need to grok the full codebase.
The loop must be closable (it can evaluate and fix its own output).
The output must not be mission-critical (side projects, internal tools, experiments, all the stuff that can break without taking your product down).
You are the final quality gate. Always.
Let the agent do the boring, rote, āIād never have time for thisā stuff. Let it explore ideas you wouldnāt otherwise try. Then you review everything it spits out, keep the parts that are actually good, and finalize the implementation yourself. (Yeah, you can even let it do the final polish, but only after youāve signed off.)
Review every single line the clanker generates. (This is something Iām struggling with currently)
Anything foundational like architecture, public APIs, core data models, security boundaries, write it by hand.
Or at the very least pair-program with the agent so you stay in the code the whole time.
Because slowing the fuck down and suffering a little friction is exactly what lets you learn, grow, and actually understand your own system.
Youāll sleep like a baby knowing you still have an idea what the fuck is going on⦠and that you never surrendered your agency.
Quote-tweeting this because the everyone needs to hear this, and Iād keep coming back to this in my timeline.
Thanks Mario, for writing a piece āwithout much technical depthā but with depth nonetheless šš»
