Looking at the diagram, is this seriously a case of replacing basic functional concepts like "write to clickhouse" or "have we seen this before" to a model? could those be actual function calls in some language?

just seems wasteful all around. having an agent in the critical path when a regular expression (or similar) could do just seems odd. yeah haiku is cheap but re.match() is cheaper.

We're dealing with CI logs, produced by a variety of frameworks, languages, etc... And the tough ones to look into are e2e tests, with outputs from infrastructure. I wish a re.match() would be enough, but we often don't even know what to match in the first place.

We started to add deterministic matching on the patterns that the agent sees the most so we don't have to go through the whole thing (for example a flake on PostHog can occurs 100+ times during a day, you don't need to reinvestigate every time). But for new errors, it's tricky.
