Very nice!

Kind of amazes me how many people bitch about agent performance but don't hook their guys up to Otel, crack Phoenix and get to work, but instead randomly tweak prompts in response to team vibes.

Good point. Also (tangent), I followed your profile link to https://sibylline.dev and am thoroughly impressed. Stoked to have found your treasure trove of repos and insights.

Don't play with them unless you're good at debugging alpha code (claude/codex can do it fine), I haven't ironed out env specific stuff or clarified the installation/usage, and I'm still doing UI polish/optimization passes (yay async simd rust). I'll do showy releases once I've got the tools one click install ready, in the meantime please feel free to drop an issue on any of my projects if there are features or questions you have.

aka let's spy on our devs more than we already are and give their pointy-haired bosses even more leverage to harass them with AI-usage KPI BS

Collecting detailed per-request traces and calculating user-specific metrics finer than a total cost feels about as intrusive as one of those periodic screenshot programs forced by really shitty remote jobs or freelancing contracts. It's pretty gross.
