Engineering notes
from the strata.
Posts on agent architecture, ServiceNow internals, why we open-sourced what we open-sourced, and the mistakes we made along the way. Slow cadence — only when we have something specific to say.
Open by default: why every Serac prompt is public
We publish every prompt, planner trace, and connector. Here's the engineering case for it — and why proprietary 'magic' is a tax we refuse to pay.
Human-in-the-loop is not a setting
Most agentic platforms bolt approvals on as an afterthought. Serac is built on the inversion: autonomy is opt-in, step by step.
What 'platform-aware' means for ServiceNow agents
Generic REST clients break on ServiceNow within a week. Here's the schema work that makes Serac different — and why it's not something you can shortcut.
Self-host, BYO LLM, BYO vault: portable by construction
Vendor lock-in is a design failure. Walking through every place Serac could have created lock-in — and why we refused at each step.
Hiring builders, not vendors
We have five open roles and one rule: ship something we can run before the call. The thinking behind how Serac Labs hires.
