Déjà vu is an always-on incident agent that decides who owns a production failure before it acts.
When an alert fires, a runner wakes the agent with the current time. It investigates through typed tools (logs, metrics, deploys, config changes, similar past incidents, vendor updates) instead of loading history into its prompt.
If we own the fault, it retrieves matching past incidents and runbooks, rejects decoys like an unrelated deploy, proposes or runs the fix, and refuses to close until recovery metrics hold for a full success window. It then saves a short, evidence-backed lesson, so when the same failure returns weeks later it diagnoses it in two checks without rereading old conversations.
Tinybird is the timeline and memory: alerts, logs, metrics, deploys, config changes, vendor snapshots, and the agent's own actions and lessons. Every query is limited to what was visible at that moment. Nimble reads third party vendor status pages and changelogs, and Tinybird stores and diffs each snapshot. Liquid handles fast triage and escalates to Claude for hard diagnoses.
