Designing Antigravity Agent Traces That Tell You Why It Failed — Observability in Practice
How to add OpenTelemetry spans to your own agent loop so a failure can be read in a few lines. Covers span structure, what to keep and drop in attributes, a failure_class taxonomy, a retry table, three dashboard views, cost attributes, and PII handling — with code that runs.
Assembling Observability with Antigravity × OpenTelemetry — Instrumentation, Sampling, Cardinality, and AI Anomaly Detection in Production
A record of running OpenTelemetry in production on a Node.js backend: measured instrumentation overhead, tail sampling configuration, avoiding cardinality explosion, and operating AI anomaly detection behind an approval gate.
Tracing Parallel Agents After the Fact: Observability with Structured Logs and Spans
Running multiple agents in parallel on the Antigravity 2.0 desktop makes it impossible to tell which one is doing what. I share an observability design that drops tangled print debugging for run_ids and spans you can trace afterward, with a solo-operator implementation and numbers.
