Maintain Observability Surfaces

Companion Guidance

Use karpathy-guidelines alongside this skill for implementation or review work. Keep changes scoped, surface assumptions, and define focused validation before editing.

Use this skill when changing event fields, exporter behavior, subscriber config, or binding parity for ATIF, OpenTelemetry, or OpenInference.

Surfaces To Keep In Sync

Core event model and emitted fields
crates/core/src/observability/atif.rs
crates/core/src/observability/otel.rs
crates/core/src/observability/openinference.rs
FFI and binding-native wrappers where the config or lifecycle is exposed
Python, Go, and Node.js config objects and subscriber/exporter methods
Docs under docs/about/concepts/subscribers.md and docs/export-observability-data/about.md

Design Checklist

Is this an event-model change, exporter-config change, or lifecycle change?
Do all bindings expose the same logical knobs and semantics?
Are mark events, start/end events, and orphan cases still handled correctly?
Do examples and docs reflect the same lifecycle: create, register, run, deregister, flush, shutdown?
Are span or trajectory fields still derived from the intended event data?

Validation

Run the affected Rust crate tests plus just test-rust if event fields changed.
Run just test-python, just test-go, and just test-node when binding-native config or lifecycle changed.
Update docs and examples in the same branch.
