Watch it →Shorelane is our open reliability testbed: public BigQuery data, dbt models, dashboards, planted traps, and ground truth anyone can inspect. Run the same discipline on the questions your company depends on.
Teams and benchmarks that reinforce the same lesson: a general-purpose agent with the right context already handles most analytics questions. Anthropic found auto-generated metric definitions were net-negative on evals. The hard part is everything around the agent.
Observability, evaluation, and governed context are one product because they are one loop.
Who asked what, which context each answer used, and where coverage is thin.
Analyst-confirmed ground truth, harvested from the questions your business already asks.
dbt commits, definition edits, model swaps. Drift is pinned to the change that caused it. CI for analytics.
The corrected context goes back in front of every agent, so the next answer is right for everyone.
Every corrected answer feeds the next observation.
Claude Code and Codex, the same question through the same Nodal context, landing on the same number. Swap agents without swapping truth.
