Business question

How many paying customers did we have last month?

Interpretation to review

Count distinct customer accounts with a paid subscription at month-end.

  • Exclude trials and internal accounts
  • Use the last completed calendar month
Confirm before querying

Month-end status, or active at any point during the month?

The user reviews the business meaning. The agent runs the query.

§ 01 · The product in practice

Your team asks. Your data team sees the evidence.

People keep using their supported AI tools. Nodal brings the business context to those tools and gives your data team a way to review captured questions and test the answers.

What business users see

A question with its assumptions exposed.

“Paying customers” might mean subscriptions or accounts. Month-end accounts and accounts active at any point in the month can produce different answers. Review the interpretation before the agent queries your warehouse.

Keep model logic and column metadata in dbt. Add the dashboard-level business meaning your analyst confirms.

A question you can inspect and turn into a test.

Verification

Next step
Confirm a reference answer and save a test

A captured answer becomes a verified test only after its reference, time window, and tolerance are approved.

§ 02 · What your data team can do

See the questions. Check the answers. Keep the context shared.

Operate self-service analytics across connected workflows, with the agents and warehouse your team already uses.

  1. 01

    Observe real questions

    Review captured questions, the context used, and gaps in tested coverage.

  2. 02

    Turn the important ones into verified tests

    Compare important answers against analyst-approved references. Keep unchecked answers visible.

  3. 03

    Investigate regressions

    Rerun tested questions after dbt, definition, or model changes. Inspect which answers changed.

  4. 04

    Share context across agents

    Give supported agents the same maintained definitions. Keep technical metadata in dbt and add business context above it.

Review a question. Confirm the reference. Keep testing as your stack changes.

§ 03 · Shared context

Claude or Codex. The same business context.

Bring the definitions to the supported agents people already use. This side-by-side recording shows Claude Code and Codex answering through the same Nodal context. Agreement is useful; evaluation against an approved reference is how you check correctness.

No context layer yet? Start open source.

Nodal Context is optional and Apache-2.0. Already have business context your agents use? Keep it. If you do not, Nodal Context guides an AI interview on your schedule. Each confirmed business definition builds context and a test case together. Compare results with and without context to measure what helped. Keep technical metadata in dbt; add the business meaning above it. Model and warehouse usage are separate.
