/cs:cdo-review <plan> — Decision-driven Chief Data Officer interrogation of any plan that touches training data, data architecture, data productization, or data team hiring. Use when validating training-data rights before model work, choosing warehouse vs lakehouse vs mesh, or valuing data assets for productization or M&A.From its SKILL.md

  • no licenseNo license file was found in the repository. Code published without one is not open source by default, so using it at work is a question for whoever answers licensing questions where you are.

/cs:cdo-review — CDO Forcing Questions

Command: /cs:cdo-review <plan>

The decision-driven CDO pressure-tests any plan that touches data strategy. Six questions before any commitment to a data architecture, AI training run, data productization, or data team hire.

When to Run

  • Before approving any new ML model training run that uses customer data
  • Before signing a multi-year data-infrastructure SaaS contract (Snowflake, Databricks, Fivetran)
  • Before productizing any customer data (benchmark report, embedding endpoint, license)
  • Before a major data team hire (head of data, CDO, data PM, ML engineer)
  • Before M&A diligence — yours or theirs
  • When the founder uses the word "monetize" near "data"

The Six CDO Questions

1. What decision does this data drive?

If no decision is unblocked, why are we collecting / training on / productizing it?

  • "We might need it later" is not a decision.
  • "It feels like a moat" is not a decision.
  • A real answer names a specific business call that requires this data.

2. What's the consent provenance for every source?

For each data source: origin, consent flow, data class, intended use.

  • 1st-party-TOS-only is weaker than 1st-party-explicit-opt-in.
  • Bundled TOS doesn't cover material new purposes (training on PII for foundation models).
  • Run ai_training_data_audit.py if there's any AI use case in scope.

3. Who consumes this internally — and how many distinct functional domains?

Drives the centralize-vs-embed and warehouse-vs-mesh decisions.

  • <5 consumers: warehouse-only.
  • 5-25 consumers: lakehouse.
  • 25+ consumers + federated culture: mesh.
  • Premature architecture choice is the #1 cause of data-team burnout.

4. What's the M&A diligence impact?

If an acquirer asks about this data corpus tomorrow, are we ready?

  • Is there a documented anonymization process?
  • What % of customers have MSA carve-outs?
  • Are training-data provenance logs current?
  • Run data_asset_valuator.py quarterly.

5. Can the model / decision / report be retrained / re-run / re-published without this source?

Tests how much you depend on a specific data source.

  • If yes → low blast radius; you can change consent posture later.
  • If no → high blast radius; you've structurally committed to the source. Vet harder.

6. What role unblocks this — and is it the right next hire?

Wrong hire (data scientist) when right answer (analytics engineer) is a 12-month productivity loss.

  • Map the decision being unblocked to the specific role.
  • Confirm prerequisite roles are in place (data engineer before ML engineer, analyst before data scientist).

- Kill criteria: <when to revisit>

## Asset Value (if applicable)
- Strategic value: X/10 | Moat: STRONG / MEDIUM / WEAK
- M&A multiplier: X.Xx – X.Xx ARR
- Recommended productization path: <name>

## Org (if applicable)
