What cdo-review does

The skill runs plans through six Chief Data Officer questions. It checks consent provenance and blast radius if a source is lost. Internal consumer counts dictate the stack: under 5 consumers calls for a warehouse, 5 to 25 suggests a lakehouse, and 25 or more suggests a mesh.

Bundled Python scripts handle the calculations. The command runs ai_training_data_audit.py on training sources and data_product_strategy_picker.py for stack choices. For corpus valuation, it calls data_asset_valuator.py. Every review outputs a verdict: SHIP, SHARPEN, or BLOCK.

The scripts expect JSON files like sources.json or corpus.json. Install this before committing to contracts with Snowflake or Databricks. Skip it if you have no ML plans.

What it helps with

  • audit consent provenance before running ML training on customer data
  • choose between warehouse, lakehouse, and mesh based on consumer count
  • value data assets and verify anonymization before M&A diligence
  • verify hiring sequences like data engineer before ML engineer

Example prompts for the agent

  • /c-level-agents:cdo-review ml-training-spec.md
  • /c-level-agents:cdo-review Review our plan to switch from Snowflake to lakehouse
  • /c-level-agents:cdo-review Evaluate data monetization plan for benchmark reports

What does cdo-review do?

It interrogates plans involving data infrastructure, AI training datasets, hiring, and data monetization against six CDO questions. The output gives a SHIP, SHARPEN, or BLOCK verdict with three action items.

What scripts does cdo-review execute?

It runs ai_training_data_audit.py for training data, data_product_strategy_picker.py for architecture decisions, and data_asset_valuator.py for asset valuation. Running these checks requires Python and JSON input files.

# /c-level-agents:cdo-review — CDO Forcing Questions

**Command:** `/c-level-agents: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).

## Workflow

```bash
# 1. AI training audit (if any ML / AI use case)
python ${CLAUDE_PLUGIN_ROOT}/vendor/c-level-advisor/chief-data-officer-advisor/scripts/ai_training_data_audit.py sources.json

# 2. Architecture decision (if changing the stack)
python ${CLAUDE_PLUGIN_ROOT}/vendor/c-level-advisor/chief-data-officer-advisor/scripts/data_product_strategy_picker.py profile.json

# 3. Data asset valuation (if productizing or pre-M&A)
python ${CLAUDE_PLUGIN_ROOT}/vendor/c-level-advisor/chief-data-officer-advisor/scripts/data_asset_valuator.py corpus.json
```
