Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

data-quality scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 2d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

What it actually says

Data Quality Command

Generate quality rules, expectations, and test suites for your data

Usage

/data-quality <model-or-description>

Examples

/data-quality models/staging/stg_orders.sql
/data-quality "Quality checks for customer dimension table"
/data-quality models/marts/

What This Command Does

  1. Invokes the data-quality-analyst agent
  2. Reads model SQL or description to understand schema and business rules
  3. Loads KB patterns from data-quality and dbt domains
  4. Generates:
    • Great Expectations suite with expectations
    • dbt schema YAML with tests
    • Custom data quality SQL assertions
    • Freshness and completeness checks

Agent Delegation

Agent Role
data-quality-analyst Primary — GE suites, quality rules, observability
dbt-specialist Escalation — when tests need dbt YAML format
data-contracts-engineer Escalation — when SLAs need formal contracts

KB Domains Used

  • data-quality — Great Expectations, Soda, observability patterns
  • dbt — dbt tests, schema YAML, custom generic tests
  • data-modeling — constraint patterns, referential integrity

Output

The agent generates test definitions in your preferred format (GE, dbt, SQL) with severity classification.

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
