data-quality-frameworks

data-quality-frameworks is a skill for Claude Code, Codex from mattmre/EVOKORE-MCP-PUBLIC. It costs 37 tokens per session (3,587 once invoked), scanned A, a copy of data-quality-frameworks, MIT.

A guide to checking whether data is complete, unique, valid, accurate, consistent, and current. It uses Great Expectations, dbt tests, and data contracts to define and enforce those checks.

In plain words
What is it for?
Use it to validate data pipelines, create Great Expectations or dbt checks, define data contracts, monitor quality measurements, and run validation in CI/CD.
Why use it?
It helps catch bad or changed data before it causes failures or misleading reports. Automated checks can also make expectations between teams and data pipelines explicit.

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-frameworks 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 6d 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.

Data Quality Frameworks

Production patterns for implementing data quality with Great Expectations, dbt tests, and data contracts to ensure reliable data pipelines.

When to Use This Skill

  • Implementing data quality checks in pipelines
  • Setting up Great Expectations validation
  • Building comprehensive dbt test suites
  • Establishing data contracts between teams
  • Monitoring data quality metrics
  • Automating data validation in CI/CD

Core Concepts

1. Data Quality Dimensions

Dimension Description Example Check
Completeness No missing values expect_column_values_to_not_be_null
Uniqueness No duplicates expect_column_values_to_be_unique
Validity Values in expected range expect_column_values_to_be_in_set
Accuracy Data matches reality Cross-reference validation
Consistency No contradictions expect_column_pair_values_A_to_be_greater_than_B
Timeliness Data is recent expect_column_max_to_be_between

2. Testing Pyramid for Data

Quick Start

Great Expectations Setup

# Install
pip install great_expectations

# Initialize project
great_expectations init

# Create datasource
great_expectations datasource new
# great_expectations/checkpoints/daily_validation.yml
import great_expectations as gx

# Create context
context = gx.get_context()

# Create expectation suite
suite = context.add_expectation_suite("orders_suite")

# Add expectations
suite.add_expectation(
    gx.expectations.ExpectColumnValuesToNotBeNull(column="order_id")
)
suite.add_expectation(
    gx.expectations.ExpectColumnValuesToBeUnique(column="order_id")
)

# Validate
results = context.run_checkpoint(checkpoint_name="daily_orders")

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.
