AI Data Validation Skill: Ensure Data Quality & Integrity

AI Data Validation Skill: Ensure Data Quality & Integrity

The AI Data Validation Skill performs a comprehensive, read-only inspection of data to ensure its quality and integrity within a project’s environment, producing a detailed validation report. It analyses record counts, NULL rates, value distribution, uniqueness, referential integrity, format validity, and provides sampled evidence rows. This skill is invoked through specific user requests and integrated GitHub issue verification triggers, operating solely in read-only mode.

What this skill does

• Inspects data for correctness based on the project’s test fixtures or an explicitly configured connection, never using production sources.
• Generates a validation report that includes concrete measures such as record counts, NULL rates, and value distributions.
• Reports findings based on quantifiable data and sampled rows, stating expected versus actual values along with evidence.
• Can be triggered by user commands or as part of GitHub issue resolution steps but never modifies data or code.

Who it is for

• Developers and data engineers working within environments supported by AI agents such as Claude Code, Cursor, and Codex.
• QA teams seeking to assure data quality and integrity in test environments.

Use cases

• Conducting scheduled validation checks to ensure ongoing data quality in development environments.
• Assisting quality assurance processes by verifying data-related changes during code reviews on GitHub.
• Responding to specific data quality requests by team members to support informed decision-making in project developments.

Technical details

• Category: AI agent skill compatible with Claude Code, Cursor, and Codex.
• Triggers in response to specific requests including user inputs or during GitHub issue resolution.
• Operates exclusively in read-only mode, ensuring no data manipulation occurs.
• Outputs findings to session by default; files are generated only when explicitly asked for by the user.
