pii-audit

pii-audit is a skill for Claude Code, Codex from AltimateAI/altimate-code. It costs 46 tokens per session (934 once invoked), scanned A, original, MIT.

A read-only database privacy reviewer that identifies personally identifiable information (PII), such as email addresses, phone numbers, names, health records, or credit card numbers, in schemas and queries.

In plain words
What is it for?
Use it to create a PII inventory, classify database columns, check a query for exposed personal data, or review dbt models for privacy leaks.
Why use it?
It shows where sensitive data exists and whether a query exposes it, supporting privacy reviews for laws and standards such as GDPR, CCPA, and HIPAA.

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

pii-audit 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 4d 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.

PII Audit

Requirements

Agent: any (read-only analysis) Tools used: altimate_core_classify_pii, altimate_core_query_pii, schema_detect_pii, schema_inspect, read, glob

When to Use This Skill

Use when the user wants to:

  • Scan a database schema for PII columns (SSN, email, phone, name, address, credit card, IP)
  • Check if a specific query exposes PII data
  • Audit dbt models for PII leakage before production deployment
  • Generate a PII inventory for compliance (GDPR, CCPA, HIPAA)

Do NOT use for:

  • SQL injection scanning -> use sql-review
  • General SQL quality checks -> use sql-review
  • Access control auditing -> finops role tools in cost-report

Workflow

1. Classify Schema for PII

Option A — From schema YAML/JSON:

altimate_core_classify_pii(schema_context: <schema_object>)

Analyzes column names, types, and patterns to detect PII categories:

  • Direct identifiers: SSN, email, phone, full name, credit card number
  • Quasi-identifiers: Date of birth, zip code, IP address, device ID
  • Sensitive data: Salary, health records, religious affiliation

Option B — From warehouse connection:

First index the schema, inspect it, then classify:

schema_index(warehouse: <name>)
schema_inspect(warehouse: <name>, database: <db>, schema: <schema>, table: <table>)
schema_detect_pii(warehouse: <name>)

schema_detect_pii scans all indexed columns using pattern matching against the schema cache (requires schema_index to have been run).

2. Check Query PII Exposure

For each query or dbt model, check which PII columns it accesses:

altimate_core_query_pii(sql: <sql>, schema_context: <schema_object>)

Returns:

  • Which PII-classified columns are selected, filtered, or joined on
  • Risk level per column (HIGH for direct identifiers, MEDIUM for quasi-identifiers)
  • Whether PII is exposed in the output (SELECT) vs only used internally (WHERE/JOIN)

3. Audit dbt Models (Batch)

For a full project audit:

glob models/**/*.sql

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.

pii-audit is a skill published in the GitHub repository AltimateAI/altimate-code (803 stars, last pushed 4d ago), licensed MIT. It adds 46 tokens to every session and 934 once invoked, about $0.0002 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
