Bearer privacy

Skill mguttmann/code-audit-suite/skills/bearer-privacy

This skill should be used when the user asks to "run Bearer", "scan for PII", "Datenschutz prüfen", "DSGVO/GDPR check", "find sensitive data flows", "PII/PHI scan", "privacy risk", or wants to know where personal/health data flows through the code. Runs Bearer in Docker to classify and trace sensitive data, processed directly in Claude Code.From its SKILL.md

Bearer Privacy

Purpose

Bearer adds a dimension orthogonal to SonarQube and the pure taint engines: it classifies 120+ sensitive data types (PII/PHI) and traces where that data flows — a privacy/GDPR (DSGVO) lens, not just vulnerability classes. It answers "does personal data reach a log, a third-party API, or an unencrypted store?", which neither SonarQube nor a generic SAST tool reports.

This is unique coverage, not a duplicate of any other skill.

Core Workflow (drive to zero)

Scan:

~/.claude/skills/bearer-privacy/scripts/scan.sh [TARGET_DIR]

For each finding, fix the data-handling root cause: stop logging the sensitive field, encrypt it at rest/in transit, mask/redact it before it leaves the system, or remove the unnecessary collection. Bearer maps findings to data categories (e.g. "Personal Data", "Sensitive Data") and rules (e.g. data sent to third party, stored unencrypted, leaked in logs).
Re-run until the scan exits 0.

Notes

Default scanner is sast (security + privacy rules). BEARER_SCANNER=secrets runs Bearer's secret detection instead — prefer the dedicated secrets-scan skill for that.
Adjust the failing threshold with BEARER_SEVERITY (default critical,high); review medium/low informationally.
JSON/SARIF output for parsing: BEARER_FORMAT=json scan.sh [DIR].
Bearer's CLI is free for internal use (Elastic License 2.0); only the hosted management plane is commercial. This skill uses the CLI only.

Resources

scripts/scan.sh — runs bearer scan against a directory, exit 1 on findings at/above the severity threshold. Env: BEARER_FORMAT, BEARER_SCANNER, BEARER_SEVERITY.
