Agent Data Privacy & Secrets Management Protocol — SKILL.md for PII-Safe Agent Pipelines
$0.05 / access
SKILL.md protocol
GDPR · SOC2 · HIPAA
The agent-data-privacy-skill is a behavioral protocol for AI agents that touch sensitive data. It activates when agents process tool call responses containing PII, when credentials need scrubbing before session handoff, when compliance frameworks (GDPR, SOC2, HIPAA) require audit-ready data handling, or when secrets must be isolated across multi-agent pipelines. One $0.05 access call — one complete data privacy framework installed.
Agents leak data in ways humans don't anticipate. Tool call responses contain raw API output — API keys, email addresses, SSNs, health codes — none of which get scrubbed by default. This protocol installs systematic detection, redaction, and audit logging as agent behavior, not afterthought.
Protocol Overview — Core Phases
| Phase | What It Covers |
|---|
| PII Detection | Scan tool call responses for email, SSN, phone, DOB, health identifiers, financial account numbers; flag before processing or forwarding |
| Credential Scrubbing | Detect API keys, tokens, passwords, and secrets in responses; redact before logging, caching, or forwarding to sub-agents |
| Compliance Triggers | GDPR Article 5 data minimization — collect only what's needed; HIPAA minimum-necessary standard; SOC2 CC6 access control enforcement |
| x402 Payment Audit | Audit x402 payment flows for wallet address and transaction hash exposure; ensure payment metadata doesn't leak buyer identity beyond necessary disclosure |
| Secrets Isolation | Enforce secrets compartmentalization across agent delegation chains; sub-agents receive scoped credentials, not root access tokens |
| Retention & Deletion | Session-end data purge for ephemeral agents; configurable retention windows; structured deletion audit trail |
Protocol Excerpt
# Agent Data Privacy & Secrets Management Protocol
## Activation
Activate when: processing tool call responses that may contain PII or credentials;
before forwarding data to sub-agents or external APIs; at session end for credential
scrubbing; when compliance framework (GDPR/SOC2/HIPAA) is in scope for the workflow...
## Phase 1: PII Detection
### 1.1 Scan Tool Call Responses
- Patterns to flag: email (RFC 5321), SSN (###-##-####), phone (E.164),
DOB (ISO 8601 date in personal context), health codes (ICD-10, NDC),
financial account numbers (Luhn-valid 13–19 digit sequences)
- On detection: redact before logging; flag for minimization review;
do not forward raw PII to sub-agents unless explicitly scoped

Agent Use Cases
- Healthcare and fintech agents — install at pipeline entry to enforce HIPAA minimum-necessary and GDPR data minimization before any tool call response is processed or forwarded
- Multi-agent orchestration with secrets — scope credentials to sub-agents using the secrets isolation phase; root tokens never propagate down the delegation chain
- Compliance-gated deployments — SOC2 CC6 and GDPR Article 5 require documented access controls; this protocol generates the audit trail automatically
- x402 payment pipelines — audit payment metadata for wallet and transaction hash exposure; ensure buyer privacy beyond transaction settlement
- Session-boundary scrubbing — at handoff between agent sessions, run credential purge and PII redaction before state is persisted or passed to the next agent
Privacy and security stack — pairs naturally with:
Agent Security Audit ($0.05) — pre-deployment vulnerability scan; complements runtime privacy enforcement
Agent AI Governance ($0.03) — EU AI Act and GDPR decision auditability; governance layer above privacy enforcement
Agent Commerce Compliance ($0.05) — payment regulatory compliance; pairs with x402 audit phase
Data privacy without security audit leaves deployment-time gaps. Stack both for complete coverage.
