--- name: gdpr-data-handling description: Practical implementation guide for GDPR-oriented data-processing design, consent management, and privacy controls. metadata: aas-risk: critical aas-source: community aas-date-added: '2026-02-27' --- # GDPR Data Handling Practical implementation guide for GDPR-oriented data-processing design, consent management, and privacy controls. ## Use this skill when - Building systems that process EU personal data - Implementing consent management - Handling data subject requests (DSRs) - Conducting GDPR compliance reviews - Designing privacy-first architectures - Creating data processing agreements ## Do not use this skill when - The task is unrelated to gdpr data handling - You need a different domain or tool outside this scope ## Instructions - Clarify goals, constraints, and required inputs. - Apply relevant best practices and validate outcomes. - Provide actionable steps and verification. - If detailed examples are required, open `resources/implementation-playbook.md`. ## Resources - `resources/implementation-playbook.md` for detailed patterns and examples. ## Limitations - Use this skill only when the task clearly matches the scope described above. - Do not treat the output as a substitute for environment-specific validation, testing, or expert review. - Stop and ask for clarification if required inputs, permissions, safety boundaries, or success criteria are missing. The playbook is partial application scaffolding, not a compliance certification. Database/auth/event/notification helpers and calendar-month deadline computation must be implemented and tested before use; a request-supplied `verified` boolean is not identity proof. Authenticate/authorize the handler and subject ownership before any export/deletion, filter third-party data and report partial-source failures without marking complete. Portability has specific legal scope and is not identical to access. Retention periods and consent-log fields are illustrative, not universal legal minima; justify collection and apply legal holds/backups/restore handling. Pseudonymisation/removing IDs does not establish anonymity. Breach risk flags require a documented competent assessment, with the controller clock tied to actual awareness; high-risk subject notification is without undue delay and has legal exceptions. Do not dispatch notices or delete data outside the authorized incident/request procedure.
