copilot-instructions: Instructions file for GitHub Copilot

.github/instructions/data-privacy-compliance.instructions.md

copilot-instructions data-privacy-compliance.instructions.md is an instructions file for GitHub Copilot from ThiagoGuislotti/copilot-instructions. It costs 566 tokens per session, scanned A, original, MIT.

A baseline for privacy and compliance when an application handles personal data. It covers data inventories, classification, minimization, consent, legal basis, pseudonymization, access control, and separation of data.

In plain words
What is it for?
Use it when designing APIs, frontends, backends, or databases that process personal data, especially when defining retention, consent records, permissions, and downstream data handling.
Why use it?
It helps teams identify privacy risks early and avoid collecting, retaining, or sharing personal data without a clear purpose and control.

Instructions file for GitHub Copilot

Written for GitHub Copilot: a Copilot instructions file.

This is ThiagoGuislotti/copilot-instructions's own configuration. It tells GitHub Copilot how to work on copilot-instructions itself, so it is not a mod to install elsewhere. Copy it as a starting point and replace the rules that are about this project. Everything copilot-instructions configures →

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

copilot-instructions data-privacy-compliance.instructions.md 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 7d 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.

The opening of the file, as written. The whole thing — 57 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Data Privacy and Compliance Baseline

  • Use this instruction for privacy-by-design decisions across API, frontend, backend, and database layers.
  • Treat personal data handling as an explicit architecture concern, not only a legal review step.

Scope and Governance

  • Maintain a current data inventory with owner, purpose, sensitivity class, and retention policy.
  • Classify data at minimum as public, internal, confidential, and restricted.
  • Define accountability for each processing activity and audit ownership.

Privacy by Design

  • Apply data minimization; collect and retain only what is necessary for the declared purpose.
  • Enforce purpose limitation; prevent uncontrolled reuse of collected data.
  • Prefer pseudonymization or tokenization for identifiers in non-core processing flows.
  • Separate operational identifiers from personal identifiers whenever feasible.
  • Record legal basis and consent state for processing operations that require it.
  • Keep auditable records of consent capture, updates, and withdrawal events.
  • Propagate consent constraints to downstream systems and derived datasets.

Access Control and Segregation

  • Enforce least privilege access to personal data by role and business purpose.
  • Segment privileged access paths and require elevated controls for sensitive datasets.
  • Protect multi-tenant boundaries with strict tenant-scoped access checks.

Data Protection Controls

  • Encrypt personal and sensitive data in transit and at rest.
  • Use managed key lifecycle controls including rotation and access auditing.
  • Mask or redact personal data in logs, telemetry, and non-production datasets.
  • Prohibit secrets and personal data leakage in error messages and debug outputs.

Retention, Deletion, and Archival

  • Define retention schedules per data class and enforce automated expiration where feasible.
  • Implement deletion workflows that include primary stores, replicas, caches, and derived datasets.
  • Validate backup and archival deletion semantics against retention and legal constraints.
  • Maintain verifiable evidence of deletion and retention policy execution.

What this file has done since we first saw it

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.
