  3. Privacy Risk Assessment with Scoring Matrix
  4. GDPR and CCPA/CPRA Alignment Checks
  5. Remediation Plan and Report Generation

What it can do on your machine

Read from SKILL.md and the folder at commit 54a7988. It shows what the files ask for, not the result of running them.

  • Tool permissions

    Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.

    From allowed-tools in the SKILL.md frontmatter.

  • Runs code

    Ships 1 file in scripts/ (Python), which the agent can run.

    From the folder's file list and the shell code blocks in SKILL.md.

  • Network

    No URLs in SKILL.md.

    From URLs in SKILL.md, links to its own repository left out.

  • Credentials

    Names no API keys, tokens, secrets or passwords.

    From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

Performing Privacy Impact Assessment loads about 2.6k tokens when it runs, and up to ~4.5k if it reads all its reference files. Until then it costs about 144 tokens; SKILL.md has 403 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~144
When it runs · the whole SKILL.md, loaded when a task matches
~2.6k
With references · SKILL.md plus every file in references/, read only if the agent opens them
~4.5k

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Safety

Auto-check passed

The automated check found no risky patterns in SKILL.md.

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); the scripts in this folder are not scanned.

Performing Privacy Impact Assessment

When to Use

  • When launching a new system, product, or processing activity that handles personal data
  • When conducting GDPR Article 35 Data Protection Impact Assessments (DPIAs)
  • When evaluating CCPA/CPRA compliance for data processing operations
  • When performing privacy risk assessments aligned to the NIST Privacy Framework
  • When mapping data flows across organizational boundaries and third-party processors
  • When building automated privacy governance and assessment pipelines
  • When preparing for regulatory audits or demonstrating accountability obligations

Prerequisites

  • Familiarity with GDPR, CCPA/CPRA, and NIST Privacy Framework concepts
  • Access to data processing inventories and system architecture documentation
  • Python 3.8+ with required dependencies installed
  • Appropriate authorization from the Data Protection Officer (DPO) or privacy team
  • Knowledge of organizational data flows and third-party processor relationships

Instructions

Phase 1: Data Inventory and Processing Activity Catalog

Build a complete inventory of personal data processing activities. Each record of processing activity (ROPA) entry must capture the data categories, legal basis, retention periods, and data subjects involved.

python
from agent import PrivacyImpactAssessmentEngine

engine = PrivacyImpactAssessmentEngine()

# Register a processing activity for assessment
activity = engine.register_processing_activity(
    name="Customer Analytics Platform",
    description="Collects browsing behavior and purchase history for personalization",
    data_controller="Acme Corp",
    data_processor="CloudAnalytics Inc",
    data_categories=["browsing_history", "purchase_records", "ip_address", "device_id"],
    data_subjects=["customers", "website_visitors"],
    legal_basis="consent",
    retention_period_days=730,
    cross_border_transfer=True,
    transfer_destinations=["US", "IN"],
    automated_decision_making=True,
)
print(f"Registered activity: {activity['activity_id']}")
Phase 2: Data Flow Mapping

Map all data flows from collection to deletion, identifying every touchpoint, transformation, and storage location. This reveals hidden privacy risks in data movement across systems.

python
# Build the data flow map
flow_map = engine.map_data_flows(
    activity_id=activity["activity_id"],
    flows=[
        {
            "stage": "collection",
            "source": "Web browser cookie + form submission",
            "destination": "CDN edge server",
            "data_elements": ["ip_address", "device_id", "browsing_history"],
            "encryption_in_transit": True,
            "protocol": "TLS 1.3",
        },
        {
            "stage": "processing",
            "source": "CDN edge server",
            "destination": "Analytics data warehouse (US-East)",
            "data_elements": ["browsing_history", "purchase_records", "device_id"],
            "encryption_in_transit": True,
            "encryption_at_rest": True,
            "protocol": "mTLS",
        },
        {
            "stage": "storage",
            "source": "Analytics data warehouse",
            "destination": "S3 encrypted bucket",
            "data_elements": ["browsing_history", "purchase_records"],
            "encryption_at_rest": True,
            "retention_days": 730,
            "access_controls": "IAM role-based, MFA required",
        },
        {
            "stage": "sharing",
            "source": "Analytics data warehouse",
            "destination": "Third-party ML provider (IN)",
            "data_elements": ["browsing_history", "purchase_records"],
            "encryption_in_transit": True,
            "data_processing_agreement": True,
            "cross_border": True,
        },
        {
            "stage": "deletion",
            "source": "S3 bucket + data warehouse",
            "destination": "Secure erasure",
            "method": "Cryptographic erasure + lifecycle policy",
            "verification": "Automated deletion audit log",
        },
    ],

Phase 3: Privacy Risk Assessment with Scoring Matrix

Apply a structured risk scoring methodology evaluating likelihood and impact across multiple privacy risk dimensions. The matrix aligns with both the NIST PRAM and ICO DPIA risk assessment approaches.

python
# Run the risk assessment
risk_report = engine.assess_privacy_risks(
    activity_id=activity["activity_id"],
    assessment_type="full_dpia",
)

# Display risk matrix results
for risk in risk_report["risks"]:
    print(f"[{risk['severity']}] {risk['category']}: {risk['description']}")
    print(f"  Likelihood: {risk['likelihood']}/5 | Impact: {risk['impact']}/5 | Score: {risk['risk_score']}/25")
    print(f"  Mitigation: {risk['recommended_mitigation']}")

Risk categories evaluated include:

  1. Data Minimization -- Excessive collection beyond stated purpose
  2. Purpose Limitation -- Secondary use without legal basis
  3. Cross-Border Transfer -- Transfers without adequate safeguards (SCCs, BCRs)
  4. Automated Decision Making -- Profiling without human oversight or appeal
  5. Data Subject Rights -- Inability to fulfill access/erasure/portability requests
  6. Third-Party Risk -- Processor compliance gaps, subprocessor chains
  7. Security Controls -- Encryption, access control, breach response gaps
  8. Retention -- Storing data beyond necessity or legal requirement
  9. Consent Management -- Invalid or ambiguous consent mechanisms
  10. Breach Notification -- Inability to detect and notify within 72 hours (GDPR)
Phase 4: GDPR and CCPA/CPRA Alignment Checks

Run automated compliance checks against specific regulatory requirements. The engine maps each processing activity against article-level GDPR obligations and CCPA/CPRA consumer rights requirements.

python
# GDPR compliance check
gdpr_report = engine.check_gdpr_compliance(activity_id=activity["activity_id"])
print(f"GDPR Score: {gdpr_report['compliance_score']}/100")
for finding in gdpr_report["findings"]:
    print(f"  [{finding['status']}] Art.{finding['article']}: {finding['description']}")

# CCPA/CPRA compliance check
ccpa_report = engine.check_ccpa_compliance(activity_id=activity["activity_id"])
print(f"CCPA Score: {ccpa_report['compliance_score']}/100")
for finding in ccpa_report["findings"]:
    print(f"  [{finding['status']}] Sec.{finding['section']}: {finding['description']}")
Phase 5: Remediation Plan and Report Generation

Generate a prioritized remediation plan with specific action items, responsible parties, deadlines, and generate the formal PIA/DPIA report document.

python
# Generate remediation plan
remediation = engine.generate_remediation_plan(
    activity_id=activity["activity_id"],
    risk_report=risk_report,
    gdpr_report=gdpr_report,
    ccpa_report=ccpa_report,
)

for item in remediation["action_items"]:
    print(f"[{item['priority']}] {item['action']}")
    print(f"  Owner: {item['owner']} | Deadline: {item['deadline']}")
    print(f"  Addresses: {', '.join(item['addresses_risks'])}")

# Generate formal DPIA report
engine.generate_dpia_report(
    activity_id=activity["activity_id"],
    output_path="dpia_report_customer_analytics.json",
    format="json",
)
print("[+] DPIA report generated")

Examples

Quick Screening Assessment

Determine whether a full DPIA is required using the ICO screening checklist:

python
engine = PrivacyImpactAssessmentEngine()

screening = engine.run_screening_checklist(
    uses_special_category_data=False,
    large_scale_processing=True,
    systematic_monitoring=True,
    automated_decision_making=True,
    cross_border_transfer=True,
    vulnerable_data_subjects=False,
    innovative_technology=True,
    denial_of_service_or_rights=False,
)
print(f"DPIA Required: {screening['dpia_required']}")
print(f"Triggers: {screening['triggers']}")
# Output: DPIA Required: True
# Triggers: ['large_scale_processing', 'systematic_monitoring',
#            'automated_decision_making', 'cross_border_transfer',
#            'innovative_technology']
Batch Assessment of Multiple Processing Activities
python
engine = PrivacyImpactAssessmentEngine()

activities = [
    {"name": "Email Marketing", "data_categories": ["email", "name"],
     "legal_basis": "consent", "cross_border_transfer": False},
    {"name": "HR Analytics", "data_categories": ["employee_id", "performance_scores",
     "health_data"], "legal_basis": "legitimate_interest", "cross_border_transfer": True},
    {"name": "Fraud Detection", "data_categories": ["transaction_data", "ip_address",
     "device_fingerprint"], "legal_basis": "legitimate_interest",
     "automated_decision_making": True, "cross_border_transfer": False},
]

for act_def in activities:
    activity = engine.register_processing_activity(**act_def)
    risk = engine.assess_privacy_risks(activity_id=activity["activity_id"])
    print(f"{act_def['name']}: Overall Risk={risk['overall_risk_level']} "
          f"({risk['risk_count_by_severity']})")
NIST Privacy Framework Profile Mapping
python
engine = PrivacyImpactAssessmentEngine()

profile = engine.generate_nist_privacy_profile(
    activity_id=activity["activity_id"],
    target_tier="tier_3",  # Repeatable
)

for function_id, outcomes in profile["functions"].items():
    print(f"\n{function_id}:")
    for outcome in outcomes:
        status = "PASS" if outcome["implemented"] else "GAP"
        print(f"  [{status}] {outcome['subcategory']}: {outcome['description']}")
