dvcrn Client Data Management
This skill provides a secure, file-based client database for Greek accounting firms operating through OpenClaw. It manages all client master data, compliance history, document metadata, and relationship records while enforcing encryption, access control, and GDPR requirements for Greek business operations.
Setup
export OPENCLAW_DATA_DIR="/data"
which jq || sudo apt install jq
mkdir -p $OPENCLAW_DATA_DIR/clients
No external credentials required. Manages client records as JSON files in the local filesystem. Handles GDPR data lifecycle locally.
Core Philosophy
- File-Based Security: Encrypted JSON files managed through OpenClaw, no external database required
- Greek Business Focus: Built around AFM (VAT numbers), EFKA employer IDs, GEMI numbers, and Greek regulatory identifiers
- GDPR by Default: All personal data handled with consent tracking, retention policies, and deletion workflows
- Audit Everything: Every read, write, and delete of client data is logged with user identity and timestamp
- Assistant-Friendly: English interface with structured commands for non-technical accounting assistants
- Integration Hub: Client records link to all other skills — compliance, banking, EFKA, deadlines, OCR

Usage Examples
Example 1: Onboarding a New Client
Command: openclaw clients add --name "GAMMA IMPORT OE" --afm EL555444333 --legal-form OE --sector imports --gemi 098765432
System:
1. Validates AFM format (EL + 9 digits)
2. Creates /data/clients/EL555444333/ directory structure
3. Writes profile.json with provided data
4. Generates obligation template based on legal form + sector
5. Creates empty filings.json, contacts.json, documents/registry.json
6. Adds entry to /data/clients/_index.json
7. Logs creation event to audit trail
8. Output: "Client EL555444333 created. 4 recurring obligations configured. Assign accountant: openclaw clients update --afm EL555444333 --field accountant-assigned --value [username]"
Example 2: Monthly Compliance Check
Command: openclaw clients compliance-gaps --all-clients --period 2026-01
System:
1. Reads obligation templates for every active client
2. Cross-references against filings.json for period 2026-01
3. Identifies: 3 clients missing VAT submission, 1 client missing EFKA
4. Checks due dates — 2 are overdue, 2 due within 5 days
5. Output: Formatted table with client name, AFM, missing filing type, due date, assigned accountant
6. Optionally: openclaw clients compliance-gaps --all-clients --period 2026-01 --alert-assignees
Example 3: GDPR Data Export Request
Command: openclaw clients gdpr-export --afm EL123456789 --format json --output /data/gdpr-exports/
System:
1. Collects all data held: profile, contacts, filings, document registry, notes, audit log entries
2. Decrypts encrypted fields for export (requires senior_accountant role)
3. Formats as structured JSON with data categories labeled
4. Writes to /data/gdpr-exports/EL123456789_gdpr_export_20260218.json
5. Logs export event with requesting user and timestamp
6. Output: "GDPR export complete. File: EL123456789_gdpr_export_20260218.json (47 records, 12 categories)"
Example 4: Document Registration After OCR
Command: openclaw clients doc-register --afm EL123456789 --type invoice --file /data/ocr/output/accounting-ready/inv_2026_001.pdf --date 2026-02-10 --amount 3200.00 --vendor "DELTA SUPPLIES AE"
System:
1. Validates client exists and user has write access
2. Checks for duplicate (same file path not already registered)
3. Appends entry to /data/clients/EL123456789/documents/registry.json
4. Updates document count in client index
5. Logs registration to audit trail
6. Output: "Document registered: inv_2026_001.pdf → EL123456789. Registry now contains 23 documents for this client."

Safety & Compliance Guidelines
Data Handling Principles
- Never store raw bank credentials or passwords — only IBANs and account references
- All personal contact data (natural persons) is encrypted at rest
- Client financial history is retained for minimum 10 years per Greek law (Law 4308/2014)
- GDPR Article 17 deletion requests must preserve data required by Greek tax law for retention period
- Separation between clients is absolute — no cross-client data access or reporting without explicit multi-client permission
GDPR Retention Schedule
Retention_Periods:
financial_records: "10 years (Greek accounting law)"
tax_filings: "10 years (tax authority requirement)"
contact_data: "duration of engagement + 3 years"
audit_logs: "5 years"
gdpr_consent_records: "duration of processing + 3 years"
deleted_client_data: "immediately purged except legally mandated retention"
Remember: This skill is the single source of truth for all client master data. Every other skill references client records here. Data quality, completeness, and security in this skill directly determines the quality of all other skill outputs across the entire OpenClaw Greek Accounting system.
