Technical Analysis
The reference material directs users to upload renovation quote photographs to external AI services and renovation applications and to discuss quote information through public or semi-public social channels. It does not instruct users to redact sensitive information, obtain consent from affected parties, assess service retention policies, or restrict the information disclosed.
Renovation quotes can contain personally identifiable and financially sensitive information, including customer names, telephone numbers, home addresses, apartment numbers, signatures, contractor identities, pricing details, account information, QR codes, and document identifiers. Uploading an unredacted image transfers this information outside the local Skill environment to services with separate access, retention, training, and redistribution policies.
The disclosure is avoidable because the Skill is designed to analyze documents supplied within its current environment. Recommending external uploads without a privacy warning creates an unnecessary data-exposure path.

Remediation Suggestions
- Remove recommendations to share quote documents in public or semi-public discussion groups.
- Prefer analysis performed within the local Skill environment whenever possible.
- If use of an external service remains optional, add an explicit warning requiring users to redact:
- Names and telephone numbers.
- Full addresses, community names, building numbers, and apartment numbers.
- Signatures and identity-document information.
- Bank details, payment information, and QR codes.
- Contract, customer, and document identifiers.
- Contractor contact information and other third-party personal data.
- Require users to obtain consent before disclosing information belonging to contractors, household members, or other affected parties.
- Advise users to review the external service's data-retention, model-training, sharing, deletion, and privacy policies before uploading documents.
- Recommend sharing only the minimum fields required for analysis, such as item descriptions, quantities, unit prices, totals, material specifications, and construction methods.
- Where practical, provide a local redaction checklist or document-sanitization workflow before any external disclosure.
