Billclaw

Security checks across malware telemetry and agentic risk

Overview

BillClaw is a clearly disclosed finance skill that handles sensitive bank and Gmail data, but its access is purpose-aligned and user-directed.

Install only if you are comfortable letting the @firela BillClaw packages handle bank and Gmail-related data. Grant only the Plaid, GoCardless, or Gmail access you actually need, verify the npm package/source provenance if this is high-trust financial use, and protect or delete the local ~/.firela/billclaw/ data when appropriate.

Finding
This skill handles highly sensitive financial and email data and integrates with third-party providers, but the user-facing description emphasizes safety and local-first behavior more than the privacy and data-sharing implications. Users may underestimate that bank metadata, transaction data, email contents, OAuth tokens, and related identifiers could be accessed and transmitted during normal use.
