Known so far: deletes data; runs on someone else's infrastructure. - Floor 33, ceiling 57 (tier: unknown) - `unknown` means the floor and ceiling land in different bands — not measured enough to name one. It does not mean low. - This is impact, not likelihood. A high radius is not a defect: a filesystem server is supposed to write files. It is never part of the trust score. ## Machine-readable views of this entry - Signed JSON: https://forgeregistry.com/api/v1/packages/io.github.9thShini%2Fsmart-tools - Install plan: https://forgeregistry.com/api/v1/packages/io.github.9thShini%2Fsmart-tools/install-plan - Alternatives: https://forgeregistry.com/api/v1/alternatives/io.github.9thShini%2Fsmart-tools - HTML page: https://forgeregistry.com/registry/io.github.9thShini%2Fsmart-tools - MCP: POST https://forgeregistry.com/api/mcp → `forge_get_package` / `forge_install_plan` ## About this document Generated by Forge (https://forgeregistry.com) — a compact rendering of the same record served, signed, at the JSON URL above.
