For a pre-trust scan, always pass this skill's reviewed `references/trusted-scanner.toml` by absolute path and do not use a target-owned baseline. +- Treat scanner findings as security evidence, not a guarantee that a package is safe. +- Ask before installing `plugin-scanner` if the command is not already available. + +## Workflow + +### 1.
