testland/mailpit-testing

Configures and runs Mailpit - modern dev-mailbox server for SMTP testing with built-in REST API for assertions; default SMTP `1025` + Web UI `8025`; ships single static binary or multi-architecture Docker images; features Chaos mode (configurable SMTP errors for resilience testing), message tagging (manual + auto via filters and plus-addressing), search filters. Use when the user develops email-sending code locally / in CI and needs SMTP capture with programmatic test assertions, or when migrating from MailHog (which Mailpit succeeds).

Medium

W013: Attempt to modify system services in skill instructions.

What this means

The skill prompts the agent to compromise the security or integrity of the user’s machine by modifying system-level services or configurations, such as obtaining elevated privileges, altering startup scripts, or changing system-wide settings.

Why it was flagged

The skill explicitly instructs running a remote install script with sudo (e.g. "sudo sh < <(curl ... install.sh)"), which asks for elevated privileges and would modify system files and state.

1 low severity finding. Worth noting, but not necessarily harmful.

W012: Unverifiable external dependency detected (runtime URL that controls agent).

What this means

The skill fetches instructions or code from an external URL at runtime, and the fetched content directly controls the agent’s prompts or executes code. This dynamic dependency allows the external source to modify the agent’s behavior without any changes to the skill itself.

Why it was flagged

The SKILL.md includes an install step that runs "sudo sh < <(curl -sL https://raw.githubusercontent.com/axllent/mailpit/develop/install.sh)" which fetches and directly executes remote code at runtime from https://raw.githubusercontent.com/axllent/mailpit/develop/install.sh.
