Fix and improve this skill with Tessl
tessl review fix ./.claude/skills/add-deltachat/SKILL.mdW013: 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 modifying service unit files ("add `Environment=` lines to the systemd service unit or your launchd plist") and restarting systemd/launchd, which involves changing host service configuration and can alter the machine state.
W011: Third-party content exposure detected (indirect prompt injection risk).
What this means
The skill exposes the agent to untrusted, user-generated content from public third-party sources, creating a risk of indirect prompt injection. This includes browsing arbitrary URLs, reading social media posts or forum comments, and analyzing content from unknown websites.
Why it was flagged
SKILL’s required workflow wires DeltaChat DM/group messages via the DeltaChat adapter (messages delivered over email/IMAP) and those inbound messages are the outsider-authored free text the agent is meant to respond to.
