The Agent Skills Directory

[COMMAND_EXECUTION]: The skill is configured to use the Bash tool restricted to nginx and systemctl commands. These are necessary for the skill's primary purpose of testing configurations (nginx -t) and managing the web server service (systemctl reload nginx). These operations are scoped appropriately for a DevOps-focused skill.
[PERSISTENCE]: The reference material provides standard documentation for setting up a cron job to handle automatic SSL certificate renewal via certbot. This is a routine administrative task and does not represent a malicious persistence mechanism.
[INDIRECT_PROMPT_INJECTION]: The skill possesses a data ingestion surface by processing user-provided Nginx configuration requirements. It has the capability to write files and execute server commands. However, the skill provides clear boundary instructions, such as mandating configuration testing (nginx -t) before reloading, which serves as a safety check against malformed or malicious configurations.
