The Agent Skills Directory

[SAFE]: The skill provides legitimate technical instructions for MariaDB administration, including SQL queries for diagnosis and correction of encoding issues. All external links point to official MariaDB documentation.
[COMMAND_EXECUTION]: The skill includes instructions for executing shell commands such as mariadb-dump and mariadb for database backup and restoration. These are standard administrative tools and are used here for their intended purpose in a safe manner.
[INDIRECT_PROMPT_INJECTION]: The skill interacts with database metadata, creating a theoretical injection surface. 1. Ingestion points: information_schema.COLUMNS and information_schema.TABLES (Example 11, 12, 13). 2. Boundary markers: None mentioned for metadata ingestion. 3. Capability inventory: ALTER TABLE and SET GLOBAL SQL commands, plus mariadb-dump shell execution. 4. Sanitization: Basic backtick escaping is used in generated SQL strings for table names.
[METADATA_POISONING]: The author name in SKILL.md (OpenAEC-Foundation) differs from the provided developer name (impertio-studio). This metadata inconsistency is noted but appears to be a naming variation rather than a deceptive attempt.
