Schema Builder

Build database schemas with SQL generation and relationship modeling. Use when designing databases.

Security Scan

The skill's files and runtime instructions are coherent with a local schema-generation tool: it generates SQL/ERD/migration/seed text and stores data under the user's home directory; it does not request credentials, install external code, or contact external endpoints.

Purpose & Capability

The declared purpose (database schema building) matches the included scripts: both scripts/schema.sh and scripts/script.sh produce schema designs, SQL, migrations, seeds and ER diagrams. Minor inconsistency: SKILL.md documents commands that call scripts/script.sh, while scripts/schema.sh contains additional commands (design, sql, migrate, seed, erd, etc.) that are not listed in SKILL.md. All functionality is still within the domain of schema generation.

Instruction Scope

SKILL.md instructs running scripts/script.sh and states data is stored in ~/.local/share/schema-builder. The scripts only create that directory and print/generated SQL/text; they do not read other system configuration or send data externally. Small issues: scripts/script.sh uses some unquoted shell variables (e.g., [ -f $2 ]) and echoes literal $2/$3 in single quotes (likely a bug), which are operational bugs but not secret-exfiltration behavior.

Install Mechanism

No install spec is present (instruction-only plus included scripts). No downloads, package installs, or archive extraction are performed by the skill bundle.

Credentials

The skill declares no required environment variables or credentials. The scripts use $HOME to create a local data directory (~/.local/share/schema-builder), which is proportional and expected for a local CLI-style tool.

Persistence & Privilege

always is false and the skill does not request elevated or persistent platform privileges. It only creates a directory within the user's home for storing its outputs; it does not modify other skills or system-wide config.

Assessment

This skill appears to be a local schema-generation utility and is internally consistent with its description. Before installing or permitting autonomous execution: 1) note that there are two scripts—script.sh (documented) and schema.sh (undocumented commands) — both generate text only and do not contact external servers; 2) the tool will create ~/.local/share/schema-builder for its outputs; 3) the shell scripts have minor quoting bugs (harmless but could produce incorrect output), so run them in an isolated environment (or inspect/patch them) if you plan to run on production systems; and 4) because the skill can be invoked autonomously by the agent, restrict autonomous execution if you are uncomfortable with any code running locally without supervision.
