Beginor Agent Skills
A SQL-querying CLI plus a skill for database inspection in agents.
About
Ships Sharp-DB, a CLI tool for querying PostgreSQL, MySQL and SQLite and inspecting schema metadata (tables, views, columns, keys, constraints), bundled as a Claude Code skill so an agent can query databases and get results back as markdown tables with sane row caps. Multi-statement SQL files run in a transaction, and credentials can come from an environment variable so they stay off the command line. It is a small personal repo with two stars, and the source build needs the .NET 10 SDK; most users will just run the prebuilt binary. Sharp edges aside, it is one of the few skills that gives an agent direct read access to a live database.
What it can do
- SQL query execution with markdown-table results
- Schema and constraint inspection
- Multi-statement SQL files run in transactions
- Environment-variable credential handling
- Schema-aware filtering
