The record

Purpose: DbSketch is a command-line documentation generator that turns live database schemas into version-controlled schema documentation.
Database providers: It reads tables, columns, primary keys, and foreign keys from SQL Server, PostgreSQL, MySQL, and SQLite.
Output formats: It generates Graphviz DOT, Mermaid ER, or Markdown files wrapping diagram text in a fenced code block.
Configuration: DbSketch uses a YAML configuration file with one database connection and optional named diagram targets.
Multiple diagrams: One configuration can generate multiple focused diagrams with per-diagram output and renderer settings.
Comments: It can include native database comments where supported and apply YAML comment overrides.
Relationships: The DOT renderer preserves precise column-to-column foreign-key edges.
Use cases: The maker describes DbSketch as useful for repository documentation, CI, and compact schema context for AI coding assistants.
Distribution: DbSketch is distributed as the .NET tool DimonSmart.DbSketch, which installs the dbsketch command.
Requirement: The getting-started guide says to install the .NET 10 SDK before installing or running DbSketch.
Security and data handling: The documentation shows database connection strings supplied through configuration or environment-variable placeholders; it does not state a security certification or compliance claim.
License: The repository provides DbSketch under the MIT License.
Support: The maker welcomes issues and pull requests, including provider, renderer, and documentation improvements.
Intended users: The maker says DbSketch is for humans and AI coding assistants that need a compact, reviewable schema snapshot.
