osss tools

Open-source Rust tooling for declarative PostgreSQL schema management and testing, and for agent-driven multi-repo workflows.

PostgreSQL tools

A family of four composable Rust tools for managing and testing PostgreSQL schemas declaratively.

pgsmpostgres_schema_management

The engine: diffs and verifies a declarative schema repository against a live database.
pgstdpostgres_schema_to_directory

Extracts a live database into a per-schema, per-object-type file tree.
pgsfpostgres_sql_formatter

Formats SQL to a consistent style guide. Available as a CLI and a library.
pgtpostgres_test

SQL-native database tests returning a typed composite result — a pgTAP alternative, no TAP or Perl.

The tools compose: pgsm uses pgstd to export and pgsf to format, and can delegate test execution to pgt.

Workflow tools

The toolbox behind an agent-friendly, multi-repo workspace layout.

wtworktree

A per-branch git-worktree CLI — every checkout is created and torn down on a branch-named layout. Rust.
agent_workspace_template

A skeleton for a multi-repo agent-workspace meta-repo: per-project briefs, path-triggered context loading, and wt-managed checkouts.
