A developer shared pg-dry-run on Hacker News, a tool that lets AI agents preview Postgres writes before committing them using xmin checks. It targets the practical problem of letting agents run safely against production databases. Interest so far is minimal, with low engagement on the launch post.
pg-dry-run is an MIT-licensed TypeScript library that previews PostgreSQL INSERT, UPDATE, and DELETE statements inside a read-only transaction before they are applied. It targets developers building AI agents that write to databases, where reviewing generated SQL is insufficient because a statement's actual effect depends on current database state. It returns a JSON proposal showing affected rows, before/after values, and cascade effects so writes can be reviewed safely.

A developer whose AI agent nearly ran a destructive query through a supposedly read-only Postgres login found that role inheritance, table ownership, and indirect grants made the login more powerful than intended. They built agent-db-scan, an open-source tool that audits a Postgres connection's effective privileges. It matters to anyone giving database credentials to agents.

Agent_acid is a tool that provides ACID-like transaction guarantees and dry-run guardrails for AI agents, enabling safe rollbacks of agent actions. It uses LLMs to plan and execute agent workflows while ensuring atomicity, consistency, isolation, and durability, solving the problem of unreliable agent execution for developers building autonomous systems.

Holdline is a benchmark designed to test the effectiveness of AI agent guardrails. It caught a vulnerability in the creator's own plugin, demonstrating its utility. It helps developers evaluate and improve safety measures for AI agents.
