Agent 使用例
Claude Code / Codex CLI / Gemini CLI
Use psql only with non-interactive commands. Prefer structured output: csv, text, json. Ask before destructive operations. 安全メモ
- Prefer non-interactive usage and explicit output flags when an agent runs this command.
- Treat commands that deploy, delete, charge money, or mutate production data as approval-required.
- Record the exact command, output format, and scope before adding it to an agent workflow.
What agents can use it for
Query PostgreSQL databases and inspect schemas from terminal and agent workflows.
Agent usage rule
Prefer non-interactive commands, structured output, and approval gates for state-changing operations.
