Intro

Over the last few years, we have seen an immense boom in agentic coding tools, and while the applicability is often clear, workflow-wise there are different ways and flavours to do the job. At a high level, we’re talking about a trade-off among efficiency, effectiveness, autonomous vs. interactive ways to generate code, and, of course, security.

In this article I’ll focus on how to securely improve the efficiency of autonomous coding tools, like Codex*. That works as well for small-to-medium teams as for individuals.

*in the examples I’ll use Codex, but the same approach works for Claude Code, Gemini, OpenCode and other interchangeable agentic CLI tools. The only important detail is that you might need to change tool-specific flags and params.
