awesome-codex-subagents

This is a curated collection of subagents for OpenAI's Codex CLI, now past 170 entries across more than a dozen categories. Picture an app store of pre-built specialists: each subagent is a config file tuned for one job, testing, documentation, security review, database migration, and dozens more.

You don't build these yourself. You browse the list, grab the ones that fit your workflow, and drop them into your Codex agents directory. They use Codex's native TOML format with Codex-specific fields like reasoning effort and sandbox mode. Codex does not spawn them automatically, you delegate to them explicitly.

The collection is free. You pay for Codex usage through your OpenAI account. It is community-maintained and still growing, so the catalog keeps expanding.

The catch: this is a curated list, not a framework. Quality varies across the entries. Some are polished, some are experiments. And it is Codex-only. It does not work with Claude Code, Cursor, or other AI coding tools, so the value evaporates the moment you switch assistants.
