Codex vs Droid — FAQ
Should I pick Codex or Droid?
It depends on where you work. Codex is openai's coding agent cli, while Droid is factory's ai software engineering agent. Many developers use both and share skills across them via BuySkills — so the choice is less binary than it used to be.
Can I use the same plugins in Codex and Droid?
Yes. BuySkills is designed for cross-agent portability. Install a skill once with the BuySkills CLI and it becomes available in both Codex and Droid — and every other supported agent — without a second purchase or install.
How is installing BuySkills skills different between Codex and Droid?
It isn't, from your side. You run `npx buyskills install <skill>`, and the CLI writes the skill to the directory each agent reads from. Codex and Droid pick up the skill without any extra config.
Are BuySkills skills compatible with Codex's sandbox?
Yes. BuySkills skills are packaged as portable prompt + tool definitions that run inside Codex's sandbox the same way a local skill would. No special permissions are required beyond the ones the skill itself declares.
Do Droid's safety rails apply to BuySkills skills?
Yes. When Droid invokes a BuySkills skill, it runs through the same review, audit, and permission layers that Droid applies to any other tool call. Nothing bypasses Droid's safety guardrails.
Still deciding?
Install BuySkills CLI once and the skills you discover today work in whichever agent you pick tomorrow.
