Codex vs Goose — FAQ
Should I pick Codex or Goose?
It depends on where you work. Codex is openai's coding agent cli, while Goose is block's open-source agent framework. 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 Goose?
Yes. BuySkills is designed for cross-agent portability. Install a skill once with the BuySkills CLI and it becomes available in both Codex and Goose — and every other supported agent — without a second purchase or install.
How is installing BuySkills skills different between Codex and Goose?
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 Goose 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 BuySkills skills replace Goose extensions?
No — they complement them. Goose extensions wire raw tools into the agent runtime. BuySkills skills are higher-level, reusable capability bundles that Goose can call just like any other tool.
Still deciding?
Install BuySkills CLI once and the skills you discover today work in whichever agent you pick tomorrow.
