Codex vs Kilo — FAQ
Should I pick Codex or Kilo?
It depends on where you work. Codex is openai's coding agent cli, while Kilo is open-source autonomous coding agent, vs code. 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 Kilo?
Yes. BuySkills is designed for cross-agent portability. Install a skill once with the BuySkills CLI and it becomes available in both Codex and Kilo — and every other supported agent — without a second purchase or install.
How is installing BuySkills skills different between Codex and Kilo?
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 Kilo 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.
Does Kilo pick up new skills without restart?
Yes. BuySkills writes to Kilo's skill directory on install, and Kilo re-scans before each agent run. New skills are available immediately without reloading VS Code.
Still deciding?
Install BuySkills CLI once and the skills you discover today work in whichever agent you pick tomorrow.
