CodexSkillsCodex Skills vs AGENTS.md
How project-wide agent guidance differs from task-specific skills.
AGENTS.md gives project-level guidance. It tells the agent how to behave inside a repository: code style, testing expectations, business rules, and constraints.
A skill gives task-level guidance. It tells the agent how to complete one repeatable workflow.
You want both. AGENTS.md sets the house rules. Skills provide the operating procedures for specific jobs.
For example, AGENTS.md might say "build mobile-first, run typecheck, avoid fake reviews." A skill might say exactly how to write a product comparison page or debug a checkout webhook.
Every CodexSkills pack includes an AGENTS.md template plus task-specific skill folders. Start with the free starter pack, then browse all packs.
