OpenAI developer documentation shows that Codex now supports "Agent Skills", which are used to package task-specific instructions, resources, and optional scripts into reusable capabilities, which can be used in Codex CLI and IDE extensions. Users can either explicitly invoke a skill through $.skill-name or describe the requirement in a prompt, allowing Codex to automatically select the appropriate skill to complete the process.
The skills mechanism emphasizes shareability and combinability: teams can precipitate common specifications, troubleshooting steps, code review points, etc. into a skill base, reducing the cost of repeated communication and improving execution consistency. The official description states that skills are based on the open Agent Skills standard and are easy to disseminate and reuse within teams or communities.
At the same time, the Codex changelog mentions that when explicitly selecting a skill, the corresponding SKILL.md content will be injected into the dialogue round, and it will be loaded on demand in the session, and an alarm will be prompted when the file is unreadable. For users, this means that while gaining stronger process capabilities, they also need to pay attention to the security of skill content, permission boundaries, and risks caused by script execution.
