What is agent_skills?

agent_skills is a small collection of reusable skills for AI agent environments. A skill is a self-contained folder you copy into the directory your agent reads from, giving it a new capability without changing any code in the agent itself. The only skill currently included is save-and-finish, described as an end-of-session protocol for research projects. When triggered, it writes a diary note for the current agent session and updates a project progress tracker, giving research workflows a consistent way to close out and record what happened during that session. Installation is a single copy command into whichever skills directory your agent environment uses. The README notes that this path varies by setup: some Codex configurations use a different skills folder than others, so you need to know which directory your own agent installation reads from before copying the folder in. The README does not provide further detail about supported agent platforms, the exact format of the diary notes, or the structure of the progress tracker. It is a small, single-purpose utility rather than a full framework.
