Agent skills are sets of instructions that extend your AI agent with Doppels capabilities. Install a skill once and your agent knows how to freeze any working session into a replayable YAML Capability and Recipe — no re-prompting, no re-explaining, no re-doing. Skills live alongside your agent configuration and activate automatically whenever you ask for a freeze.
