agentbrew-add-skill

Deploy a skill to all agents by registering a GitHub repository, local folder, or catalog entry as a source so agentbrew validates its SKILL.md frontmatter and syncs it to all agents on the next deployment.

Syncing local folder skills across agents requires adding the folder path as a source, which allows agentbrew to track the directory state in state.yaml and deploy updates during synchronized deployments.

Yes, installing a skill source requires a SKILL.md file with valid frontmatter in the skill directory, as agentbrew validates this structure before registering the source for synchronized updates.

Yes, you can use catalog installs to deploy secure, pre-vetted skills to all agents, ensuring that every agent receives the standardized skill upon the next synchronized deployment cycle.

Adding a skill source tracks state in ~/.config/agentbrew/state.yaml to store source metadata, which enables agentbrew to identify changes and execute synchronized updates across all configured agents.

You should not use this approach when creating skills from scratch, as this handles registering and syncing existing sources rather than authoring new skill directories.
