When bundles beat installing each skill manually
Use a bundle when: You always pair the same skills for a recurring task ( /backend-dev , /release-prep , /incident-response ). You want a one-character-shorter mental model than typing several /skill invocations in a row. You want to ship a team-wide "task profile" by checking the bundle YAML into a shared dotfiles repo and symlinking it into ~/.hermes/skill-bundles/ . A bundle is just a YAML alias - it doesn't install skills for you. The skills themselves must already be present (in ~/.hermes/skills/ or an external skill directory). Otherwise the bundle invocation just skips the missing ones.
