Progressive Disclosure
Skills use a token-efficient loading pattern: The agent only loads the full skill content when it actually needs it.
From the official Hermes Agent documentation.
Level 0: skills_list() → [{name, description, category}, ...] (~3k tokens)
Level 1: skill_view(name) → Full content + metadata (varies)
Level 2: skill_view(name, path) → Specific reference file (varies)
