Hermes Agent: Skills System Deep Dive

What It Is

Skills are on-demand knowledge documents (SKILL.md files) that the agent loads when needed. Progressive disclosure minimizes token usage — the agent only loads full content when actually executing a skill.

Architecture

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)

How ngn-agent Should Use This

DON'T BUILD a custom skill system — Hermes already has it. Instead:

  1. Author custom skills as SKILL.md files in ~/.hermes/skills/ or via the skill hub tap system
  2. Use skill bundles to group related infra workflows under one command
  3. Let the agent self-improveskill_manage tool creates/updates skills after complex tasks
  4. Publish as a tap if sharing with a team: hermes skills tap add myorg/ngn-skills

Key Capabilities for ngn-agent

Capability Description Use for ngn-agent
Skill Hub install hermes skills install openai/skills/k8s Install community infra skills
Agent-created skills Agent auto-saves workflows as skills Self-improving diagnostic skills
Skill bundles hermes bundles create infra --skill aws-diagnostics --skill jira Group related tools
External dirs skills.external_dirs: [~/.agents/skills] Share skills across tools
Conditional activation fallback_for_toolsets/frequires_toolsets Only show skills when needed
Write approval gating skills.write_approval: true Safety gate for agent-created skills

Limitations

  • Skills are per-profile (each Hermes profile has its own ~/.hermes/skills/)
  • External dirs are not read-only by default (agent can modify shared skills)
  • Skills Hub requires GitHub API (60 req/hr unauthenticated, 5000 with GITHUB_TOKEN)
