OrchestKit

Reference Skills

The 81 user-invocable:false skills auto-injected into agent context — the knowledge library behind OrchestKit agents.

What Are Reference Skills?

Reference skills are the 81 skills with user-invocable: false in their frontmatter. You never invoke them directly — they are automatically injected into agent context through three paths:

  1. Agent frontmatter — each agent declares the skills it needs; when the agent spawns, those skills load automatically.
  2. Command-skill composition — a command skill (e.g. /ork:implement) pulls in reference skills via its skills: field.
  3. Keyword auto-suggest — the skill-auto-suggest hook injects matching skills based on keywords in your prompt.

Skills are grouped below by the agent: field they declare. Skills with no agent: are cross-cutting — shared across agents or the core system.

How Reference Skills Get to Agents

The link between a reference skill and its agent is bidirectional: the skill's agent: field names its owning agent, and the agent's skills: array lists the skills it loads. When an agent spawns, Claude Code injects each listed skill's content into the agent's context window.
