## What cyber-agentkit does, in the publisher's words

An agent-harness-agnostic toolkit. It provides the fundamental features agent tools need and makes each one work the same way across harnesses:

- Harness knowledge. Detect which harness is running, and query what it holds: managed-policy locations, plugin storage, installed and enabled plugins, skill naming and directories, and how to run it headless.
- Plugin dependencies. Check which plugins another plugin needs against what the harness has.
- Reference documents. Resolve the named Markdown documents an agent reads on demand.
- Worktrees. Lease git worktrees to concurrent agent sessions.

It depends on no other agent tool, so any of them can build on it.

Status: pre-release. Every fact this library encodes rests on.research/harness-detection.

## Skills

- reference: Use this skill when loading, creating, updating, deleting, finding, or inspecting a reference, a Markdown document agents read by name, or when wiring a skill to load one.
