cyber-agentkit

Install

In Claude Code, add the marketplace and install the plugin:

/plugin marketplace add cyber-uni/marketplace
/plugin install cyber-agentkit@cyber-uni

For Cursor, Codex, and Copilot CLI, see Install.

To use it as a library instead:

npm install cyber-agentkit

import { detectHarness, skillsDirectories } from 'cyber-agentkit'

const { harness } = detectHarness() // 'claude-code', 'codex', …, or 'unknown'
if (harness !== 'unknown') skillsDirectories(harness)

The package depends on no other agent tool, so any of them can build on it. It also ships as the cyber-agentkit command; see the package overview.

What it answers

Which harness is running

detectHarness() identifies 13 harnesses from the variables they set, and reports unknown rather than guess.

Where policy lives

managedPolicyLocations() lists managed-policy files, MDM domains, registry keys, and server-side sources.

Which plugins are present

pluginStorage(), enabledPlugins(), and installedPlugins() say where plugins live, which are enabled, and which folder each one loads from.

How skills are named and found

skillInvocation() returns what a user types to run a plugin skill, and skillsDirectories() where a harness reads skills from.

Which reference applies

loadReference() resolves a named document across the managed, project, user, and plugin tiers, merging each override as its frontmatter asks.

Every answer rests on a vendor source recorded in .research/harness-detection. The package readme documents each function.
