Agents — AI Context Library

Reusable Claude Code components: skills, agents, commands, rules, plugins, MCP server configurations, and a universal component management system.

Quick Start

just init          # Install deps, init knowledge graph, pull embedding model
just agents --help # CLI tool for component management

CLI Commands

Skill Management

just agents skill add owner/repo@skill   # Install a skill
just agents skill find "kubernetes"       # Search registries
just agents skill list                    # List installed skills
just agents skill list --agent claude-code # Filter by agent
just agents skill outdated                # Check for updates
just agents skill update                  # Update outdated skills
just agents skill remove skill-name       # Remove a skill
just agents skill info skill-name         # Detailed metadata
just agents skill init my-skill           # Scaffold new skill

MCP Server Management

just agents mcp search "postgres"                        # Search Smithery registry
just agents mcp add smithery://ns/server --client cursor  # Add to client config
just agents mcp list --client claude-desktop              # List in client config
just agents mcp remove server-name --client cursor        # Remove from client
just agents mcp info ns/server-name                       # Server details
just agents mcp publish --name ns/server --url https://...# Publish to Smithery

Cross-Type Component Search

just agents component search "kubernetes"   # Search all types
just agents component list                  # List all installed
just agents component list --type agent     # Filter by type

Other Commands

just agents plugin check <name>    # Validate a plugin
just agents skill validate <name>  # Validate skill frontmatter
just kg-search "query"             # Semantic search (knowledge graph)

Component Model

All entity types flow through a universal ComponentProvider interface:

Provider	ID	Entity Types	Backend
LocalProvider	local	skill	Filesystem (wraps skill-* modules)
LocalAgentProvider	local-agent	agent	content/agents/**/*.md
LocalPluginProvider	local-plugin	plugin	content/plugins/**/.claude-plugin/
LocalRuleProvider	local-rule	rule	content/rules/**/*.md
LocalCommandProvider	local-command	command	content/commands/**/*.md
LocalOutputStyleProvider	local-output-style	output-style	content/output-styles/**/*.md
SmitheryProvider	smithery	mcp-server	registry.smithery.ai API

The ComponentManager aggregates search across all providers, deduplicates results, and handles pagination.

AI Client Config Support

MCP servers can be installed to 19 AI client config files:

Client	Method	Format
Claude Desktop	file	JSON
Claude Code	command	claude mcp add
Cursor	file	JSON
Windsurf	file	JSON
VS Code	command	code --add-mcp
Cline, Roo Code, Continue, Zed, Goose, OpenCode, ...	file	JSON/YAML/JSONC
