Visual setup and architecture guide for Agents

01 // How It Works & Runtime Architecture

Integrates directly into AI code assistants and developer CLI harnesses. It exposes deterministic code analysis tools, inspects local repository trees, and provides isolated sandboxing so coding agents can inspect AST nodes, execute tests, and propose accurate patches without side effects.

02 // Real-World Workflows & Use Cases

01

Deterministic AST code analysis, symbol indexing, and cross-file reference discovery

02

Autonomous test generation, test execution feedback loops, and automated patch creation

03

Safe repository refactoring and automated codebase modernization without context leakage

03 // Prerequisites & Compatibility

✓
Runtime Environment
Node.js 18+ installed and available in system PATH
✓
Compatible Client
Claude Desktop, Cursor, Windsurf, Claude Code CLI, or OpenCode
✓
Directory Permissions
Explicit filesystem read/write access to designated directories
✓
License Compliance
Verified permissive MIT open-source license

04 // Client Configuration (claude_desktop_config.json) 

{
  "mcpServers": {
    "agents": {
      "command": "npx",
      "args": [
        "-y",
        "@modelcontextprotocol/server-agents"
      ]
    }
  }
}

Paste into your client configuration file (e.g. ~/Library/Application Support/Claude/claude_desktop_config.json on macOS or %APPDATA%/Claude/claude_desktop_config.json on Windows).

05 // Step-by-Step Installation

Verified Process
  1. 1

    Ensure you have Claude Code CLI or Claude Desktop installed with skills support enabled

  2. 2

    Clone or copy the skill directory from wshobson/agents into your local repository's '.claude/skills/' directory

  3. 3

    Install any required Python or Node runtime dependencies specified in the skill manifest

  4. 4

    Prompt your assistant (e.g. 'Use Agents to process current workspace assets')

06 // Execution Boundaries & Security Safeguards

● Context Protection

Keeps heavy parsing and raw file structures external to the LLM. Only sanitized excerpts and structured returns are injected into agent memory turns.

● Directory Allowlisting

Enforce explicit directory allowlists and permission scopes in client configuration to ensure autonomous tool calls never breach system boundaries.

● Process Isolation

Executes in an isolated local child process communicating strictly over JSON-RPC via stdio with explicit process timeouts.

07 // Frequently Asked Questions

FAQ Schema Included

What is Agents and how does it empower AI agents?

Agents is an open-source coding capability designed for AI clients and autonomous agents. Multi-harness agentic plugin marketplace for Claude Code, Codex, Cursor, OpenCode, GitHub Copilot, Google Antigravity, and Pi.

How do I install and configure Agents?

Follow the step-by-step installation: 1) Verify your runtime (Node.js 18+), 2) Add the configuration snippet into your AI client settings (e.g. claude_desktop_config.json), 3) Restart the client to initialize tool execution.

Which AI clients and developer harnesses support Agents?

Agents is compatible with all AI tools supporting tool-calling and the Model Context Protocol (MCP), including Claude Desktop, Cursor, Claude Code CLI, Windsurf, OpenCode, and custom agent runtimes.

What security boundaries and sandboxing safeguards does Agents enforce?

Agents executes locally with strict directory allowlists and permission scopes. Heavy parsing and raw file structures stay external to the LLM context window to prevent memory saturation and unauthorized access.

Is Agents free and open source?

Yes, Agents is published under the MIT open-source license. You can inspect the source code and contribute on GitHub at https://github.com/wshobson/agents.
