Anthropomorphic

CLI: anthro

Anthro operating instructions, packaged as a global MCP server + a multi-client installer for OpenCode, Claude Desktop, Cursor, and Cline / VS Code.

Extreme Token Optimization

Every decision is measured against context cost:

• Heavy checklists live on disk (~/.ant/skills/, assets/flowcharts.md), loaded via MCP tools on demand — never bloating the system prompt.
• UI stubs for OpenCode are dynamically written to ~/.config/opencode/skills/ during install — one-liner stubs that route slash-command UI entries to the corresponding MCP tools.
• The MCP server returns instructions + skill bodies + flowcharts only when a tool is called, not preloaded.

MCP Tools

| Tool | Purpose | |---|---| | run_ant_method | The core loop (think, act, prove). Returns the full Anthro behavioral rules + the ant-method skill + the master flowcharts. | | run_ant_loop | Multi-agent orchestration. Returns the rules + the ant-loop skill + the flowcharts. | | run_ant_judge | Adversarial verification (diffs, tests, fraud hunting). Returns the rules + the ant-judge skill + the flowcharts. | | run_ant_domain | Generating new domain adapters. Returns the rules + the ant-domain skill + the flowcharts. | | run_ant_philosophy | Fetch the core Anthro philosophy for one-shot development contexts. Returns the verbatim body of philosophy.md. |

Install

npm install -g anthropomorphic   # install globally from the npm registry
anthro                  # run the interactive installer (auto-detects active AI clients)

The installer auto-detects OpenCode, Claude Desktop, Cursor, and Cline/VS Code, then configures each with one prompt. For manual setup or a specific client, add the MCP config block directly (see Manual MCP Configuration below).

All available commands:

anthro          # interactive installer (auto-detect clients)
anthro --setup  # force-enable clients, bypass auto-detect
anthro init     # project-local install in CWD
anthro uninstall # cleanly remove (MCP configs, AGENTS.md blocks, skill stubs, ~/.ant/)
anthro serve    # start the MCP stdio server directly (for manual MCP host config)
anthro --help   # show all available commands

The installer:

1. Passively scans standard configuration paths for the 4 supported AI clients.
2. Asks one decision question: global agent root (recommended) or project-specific (anthro init).
3. Copies the skills/ directory and flowcharts.md into ~/.ant/.
4. Surgically writes the MCP server entry into each detected client's JSON config (preserving siblings and comments).
5. Appends a marker-fenced <!-- anthro:start -->...<!-- anthro:end --> block into the client's AGENTS.md (or CLAUDE.md for Claude Desktop's project config), containing the synthesized Anthro philosophy + tool directory + flowcharts hook.
6. For OpenCode, generates 5 skill stub files under ~/.config/opencode/skills/ that wire slash commands to MCP tools.

How it works

• The AGENTS.md block instructs the agent that flowcharts.md is the Master Reference Map and that it must be read before any complex workflow, via run_ant_method with task: "flowcharts.md".
• The MCP server's initialize response reinforces this.
• Each tool handler reads ~/.ant/skills/<skill>/SKILL.md, prepends the verbatim philosophy.md body and the flowcharts.md content, and returns the combined text as the tool response.

Manual MCP Configuration

If the installer does not detect your client or you prefer to configure manually:

OpenCode

Add to ~/.config/opencode/opencode.jsonc:

{
  "mcp": {
    "anthro": {
      "type": "local",
      "command": ["anthro", "serve"],
      "enabled": true
    }
  }
}

Claude Desktop

claude_desktop_config.json:

{
  "mcpServers": {
    "anthro": {
      "command": "anthro",
      "args": ["serve"]
    }
  }
}

Restart the client after adding the config. Verify the server responds correctly:

echo '{"jsonrpc":"2.0","id":1,"method":"initialize","params":{"protocolVersion":"2025-03-26","capabilities":{},"clientInfo":{"name":"test","version":"1.0"}}}' | anthro serve

Should return a JSON-RPC initialize response with the five run_ant_* tools listed in the server instructions.
