@openagents-control/compatibility-layer

Compatibility layer for converting OpenAgents Control agents to/from other AI coding tools

Overview

This package provides bidirectional conversion between OpenAgents Control (OAC) agent format and various AI coding tools:

• Cursor IDE - VSCode-based AI editor with .cursorrules
• Claude Code - Anthropic's official CLI with config.json and agents/*.md
• Windsurf - AI-powered development environment with JSON config

Features

• ✅ Bidirectional conversion - Convert OAC ↔ Tool formats
• ✅ Feature parity tracking - Know what's supported in each tool
• ✅ Graceful degradation - Handle unsupported features with warnings
• ✅ CLI tool - Easy conversion from command line
• ✅ Batch migration - Migrate entire projects at once
• ✅ Type-safe - Full TypeScript with Zod validation
• ✅ Extensible - Plugin architecture for new tools

Installation

# npm
npm install @openagents-control/compatibility-layer

# pnpm
pnpm add @openagents-control/compatibility-layer

Quick Start

CLI Usage

# Convert a single file
oac-compat convert agent.md -f cursor -o .cursorrules

# Convert with auto-detection of source format
oac-compat convert .cursorrules -f oac -o agent.md

# Validate compatibility before conversion
oac-compat validate agent.md -t claude --strict

# Migrate entire project
oac-compat migrate ./agents -f claude --out-dir ./output

# Preview migration without writing files
oac-compat migrate ./agents -f windsurf --dry-run

# Show platform capabilities
oac-compat info cursor

# Compare two platforms
oac-compat info cursor --compare claude

Programmatic Usage

import {
  loadAgent,
  getAdapter,
  translate,
  analyzeCompatibility,
} from "@openagents-control/compatibility-layer";

// Load an OAC agent
const agent = await loadAgent("./agent.md");

// Check compatibility with target platform
const compatibility = analyzeCompatibility(agent, "cursor");
console.log("Compatible:", compatibility.compatible);
console.log("Warnings:", compatibility.warnings);
console.log("Blockers:", compatibility.blockers);

// Convert to another format
const adapter = getAdapter("claude");
const result = await adapter.fromOAC(agent);

if (result.success) {
  for (const config of result.configs) {
    console.log(`File: ${config.fileName}`);
    console.log(config.content);
  }
}

// Or use the translate function for quick conversion
const translated = translate(agent, "cursor");

API Reference

Agent Loading

import {
  loadAgent,
  loadAgents,
  AgentLoader,
} from "@openagents-control/compatibility-layer";

// Load single agent
const agent = await loadAgent("./agent.md");

// Load all agents from directory
const agents = await loadAgents("./agents/");

// Using the loader class
const loader = new AgentLoader();
const agent = await loader.loadFromFile("./agent.md");

Adapter Registry

import {
  registry,
  getAdapter,
  listAdapters,
} from "@openagents-control/compatibility-layer";

// Get adapter by name
const adapter = getAdapter("cursor");

// List all adapters
const names = listAdapters(); // ['cursor', 'claude', 'windsurf']

// Get all capabilities
const capabilities = getAllCapabilities();

Translation Engine

import {
  translate,
  previewTranslation,
  TranslationEngine,
} from "@openagents-control/compatibility-layer";

// Quick translate
const result = translate(agent, "cursor");

// Preview without converting
const preview = previewTranslation(agent, "claude");
console.log("Features lost:", preview.featuresLost);
console.log("Features gained:", preview.featuresGained);

// Using the engine for more control
const engine = new TranslationEngine();
const result = engine.translate(agent, "windsurf", {
  preserveComments: true,
  strictMode: false,
});

Mappers

import {
  mapToolFromOAC,
  mapModelFromOAC,
  mapPermissionsFromOAC,
  mapContextPathFromOAC,
} from "@openagents-control/compatibility-layer";

// Map tool names
mapToolFromOAC("bash", "cursor"); // { name: 'terminal', exact: true }

// Map model identifiers
mapModelFromOAC("claude-sonnet-4", "cursor"); // { id: 'claude-3-sonnet', exact: true }

// Map permissions
mapPermissionsFromOAC({ bash: { "*": "allow" } }, "claude");
// { permissions: { bash: true }, warnings: [...] }

Creating Custom Adapters

import {
  BaseAdapter,
  OpenAgent,
  ConversionResult,
  ToolCapabilities,
} from "@openagents-control/compatibility-layer";

class MyToolAdapter extends BaseAdapter {
  readonly name = "my-tool";
  readonly displayName = "My Tool";
  readonly version = "1.0.0";

  getCapabilities(): ToolCapabilities {
    return {
      supportsMultiAgent: false,
      supportsSkills: false,
      supportsHooks: false,
      supportsGranularPermissions: false,
      configFormat: "json",
    };
  }

  async toOAC(source: string): Promise<OpenAgent> {
    // Parse source and return OpenAgent
  }

  async fromOAC(agent: OpenAgent): Promise<ConversionResult> {
    // Convert OpenAgent to your format
    return {
      success: true,
      configs: [{ fileName: "config.json", content: "...", encoding: "utf-8" }],
      warnings: [],
    };
  }
}

// Register the adapter
import { registry } from "@openagents-control/compatibility-layer";
registry.register(new MyToolAdapter());
