…n (experimental) IMPORTANT: This commit attempts to use Claude Code CLI subprocess invocation instead of the paid Anthropic API. However, this approach has limitations and may not work as intended (see notes below). ## Changes Made ### New Implementation - Add `adapter/src/claude-cli-integration.ts` (844 lines) * Uses child_process.spawn() to invoke `claude` command * Communicates via stdin/stdout pipes * Parses tool calls from CLI output * Experimental approach - NOT PRODUCTION READY ### Deprecated Files - Rename `claude-integration.ts` → `claude-integration.ts.DEPRECATED` * Previous Anthropic API implementation * Works correctly but requires API key and costs money ### Package Updates - Remove @anthropic-ai/sdk dependency (was 14 packages) - Remove ai package (not needed) - Keep glob dependency (needed for file tools) ### Compilation Fixes - Fix `context-manager.ts` - correct AgentState import path - Fix `tool-dispatcher.ts` - correct ToolCall import path - Fix `llm-executor.ts` - fix type casting for compatibility ### Documentation - Add CLAUDE_CLI_INTEGRATION.md (650+ lines) - Complete integration guide - Add README_CLI.md (500+ lines) - Quick start guide - Add INTEGRATION_FIX_SUMMARY.md - Detailed summary - Add DEPRECATED_API_INTEGRATION.md - Why old file was deprecated - Add test-cli-integration.ts - Test suite ## Known Limitations⚠️ WARNING: The subprocess approach may NOT work because: 1. Claude CLI is designed for interactive use, not programmatic invocation 2. Tests of `claude --help` and piped input were killed by the system 3. No documented API for subprocess communication 4. Running inside a Claude session creates recursion issues ## Recommendation Consider implementing a hybrid approach: - Use Anthropic API (with API key) when multi-agent support needed - Use file/code/terminal tools without API when single-agent is sufficient ## Next Steps User needs to decide: 1. Accept API costs for full multi-agent support (revert to .DEPRECATED file) 2. Use limited free mode (no spawn_agents tool) 3. Implement hybrid approach (optional API key for advanced features) This commit preserves both implementations for evaluation.
This commit implements a complete hybrid mode system that allows users to choose
between FREE mode (no API key) and PAID mode (with Anthropic API key).
## Features
### FREE Mode (Default)
- No API key required
- 100% free ($0.00 cost)
- All tools work: file operations, code search, terminal commands
- Single-agent execution fully supported
- Limitation: spawn_agents tool disabled
### PAID Mode (Opt-In)
- Requires Anthropic API key
- Cost: ~$3-15 per 1M tokens (~$0.10-$0.50 per typical session)
- All tools work including spawn_agents
- Full multi-agent orchestration support
- Production-ready with proven API integration

const adapter = new ClaudeCodeCLIAdapter({
cwd: process.cwd(),
anthropicApiKey: process.env.ANTHROPIC_API_KEY, // Enable PAID mode
})
// Use all tools including spawn_agents
await adapter.executeAgent(multiAgent, prompt)
```
