From f3c08bf4c2d2fedca0a92410095448761c83477e Mon Sep 17 00:00:00 2001 From: Claude Date: Sun, 16 Nov 2025 16:41:05 +0000 Subject: [PATCH 1/4] feat: add Claude Agent SDK provider integration Add support for Claude Agent SDK as a new LLM provider, enabling the use of local Claude Code without API keys. Key changes: - Created ClaudeAgentSDKModel wrapper implementing Agno Model interface - Implemented aresponse() and aresponse_stream() methods using claude_agent_sdk.query() - Added ClaudeAgentSDKStrategy to provider configuration system - Registered new provider in ConfigurationManager - Added claude-agent-sdk to project dependencies - Updated documentation (CLAUDE.md, README.md) with new provider details Benefits: - No API key required - uses locally installed Claude Code - Seamless integration with existing Multi-Thinking architecture - Full support for all thinking agents and workflows - Native Agno framework compatibility Provider usage: ```bash LLM_PROVIDER="claude-agent-sdk" # No additional configuration needed ``` --- CLAUDE.md | 11 +- README.md | 6 +- pyproject.toml | 1 + .../config/modernized_config.py | 43 ++- .../models/__init__.py | 7 + .../models/claude_agent_sdk.py | 276 ++++++++++++++++++ uv.lock | 27 +- 7 files changed, 359 insertions(+), 12 deletions(-) create mode 100644 src/mcp_server_mas_sequential_thinking/models/__init__.py create mode 100644 src/mcp_server_mas_sequential_thinking/models/claude_agent_sdk.py diff --git a/CLAUDE.md b/CLAUDE.md index 7d99a7d..0f9184e 100644 --- a/CLAUDE.md +++ b/CLAUDE.md @@ -57,8 +57,8 @@ External LLM → sequentialthinking tool → ThoughtProcessor → WorkflowExecut ### Configuration & Data Flow **Environment Variables:** -- `LLM_PROVIDER`: Provider selection (deepseek, groq, openrouter, ollama, github, anthropic) -- `{PROVIDER}_API_KEY`: API keys (e.g., `DEEPSEEK_API_KEY`, `GITHUB_TOKEN`) +- `LLM_PROVIDER`: Provider selection (deepseek, groq, openrouter, ollama, github, anthropic, claude-agent-sdk) +- `{PROVIDER}_API_KEY`: API keys (e.g., `DEEPSEEK_API_KEY`, `GITHUB_TOKEN`) - **Not required for claude-agent-sdk** - `{PROVIDER}_ENHANCED_MODEL_ID`: Enhanced model for complex synthesis (Blue Hat) - `{PROVIDER}_STANDARD_MODEL_ID`: Standard model for individual hat processing - `EXA_API_KEY`: Research capabilities (if using research agents) @@ -122,6 +122,13 @@ External LLM → sequentialthinking tool → ThoughtProcessor → WorkflowExecut **Examples:** ```bash +# Claude Agent SDK (uses local Claude Code - no API key needed!) +LLM_PROVIDER="claude-agent-sdk" +# No API key required - uses locally installed Claude Code +# Model IDs are informational - Claude Code uses its internal models +CLAUDE_AGENT_SDK_ENHANCED_MODEL_ID="claude-sonnet-4-5" # Both synthesis and processing +CLAUDE_AGENT_SDK_STANDARD_MODEL_ID="claude-sonnet-4-5" + # GitHub Models GITHUB_ENHANCED_MODEL_ID="openai/gpt-5" # Blue Hat synthesis GITHUB_STANDARD_MODEL_ID="openai/gpt-5-min" # Individual hats diff --git a/README.md b/README.md index 4b81d9d..0875d8d 100644 --- a/README.md +++ b/README.md @@ -202,6 +202,7 @@ Research is **optional** - requires `EXA_API_KEY` environment variable.

Tool Management (allowed_tools)** - Map Agno tools to Claude Agent SDK allowed_tools - ReasoningTools → 'Think' tool - ExaTools → 'search_exa' tool - Support for Function objects and dict-based tools - Intelligent tool name mapping **2. Model Configuration** - Pass model ID explicitly via options.model - Ensures Claude Code uses correct model version **3. Permission Mode** - Add permission_mode parameter with 4 modes: * 'default': Standard permissions with prompts * 'acceptEdits': Auto-accept file edits * 'plan': Plan mode for reviewing actions * 'bypassPermissions': Bypass all checks (default for automation) - Configurable per-instance for different use cases **4. Working Directory (cwd)** - Support custom working directory - Defaults to current directory via Path.cwd() - Enables context-aware file operations **5. Tool Calls Extraction** - Extract and parse tool_use blocks from responses - Include tool calls in ModelResponse.tool_calls - Support both object and dict-based tool blocks - Track tool invocations (Think, search, etc.) **Benefits:** - Full control over Claude Code behavior - Better tool integration with Agno framework - Visibility into tool usage via tool_calls - Context-aware operations via cwd - Flexible permission management for different scenarios **What's NOT included (as requested):** -
