From 95556ba9eac3d98d7a330b4d9f39fd18d7ed1c24 Mon Sep 17 00:00:00 2001 From: Beehive Innovations Date: Tue, 17 Jun 2025 10:53:17 +0400 Subject: [PATCH] Add Consensus Tool for Multi-Model Perspective Gathering (#67) MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit * WIP Refactor resolving mode_names, should be done once at MCP call boundary Pass around model context instead Consensus tool allows one to get a consensus from multiple models, optionally assigning one a 'for' or 'against' stance to find nuanced responses. * Deduplication of model resolution, model_context should be available before reaching deeper parts of the code Improved abstraction when building conversations Throw programmer errors early * Guardrails Support for `model:option` format at MCP boundary so future tools can use additional options if needed instead of handling this only for consensus Model name now supports an optional ":option" for future use * Simplified async flow * Improved model for request to support natural language Simplified async flow * Improved model for request to support natural language Simplified async flow * Fix consensus tool async/sync patterns to match codebase standards CRITICAL FIXES: - Converted _get_consensus_responses from async to sync (matches other tools) - Converted store_conversation_turn from async to sync (add_turn is synchronous) - Removed unnecessary asyncio imports and sleep calls - Fixed ClosedResourceError in MCP protocol during long consensus operations PATTERN ALIGNMENT: - Consensus tool now follows same sync patterns as all other tools - Only execute() and prepare_prompt() are async (base class requirement) - All internal operations are synchronous like analyze, chat, debug, etc. TESTING: - MCP simulation test now passes: consensus_stance ✅ - Two-model consensus works correctly in ~35 seconds - Unknown stance handling defaults to neutral with warnings - All 9 unit tests pass (100% success rate) The consensus tool async patterns were anomalous in the codebase. This fix aligns it with the established synchronous patterns used by all other tools while maintaining full functionality. 🤖 Generated with [Claude Code](https://claude.ai/code) Co-Authored-By: Claude * Fixed call order and added new test * Cleanup dead comments Docs for the new tool Improved tests --------- Co-authored-by: Claude --- CLAUDE.md | 1 + README.md | 161 +++- config.py | 8 + server.py | 135 ++- simulator_tests/__init__.py | 9 + simulator_tests/base_test.py | 16 +- .../test_consensus_conversation.py | 222 +++++ simulator_tests/test_consensus_stance.py | 156 ++++ .../test_consensus_three_models.py | 153 ++++ systemprompts/__init__.py | 2 + systemprompts/consensus_prompt.py | 110 +++ test_enhanced_consensus.py | 138 +++ tests/test_consensus.py | 246 +++++ tests/test_large_prompt_handling.py | 68 +- tests/test_per_tool_model_defaults.py | 16 +- tests/test_server.py | 136 ++- tests/test_testgen.py | 38 +- tools/__init__.py | 2 + tools/analyze.py | 8 +- tools/base.py | 326 ++++--- tools/codereview.py | 8 +- tools/consensus.py | 846 ++++++++++++++++++ tools/debug.py | 8 +- tools/precommit.py | 8 +- tools/refactor.py | 14 +- tools/testgen.py | 14 +- tools/thinkdeep.py | 8 +- utils/conversation_memory.py | 71 +- utils/file_utils.py | 31 +- utils/model_context.py | 3 +- zen_server.py | 5 +- 31 files changed, 2643 insertions(+), 324 deletions(-) create mode 100644 simulator_tests/test_consensus_conversation.py create mode 100644 simulator_tests/test_consensus_stance.py create mode 100644 simulator_tests/test_consensus_three_models.py create mode 100644 systemprompts/consensus_prompt.py create mode 100644 test_enhanced_consensus.py create mode 100644 tests/test_consensus.py create mode 100644 tools/consensus.py diff --git a/CLAUDE.md b/CLAUDE.md index 197bc19..bf4f422 100644 --- a/CLAUDE.md +++ b/CLAUDE.md @@ -169,6 +169,7 @@ Available simulator tests include: - `testgen_validation` - TestGen tool validation with specific test function - `refactor_validation` - Refactor tool validation with codesmells - `conversation_chain_validation` - Conversation chain and threading validation +- `consensus_stance` - Consensus tool validation with stance steering (for/against/neutral) **Note**: All simulator tests should be run individually for optimal testing and better error isolation. diff --git a/README.md b/README.md index 209bcd1..47140b4 100644 --- a/README.md +++ b/README.md @@ -13,19 +13,19 @@ problem-solving, and collaborative development. **Features true AI orchestration with conversations that continue across tasks** - Give Claude a complex task and let it orchestrate between models automatically.
