From 2bea057fb1834c67eb5bc5cc36f35160ac4176ed Mon Sep 17 00:00:00 2001 From: Felipe Cardoso Date: Sun, 4 Jan 2026 15:23:14 +0100 Subject: [PATCH] chore(context): refactor for consistency, optimize formatting, and simplify logic - Cleaned up unnecessary comments in `__all__` definitions for better readability. - Adjusted indentation and formatting across modules for improved clarity (e.g., long lines, logical grouping). - Simplified conditional expressions and inline comments for context scoring and ranking. - Replaced some hard-coded values with type-safe annotations (e.g., `ClassVar`). - Removed unused imports and ensured consistent usage across test files. - Updated `test_score_not_cached_on_context` to clarify caching behavior. - Improved truncation strategy logic and marker handling. --- backend/app/services/context/__init__.py | 82 +++++++---------- backend/app/services/context/adapters/base.py | 6 +- .../app/services/context/adapters/claude.py | 4 +- .../app/services/context/adapters/openai.py | 4 +- .../app/services/context/assembly/pipeline.py | 24 ++--- .../app/services/context/budget/allocator.py | 8 +- .../app/services/context/budget/calculator.py | 6 +- .../services/context/cache/context_cache.py | 20 ++-- .../context/compression/truncation.py | 22 +++-- backend/app/services/context/engine.py | 30 ++++-- backend/app/services/context/exceptions.py | 4 +- .../services/context/prioritization/ranker.py | 12 +-- .../app/services/context/scoring/composite.py | 22 ++--- .../app/services/context/scoring/priority.py | 12 +-- .../app/services/context/scoring/relevance.py | 21 ++++- .../app/services/context/types/__init__.py | 8 +- .../app/services/context/types/knowledge.py | 11 ++- backend/app/services/context/types/tool.py | 8 +- .../tests/services/context/test_adapters.py | 3 - .../tests/services/context/test_assembly.py | 12 ++- .../services/context/test_compression.py | 19 ++-- backend/tests/services/context/test_engine.py | 2 - .../tests/services/context/test_exceptions.py | 2 - backend/tests/services/context/test_ranker.py | 14 +-- .../tests/services/context/test_scoring.py | 92 ++++++++----------- backend/tests/services/context/test_types.py | 51 +++------- 26 files changed, 226 insertions(+), 273 deletions(-) diff --git a/backend/app/services/context/__init__.py b/backend/app/services/context/__init__.py index d0bd1cb..9be69e5 100644 --- a/backend/app/services/context/__init__.py +++ b/backend/app/services/context/__init__.py @@ -124,71 +124,55 @@ from .types import ( ) __all__ = [ - # Adapters - "ClaudeAdapter", - "DefaultAdapter", - "get_adapter", - "ModelAdapter", - "OpenAIAdapter", - # Assembly - "ContextPipeline", - "PipelineMetrics", - # Budget Management - "BudgetAllocator", - "TokenBudget", - "TokenCalculator", - # Cache - "ContextCache", - # Engine - "ContextEngine", - "create_context_engine", - # Compression - "ContextCompressor", - "TruncationResult", - "TruncationStrategy", - # Configuration - "ContextSettings", - "get_context_settings", - "get_default_settings", - "reset_context_settings", - # Exceptions + "AssembledContext", "AssemblyTimeoutError", + "BaseContext", + "BaseScorer", + "BudgetAllocator", "BudgetExceededError", "CacheError", + "ClaudeAdapter", + "CompositeScorer", "CompressionError", + "ContextCache", + "ContextCompressor", + "ContextEngine", "ContextError", "ContextNotFoundError", + "ContextPipeline", + "ContextPriority", + "ContextRanker", + "ContextSettings", + "ContextType", + "ConversationContext", + "DefaultAdapter", "FormattingError", "InvalidContextError", - "ScoringError", - "TokenCountError", - # Prioritization - "ContextRanker", - "RankingResult", - # Scoring - "BaseScorer", - "CompositeScorer", + "KnowledgeContext", + "MessageRole", + "ModelAdapter", + "OpenAIAdapter", + "PipelineMetrics", "PriorityScorer", + "RankingResult", "RecencyScorer", "RelevanceScorer", "ScoredContext", - # Types - Base - "AssembledContext", - "BaseContext", - "ContextPriority", - "ContextType", - # Types - Conversation - "ConversationContext", - "MessageRole", - # Types - Knowledge - "KnowledgeContext", - # Types - System + "ScoringError", "SystemContext", - # Types - Task "TaskComplexity", "TaskContext", "TaskStatus", - # Types - Tool + "TokenBudget", + "TokenCalculator", + "TokenCountError", "ToolContext", "ToolResultStatus", + "TruncationResult", + "TruncationStrategy", + "create_context_engine", + "get_adapter", + "get_context_settings", + "get_default_settings", + "reset_context_settings", ] diff --git a/backend/app/services/context/adapters/base.py b/backend/app/services/context/adapters/base.py index cd0d6a0..967ac11 100644 --- a/backend/app/services/context/adapters/base.py +++ b/backend/app/services/context/adapters/base.py @@ -5,7 +5,7 @@ Abstract base class for model-specific context formatting.
