Felipe Cardoso	dfa75e682e	feat(context): implement token budget management (Phase 2) ... Add TokenCalculator with LLM Gateway integration for accurate token counting with in-memory caching and fallback character-based estimation. Implement TokenBudget for tracking allocations per context type with budget enforcement, and BudgetAllocator for creating budgets based on model context window sizes. - TokenCalculator: MCP integration, caching, model-specific ratios - TokenBudget: allocation tracking, can_fit/allocate/deallocate/reset - BudgetAllocator: model context sizes, budget creation and adjustment - 35 comprehensive tests covering all budget functionality Part of #61 - Context Management Engine 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude Opus 4.5 <noreply@anthropic.com>	2026-01-04 02:13:23 +01:00
Felipe Cardoso	22ecb5e989	feat(context): Phase 1 - Foundation types, config and exceptions (#79) ... Implements the foundation for Context Management Engine: Types (backend/app/services/context/types/): - BaseContext: Abstract base with ID, content, priority, scoring - SystemContext: System prompts, personas, instructions - KnowledgeContext: RAG results from Knowledge Base MCP - ConversationContext: Chat history with role support - TaskContext: Task/issue context with acceptance criteria - ToolContext: Tool definitions and execution results - AssembledContext: Final assembled context result Configuration (config.py): - Token budget allocation (system 5%, task 10%, knowledge 40%, etc.) - Scoring weights (relevance 50%, recency 30%, priority 20%) - Cache settings (TTL, prefix) - Performance settings (max assembly time, parallel scoring) - Environment variable overrides with CTX_ prefix Exceptions (exceptions.py): - ContextError: Base exception - BudgetExceededError: Token budget violations - TokenCountError: Token counting failures - CompressionError: Compression failures - AssemblyTimeoutError: Assembly timeout - ScoringError, FormattingError, CacheError - ContextNotFoundError, InvalidContextError All 86 tests pass. 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude Opus 4.5 <noreply@anthropic.com>	2026-01-04 02:07:39 +01:00
