Completely removed the database context recall system while preserving database tables for safety. This major cleanup removes 80+ files and 16,831 lines of code. What was removed: - API layer: 4 routers (conversation-contexts, context-snippets, project-states, decision-logs) with 35+ endpoints - Database models: 5 models (ConversationContext, ContextSnippet, DecisionLog, ProjectState, ContextTag) - Services: 4 service layers with business logic - Schemas: 4 Pydantic schema files - Claude Code hooks: 13 hook files (user-prompt-submit, task-complete, sync-contexts, periodic saves) - Scripts: 15+ scripts (import, migration, testing, tombstone checking) - Tests: 5 test files (context recall, compression, diagnostics) - Documentation: 30+ markdown files (guides, architecture, quick starts) - Utilities: context compression, conversation parsing Files modified: - api/main.py: Removed router registrations - api/models/__init__.py: Removed model imports - api/schemas/__init__.py: Removed schema imports - api/services/__init__.py: Removed service imports - .claude/claude.md: Completely rewritten without context references Database tables preserved: - conversation_contexts, context_snippets, context_tags, project_states, decision_logs (5 orphaned tables remain for safety) - Migration created but NOT applied: 20260118_172743_remove_context_system.py - Tables can be dropped later when confirmed not needed New files added: - CONTEXT_SYSTEM_REMOVAL_SUMMARY.md: Detailed removal report - CONTEXT_SYSTEM_REMOVAL_COMPLETE.md: Final status - CONTEXT_EXPORT_RESULTS.md: Export attempt results - scripts/export-tombstoned-contexts.py: Export tool for future use - migrations/versions/20260118_172743_remove_context_system.py Impact: - Reduced from 130 to 95 API endpoints - Reduced from 43 to 38 active database tables - Removed 16,831 lines of code - System fully operational without context recall Reason for removal: - System was not actively used (no tombstoned contexts found) - Reduces codebase complexity - Focuses on core MSP work tracking functionality - Database preserved for safety (can rollback if needed) Co-Authored-By: Claude Sonnet 4.5 <noreply@anthropic.com>

Removes the entire conversation context/recall system from ClaudeTools.
|
|
|
|
This migration drops all context-related tables:
|
|
- context_tags (normalized tags table)
|
|
- project_states (project state tracking)
|
|
- decision_logs (decision documentation)
|
|
- conversation_contexts (main context storage)
|
|
- context_snippets (knowledge fragments)
|
|
|
|
WARNING: This is a destructive operation. All context data will be lost.
|
|
Make sure to export any important data before running this migration.
