From ea7b293299f830734a186e5a92a802c167912722 Mon Sep 17 00:00:00 2001 From: leduclinh Date: Tue, 3 Feb 2026 18:11:52 +0900 Subject: [PATCH 01/21] feat: Implement AI enrichment for observations and enhance session management - Added ai-enrichment.ts to handle AI-generated insights for tool observations. - Integrated AI enrichment into MemoryHookService for enhanced observation data. - Introduced user prompt tracking with saveUserPrompt and getSessionPrompts methods. - Enhanced session summary generation to include structured summaries and user prompts. - Updated database schema to support new fields for observations and session summaries. - Improved markdown generation to include recent user prompts and session summaries. - Added utility functions for extracting facts and concepts from tool usage. - Updated vitest configuration to include setup files for testing. --- package-lock.json | 318 ++++++++++++ package.json | 1 + src/__tests__/setup.ts | 8 + src/cli/web-viewer.ts | 234

no-op tool calls in hook handlers. - Add tests for spawning enrich workers when AI enrichment is enabled. - Create a new test suite for MemoryHookService covering task queue, worker lifecycle, session summaries, user prompts, and transcript extraction. - Enhance existing tests for generating narratives and extracting facts from various tools. - Ensure proper handling of edge cases in narrative

Only fetch what you need.

Session context injection happens automatically on next session start | +| **Local embeddings, no API calls** | Vector search uses a local ONNX model (multilingual-e5-small). Semantic search works offline, costs nothing, and supports 100+ languages | +| **Background workers** | AI enrichment, embedding generation, and compression run asynchronously. Your coding flow is never blocked | +| **Multi-platform from day one** | One `--platform=all` flag configures Claude Code, Cursor, Windsurf, Cline, and OpenCode simultaneously. Same memory database, different editors | +| **Structured observation data** | Tool usage is captured with type classification (read/write/execute/search), file tracking, intent detection, and AI-generated narratives — not raw text dumps | +| **No process leaks** | Background workers self-terminate after 5 minutes, use PID-based lock files with stale-lock cleanup, and handle SIGTERM/SIGINT gracefully.
