+# AI MemoryCore
+*Coding Project - Created August 30, 2025*
+
+## Description
+Universal AI Memory Architecture — an open-source template for creating persistent AI companions that remember users across conversations. Uses simple markdown files as a database for identity, relationship memory, session RAM, and optional features like time awareness, project management, skill plugins, diary system, and memory recall.
+
+## Project Details
+- **Type**: Coding Project (Open Source)
+- **Status**: Active
+- **Created**: August 30, 2025
+- **Last Accessed**: February 20, 2026, 11:49 AM
+- **Position**: #1
+- **Repository**: GitHub (Public)
+- **Stars**: 100+ | **Forks**: 30+
+- **Commits**: 21
+
+## Technical Stack
+- **Languages**: Markdown (.md)
+- **Architecture**: File-based memory system (no database)
+- **Platform**: Cross-platform (any AI system with memory support)
+- **Primary Target**: Claude Code (Anthropic CLI) for skill auto-triggering
+- **Tools**: Git, Claude Code

+
+## Development Goals
+1. Provide simple, effective AI memory for everyone
+2. Modular feature extensions that users can install independently
+3. Production-proven patterns adapted from Alice's 20-enchantment system
+4. Cross-platform compatibility (Claude Code primary, others supported)
+
+## Progress Log
+
+### February 20, 2026 — Save Diary System & Echo Memory Recall (5 commits)
+- Added Save Diary System feature: install protocol + SKILL.md + README (references existing daily-diary-protocol.md)
+- Added Echo Memory Recall feature: 3-level search system (search+narrate, uncertainty guard, ask-user fallback)
+- Iterated Save Diary through 3 restructures: full feature → skill-only → install-feature with SKILL.md
+- Added Claude Code CLI platform notes to feature sections
+- Added emoji icons for visual consistency across all feature READMEs
+- Updated root README (v2.6) and master-memory.md with both features
+- Milestone: 100 stars, 30 forks celebration — community gift of 2 new features
+
+### February 18, 2026 — Skill Plugin System
+- Added Skill Plugin System feature for Claude Code auto-triggered skills
+- Added Memory Consolidation System with format templates
+
+### Earlier — Foundation
+- Time-based Aware System, LRU Project Management System
+- Core memory architecture (identity, relationship, session)
+- Setup wizard and save protocol
+
+## Current Tasks
+- [x] Add Save Diary System feature
+- [x] Add Echo Memory Recall feature
+- [x] Update root README v2.6
+- [x] Add platform notes for Claude Code requirement
+- [ ] Push all commits to remote
+
+## Known Issues
+- None
+
+## Session History
+- **Feb 20, 2026** — 5 commits (254a9e0): Save Diary + Echo Memory Recall features
+- **Feb 18, 2026** — 2 commits (cc6b095): Skill Plugin + Memory Consolidation
+- **Earlier** — Foundation commits
+
+## Memory Patterns
+- Feature pattern: README.md + install protocol + format/template file
+- All features self-delete after installation
+- Users customize feature names during install (Step 1 asks for name)
+- SKILL.md files require Skill Plugin System (Claude Code CLI)
+- Existing protocols (daily-diary-protocol.md) should be referenced, not duplicated
