-## Overview
-
-MCP server for AI memory. 1 TID = 1 memory element. ATProto lexicon record format.
-
-## Design
-
-- AI decides, tool records
-- File I/O only, no database
-- 1 TID = 1 memory element (not a monolithic blob)
-- `memory` setting controls max record count (default: 100)
-- `compress` consolidates records when limit is exceeded
-- `instructions` in MCP initialize delivers core + all memories to client
-
-## MCP Tools
-
-| Tool | Args | Description |
-|------|------|-------------|
-| read_core | none | Returns core record (identity, personality) |
-| read_memory | none | Returns all memory records as array |
-| save_memory | content: string | Adds a single memory element |
-| compress | items: string[] | Replaces all records with compressed set |
-
-## Config
-
-```json
-{
-  "bot": {
-    "did": "did:plc:xxx",
-    "handle": "ai.syui.ai",
-    "path": "~/ai/log/public/content",
-    "memory": 100
-  }
-}
-```
-
-- Config file: `~/.config/ai.syui.gpt/config.json` (Linux) / `~/Library/Application Support/ai.syui.gpt/config.json` (macOS)
-- Same format as site config.json (`bot` field)
-- `memory`: max number of records (default: 100)
-
-## Data
-
-```
-$path/{did}/{collection}/{rkey}.json
-
-e.g.
-~/ai/log/public/content/
-└── did:plc:xxx/
-    ├── ai.syui.gpt.core/
-    │   └── self.json
-    └── ai.syui.gpt.memory/
-        ├── {tid1}.json   ← "syuiはRustを好む"
-        ├── {tid2}.json   ← "ATProto設計に詳しい"
-        └── {tid3}.json   ← "原神プレイヤー"
-```
-
-## Record Format
-
-core (rkey: self):
-```json
-{
-  "uri": "at://{did}/ai.syui.gpt.core/self",
-  "value": {
-    "$type": "ai.syui.gpt.core",
-    "did": "did:plc:xxx",
-    "handle": "ai.syui.ai",
-    "content": {
-      "$type": "ai.syui.gpt.core#markdown",
-      "text": "personality and instructions"
-    },
-    "createdAt": "2025-01-01T00:00:00Z"
-  }
-}
-```
-
-memory (rkey: tid, 1 element per record):
-```json
-{
-  "uri": "at://{did}/ai.syui.gpt.memory/{tid}",
-  "value": {
-    "$type": "ai.syui.gpt.memory",
-    "did": "did:plc:xxx",
-    "content": {
-      "$type": "ai.syui.gpt.memory#markdown",
-      "text": "syuiはRustを好む"
-    },
-    "createdAt": "2026-03-01T12:00:00Z"
-  }
-}
-```
-
-## Architecture
-
-```
-src/
-├── mcp/server.rs    ← JSON-RPC over stdio, instructions
-├── core/config.rs   ← config loading, path resolution
-├── core/reader.rs   ← read core.json, memory/*.json
-├── core/writer.rs   ← save_memory, compress_memory
-└── main.rs          ← CLI + MCP server
-```
-
-## Memory Flow
-
-1. `save_memory("fact")` → creates 1 TID file
-2. Records accumulate: 1 TID = 1 fact
-3. When records exceed `memory` limit → AI calls `compress`
-4. `compress(["kept1", "kept2", ...])` → deletes all, writes new set
-5. MCP `initialize` → delivers core + all memories as `instructions`
-
-## Compression Rules
-
-When compress is called, AI should:
-- Keep facts and decisions
-- Discard outdated or redundant entries
-- Merge related items
-- Resolve contradictions (keep newer)
-- Don't duplicate core.json content
-
-## Usage
-
-```bash
-aigpt                    # show config and status
-aigpt server             # start MCP server
-aigpt read-core          # read core record
-aigpt read-memory        # read all memory records
-aigpt save-memory "..."  # add a single memory element
-```
-
-## Tech
-
-- Rust, MCP (JSON-RPC over stdio), ATProto record format, file I/O only
-
-## History
-
-Previous versions (v0.1-v0.3) had multi-layer architecture with SQLite, Big Five personality analysis, relationship inference, gamification, and companion systems. Rewritten to current simple design.
