+**my-brain-importer** is a personal AI assistant and RAG (Retrieval-Augmented Generation) system written in Go. It ingests Markdown notes into a Qdrant vector database, answers questions using a local LLM (LocalAI), and is primarily controlled via Discord. A background daemon sends proactive email summaries and task reminders.

 ## Architecture
 
-Two CLI tools share a common internal library:
+```
+Discord (primäres Interface)
+    ↓ Slash-Commands + @Mention
+cmd/discord/main.go
+    ├── internal/agents/research/   → brain.AskQuery()
+    ├── internal/agents/memory/     → brain.RunIngest(), brain.IngestChatMessage()
+    ├── internal/agents/task/       → tasks.json (atomisches JSON)
+    └── internal/agents/tool/email/ → IMAP + LLM-Zusammenfassung
+              ↓
+    [Daemon-Goroutine] startDaemon()
+        ├── Email-Check (alle N min) → #localagent Discord-Channel
+        └── Task-Reminder (täglich)  → #localagent Discord-Channel
 
-**`cmd/ingest/`** → `internal/brain/ingest.go` + `internal/brain/ingest_json.go`
+cmd/ingest/ + cmd/ask/  (CLI-Tools, direkt nutzbar)
-- Markdown mode: recursively finds `.md` files, splits by `# `/`## ` headings, chunks long sections (max 800 chars) by paragraphs, embeds in batches of 10, upserts to Qdrant
+    ↓
-- JSON mode (when arg ends in `.json`): imports image description records with `file_path`, `file_name`, `description` fields
+internal/brain/         (Core RAG-Logik, unverändert)
+    ↓
+Qdrant (gRPC) + LocalAI (HTTP, OpenAI-kompatibel)
+```
 
-**`cmd/ask/`** → `internal/brain/ask.go`
+### Packages
-- Embeds the question, searches Qdrant (top-k, score threshold 0.5), deduplicates by text content, streams LLM response constrained to retrieved context
 
-**`internal/config/config.go`** initializes all clients: gRPC connection to Qdrant and OpenAI-compatible HTTP clients for embeddings and chat (both point to LocalAI).
+| Package | Zweck |
+|---------|-------|
+| `cmd/discord/` | Discord Bot + Daemon (primärer Einstiegspunkt) |
+| `cmd/ask/` | CLI-Tool: Fragen stellen |
+| `cmd/ingest/` | CLI-Tool: Markdown/JSON importieren |
+| `cmd/mailtest/` | Testprogramm: IMAP + LLM-Test |
+| `internal/brain/` | Core RAG: Embeddings, Qdrant-Suche, LLM-Streaming |
+| `internal/config/` | Konfiguration + Client-Initialisierung (globale `Cfg`) |
+| `internal/agents/` | Agent-Interface (`Request`/`Response`) |
+| `internal/agents/research/` | Research-Agent: Wissensdatenbank-Abfragen |
+| `internal/agents/memory/` | Memory-Agent: Ingest + Chat-Speicherung |
+| `internal/agents/task/` | Task-Agent: Aufgabenverwaltung (tasks.json) |
+| `internal/agents/tool/` | Tool-Dispatcher |
+| `internal/agents/tool/email/` | IMAP-Client + LLM-Email-Analyse |
+
+### Discord Commands
+
+| Slash-Command | @Mention | Funktion |
+|---------------|----------|---------|
+| `/ask`, `/research` | `@bot <frage>` | Wissensdatenbank abfragen |
+| `/asknobrain` | – | Direkt an LLM (kein RAG) |
+| `/memory store` | `@bot remember <text>` | Text speichern |
+| `/memory ingest` | `@bot ingest` | Markdown neu einlesen |
+| `/task add/list/done/delete` | `@bot task <aktion>` | Aufgaben verwalten |
+| `/email summary/unread/remind` | `@bot email <aktion>` | Email-Analyse |
+| `/remember` | – | Alias für `/memory store` |
+| `/ingest` | – | Alias für `/memory ingest` |
 
 ## Key Patterns
 
 - **Deterministic IDs**: SHA256 of `source:text` — upserting the same content is always idempotent
 - **Excluded directories**: `05_Agents` and `.git` are skipped during markdown ingest
-- **config.yml** must be present in the working directory; defines Qdrant host/port/api_key, embedding model + dimensions, chat model, `brain_root` path, and `top_k`
+- **config.yml** must be present in the working directory at runtime
-- External services: Qdrant (gRPC port 6334) and LocalAI (HTTP, OpenAI-compatible API)
+- **Agent Interface**: alle Agenten implementieren `Handle(Request) Response`
+- **Defer-first Pattern**: Discord-Handlers senden sofort Defer, dann berechnen — nie >3s warten
+- **LLM-Fallback**: Email-Zusammenfassung zeigt Rohliste wenn LLM nicht erreichbar
+- **Daemon**: läuft als Goroutine im Discord-Bot-Prozess (`startDaemon()`)
+- **config.Cfg**: globale Variable — bei Tests muss `config.LoadConfig()` aufgerufen oder Cfg direkt gesetzt werden
+
+## Model Limitations
+
+Das konfigurierte Modell (`Qwen3.5-4B-Claude-4.6-Opus-Reasoning-Distilled-GGUF`) hat folgende Grenzen:
+
+- **Kontextfenster**: Begrenzt — bei sehr langen Email-Listen oder vielen Chunks kann die Antwort abgeschnitten werden (`MaxTokens: 600`)
+- **Latenz**: Lokales Modell auf NAS — Antwortzeiten variieren (5–60s je nach Last)
+- **Encoding**: Betreffzeilen in `windows-1252` (Strato) werden nicht dekodiert — das LLM interpretiert sie trotzdem meist korrekt
+- **Halluzinationen**: Das Modell kann bei unklarem Kontext eigenes Wissen einmischen — ist im System-Prompt mit "Aus meinem Wissen:" markiert
+- **Streaming-Timeout**: Kein expliziter Timeout auf LLM-Calls — bei Hänger wird Discord-Interaktion erst nach 15min ungültig
+
+## External Services
+
+- **Qdrant** (`192.168.1.4:6334`) — Vektordatenbank, gRPC
+- **LocalAI** (`192.168.1.118:8080`) — lokales LLM, OpenAI-kompatibles API
+- **Strato IMAP** (`imap.strato.de:143`, STARTTLS) — Email-Abruf
+- **Discord** — primäres Interface (Bot-Token in `config.yml`)
