**MakerAI ChatTools is the official capability-extension framework for MakerAI.**

Built natively in **Delphi**, ChatTools allows Artificial Intelligence models to *see, hear, read, speak, and act* by attaching real-world skills such as **PDF processing, OCR, Vision, Speech, Web Search, and Code Interpretation**, fully integrated into the MakerAI intelligent orchestration pipeline.

---

## 🧠 1. Philosophy: Separated Intelligence

MakerAI adopts a clear architectural principle: **separate intelligence from skills**.

- **Intelligence (LLMs)**  
  The *brain* — models such as GPT-5.x, Gemini 3.x, Claude 4.x, or Llama-based local models. They excel at reasoning and language understanding but are often *blind* or *deaf* to physical files and external systems.

- **Skills (ChatTools)**  
  The *senses and muscles* — deterministic tools that interact with the real world. Examples include **Ghostscript**, **DeepSeek-OCR**, speech engines, vision models, and web connectors.

**The problem we solve:**

- No spaghetti code
- No hard dependency on expensive multimodal models
- No vendor lock-in

If your AI model only understands text, MakerAI can *lend it eyes and ears* through ChatTools — transparently and predictably.

---

## 🧠 2. Core Orchestration Concepts

### The Universal Envelope (`TAiMediaFile`)

Raw files are never passed directly to models. Instead, MakerAI wraps them in a unified container:

- **Content**: binary stream of the file
- **Category**: automatic detection (PDF, Image, Audio)
- **Transcription**: extracted or generated text
- **Processed State**: prevents duplicate processing

This abstraction allows tools and models to cooperate safely and efficiently.

### The Decision Tripod

Every orchestration decision is based on three capability vectors:

- `NativeInputFiles` — what the provider API accepts
- `ChatMediaSupports` — what the model truly understands
- `EnabledFeatures` — which ChatTools are active

This makes orchestration deterministic, explainable, and extensible.

---

## 🛠 3. Four Usage Scenarios

### A. Standalone Tool Usage

Ideal for batch processing and automation pipelines where no conversational AI is required.

```delphi
Text := TAiOllamaPdfTool.ExtractTextFromFile('C:\\docs\\invoice.pdf');
```

---

### B. Automatic Orchestration (Bridge Mode)

For *blind* or lightweight local models. MakerAI intercepts the file, runs the local tool, and injects the extracted text into the conversation.

```delphi
AiOllamaChat1.PdfTool := AiOllamaPdfTool1;
AiOllamaChat1.ChatMediaSupports := [];
AiOllamaChat1.EnabledFeatures := [Tcm_Pdf];
AiOllamaChat1.Run(AskMsg);
```

---

### C. Function Calling (AI as Director)

The AI decides *when* to invoke a tool. Requires models with `use_tools` support.

```delphi
procedure TForm1.OnAiFunctionsAction(Sender: TObject; ToolCall: TAiToolsFunction; ...);
begin
  if ToolCall.AskMsg.MediaFiles.Count > 0 then
    ToolCall.Response := AiOllamaPdfTool1.ExtractText(
      ToolCall.AskMsg.MediaFiles[0].Content,
      'temp.pdf'
    );
  Handled := True;
end;
```

---

### D. Native Multimodal Processing

For cloud models that natively support file input (e.g., GPT-4o, Gemini).

```delphi
AiOllamaChat1.ChatMediaSupports := [Tcm_Pdf];
AiOllamaChat1.NativeInputFiles := [Tfc_Pdf];
```

---

## 📊 4. Strategy Comparison

| Feature | Standalone | Bridge | Function Calling | Native |
|-------|-----------|--------|------------------|--------|
| Intelligence | None | MakerAI | AI Model | AI Model |
| Speed | Very High | High | Medium | Very High |
| Token Cost | Zero | Low | Medium | High |
| Best Use Case | Automation | Local Models | AI Agents | Visual Analysis |

---

## 🚀 5. Creating a New ChatTool

To implement a new tool (e.g., Text-to-Speech), inherit from the appropriate base class and follow the reporting lifecycle.

```delphi
type
  TAiMySpeechTool = class(TAiSpeechToolBase)
  protected
    procedure ExecuteSpeechGeneration(const AText: string; ResMsg, AskMsg: TAiChatMessage); override;
  end;
```

### Lifecycle Rules

1. Run asynchronously if required (`TTask.Run`)
2. Report progress (`ReportState`)
3. Attach generated media (`ResMsg.AddMediaFile`)
4. Signal completion (`ReportDataEnd`)

---

## 🔍 6. Deep Dive: PDF + OCR Lessons Learned

Key rules discovered while implementing the Ghostscript + DeepSeek-OCR pipeline:

- Vision models require a newline separator before prompts
- Prompts must be lowercase
- Ghostscript ≥10.x requires `-dNOSAFER`
- Use `<|ocr|>` prefixes to force pure OCR output

---

## 📋 7. Requirements & Interfaces

### Technical Requirements

- MakerAI v3.2+ (Beta)
- Ghostscript installed
- Ollama with vision-capable models

### Available Interfaces

- `IAiPdfTool`
- `IAiSpeechTool`
- `IAiVisionTool`
- `IAiWebSearchTool`
- `IAiCodeInterpreter`
