# VTK Sequential Thinking

RAG-based VTK Python code generation with prompt clarification, task decomposition, and sequential code generation.

## Overview

This project turns a user prompt into runnable VTK Python code via three stages:

- Prompt clarification (`ClarificationSession`)
- Task decomposition (`DecompositionSession`)
- Code generation (`GenerationSession`)

---

## Quick Start

### Prerequisites

- Python 3.10+
- [uv](https://docs.astral.sh/uv/) - Fast Python package manager

```bash
# Install uv if not already installed
curl -LsSf https://astral.sh/uv/install.sh | sh
```

### 1. Run Setup

```bash
./setup.sh
```

This creates a `.venv` virtual environment using uv and installs dependencies interactively.

**Or install manually:**

```bash
# Create virtual environment
uv venv .venv
source .venv/bin/activate

# Install package with dev dependencies
uv pip install -e ".[dev]"

# Optional extras
uv pip install -e ".[llm]"   # LLM providers
uv pip install -e ".[mcp]"   # VTK API tooling
uv pip install -e ".[rag]"   # RAG (requires Qdrant)
uv pip install -e ".[vtk]"   # VTK runtime

# All extras
uv pip install -e ".[dev,llm,mcp,rag,vtk]"
```

### 2. Configure Environment

```bash
cp .env.example .env
# Edit .env with your LLM API key
```

### 3. Start Qdrant

```bash
docker run -d -p 6333:6333 qdrant/qdrant
```

### 4. Index Your Data

You'll need to index your VTK documentation. The data files are:
- `data/vtk-python-docs.jsonl` (61 MB) - API documentation
- `data/raw/vtk-python-examples.jsonl` (5.4 MB) - Code examples
- `data/raw/vtk-python-tests.jsonl` (4.8 MB) - Test cases

**Note**: Indexing tools are in the parent [vtk-rag](https://github.com/your-username/vtk-rag) repository. You need to build the Qdrant index before querying.

### 5. Use the CLI

```bash
source .venv/bin/activate
vtk-st --help

# Evaluate prompt clarity
vtk-st evaluate "Read a VTK file and visualize it"

# Clarify a prompt (interactive by default)
vtk-st query "Read a VTK file and visualize it"

# Decompose into tasks
vtk-st decompose "Read volume.vti and create an isosurface at value 135"

# Full pipeline
vtk-st pipeline "Read volume.vti and create an isosurface at value 135"
```

## Architecture

### High-level pipeline

```text
User Prompt
  -> ClarificationSession (optional, interactive)
  -> DecompositionSession (LLM + MCP tooling)
  -> GenerationSession (LLM + MCP + RAG)
  -> Python code output
```

### Public API (library)

The library exports three “session” entry points:

- `ClarificationSession` (prompt -> synthesized prompt)
- `DecompositionSession` (prompt -> tasks)
- `GenerationSession` (tasks -> code)

They are exported from `vtk_sequential_thinking/__init__.py` as aliases of the internal `Session` classes in each subpackage.

---

### Stage 1: Prompt clarification

Key data:

- `SessionResponse.status`: one of `clear`, `needs_clarification`, `ready_to_synthesize`, `synthesized`, `restart`, `skipped`
- `SessionResponse.prompt`: the original prompt
- `SessionResponse.questions`: pending questions (if any)
- `SessionResponse.synthesized_prompt`: only set after synthesis

Key files:

- `vtk_sequential_thinking/prompt_clarification/models.py`
- `vtk_sequential_thinking/prompt_clarification/clarifier.py`
- `vtk_sequential_thinking/prompt_clarification/session.py`

---

### Stage 2: Task decomposition

Key data:

- `Task`: `{id, task_type, description, search_query, depends_on, vtk_classes, from_prompt}`
- `DecompositionResult`: `{tasks, output_type, reasoning}`

The decomposition session supports:

- `decompose(prompt)`
- `refine(modifications, additions)`
- `finalize()`

Key files:

- `vtk_sequential_thinking/task_decomposition/models.py`
- `vtk_sequential_thinking/task_decomposition/prompts.py`
- `vtk_sequential_thinking/task_decomposition/decomposer.py`
- `vtk_sequential_thinking/task_decomposition/session.py`

---

### Stage 3: Sequential code generation

Flow:

```text
tasks[]
  -> Generator.generate(task)
     - (optional) retrieve examples via RAG
     - tool loop via MCP (VTK API grounding)
     - JSONProtocol decoding into TaskResult
  -> CodeAssembler.add_snippet(...)
  -> CodeAssembler.assemble() -> final_code
```

Output:

- `PipelineResult.code`: final assembled code
- `PipelineResult.task_results`: per-task outputs

Key files:

- `vtk_sequential_thinking/sequential_generation/session.py`
- `vtk_sequential_thinking/sequential_generation/generator.py`
- `vtk_sequential_thinking/sequential_generation/code_assembler.py`
- `vtk_sequential_thinking/sequential_generation/models.py`

---

### CLI mapping

The CLI is implemented in `vtk_sequential_thinking/cli.py` using Typer.

- `vtk-st evaluate`: clarity evaluation only
- `vtk-st query`: interactive clarification (outputs synthesized prompt)
- `vtk-st decompose`: prompt -> tasks JSON
- `vtk-st generate`: tasks JSON -> code
- `vtk-st pipeline`: clarify -> decompose -> generate

---

### Tests

Tests are split into offline-safe unit tests and CLI-level integration tests:

- `tests/unit/`
- `tests/integration/`

Many integration tests monkeypatch external clients so they can run without live services.

---

### Examples

- `examples/clarification_example.py`: clarification only
- `examples/decomposition_example.py`: decomposition/refinement only
- `examples/generation_example.py`: generation only
- `examples/pipeline_example.py`: full pipeline demonstration

## LLM providers

The LLM client supports multiple providers:

- OpenAI
- Anthropic
- Google

---

## Usage Examples

### Programmatic usage

```python
from vtk_sequential_thinking import (
    ClarificationSession,
    DecompositionSession,
    GenerationSession,
    LLMClient,
    MCPClient,
    load_config,
)

config = load_config()
llm_client = LLMClient(app_config=config)
mcp_client = MCPClient(app_config=config)

# 1) Clarify
clarify = ClarificationSession.from_config(config, llm_client=llm_client)
resp = clarify.submit_prompt("Read a VTK file and visualize it")
if resp.status != "clear":
    # In a real app, you'd iterate questions and then call synthesize()
    resp = clarify.synthesize()
synthesized_prompt = resp.prompt if resp.status == "clear" else (resp.synthesized_prompt or "")

# 2) Decompose
decomposer = DecompositionSession.from_config(config, llm_client=llm_client, mcp_client=mcp_client)
decomp = decomposer.decompose(synthesized_prompt)

# 3) Generate
generator = GenerationSession.from_config(config, llm_client=llm_client, mcp_client=mcp_client)
result = generator.generate(tasks=decomp.tasks, original_prompt=synthesized_prompt)
print(result.code)
```
