tiesta 0.1.2

Tiesta — Local AI Coding Assistant powered by Ollama

Tiesta: Your AI Engineering Companion

A fully autonomous, 100% local, VRAM-efficient AI agent powered by Ollama.

---

Tiesta is not just an agent; it's your second engineer. It goes beyond simple autocomplete or conversational chatbots. Tiesta is a true companion who actively explores your codebase, autonomously executes terminal commands, resolves compilation errors, and, when finished, politely asks: "I've finished my part, what's next?"

Designed from the ground up to run entirely locally, Tiesta empowers developers to build, refactor, and debug complex applications with zero data privacy concerns and absolute flexibility.

🎉 What's New in v0.1.1

• Autonomous Environment Management: Tiesta now autonomously manages its own dependencies! If your local Ollama daemon is not running, Tiesta will seamlessly spin it up in the background (with full Windows compatibility) without crashing.
• Network Patch: Patched IPv6/DNS resolution errors on Windows by enforcing strict 127.0.0.1 IPv4 mapping.

🌟 Features

• 100% Local & Private: No external API calls. Your code never leaves your machine. Powered natively by Ollama.
• Bring Your Own Model (BYOM): During onboarding, dynamically discover and select any Ollama model installed on your system. Highly optimized for qwen2.5-coder:3b for ultra-fast, low-VRAM execution.
• Hardware-in-the-Loop: A killer feature for embedded systems. Tiesta can autonomously scan active serial ports and read hardware logs (ESP32, ROS 2, Arduino) to instantly debug your hardware and patch the corresponding Python/C++ code.
• Unified Permission Control Plane: An elegant Rich-powered UI intercepts and gates destructive terminal commands (rm, massive code deletions), ensuring absolute human oversight before modifying your system.
• Polyglot Linter: Validates syntax proactively. If Tiesta makes a syntax error in Python, JavaScript, C++, Rust, or Dart, it will instantly catch the traceback and self-correct without bothering you.
• Dynamic Architecture Maps: Automatically generates and updates Mermaid.js visual maps (TIESTA_ARCHITECTURE.md), allowing the agent to see your project structurally while providing human-readable documentation.
• Zero-Dependency Semantic RAG: Instead of relying on heavy tree-sitter C-bindings, Tiesta uses a highly efficient, regex-powered semantic chunking system to precisely locate symbols, classes, and variables.
• LSP Integration: Built on jedi, it understands your code context natively (go to definition, find usages) without spinning up a heavy background language server.

🚀 Getting Started

Prerequisites

1. Install Ollama and ensure the daemon is running.
2. Pull the recommended default model (or any model of your choice):

   ollama pull qwen2.5-coder:3b
   

Installation

Install Tiesta globally via PyPI:

pip install tiesta

Quickstart

Run Tiesta interactively in your current project directory:

tiesta

On the very first run, Tiesta's Onboarding Wizard will automatically launch to detect your installed Ollama models and set up your preferred environment.

You can also run one-shot tasks directly from the terminal:

tiesta "Refactor the user authentication logic in core/auth.py"

🧠 How it Works

Tiesta employs a sophisticated "Precision Coding Protocol" via a customized Agentic Execution Loop (The Orchestrator):

1. Context Loading: Tiesta silently loads a lightweight Zero-Shot workspace awareness map (directory trees, git statuses, architecture graphs).
2. Decomposition: It forces the underlying LLM to think step-by-step and enumerate a checklist of sub-tasks.
3. Execution & Self-Correction: Tiesta executes tools natively in a sandboxed environment. If a compilation error or git conflict occurs, the Orchestrator autonomously feeds the traceback back to the LLM to self-correct up to 3 times before asking for human help.
4. Result Verification: Before rendering the final response to the user, the agent cross-verifies its output against its internal checklist to guarantee completeness.
