Mistral Vibe

Mistral Vibe is an open-source terminal-based AI coding assistant developed by Mistral AI. It brings Mistral's frontier reasoning and code-specialized model ecosystem directly into local developer environments via the command line. In day-to-day operations, Mistral Vibe runs inside your terminal, interfacing with your local file tree and git repository. Developers prompt the agent to inspect files, implement features, run diagnostics, and apply code modifications. It connects to Mistral AI endpoints to leverage models such as Codestral and Mistral Large, executing actions through an extensible skills framework. What sets Mistral Vibe apart is its first-party alignment with the Mistral ecosystem and its support for modular agent skills defined directly within repositories. It offers a lightweight, transparent alternative to heavy proprietary coding assistants, giving teams full visibility over agent behavior and direct access to Mistral-optimized prompting architectures. The project is open source and hosted on GitHub. Model execution requires a Mistral API key for hosted inference or access to compatible endpoints.

Key features

• Native Mistral Integration — Directly configured to run with Mistral AI models including Codestral and Mistral Large. - Modular Agent Skills — Supports configurable, repository-level skills located in .agents/skills for custom tasks and behaviors. - Terminal-Native Workflow — Operates entirely from the command line without requiring a dedicated IDE plugin. - Context-Aware File Editing — Inspects local files, generates targeted diffs, and applies updates directly across projects. - Open-Source Foundation — Community-driven codebase on GitHub with frequent release cycles and active issue tracking.

Use cases

Use Case: Codebase Refactoring and Feature Implementation A developer uses Mistral Vibe in the terminal to request multi-file refactoring or new feature stubs using Codestral. The agent analyzes local repository context, drafts required changes, and applies clean edits across multiple files.

Use Case: Fast Bug Localization and Patching When an error or failing test occurs, the engineer passes the stack trace to Mistral Vibe in the CLI. The agent locates the relevant source files, explains the root cause, and applies the necessary code fix directly in place.

Use Case: Custom Workflow Automation with Agent Skills A team configures custom agent skills inside their repository to standardize tasks like documentation generation, schema validation, or API route scaffolding, executing them consistently via Mistral Vibe.

Who it is for

Mistral Vibe is designed for software engineers, DevOps practitioners, and teams committed to or experimenting with the Mistral AI model family who prefer terminal-first workflows. It is less suitable for developers who require tightly integrated graphical IDE extensions or teams strictly standardized on closed third-party agent harnesses.

Install guide

Installation Install Mistral Vibe directly from source or via the standard package manager: bash git clone https://github.com/mistralai/mistral-vibe.git cd mistral-vibe pip install -e .

First Run Configure your Mistral AI API credentials before launching the assistant: bash export MISTRAL_API_KEY="your_mistral_api_key_here" vibe

Example Session Run Mistral Vibe inside your project directory to inspect and modify code: bash vibe "Inspect src/auth.py and add JWT token expiration validation with unit tests in tests/test_auth.py"
