Skill Vibe

Vibe CLI Integration for Claude Code

Delegate simple coding tasks from Claude Code to Mistral Vibe CLI (powered by Devstral 2.1) for cost-efficient execution.

Purpose

Enable Claude Code to invoke the Vibe CLI (vibe --prompt) for automated code generation, refactoring, test scaffolding, and other mechanical coding workflows — saving Claude tokens for tasks that actually need them.

Prerequisites

• vibe CLI installed and available on PATH
• Mistral API key configured in ~/.vibe/.env or as MISTRAL_API_KEY env var
• Confirm the installation by running vibe --version; resolve any errors before using the skill

Install Vibe CLI

curl -LsSf https://mistral.ai/vibe/install.sh | bash

Installation

Option 1: Standalone Skill Installation

git clone --depth 1 https://github.com/kharonsec/vibe-plugin.git /tmp/skill-vibe-tmp && \
mkdir -p ~/.claude/skills && \
cp -r /tmp/skill-vibe-tmp/plugins/skill-vibe/skills/vibe ~/.claude/skills/vibe && \
rm -rf /tmp/skill-vibe-tmp

Option 2: Plugin Installation

If Claude Code's plugin marketplace is available:

/plugin marketplace add kharonsec/vibe-plugin
/plugin install skill-vibe@vibe-plugin

Usage

Automatic delegation

Claude Code will automatically delegate simple tasks to Vibe when the skill is installed. Tasks like boilerplate generation, simple refactors, test scaffolding, and documentation updates will be routed to Devstral 2.1 via the Vibe CLI.

Explicit delegation

You can explicitly ask Claude to use Vibe:

Use vibe to add JSDoc comments to all files in src/utils/

Thinking tokens

By default, Vibe's thinking tokens (stderr) are suppressed with 2>/dev/null to avoid bloating Claude Code's context window. If you want to see them for debugging, ask Claude to show Vibe's thinking output.

Cost

Devstral 2.1 API pricing: $0.40/M input tokens, $2.00/M output tokens. Typical simple tasks cost $0.01-0.10 — significantly cheaper than using Claude for mechanical work.

How It Works

1. You give Claude Code a task
2. Claude evaluates if the task is simple enough to delegate
3. Claude constructs a specific prompt and runs vibe --prompt "..." --max-turns N --max-price $X
4. Vibe executes the task using Devstral 2.1
5. Claude reads the output, verifies the changes, and summarizes results
6. If Vibe fails, Claude falls back to handling it directly
