A delegation skill that sends straightforward coding work to the Mistral Vibe command-line tool, an external coding agent powered by Devstral 2.1.

Use it for simple refactors, boilerplate, test scaffolding, documentation updates, and similar clearly specified file changes.

It can handle well-defined, mechanical work while leaving more complex reasoning to the main agent, provided Vibe is installed and configured.

Getting it into your agent

One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Model	Per session	Once invoked
Fable 5	$0.00133	$0.01811
Opus 5	$0.00067	$0.00905
Sonnet 5	$0.00027	$0.00362
Haiku 4.5	$0.00013	$0.00181

Security

Grade C, and why

vibe scanned grade C with 2 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 3d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Mistral Vibe CLI Delegation Skill

Delegate simple, well-defined coding tasks to Mistral's Vibe CLI agent (powered by Devstral 2.1) to save Claude tokens for harder problems. Vibe runs non-interactively via --prompt and returns results that Claude summarizes for the user.

Prerequisites

vibe CLI installed and on PATH (install: curl -LsSf https://mistral.ai/vibe/install.sh | bash)
Mistral API key configured (~/.vibe/.env or MISTRAL_API_KEY env var)
Confirm installation: vibe --version; resolve any errors before using this skill

If vibe is not installed or not configured, inform the user and provide the installation instructions above. Do NOT attempt to run vibe commands if the prerequisites are not met.

How It Works

Claude evaluates the user's request
If the task is simple/mechanical, Claude delegates to Vibe via a shell command
Vibe runs non-interactively with --prompt, auto-approving tool executions
Claude reads the output and summarizes results back to the user
If Vibe's output is insufficient or incorrect, Claude can either retry with a refined prompt or fall back to handling the task itself

Task Routing Guidelines

Delegate to Vibe (cheap, fast)

Boilerplate generation (new files, structs, interfaces, CRUD endpoints)
Simple refactors (rename, extract function, move code between files)
Test scaffolding and simple test writing
Documentation and comment generation
Formatting, linting fixes, import sorting
Dependency version bumps
Mechanical find-and-replace across files
Adding error handling to straightforward functions
Generating type definitions or interfaces from existing code
Simple bug fixes where the issue is clearly identified

Keep in Claude (complex, nuanced)

Architectural decisions or design pattern selection
Security-sensitive code review or vulnerability analysis
Complex multi-step debugging requiring deep reasoning
Performance optimization requiring profiling analysis
Tasks requiring understanding of the full project context across many files
Anything the user explicitly wants Claude to handle

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

vibe is a skill published in the GitHub repository kharonsec/vibe-plugin (4 stars, last pushed 5mo ago), licensed MIT. It adds 133 tokens to every session and 1,811 once invoked, about $0.0007 per session on Opus 5. A static security scan graded it C with 2 findings (downloads and executes remote code, makes network calls). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
