vibe-skill

Claude orchestrates. Vibe does the heavy lifting. You review the diff, save tokens, costs and avoid hitting limits!

Claude sees only ≈500–1500 tokens per run regardless of how many file reads Vibe performs internally — massive savings on exploratory and implementation tasks.

Note that Vibe works natively with Mistral models which are capable and significantly cheaper than Claude, but Vibe can also be configured to use any other provider/model instead. Eg you can use a deepseek model with vibe tooling.

Summary:

1. User types /vibe <instruction> in Claude Code
2. Claude decomposes the task and writes a prompt
3. vibe-delegate runs Mistral Vibe in a pseudo-TTY
4. The delegate reports tool calls, token counts, and git diff --stat
5. Claude reviews the diff and summarizes the result

Why

Cost savings — Vibe's file reads and edits consume cheap delegate tokens (or whatever model you configure), not Claude tokens:

Scenario	Claude Sonnet 4.6	Mistral Medium 3.5	DeepSeek V4 Flash
Simple 1-file tweak (800 tokens)	≈$0.004	≈$0.002	≈$0.0001
6-read implementation task (4,800 tokens)	≈$0.023	≈$0.012	≈$0.0008
Complex multi-file refactor (12,000 tokens)	≈$0.058	≈$0.029	≈$0.002

Costs based on official pricing (May 2026): Claude $3/$15 per M tokens, Mistral Medium 3.5 $1.50/$7.50, DeepSeek V4 Flash $0.14/$0.28. Assumes ≈85% input / 15% output, typical for coding tasks. Claude orchestration overhead: ≈500 tokens per run (negligible).

Delegation does cost Claude tokens — writing the prompt and reading the diff back. But the real lever is context: when Claude does the work directly, every file read accumulates in its context and is re-read on every subsequent turn. When Vibe does it, none of that enters Claude's context at all. Measured breakeven: ≈4 source files touched per task. Below that, direct is cheaper. Above it, delegation wins by a growing margin (+66% at 10 files, +89% at 30 files). See handoff-probe/ECONOMICS.md for the full analysis.

Le Chat Pro users: Mistral Vibe is included in the Le Chat Pro subscription (≈$18/mo). Mistral does not publicly document the exact usage limits, but community reports suggest ≈1–1.5B tokens/month are included. Within that allowance every delegation costs $0 in API fees — cheaper than any paid model.
