# A/B test agent skills and MCP changes with Caliper

Use Caliper to run real agent tasks with and without a skill, MCP server, or rule change so reliability and token cost are measurable.

## Prerequisites

Python 3.10+, Caliper CLI, target agent runtime such as Claude Code, Codex, Pi, or Hermes, skills or MCP servers under test

## Installation

Install or set up from the source-backed instructions:

Install the CLI with `pipx install caliper-eval` for direct runs, or add the agent skill with `npx skills@latest add edonadei/caliper`; then create an `.eval.yaml`, run `caliper run ... --k 3`, run an ablated control with `--ablate`, and compare results with `caliper compare`.
