# Preflight agent specs for prompt-injection risk across prompt, tool, and architecture layers with Prompt Hardener

Describe an agent in `agent_spec.yaml`, run deterministic prompt-injection analysis, generate mitigations, and validate defenses before rollout.

## Prerequisites

Python 3, pipx or uv optional

## Installation

Use the upstream install or setup path that matches your environment:
- pipx install https://github.com/cybozu/prompt-hardener/releases/download/v0.6.0/prompt_hardener-0.6.0-py3-none-any.whl
- Recommended if you already use uv for Python tooling.
- uv tool install https://github.com/cybozu/prompt-hardener/releases/download/v0.6.0/prompt_hardener-0.6.0-py3-none-any.whl
- pip install https://github.com/cybozu/prompt-hardener/releases/download/v0.6.0/prompt_hardener-0.6.0-py3-none-any.whl

Requirements and caveats from upstream:
- **Deterministic first**: init, validate, analyze, report, and diff do not require an LLM API key
- Use this if you prefer a standard Python environment.

Basic usage or getting-started notes:
- run deterministic security analysis across prompt, tool, and architecture layers
- Choose the installation method that fits how you want to use Prompt Hardener.
- ### Using [pipx](https://pipx.pypa.io/)
