Introduction

Prompt Hardener analyzes prompt-injection risk from agent_spec.yaml, exports reports, and can simulate adversarial attacks with API keys.

Best for: agent builders who want a repeatable security checklist for prompts/tools/architecture

Works with: Python, pipx/uv, YAML specs, CI pipelines (Markdown/HTML/JSON outputs)

Setup time: 8-15 minutes

Key facts (verified)

  • GitHub: 51 stars · 7 forks · pushed 2026-05-12.
  • License: Apache-2.0 · owner avatar + repo URL verified via GitHub API.
  • README-verified entrypoint: pipx install https://github.com/cybozu/prompt-hardener/releases/download/v0.6.0/prompt_hardener-0.6.0-py3-none-any.whl.

Main

  • Start deterministic: validate + analyze give you a static run without any LLM API key (per README).

  • When you want to test defenses, use simulate on a hardened spec to run adversarial scenarios (README notes this is LLM-backed).

  • Treat the output as CI artifacts: export Markdown/HTML/JSON and diff runs over time to track regressions.

Source-backed notes

  • README describes a single workflow driven by agent_spec.yaml and supports exports as Markdown/HTML/JSON.
  • README quick start copies an example spec and runs prompt-hardener validate and prompt-hardener analyze without API keys.
  • README lists which commands require API keys (simulate yes; many others no).

FAQ

  • Do I need an API key for analysis?: No — README says validate/analyze are deterministic and do not require keys.
  • What file do I write?: An agent_spec.yaml describing your system, as shown in the README examples.
  • Can I export a report?: Yes — report renders JSON results to HTML/Markdown/JSON per README.
