Local command
uvx tar-engine==0.3.3Credentials from the publisher
- TAR_ENGINE_URL — Override the audit backend. Default is the hosted playground at https://tarai.dev. Set to http://localhost:8765 (or your own tar-engine deployment) to self-host and keep SKILL.md content on your machine.
- TAR_ENGINE_BYOK_OPENAI_KEY — OpenAI API key that unlocks the semantic LLM and adversarial prompt-fuzz layers. Static and supply-chain layers run without it.
- TAR_ENGINE_BYOK_ANTHROPIC_KEY — Anthropic API key alternative to the OpenAI key for the semantic and adversarial layers.
