# KYE™ framework adapters

Thin wrappers so popular agent / RAG / data frameworks emit the KYE™ §0.3 governance + evidence envelopes for free. Each adapter reuses the SAME envelope shape as the [Agent Dev Kit™ templates](https://kyeprotocol.com/oss/agent-dev-kit-templates/) (§32) — KYE™ **governs** the framework as a principal (§0.30); it never runs, replaces, or vendors it. The non-competition lock vs LangChain / LlamaIndex / CrewAI / Firecrawl / CocoIndex is permanent.

[langchain A BaseCallbackHandler that emits the governance + completion envelopes around every LangChain chain / agent run.](https://oss.kyeprotocol.com/framework-adapters/langchain/README.md) [llamaindex A retrieval callback that seals each LlamaIndex query / retrieval as a KYE™ tool-call inside the evidence chain.](https://oss.kyeprotocol.com/framework-adapters/llamaindex/README.md) [crewai A step callback that binds a CrewAI crew at kickoff and records each agent task as a KYE™ tool-call.](https://oss.kyeprotocol.com/framework-adapters/crewai/README.md) [firecrawl A scrape wrapper that seals each Firecrawl crawl / scrape as a KYE™ tool-call with the source URL pinned.](https://oss.kyeprotocol.com/framework-adapters/firecrawl/README.md) [cocoindex A flow hook that records each CocoIndex transform / index update as a KYE™ tool-call in the evidence chain.](https://oss.kyeprotocol.com/framework-adapters/cocoindex/README.md) [haystack KYE™ Authority Components for a Haystack pipeline — a signed agent manifest, a tool-call admissibility gate that runs the real tool only on allow, sub-agent attenuation, a RAG reliance record, and an evidence pack. The framework decides what to do; KYE™ decides whether it was allowed to.](https://oss.kyeprotocol.com/framework-adapters/haystack/README.md) [pgvector A retrieval Data-Admissibility gate that sits in front of a customer's pgvector query and binds retrieved context to purpose + authority before it feeds an agent action. Retrieval is not authority; recall is not a mandate.](https://oss.kyeprotocol.com/framework-adapters/pgvector/README.md)
