What an agent uses it for
An agent working on crypto for constrained/embedded targets queries this for libhydrogen's small, hard-to-misuse C API covering hashing, AEAD, signatures and key exchange.
curl -fsSLO https://raw.githubusercontent.com/xerj-org/xerj/corpus-hub/tools/xerj-code/hub/libhydrogen.jsonxerj corpus add --from ./libhydrogen.jsonxerj corpus index libhydrogen then xerj code libhydrogen "your question"Needs the xerj CLI and a local node running; the copy prompt covers both, checks each step, and shows how to stop only the node you started. No shell: the MCP tool xerj_code_search with corpus: "libhydrogen", once the corpus is indexed on the node.
