ferritin
ferritin is a Go, Rust & systems languages skill for AI agents, published by jbr in the ferritin repository on GitHub. Skillspace rates ferritin D (55/100) and it passed the safety scan; the rating is based on static analysis only.
Look up real Rust documentation with the `ferritin` CLI instead of guessing APIs from memory. Use whenever you need a crate's types, traits, methods, function signatures, or module contents — for dependencies, the standard library, or local workspace crates. Reach for it before answering any Rust API question ("what methods does X have", "how do I use Y", "what's the signature of Z", "does this trait require..."), and when writing or reviewing Rust against an unfamiliar API. Runs as a plain shell command; no MCP server.
