Gossamer is a statically typed language with Rust-flavored syntax, Go-style goroutines, and automatic deterministic memory management. The same code runs interpreted, in a REPL, or compiled to a native binary.

It teaches the model idiomatic Gossamer rules, such as collection literal spellings, value semantics, and cohort-based concurrency, so generated code compiles correctly the first time.

Yes. The skill card follows the standard SKILL.md format, and Gossamer ships a built-in MCP server via `gos mcp` for checking, running, and explaining code.

Gossamer has no ownership transfer, borrow checker, or lifetimes; it uses reference counting with checked arena regions instead. Parameters are passed by value and callers' data is always safe.
