Neva Language

Use this skill for changes touching *.neva or Neva code snippets.

CLI Discovery

• Use neva --help to list commands and global options.
• Use neva <command> --help before relying on a command's flags or argument contract.
• During repository development, run go run ./cmd/neva --help or go run ./cmd/neva <command> --help when a local binary is unavailable.
• neva doc [package/path] [.] <pattern> searches the bundled standard library; use it to discover existing components before adding one.

Rules

• Read docs/user/style_guide.md before editing.
• Keep edited .neva files syntactically valid.
• If syntax is uncertain, consult internal/compiler/parser/neva.g4 and nearby .neva examples before editing.
• When feasible, validate changed Neva programs by compiling or running them.
• When editing documentation or snippets, prefer a quick local compile/run check of an equivalent minimal example.
