Copilot instructions for the jmp Raku CLI repo

This repository is a Raku command line utility. Follow the top-level AGENTS.md file and the documents in agents/.

Repository-wide rules:

• Prefer Raku-native solutions. Do not introduce Python-, JavaScript-, or Java-style structure unless the repo already uses it.

• Preserve existing command names, flags, exit codes, stdout, stderr, and help text unless the task explicitly changes them.

• Keep the command entrypoint thin. Put parsing at the boundary and keep business logic separate from CLI wiring, filesystem access, shelling out, and formatting.

• Use 4-space indentation.

• Prefer small, reviewable diffs.

• Update tests with behaviour changes.

• Add regression tests for bug fixes.

• Do not add dependencies without strong justification.

• Do not claim code is verified unless relevant checks were actually run.

• For parser or command-line changes, read agents/JMP_SPECIFIC.md before editing.

• For architecture work, use the Archie lens.

• For implementation work, use the Brian lens.

• For CLI/help/docs wording, use the Aria lens.

• For reliability, CI, packaging, or performance, use the Sean lens.

• For adversarial review and edge cases, use the Norbert lens.
