msd-core/tests/bug-3584-runtime-slash-formatter.test.cjs

/**
 * Regression tests for bug #3584
 *
 * Runtime/user-facing strings emitted by get-shit-done/bin/lib/*.cjs hardcoded
 * the deprecated `/gsd:<cmd>` colon form (16 files, ~50 occurrences). After
 * #2808 unified GSD installs to register skills under the hyphen form
 * (`name: gsd-execute-phase`), pasting the emitted `/gsd:execute-phase` into
 * Claude Code yields `Unknown command: /gsd:execute-phase. Did you mean
 * /gsd-execute-phase?`. Codex installs require `$gsd-<cmd>` (shell-var) form.
 *
 * Fix: a runtime-aware slash formatter (`runtime-slash.cjs`) is now the single
 * source of truth for emitting `/gsd-<cmd>` (hyphen) for skills-based runtimes
 * and `$gsd-<cmd>` for Codex. Tests assert on the formatter's typed output and
 * — for the integration tests in `bug-3584-runtime-slash-emitters.test.cjs` —
 * on the structured `--json` payloads from the runtime command handlers.
