Introduce `runtime-slash.cjs` as the single source of truth for emitting
GSD slash-command references in user-facing runtime output and persisted
artifacts. `formatGsdSlash(commandName, runtime)` produces `/gsd-<cmd>`
for skills-based runtimes (Claude/Cursor/OpenCode/Kilo/etc.) and
`$gsd-<cmd>` for Codex. The deprecated `/gsd:<cmd>` colon form is never
emitted — pasting a recommended-action command into Claude Code now
routes correctly instead of failing with `Unknown command`.
Wired into the high-impact emitters identified in #3584:
- `init.cjs` `cmdInitManager` recommended_actions[].command (the
original failure path in the bug report) plus the no-ROADMAP /
no-STATE error hints.
- `phase.cjs` `cmdPhaseAdd`, `cmdPhaseAddBatch`, `cmdPhaseInsert` —
ROADMAP.md `Plans:` references now persist the routable form
instead of the legacy colon form.
- `verify.cjs` `cmdValidateHealth` — every fix-hint addIssue() call
(E001/E002/E003/E004/E005, W002/W003/W008/W009/W011/W016/W018) and
the persisted STATE.md regenerate / MILESTONES.md backfill notes.
- `milestone.cjs` `cmdMilestoneComplete` — Operator Next Steps tail
rewrite.
- `validate-command-router.cjs` — `validate context` recommendation
strings for WARNING/CRITICAL utilization bands.
- `workstream.cjs` — missing .planning hint.
- `profile-output.cjs` — `generate-claude-md` workflow enforcement
block, project/skills fallbacks, profile placeholder, and the
dev-preferences refresh hints.
- `drift.cjs`, `gsd2-import.cjs`, `commands.cjs scaffold context` —
remaining one-off persisted references.
Runtime detection: `resolveRuntime(projectDir)` reads
`process.env.GSD_RUNTIME` first, then a side-effect-free direct read of
`.planning/config.json` (NOT `loadConfig`, which would normalize legacy
keys and re-write the file just to read the runtime name).
Tests:
- `tests/bug-3584-runtime-slash-formatter.test.cjs` — 22 unit tests
covering the pure formatter and resolver (hyphen vs codex, prefix
normalization, defensive returns, env/config/default chain).
- `tests/bug-3584-runtime-slash-emitters.test.cjs` — 6 integration
tests exercising `init manager`, `phase add` (via the structured
`roadmap get-phase` payload to avoid raw-text matching on the
on-disk artifact), `validate health`, `validate context`, and the
codex variant.
- Existing tests updated to assert the new contract: validate-context
recommendations, claude-md workflow block, milestone complete
Operator Next Steps. Copilot-install engine-conversion test now
asserts against a synthetic input since bin/lib/*.cjs no longer
contains literal `/gsd:` references for the install-time converter
to rewrite.
INVENTORY.md and INVENTORY-MANIFEST.json updated for the new module
(64 CLI modules shipped, +1).
