Rail Setup

Scaffold per-repo configuration that rail engineering skills assume:

Everything under docs/monorail/ — work tracker, glossary, ADRs, and convention files (no remote tracker; no scatter to repo root / docs/agents/ / docs/adr/)
Domain docs — docs/monorail/CONTEXT.md + docs/monorail/adr/

This is prompt-driven, not a deterministic script. Explore, present, then write — never pause to ask the user to confirm the plan.

Process

Read what exists; do not assume:

AGENTS.md / CLAUDE.md — either present? Already has ## Agent skills?
docs/monorail/ — already in use? Check with the shell (ls -R docs/monorail, or ls / test -f per file): work-tracker.md / domain.md / CONTEXT.md / adr/. Search tools skip gitignored paths — an empty Glob/Grep result is not evidence the directory is unused
Legacy scatter (migrate hint only, do not auto-move): repo-root CONTEXT.md / CONTEXT-MAP.md, docs/adr/, docs/agents/
Monorepo signals (pnpm-workspace.yaml, package workspaces, populated packages/*)
