This skill ensures operations target the correct scope. --- ## Detection On session start or first file edit, check for these markers: | File | Tool | |------|------| | `pnpm-workspace.yaml` | pnpm workspaces | | `turbo.json` | Turborepo | | `nx.json` | Nx | | `lerna.json` | Lerna | | `package.json` with `"workspaces": [...]` | npm / yarn workspaces | | `Cargo.toml` with `[workspace]` | Rust workspaces | | `go.work` | Go workspaces | | `pyproject.toml` with Poetry/uv workspace config | Python workspaces | If detected → monorepo mode ON. Record in workflow state. All subsequent commands must respect package scope. --- ## Key Rules ### 1. Always identify the target package first Before any `install`, `test`, or `build`: - Which package is the change in? Full path: `packages/<name>/` - Run **scoped**, not from root: `pnpm --filter <name> test` ### 2. Cross-package changes = coordinate If a change touches package A's API used by package B: - List all consumers: `grep -r "@your-org/package-a" packages/` - Update all
