Documented steps
Target one package by name: pnpm --filter "@scope/pkg" test (scope can be omitted if unambiguous); glob patterns work too: --filter "@babel/*".
Use ellipsis for graph selection: --filter "foo..." = foo plus all its dependencies; --filter "...foo" = foo plus all packages that depend on it; add ^ to exclude foo itself ("foo^..." = dependencies only, "...^foo" = dependents only).
Select by directory: --filter "./packages/**" includes all projects under that path; combine with relations via --filter "...{./packages/ui}".
Select only packages changed since a commit/branch: --filter "[origin/main]"; combine with ellipsis to also run their dependents: --filter "...[origin/main]" — the standard 'test what my PR affects' invocation.
Exclude with a leading !: --filter "!foo" or --filter "!./lib". Stack multiple filters in one command: pnpm --filter ...foo --filter bar test.

Known gotchas
In zsh, ! must be escaped (\!) — unescaped it triggers shell history expansion.
--filter-prod behaves like --filter but ignores devDependencies when walking the graph — dependents linked only via devDependencies won't be selected.
Changed-detection can be tuned: --changed-files-ignore-pattern excludes files (e.g. docs) from marking a package changed, and --test-pattern lets changes that only touch test files skip dependents.
A filter that matches nothing succeeds silently by default — add --fail-if-no-match to make typos fail the CI step.
