Specifics

utils::package_manager_exec() auto-detects pnpm/yarn/npm -- JS modules should use this instead of hardcoding a package manager
lint_cmd.rs is a cross-ecosystem router: detects Python projects and delegates to mypy_cmd or ruff_cmd
vitest_cmd.rs uses the parser/ module for structured output parsing
playwright_cmd.rs uses the parser/ module for test result extraction
ng_cmd.rs compacts recognized Angular ng build table padding and the redundant initial progress pair. It keeps every bundle, size, build status, output location, and diagnostic; stderr is never capped. The native ng on PATH and arguments are preserved, without package-manager fallback. --help, --verbose, --watch (including explicit false values), and other subcommands pass through with inherited stdio. Only confidently parsed local workspaces using standard Angular application builders are captured. Workspaces with watch: true anywhere, JSONC/unreadable/unknown configuration, unknown builders, or no local workspace pass through conservatively. This safety check reads the nearest workspace only after build dispatch, never in the rewrite hot path. Only bare ng build is auto-rewritten; wrappers, path-based invocations, test, and serve are outside this filter's scope. Real Angular 22.2.1 fixtures live in tests/fixtures/ng_build/.

lint_cmd routes to cmds/python/mypy_cmd and cmds/python/ruff_cmd for Python projects
prettier_cmd is also called by cmds/system/format_cmd as a format dispatcher target
