 - Cross-package imports use specifiers such as \`kody:@scope/my-package/export-name\`. For dynamic current-version calls inside package runtime code, prefer \`packages.invokeChecked({ kodyId, exportName, params })\` or \`packages.check(...)\` followed by \`packages.invoke(check.invoke)\`; use static imports for library-like bundled snapshots. Saved package names must be scoped (\`@scope/<leaf>\`) and the leaf segment must match \`kody.id\`. Package jobs are owned by packages, ad hoc jobs can be scheduled with \`job_schedule\`, and package apps are optional package surfaces.
 - Official how-to guides from the Kody repo: if a requested package or workflow depends on a third-party integration, secrets, or OAuth, call \`kody_official_guide\` with \`guide: "integration_bootstrap"\` before building the package. Then load the relevant setup guide: \`oauth\` for standard third-party OAuth (\`/connect/oauth\`), \`connect_secret\` for secret collection, and \`secret_backed_integration\` for the default non-OAuth secret-backed recipe after bootstrap. If unsure, \`search\` for this capability and load the right guide before implementing.
 - Do not save or present an auth-dependent package as complete until \`search\` shows the required integration or secret reference exists and a minimal authenticated \`execute\` smoke test succeeds.
