The instructions your model reads when the skill loads.
Modernize an internal package without mixing mechanical moves with semantic
changes or obscuring file history. Treat packages/README.md as the authority
for the package's lifetime architecture; this skill owns only the conversion
workflow.
Read packages/README.md completely, then inspect the package, its consumers,
and comparable current packages. Confirm that the package is internal-only and
can adopt the documented single-build TypeScript and ESM contract.
Before editing:
require(), export, runtime asset and path reference.If the package has an active independent release or third-party support contract, or requires a format that conflicts with the golden path, stop and establish its support contract instead of applying this workflow mechanically. Deprecated historical npm versions do not by themselves block conversion.
Read
references/history-and-verification.md
completely before planning the commits.
Keep each commit independently valid and verify rename detection before moving on. Avoid formatting or opportunistic cleanup in the mechanical commits.

for the new path, such as test imports, build inputs and package metadata. Do
