Improved internal package migration workflow - #30524
Conversation
Prevent normal squash or rebase merges from discarding imported package ancestry by requiring a warning title, a prominent PR notice, and copyable guarded merge instructions in every handoff.
no ref\n\nKeep the migration workflow aligned with the repository bootstrap rename so it cannot invoke pnpm's shell-configuration command by accident.

WalkthroughThe migration skill now links to a dedicated migration guide. It adds workspace, submodule, blame-ignore, lockfile, formatting, archive, and record checks. The workflow preserves source dependency versions with scoped overrides when required. Migration pull requests must retain Merge Risk: 🟡 Moderate · up to The migration workflow adds important safeguards, but ambiguous handoff commands or a confirmation not demonstrably tied to the reviewed PR head could allow an administrator to merge unreviewed history.

- Around line 162-163: Add fail-closed preflight validation in merge-history-pr
for the required “[Don't merge]” title marker and warning text in the PR body,
and run it before changing repository settings or honoring --confirm. Preserve
the existing guard wording and block execution when either requirement is
absent; alternatively, explicitly document the guard as manual and non-enforced.
In @.agents/skills/migrate-internal-package/references/legacy-integration.md:
- Around line 110-111: Add the write-mode pnpm exec oxfmt packages/<package>
command before the existing formatting checks in the documented workflow, while
preserving both validation commands unchanged.
In @.agents/skills/migrate-internal-package/SKILL.md:
- Around line 44-49: Update the migrate-internal-package skill’s fresh-worktree
setup instructions to use the repository’s existing workflow instead of
undefined pnpm bootstrap, while preserving installation, submodule
initialization, and blame-ignore configuration; alternatively, add a root
package script named bootstrap that performs those steps and keep the skill’s
command consistent with it.

no ref\n\nMake the workflow discoverable to engineers starting from the codebase documentation and frame it around moving an SDK or framework package, the skill's expected output, and the exceptional merge process.
no ref\n\nAutomate package preparation and read-only validation while reserving the temporary repository setting change and exceptional merge for an explicitly identified human administrator.
no ref\n\nKeep the package migration automation available to every contributor while isolating repository administration permission to the short history-preserving merge handoff.
no ref The administrator merge checkpoint must operate on the exact PR head the contributor reviewed, and imported legacy files need the repository formatter applied before its formatting gates are checked.
