Batch Migration Orchestrator
Use this skill for sweeping refactors, migrations, bulk renames, or repetitive codebase-wide edits.
Goal
Turn one large request into a safe parallel rollout with independent units, validation, and mergeable outputs.
Workflow
- Inspect the repo to find every affected area, convention, and dependency.
- Split the change into independent units by module, directory, or subsystem.
- Define an end-to-end verification recipe for each unit.
- Launch workers in parallel only when their write scopes do not overlap.
- Track completion, collect PRs or patches, and summarize failures.
Guardrails
- Do not parallelize tightly coupled work.
- Do not let workers edit the same files.
- Require each worker to validate its own unit.
- Prefer worktree or isolated branch execution when git is available.
Inputs
- Migration target
- Scope boundaries
- Verification method
- Branch/PR expectations
