Additional notes for reviewers

Published by CobuildX AI (https://cobuildx.ai), part of the MigrateX plugin suite.

Resubmission. The earlier submission (#4572) was created without the issue-form marker, so intake never ran on it and it was closed in a batch without review. This one is filed by a maintainer of the cobuild-tech organization that owns the repository, and pins the v2.0.1 release tag plus its full commit SHA.

This is one of five sibling plugins in the same repository (ember, angular, backbone, jquery and vanillajs to React), each submitted separately.

What it adds beyond what a model does unaided, for migrating Backbone.js (including Marionette and Underscore/Handlebars templates) to React:

A structured migration workflow (full rewrite or incremental strangler-fig) that keeps resumable state in a .migration/ folder in the user's repo: unit list, route map, statuses and QA gates, so a migration can span many sessions ("continue the migration", "what's left?").
A read-only backbone-inventory agent that maps every route, component, service, data-layer piece and hidden wiring before any code changes.
A read-only backbone-parity-reviewer agent that checks each migrated piece against its original for behavior, markup, data and timing differences before the old code is removed.
A /plan command that writes a migration plan without touching app code.
The hosted Context7 MCP server (https://mcp.context7.com/mcp, no API key, no credentials) for current React docs.

No paid services, telemetry or secrets. MIT licensed. The root plugin.json follows the Agent Plugins v1.0.0 schema.
