A homepage request such as “Migrate my Remix app next week to TanStack Start” selected the correct migration guide but labeled the source as “next” in the generated prompt. Reuse the existing Next.js framework matcher when choosing the source label so this request is labeled Remix.

AI review notes:
Reproduced the incorrect opening sentence in the production UI after #830. Added a regression test through the deterministic application starter that checks the Remix label and Router migration guide. Full pnpm test passed before commit; the normal commit hook also runs the repository checks.

📝 Walkthrough

The migration source detector now checks whether input matches a Next.js migration before selecting that source. A regression test verifies that Remix input containing “next week” selects the Remix migration guide and prompt.

Changes: Migration source detection

Layer / File(s)	Summary
Source matching and regression coverage src/utils/application-starter.ts, tests/application-starter-partners.test.ts	The detector skips the Next.js source unless the input matches Next.js migration criteria. The regression test checks that “next week” in Remix input still produces the Remix prompt and references the React Router migration guide.

Good catch, that wording is covered now.

AI review notes:
Added site to the shared Next.js migration matcher in e89356a. The new deterministic starter regression failed before the change and passes afterward, checking both the Next source label and migration guide. The existing Remix “next week” and multiline cases remain covered. Full pnpm test and the normal commit hooks passed. CI is rerunning on the updated head.
