## Summary
Adds an unlisted migration guide at `/langsmith/smithdb-sdk-migration`
for partner customers migrating from v1 SDK methods to SmithDB-backed
equivalents. The page is `noindex: true` and not wired into `docs.json`
nav — accessible via direct URL only.
Each method's content (parameter tables, examples, and their code-sample
imports) lives in its own file under
`src/snippets/langsmith/smithdb-migration/` (e.g. `runs-query.mdx`,
`runs-retrieve.mdx`), included into the main page via Mintlify's
snippet-import pattern. Adding a new method's migration guide only
requires a new snippet file plus one import and one render line in the
main page, so different teams can add methods in parallel without
conflicting.
The code-samples generation and testing pipeline was extended to support
Go and cURL/bash, alongside existing Python/TypeScript/Java/Kotlin
support, so every code sample in this guide is a real, tested source
file rather than hand-authored prose.
