↻ Runs by itselfNightly during migration
How the habit works.
You don't have to.
When does it start? How does it check its work? What does it remember?
One run, step by step.
Then it stops.
Stops after one full rerun per night, with 1 retry on a failed import.
- 01
Read the guides
The agent reads references/general.md and the guide for the source platform.
- 02
Plan
It keeps a short plan for access, scope, schema, extraction, transform, import, validation, redirects and cutover.
- 03
Stop and ask
It asks you before coding when access, target dataset, scope, media or schema is unclear.
- 04
Snapshot
It saves the extracted source data to disk before transforming it.
- 05
Transform and import
It converts rich text to Portable Text and imports with stable IDs via createOrReplace, createIfNotExists or sanity datasets import --replace.
- 06
Validate
It runs count, sample, reference and redirect checks and updates the validation summary.
What it may do.
Nothing more.
It writes only in its own folder and asks you before anything goes out.
- Writes only inmigration scripts folder, source snapshot folder, loops/sanity-migration-rerun-loop/**
- Talks tothe source CMS API, the target Sanity project
- Sendsnothing
- Your OKIt asks you before anything goes out.

Skip it when
- – You already run on Sanity with no import
- – You only change one document
Sanity Migration skill, answered.
Why stable IDs?
IDs from source IDs, slugs, paths or hashes let reruns overwrite instead of duplicate.
Can it use MCP content tools for bulk import?
No. The skill wants NDJSON or scripts for bulk work.
Which sources are covered?
AEM, Contentful, Strapi, Webflow, WordPress, Payload, Drupal and Markdown, with general.md for the rest.
