Sanity CMS and blog workflow

Instructions

Step 1: Load context

Read references/area-guide.md and digitaltableteur-blog/AGENTS.md.

Schema types: digitaltableteur-blog/schemaTypes/

Step 2: Publish content

npm run sanity:dev          # optional local studio preview
npm run sanity:publish      # publish + refresh manifest

Alternative: scripts/publish-from-sanity.sh

Expected: updates to nextjs-app/shared/data/blogManifest.ts and/or app/blog/postMetadata.ts.

Step 3: After publish

1. Inspect git diff for generated manifest files
2. Commit generated changes if intentional
3. Verify routes locally:

npm run dev
# /blog, /blog/[slug], /blog/authors/[slug]

Step 4: Schema changes

When editing schemaTypes/:

1. Update app TypeScript types if referenced
2. npm run sanity:dev — confirm studio loads
3. Republish sample content to validate GROQ queries

CRITICAL: never hand-edit generated manifest files.

Examples

Example 1: New blog post live

User says: "I published an article in Sanity, make it show on the site"

Actions:

1. Run npm run sanity:publish
2. Commit manifest diff if changed
3. Verify /blog/[slug] renders with correct metadata and OG image

Example 2: Author page OG wrong

User says: "Author OG uses old logo"

Actions:

1. Check app/blog/authors/[slug]/ for opengraph-image.tsx
2. Prefer profile photo; fallback to generated card
3. Remove any hardcoded logo512.png from metadata

Troubleshooting

Build fails: missing post in manifest

Cause: manifest not regenerated after CMS publish.

Solution: npm run sanity:publish or node scripts/generate-blog-manifest.mjs

Studio won't start

Cause: missing Sanity env vars or wrong project ID.

Solution: ask user to verify .env.local Sanity credentials; do not commit them.

Slug 404 after publish

Cause: post not in manifest or visibility flag excludes it.

Solution: check getVisiblePosts() / manifest entry and post status in Sanity.

Boundaries

• MUST NOT hand-edit blogManifest.ts or postMetadata.ts
• Ask before bulk delete or destructive CMS operations
