Sanity CMS Skill

Publishes documents to Sanity CMS via the Content API. Works with any schema.

References

• API patterns (upload, mutate, query): references/api.md
• Portable Text body format: references/portable-text.md

Workflow

1. Understand the target schema

Four ways to get schema info — try in this order:

A — File in workspace: User drops schema at a known path (e.g. sanity-schemas/blogPost.ts). Read it directly.

B — Pasted in chat: User pastes the schema TypeScript/JS. Read it from the conversation.

C — Remote URL: User shares a GitHub raw URL or similar. Fetch with web_fetch.

D — API introspection (no file needed): Query the dataset directly — see references/api.md (Schema Introspection section). Use array::unique(*[]._type) to discover document types, then fetch one sample document to infer field names and shapes. Works without any schema file at all.

Once you have the schema (by any method):

• For array fields with type: 'block', use Portable Text format — see references/portable-text.md
• For reference fields (categories, authors, tags), query existing documents via GROQ — see references/api.md

2. Format the document JSON

Build a JSON object matching the schema:

• Omit _id — the script generates a drafts. prefixed UUID automatically
• Omit the cover image field — the script injects it after uploading
• All required fields must be present and within any validation constraints
• Save to a logical path (e.g. brain/projects/<slug>-sanity.json or similar)

3. Run the publish script

The script is at scripts/publish_draft.sh within this skill directory. Resolve the path relative to where the skill is installed (e.g. ~/.openclaw/skills/sanity-cms/scripts/publish_draft.sh or <workspace>/skills/sanity-cms/scripts/publish_draft.sh).

bash <skill-dir>/scripts/publish_draft.sh \
  path/to/document.json \
  path/to/cover-image.png   # optional

Optional env overrides:

Example with overrides:

SANITY_DATASET=staging COVER_IMAGE_FIELD=mainImage \
  bash <skill-dir>/scripts/publish_draft.sh doc.json cover.jpg

4. Confirm and report

After the script prints a draft ID, report to the user:

• The draft document ID
• A link to Sanity Studio (ask if unsure of the Studio URL)
• Which fields, if any, still need manual attention in Studio (e.g. unpopulated references)

Env Vars

Tips

• Always create drafts first (DRAFT_PREFIX=true) unless the user explicitly wants to publish live
• If a schema has reference fields, query for the referenced document IDs via GROQ before building the JSON — see references/api.md
• The script works with any document type: blog posts, pages, products, authors, etc.
• Cover image upload is optional — omit the second argument if the schema has no image field
