Layout Library Import and Sync Workflow

This skill guides you through importing a Google Slides presentation as a layout library, creating a master from it, and syncing content from an existing reference master.

Overview

The workflow consists of these steps:

1. Import a Google Slides presentation as a layout library
2. Create a master from the layout library
3. Match slides between the new master and a reference master
4. For each matched slide: unhide it and copy element content from the reference
5. Resolve to populate content

Step 1: Import Layout Library

Use import_layout_library to import a Google Slides presentation.

Tool: import_layout_library

Parameters:

• presentation_url (required): Google Slides URL or presentation ID
• name (required): Name for the layout library

Example:

import_layout_library(
    presentation_url="https://docs.google.com/presentation/d/1G5UFoE9U_DMtuMqeG_WQ1oWF-I4NR5AK3koAZw1ye58/edit",
    name="Q1 Report Template"
)

Returns:

• layout_library_id: Use this to create a master
• deck_id: The underlying deck ID
• slide_count: Number of slides imported

Notes:

• The presentation is copied to the user's Google Drive
• All slides and elements are automatically named using LLM
• This may take 30-60 seconds depending on presentation size

---

Step 2: Create Master from Layout Library

Use create_master to create an editable master from the layout library.

Tool: create_master

Parameters:

• layout_library_id (required): From step 1
• name (optional): Custom name for the master

Example:

create_master(
    layout_library_id=<layout_library_id from step 1>,
    name="Q1 Report Master"
)

Returns:

• master_id: Use this for all subsequent operations
• deck_id: The master's deck ID
• All slides are created hidden by default

---

Step 3: Match Slides with Reference Master

Use match_slides to find corresponding slides between your new master and a reference master.

Tool: match_slides

Parameters:

• source_doc_id (required): The new master's deck ID from step 2
• target_doc_id (required): The reference master's deck ID with existing content
• slide_name (optional): Match only a specific slide
• include_thumbnails (optional): Use thumbnail comparison (slower)

Example:

match_slides(
    source_doc_id=<new_master_deck_id>,
    target_doc_id=<reference_deck_id>
)

Returns:

• matches: List of matched slide pairs with:
  • source_slide_name: Slide in new master
  • target_slide_name: Corresponding slide in reference
  • similarity_score: 0.0-1.0 confidence score
  • match_reason: "exact_name_match" or "element_overlap"
  • element_matches: Matched elements between slides
• unmatched_source_slides: Slides in new master with no match
• unmatched_target_slides: Slides in reference with no match

Matching Algorithm:

1. Exact name match: Slides with identical names (score=1.0)
2. Element overlap: Jaccard similarity of element names (threshold: 0.3)

---

Step 4: Process Each Matched Slide

For each match, perform these operations:

4a. Unhide the Slide

update_slide(
    doc_id=<new_master_deck_id>,
    slide_name="Intro",
    hidden=false
)

4b. Copy Element Content

For each matched element pair:

copy_block(
    source={doc_id: <reference_deck_id>, slide_name: "Intro", block_name: "title"},
    target={doc_id: <new_master_deck_id>, slide_name: "Intro", block_name: "title"}
)

Notes:

• If block types differ, the target is automatically converted to match the source type while preserving its layout properties (width, height, placeholder, description)
• Templates are always copied; child queries are never copied
• For query blocks, use parent_block_name to attach the copied query to a parent block
• Target block is marked as out-of-date after copy

---

Complete Workflow

1. Import the presentation:

   import_layout_library(presentation_url="https://docs.google.com/...", name="New Template")
   

   → Record layout_library_id

2. Create master:

   create_master(layout_library_id=<library_id>, name="New Template Master")
   

   → Record master_id and deck_id

3. Match slides with reference:

   match_slides(source_doc_id=<new_deck_id>, target_doc_id=<reference_deck_id>)
   

   → Get list of matches

4. For each match: unhide the slide and copy each matched element:

   update_slide(doc_id=<new_deck_id>, slide_name=<source_slide_name>, hidden=false)
   
   copy_block(
       source={doc_id: <reference_deck_id>, slide_name: <target_slide_name>, block_name: <target_element>},
       target={doc_id: <new_deck_id>, slide_name: <source_slide_name>, block_name: <source_element>}
   )
   

   Repeat copy_block for each element match in the slide.

5. Resolve to populate content:

   resolve_master(doc_id=<new_deck_id>)

Useful Related Tools

• list_layout_libraries: List all available layout libraries
• list_masters: List all masters
• inspect_layout_library: See structure of a layout library
• inspect_document: See structure of a master or get detailed slide content
• resolve_master: Trigger resolution of outdated blocks

Error Handling

Error	Cause	Solution
"Layout library not found"	Invalid ID or no access	Verify library ID exists
"Slide not found"	Slide name doesn't exist	Use inspect_document(doc_id=...) to list slides
"Block types incompatible"	Deprecated — type conversion is now automatic	Target block is converted to match source type
"Master not found"	Invalid master ID	Use list_masters to find valid IDs

Best Practices

1. Always check matches first: Review match_slides results before copying
2. Handle unmatched slides: Decide what to do with slides that don't match
3. Templates are always copied: Templates are automatically preserved during copy
4. Resolve after copying: Call resolve_master to update content after all copies
5. Batch operations: Process all matched slides before resolving once
