Notion Manage Content

Notion: Manage Page Content

When to Activate

• User asks to update, edit, refactor, append, or insert into an existing Notion page
• User wants to delete specific blocks or override/replace a page's content
• User references "that page", "the doc", "the notes", or an existing workspace artifact
• User wants to restructure sections, rewrite content, or add new information
• Content is large or complex enough to warrant a new dedicated page

Core Rules

• Never assume page IDs. Discover first.
• Never write blind. Read current content before editing.
• Prefer markdown workflows for text/lists/headings/tables:
  • Read: NOTION_FETCH_PAGE_AS_MARKDOWN
  • Write/append: NOTION_INSERT_MARKDOWN (supports full markdown including tables)
• Avoid destructive edits unless the user explicitly asks (deleting blocks, overwriting large sections, moving/archiving).
• If the content to add is substantial and self-contained (e.g., a full report, meeting notes, reference doc), consider creating a new sub-page and linking it in the parent (see "When to Create a New Page" below).

If the user wants to change page metadata (title/properties), use NOTION_UPDATE_PAGE. If the user wants to move a page, use NOTION_MOVE_PAGE.

Workflow

Step 1: Discover the Target

NOTION_FETCH_DATA(fetch_type="pages", page_size=50)
NOTION_FETCH_DATA(fetch_type="pages", query="<keywords>", page_size=50)

If multiple plausible pages exist, present the best 2-3 (title + parent + last edited) and ask ONE focused question.

Step 2: Read Current Content

NOTION_FETCH_PAGE_AS_MARKDOWN(page_id="<uuid>")

Identify:

• existing structure (headings, block IDs)
• where new content should be inserted
• any tone/formatting constraints

To get block IDs for precise positioning:

NOTION_FETCH_BLOCK_CONTENTS(block_id="<page_id>")         # first-level children
NOTION_FETCH_ALL_BLOCK_CONTENTS(block_id="<page_id>")     # full recursive tree

Step 3: Plan the Change

Write a short plan:

• what section to add/edit
• what to preserve
• whether appending, inserting after a block, updating in-place, or replacing

Operations Reference

Append / Insert Content

General markdown content (text, headings, lists, checkboxes):

NOTION_INSERT_MARKDOWN(
  parent_block_id="<page_or_block_id>",
  markdown="## Section Title\n- Item one\n- Item two\n- [ ] Task"
)

Insert AFTER a specific block (use block ID from NOTION_FETCH_BLOCK_CONTENTS):

NOTION_INSERT_MARKDOWN(
  parent_block_id="<page_id>",
  after="<block_id_to_insert_after>",
  markdown="New content here"
)

Bulk content (multiple blocks, large inserts):

NOTION_ADD_MULTIPLE_PAGE_CONTENT(
  parent_block_id="<page_id>",
  content_blocks=[
    {"content": "First paragraph", "block_property": "paragraph"},
    {"content": "## New Heading", "block_property": "heading_2"},
    {"content": "List item", "block_property": "bulleted_list_item"}
  ]
)

Specialized block types:

NOTION_APPEND_TEXT_BLOCKS(...)      # paragraphs, headings, lists
NOTION_APPEND_TASK_BLOCKS(...)      # to-do checkboxes, toggles, callouts
NOTION_APPEND_CODE_BLOCKS(...)      # code snippets, quotes, equations
NOTION_APPEND_MEDIA_BLOCKS(...)     # images, videos, audio, embeds, bookmarks
NOTION_APPEND_LAYOUT_BLOCKS(...)    # dividers, TOC, columns

Tables

Use markdown table syntax directly — NOTION_INSERT_MARKDOWN automatically converts it to a proper Notion table via NOTION_APPEND_TABLE_BLOCKS under the hood:

NOTION_INSERT_MARKDOWN(
  parent_block_id="<page_id>",
  markdown="""
## Task Tracker

| Name | Status | Due |
|------|--------|-----|
| Task A | In Progress | Mar 10 |
| Task B | Done | Mar 5 |
| Task C | Blocked | Mar 15 |
"""
)

If you need more control (e.g., inserting a table at a specific position), use NOTION_APPEND_TABLE_BLOCKS directly:

NOTION_APPEND_TABLE_BLOCKS(
  block_id="<page_id>",
  tables=[
    {
      "table_width": 3,
      "has_column_header": true,
      "rows": [
        {"cells": [
          [{"type": "text", "text": {"content": "Name"}}],
          [{"type": "text", "text": {"content": "Status"}}],
          [{"type": "text", "text": {"content": "Due"}}]
        ]},
        {"cells": [
          [{"type": "text", "text": {"content": "Task A"}}],
          [{"type": "text", "text": {"content": "In Progress"}}],
          [{"type": "text", "text": {"content": "Mar 10"}}]
        ]}
      ]
    }
  ]
)

Update Existing Block

To edit an existing block's text content in-place (must have block ID):

NOTION_UPDATE_BLOCK(
  block_id="<block_uuid>",
  content="Updated text content here"
)

Limit: 2000 chars per block. Cannot change block type. Get block IDs via NOTION_FETCH_BLOCK_CONTENTS.

Delete Blocks

To delete (archive) specific blocks:

NOTION_DELETE_BLOCK(block_id="<block_uuid>")

This archives the block (recoverable from Trash). To delete multiple blocks, call this for each block ID. Get IDs first via NOTION_FETCH_BLOCK_CONTENTS.

Override / Replace Page Content

To completely replace a page's content (destructive — confirm with user first):

NOTION_REPLACE_PAGE_CONTENT(
  page_id="<page_uuid>",
  new_content=[...],   # Array of block objects
  backup=true          # Optional: backup current content before replacing
)

This deletes all existing children and inserts new ones. Always confirm with user before using. The backup=true flag creates a recoverable snapshot.

When to Create a New Page

Create a sub-page instead of inserting inline when:

• Content is long (full report, structured document, reference article)
• Content is self-contained and reusable on its own
• User asks to "create a doc", "write a page about", or "document this"
• Inserting inline would clutter the parent page

Workflow:

# 1. Create the sub-page under the parent
NOTION_CREATE_NOTION_PAGE(
  title="Q1 Report",
  parent_id="<parent_page_uuid>"
)

# 2. Add content to the new page
NOTION_INSERT_MARKDOWN(
  parent_block_id="<new_page_id>",
  markdown="## Overview\n..."
)

# 3. Link the new page inside the parent page
# Notion auto-links child pages — confirm by mentioning the link to the user

After creating, always report:

Created: "Q1 Report"
  Parent: Team Workspace > Projects
  Sections: Overview, Results, Next Steps
  Link: [Open in Notion](<url>)

Step 4: Verify and Summarize

Re-fetch the affected portion and summarize:

• what changed
• what stayed the same
• anything that needs user confirmation

Anti-Patterns

• Creating a new page when the user wanted an edit (unless confirmed or content warrants it)
• Overwriting large content without explicit instruction
• Editing without reading current content first
• Dumping raw API output instead of summarizing
• Not providing the link to a newly created page
