Append Markdown Content

notion_append_markdown

Convert and append Markdown content (headings, lists, code blocks, etc.) to a Notion page or block as structured blocks.

Instructions

Append a safe subset of Markdown to a Notion page or block without writing raw Notion block JSON. Supports headings (#, ##, ###), paragraphs, bullet items, numbered items, todos (- [ ] / - [x]), quotes, dividers, and fenced code blocks. Use this when the user provides Markdown-like content and wants it appended; use raw block tools for tables, images, rich text annotations, nested lists, or advanced Notion blocks.

Input Schema

TableJSON Schema
NameRequiredDescriptionDefault
formatNoSpecify the response format. 'json' returns the original data structure, 'markdown' returns a more readable format. Use 'markdown' when the user only needs to read the page and isn't planning to write or modify it. Use 'json' when the user needs to read the page with the intention of writing to or modifying it.
block_idYesThe parent block or page ID to append Markdown content to.It should be a 32-character string (excluding hyphens) formatted as 8-4-4-4-12 with hyphens (-).
markdownYesMarkdown content to convert into simple Notion blocks. Unsupported Markdown is treated as plain paragraph text where possible.
positionNoWhere to insert the content. Omit this to append at the end.
Behavior3/5

Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

Description discloses supported Markdown and fallback to plain text for unsupported elements, but lacks details on side effects (e.g., mutation, idempotency) beyond what annotations (minimal) provide.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness5/5

Is the description appropriately sized, front-loaded, and free of redundancy?

Two concise sentences plus a clear list of supported items, front-loaded with core purpose, no wasted words.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness3/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

No output schema, and description does not mention return value or error handling; while adequate for a simple tool, it leaves some user expectations unaddressed.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters4/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema covers all parameters (100%), and description adds value by explaining markdown parameter behavior (conversion, unsupported fallback) and position omission default, going beyond schema.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose5/5

Does the description clearly state what the tool does and how it differs from similar tools?

The description clearly states the tool appends Markdown to Notion pages/blocks, distinguishes from raw block tools, and specifies supported Markdown subset, making its purpose unambiguous.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines5/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

Explicitly states when to use this tool (Markdown-like content) and when to use alternatives (raw block tools for advanced elements), providing clear guidance.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
