notion_update_block

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

Annotations already declare readOnlyHint=false, idempotentHint=true, and destructiveHint=true, so the description need not restate those. It adds useful behavioral context beyond annotations: the tool is confined to a governed connector authority, the `effect` is a claimed read/write flag verified by Spring, and writes may require an `approval_ref` to resume. This gives an agent meaningful expectations about auth and approval flow, though it stops short of describing the exact update behavior.

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

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

The description is well-organized and front-loaded: the operation identity and routing constraint come first, followed by a clean bulleted argument list. No sentence is filler. It could be improved by replacing the tautological opening with a plain-language statement of what the operation does, but as written it is efficient and scannable.

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

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

Despite the detailed parameter annotations, the description is incomplete for an agent trying to use this tool correctly. It does not explain what updating a Notion block involves, what keys should go inside the `arguments` JSON, or when this wrapper is preferable to sibling Notion tools. The output schema may cover return values, but the missing domain semantics and selection guidance leave a significant gap.

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

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

Schema description coverage is 0%, so the description carries the full burden for parameter meaning. It provides concise semantics for all seven parameters, including the JSON-string nature of `arguments`, identity fields, idempotency, effect verification, and approval reference. The main weakness is that the inner content of `arguments`—the actual Notion update_block payload—remains unspecified, which limits the agent's ability to construct a valid call.

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

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

The description identifies the operation as a Notion connector operation named `update_block` and gives the platform alias `notion.update_block`, so an agent can infer the basic verb+resource from the name. However, it never states what updating a Notion block actually does (e.g., modifies block content or properties), and it does not distinguish this tool from siblings like notion_update_page, notion_delete_block, or notion_bulk_update_pages.

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

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

There is no guidance on when to use this tool versus alternatives. The only contextual statement is that it 'routes only through the exact project/account governed connector authority,' which is a routing constraint rather than usage direction. No exclusions, alternatives, or prerequisites are mentioned.

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