notion_delete_block

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

With no annotations, the description fully discloses the destructive nature, recovery window (30 days), and the cascading effect on child blocks. This provides thorough behavioral transparency beyond what annotations would typically offer.

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 extremely concise, with two sentences that each carry essential information. Warning and action are front-loaded, and no extraneous text is present.

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?

For a simple tool with one parameter and no output schema, the description is fully complete. It covers the action, prerequisites, consequences, and edge cases (parent deletion).

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?

The schema has 100% coverage with a clear description for the only parameter. The description adds value by contextualizing the block_id as something to be obtained via notion_get_blocks, enhancing the parameter's meaning.

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 explicitly states 'deletes a single block' and distinguishes the tool from siblings like notion_delete_page (deletes a page) and notion_get_blocks (used to find the block ID). The action and resource are clear and specific.

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?

The description instructs to use notion_get_blocks to find the block ID first, providing clear guidance on prerequisite steps. It also warns about cascading deletion when deleting parent blocks. However, it does not explicitly state when not to use the tool.

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