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

With annotations already declaring destructiveHint=true, idempotentHint=false, and readOnlyHint=false, the bar is lower. The description adds useful context beyond those hints: removal changes a publicly visible page immediately, which is an important real-world consequence. It does not detail reversibility, permission requirements, or failure behavior, so it is strong but not exhaustive.

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?

Three short sentences, front-loaded with the action and required identifier. Every sentence earns its place: purpose, prerequisite, and important side effect. No redundant restatement of the tool name or annotations.

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?

The tool is simple, has an output schema, and annotations already cover the destructive/idempotent profile. The description adds the key operational context (public visibility, immediate effect, get_mini_site prerequisite). It is nearly complete, though the unexplained siteId parameter leaves a small gap for a multi-parameter tool.

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 must compensate. It explains the required blockId parameter with examples ('a finished tour date or a retired product link') and says how to find the id via get_mini_site. However, the optional siteId parameter is never mentioned or explained, leaving half of the parameter set undocumented.

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 states a specific verb ('Remove'), resource ('one block from a bio page'), and selector ('by its blockId'). It clearly distinguishes the tool from sibling operations like add_mini_site_block, update_mini_site_block, and get_mini_site, so an agent can route correctly without opening schemas.

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?

It gives a concrete prerequisite: 'Call get_mini_site first to find the id.' That tells the agent how to obtain the required blockId. However, it does not explicitly state when to choose this tool over update_mini_site_block or delete_draft, nor does it name exclusions, so it falls short of a full when/when-not routing guide.

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