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

Annotations already declare destructiveHint=true, idempotentHint=true, and openWorldHint=true, so the safety profile is covered. The description still adds value by stating the removal is 'Permanently' and that it 'Returns the resulting page preview', and it flags the authenticated-creator scope.

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?

Two tight sentences with the destructive action front-loaded and the return behavior second; nothing is wasted.

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?

With full schema coverage, complete annotations, and an output schema present, the description need not explain return values, yet it still notes the preview return and auth scope. It is complete enough for a one-parameter destructive 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 coverage is 100% and the single block_id parameter is fully documented in the schema (pattern plus 'Block ID from link_in_bio_get'). The description adds no parameter detail, so the baseline 3 is appropriate.

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 pairs a specific verb ('remove') with the exact resource ('one selected block from the authenticated creator page'), making it immediately distinguishable from siblings like link_in_bio_upsert_block and link_in_bio_update.

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 implies the operation's context ('one selected block') but never states when to use this versus link_in_bio_update or link_in_bio_upsert_block, nor any prerequisites or exclusions. Usage is inferable but not made explicit.

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