Update Link In Bio Socials

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

The annotations already declare destructiveHint=true and idempotentHint=true, and the description usefully explains the destruction mechanism: sending "" or null removes a social entry. It also clarifies that the update is partial, though it does not mention authorization or domain-existence requirements.

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 a single dense but well-structured sentence, front-loading the action and then concisely covering socials, removal semantics, location placement, and partial-update behavior with no filler.

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 destructive mutation with a nested object parameter and no output schema, the description covers the essential update and removal semantics. It leaves minor gaps around error behavior or prerequisite domain existence, but those are partly covered by the schema and annotations.

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 75%, and the description meaningfully supplements it by listing the supported social keys, explaining that values are handles or profile URLs, and defining empty/null removal semantics. The location parameter is also clarified as top or bottom, while domain and dry_run rely on their schema descriptions.

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 uses a specific verb and resource: "Set a Link in Bio page's social icons," and identifies the exact scope (social icons plus location). It is clearly distinct from link/profile/settings updates, though it does not explicitly name those sibling tools as alternatives.

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 phrase "Only the keys sent change" implies partial-update usage, and the removal behavior for empty/null values is useful. However, it gives no explicit when-to-use guidance, prerequisites, or comparison with sibling tools such as update_link_in_bio_profile or update_link_in_bio_appearance.

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