unfollow_user

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

The description offers no behavioral traits beyond the basic action. It does not mention idempotency, error conditions, required authentication, or return value. With no annotations provided, the description carries the full burden and fails to disclose any additional 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 a single, clear sentence with no wasted words. It is appropriately sized for a simple tool.

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 a mutation with no annotations, and the description provides only the core action. It lacks context about when to use it, side effects, or requirements. Although an output schema exists, the description is too thin to be considered complete.

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?

With 0% schema description coverage, the description should compensate by explaining the parameter. It only echoes that the parameter is the user id, providing no additional meaning such as format, validation, or relationship to other resources.

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 clearly states the action ('Unfollow') and the target ('the account with the given user id'), using a specific verb and resource. It is easily distinguished from sibling tools like follow_user, block_user, and mute_user.

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?

No guidance is provided on when to use this tool versus alternatives such as follow_user or block_user. The description only states the action without any contextual usage instructions or exclusions.

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