unblock_user

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

With no annotations provided, the description carries the full burden. It discloses the risk of rate-limiting and temporary restriction, which is helpful. However, it does not mention other aspects like permission requirements, idempotency, or what happens if the user is not blocked.

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 very concise: two sentences and a bullet point. The first sentence states the purpose, and the note is clearly separated. No unnecessary words.

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 unblock action, the description covers the core purpose, parameter usage, and an important warning. Although it could mention error handling or prerequisites, the presence of an output schema (unknown content) may compensate. Overall fairly 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?

The description adds value to the input schema by explaining that screen_name should be a 'Twitter username (without @)'. This clarifies the format, which is not present in the schema (0% coverage).

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 tool 'Unblock a user by screen name', which is a specific verb and resource. It distinguishes itself from sibling tools like block_user and mute_user by the action unblock.

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 provides a warning about rate-limits and bulk usage, but does not explicitly state when to use this tool versus alternatives like unmute_user or block_user. It implicitly defines usage as unblocking, but lacks comparative guidance.

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