Block/Unblock User from Page

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

Annotations declare idempotentHint=true, which matches the tool's behavior (blocking an already blocked user is a no-op). The description adds the consequence that blocked users cannot post or comment, going beyond annotations to explain the practical effect. No contradiction.

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 concise with a one-line summary followed by a clear bullet-style list of parameters. Every sentence adds value, and the structure is easy to scan.

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 block/unblock tool with 3 parameters and no output schema, the description adequately covers the action and parameters. It could optionally mention permissions or rate limits, but it is sufficient for an agent to select and use the 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?

With 0% schema description coverage, the description fully compensates by listing all three parameters with explanations: page_id, user_id, and unblock (with default and meaning). This adds significant meaning beyond the schema's type definitions.

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 ('Blocks or unblocks') and the resource ('a user from a Facebook Page'), with a specific consequence ('Blocked users cannot post or comment'). It distinguishes from siblings like 'meta_get_blocked_users' by focusing on the mutating action.

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 does not provide explicit guidance on when to use this tool versus alternatives, nor does it mention prerequisites or when to block vs unblock. However, the parameter 'unblock' clarifies the duality, and the context of blocking users is implied.

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