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

Annotations set idempotentHint=true, which matches the tool's nature. The description adds the prerequisite but does not disclose additional behavioral traits beyond what annotations already provide. For a non-destructive, read-only-like operation, this is adequate but not exceptional.

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 no wasted words. It uses a clear bullet list for arguments and front-loads the purpose. Every sentence serves a purpose.

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 set operation, the description provides the prerequisite and parameter details. However, it does not explain the response_format parameter or what the output looks like, which could be useful given no output schema. It is mostly complete but missing response information.

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 description coverage is 100%, so the schema already documents all parameters. The description lists args with brief explanations, but these largely mirror the schema descriptions. No additional semantic value is added beyond the schema.

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 verb 'Sets' and the resource 'instant reply message for a Facebook Page'. It distinguishes from sibling tools like meta_set_away_message and meta_set_greeting by specifying the exact function.

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 explicitly states a prerequisite: 'Requires: meta_list_pages called first to load page tokens.' This provides clear usage context. However, it does not mention alternatives or when not to use this tool.

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