Create Facebook Page Event

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

Annotations are all false. The description does not add behavioral context beyond the shallow annotation values. It does not mention side effects, permissions, or response behavior, leaving the agent with minimal insight.

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 and starts with the core action. The parameter list is slightly redundant with the schema but adds readability. No wasted sentences.

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?

Despite having 8 parameters and no output schema, the description omits return value, error handling, and necessary permissions. It assumes the agent knows Facebook API context, which is insufficient for a complete decision.

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 provides clear, human-readable explanations for all parameters (page_id, name, start_time, end_time, description, place, ticket_uri), compensating for the schema's low 25% coverage. Each parameter is explained with type and purpose.

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 'Creates an event on a Facebook Page', using a specific verb and resource. This distinguishes it from sibling tools like meta_create_post or meta_create_ad.

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 on when to use this tool versus alternatives. There are many create tools, and the description does not mention when to choose this one over others, nor any prerequisites or limitations.

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