Update Facebook Page Settings

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

Annotations already indicate mutation (readOnlyHint=false), idempotency, and non-destructiveness. The description adds the permission requirement but doesn't clarify partial-update semantics, rate limits, or failure behavior. It does not contradict annotations.

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?

A succinct mission statement followed by a well-organized parameter list with examples. The description is front-loaded and adds necessary information not present in the schema, with minimal redundancy.

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?

Covers purpose and parameters, and mentions the permission, but misses partial-update behavior, return value, and potential rate limits. For a 10-parameter mutation tool with no output schema, this is a notable gap.

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 detailed semantics for all 10 parameters, compensating for the low 40% schema coverage. It includes clarifications (about vs description), examples for hours and category, and describes nested contact_address.

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?

Clearly states it updates a Facebook Page's profile information, specifying the resource and the action. Lists the fields it covers, distinguishing it from sibling tools like meta_update_page_picture or meta_update_page_cover.

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. It mentions the required permission but does not say when to prefer this over other update tools, nor provides exclusions.

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