Get Facebook Page Details

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

Annotations already declare readOnlyHint=true and idempotentHint=true. Description adds that it returns page details including specific fields, which is helpful for understanding output. No mention of permissions or rate limits, but for a read-only tool, the annotations cover safety.

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?

Description is short and front-loaded with the purpose. It includes an 'Args' section and return details. However, the argument listing is redundant with the schema, slightly reducing efficiency. Still concise overall.

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?

With good annotations and full schema coverage, the description covers the essentials. No output schema exists, but description lists key return fields. For a simple retrieval tool, this is sufficient.

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 baseline is 3. The description mentions page_id but does not add meaning beyond the schema. It omits the response_format parameter entirely, but schema already describes it fully. No added value.

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 'Gets detailed information about a specific Facebook Page' with specific verb+resource. Distinguishes from sibling tools like meta_list_pages (which lists pages) and meta_get_page_insights (which returns analytics). The listed return fields (name, category, description, follower counts, linked Instagram account) further clarify scope.

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. Does not mention when not to use, prerequisites (e.g., page access token), or differentiation from similar tools like meta_get_page_insights or meta_get_page_albums.

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