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

Annotations already declare readOnlyHint=true and openWorldHint=false, so the safety profile is covered. The description adds nothing beyond that — no scoping, no mention of which account/platform is queried, no pagination or limit behavior, despite 17 loosely typed optional parameters.

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 single sentence is technically brief, but it is under-specified rather than efficient — the low word count reflects missing information, not tight writing. There is no front-loaded statement of scope or return content.

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 tool with 17 optional parameters, zero required fields, 0% schema coverage, and no description-level parameter guidance, the definition is far too thin. An output schema exists so return values need not be explained, but the invocation contract is left almost entirely unspecified.

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 0% across 17 parameters, and the description mentions none of them. Fields like url, page_id, site_url, client_id, ad_account, ig_user_id, range_preset, and activity_only are entirely unexplained, so an agent cannot know which identifiers are required or how they interact.

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?

"Account overview for insights context" mostly restates the tool name (get_overview) and adds only the vague qualifier "insights context." It does not distinguish this tool from closely named siblings like meta_insights_compare_platforms, meta_insights_get_fatigue, meta_organic_get_overview, or overview_get_account.

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?

There is no guidance on when to use this tool versus the many sibling overview/summary tools (meta_ads_get_summary, overview_get_account, meta_organic_get_overview). No prerequisites, no exclusions, no routing information of any kind.

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