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

Annotations already declare readOnlyHint=true, so the safety profile is covered. The description adds that the tool builds a map including specific elements, which hints at the output scope but does not describe return format, pagination, or any side effects. Given the annotation coverage, this is acceptable but minimal.

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 bilingual, which adds length but serves a broader audience. The core purpose is front-loaded, and the Args section is clearly separated. No unnecessary filler sentences; each part earns its place.

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?

Given the tool has an output schema (indicated in context), the description doesn't need to explain return values. It covers the main input, how to obtain it, and the tool's purpose. It lacks explicit error handling or limitations, but for a simple read-only map builder 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 coverage is 0%, so the description must compensate. The Args section explicitly states series_id is the series ID and points to get_series_details or search_videos as sources, which is valuable beyond the raw schema. This directly aids correct invocation.

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 tool builds a complete SEO map for a series, listing included elements (seasons, episodes, internal links, schema). While it doesn't explicitly name a sibling tool, the scope is distinct enough from related tools like generate_series_schema or generate_sitemap that an agent can infer its purpose.

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 Arabic section notes the tool is useful for improving internal linking and series discoverability in search results, providing a clear use case. It doesn't explicitly exclude alternatives or name when not to use it, but the context is sufficient for a single-parameter read-only tool.

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