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

Annotations already declare readOnly/idempotent/non-destructive/closed-world, so the safety profile is free. The description adds real value beyond that: the text is Persian fa-IR RTL, drawn from public fekrestan.com pages, and explicitly excludes in-app exercise answers — a content boundary an agent would not otherwise know. It does not mention list size or pagination.

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?

Three short sentences, front-loaded with what the pages are, then the return fields, then the language/audience, then the exclusion. No sentence is redundant.

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 zero-parameter read-only list with no output schema, the description supplies the resource, the per-item fields, the language/locale, and the scope exclusion — enough to call it correctly. Only list cardinality/pagination behavior is left unstated.

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 tool takes zero parameters, so there is nothing for the description to disambiguate; baseline 4 applies. The description does voluntarily describe the shape of each returned record, which compensates for the absence of an output schema.

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?

Names a specific resource (the published «روش حل» pages, one per question type) and enumerates the returned fields (slug, title, short answer, URL). It implicitly contrasts with the singular get_how_to_solve by emphasizing 'published pages' as a collection, but never states that contrast outright.

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?

Usage is only implied: the 'for parents and teachers' audience plus 'No answers to in-app exercises' scopes the content. There is no explicit 'use this to browse all methods, use get_how_to_solve to fetch one page' routing, and no prerequisites are stated.

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