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

Annotations already declare readOnlyHint, idempotentHint, destructiveHint=false and openWorldHint=false, so the safety and determinism profile is fully covered without the description. The description adds useful scope context — that the response is static reference material spanning mission, legal status, contact and history — rather than live or query-dependent data.

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 single sentence with a front-loaded subject and a compact enumeration of covered topics; nothing is redundant. The list is slightly laundry-list-like but each item genuinely maps to a distinct section of the returned 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?

With no parameters, no output schema and full annotation coverage, the description's enumeration of content sections effectively doubles as a return-value summary, which is the main thing an agent needs here. Only the routing guidance relative to sibling tools is missing.

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 schema takes zero parameters, so there is no parameter semantics to document; baseline 4 applies. The description correctly adds no param claims, and the empty schema matches the 'no input needed' framing.

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 states clearly that this tool returns background information about The Wiley Rule, enumerating the specific content it covers (mission, the one-line rule, legal status, contact, reporting process, name history). That scope is specific enough to tell it apart from data-oriented siblings like search_products or latest_news, though the verb is implied rather than explicit.

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 explicit when-to-use, when-not, or named alternative is given. The enumerated content topics imply this is the background/context tool to call before using siblings like search_products or who_supports, but the agent has to infer that routing itself.

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