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

Annotations already declare readOnlyHint=true, openWorldHint=true and destructiveHint=false, so the safety profile is covered by structured data. The description adds that the result is a single page rendered as Markdown, which is useful since no output schema exists, but it says nothing about freshness, auth requirements, or pagination (none needed for a single page).

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 front-loaded sentence naming the resource, the return format, and the content scope. No filler, no repetition of the tool name.

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 one-parameter read tool with annotations covering safety and a complete enum in the schema, the description is sufficient: it clarifies the returned format and content. It could go slightly further by noting the page list is enumerated in the parameter, but nothing an agent needs to call it correctly 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?

Schema coverage is 100% and the single 'page' parameter carries a full 14-value enum with its own description, so the schema does the heavy lifting. The description echoes three enum values (risks, fees, agents) without adding syntax or selection guidance beyond the schema; baseline 3 applies.

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?

States a specific resource (one page of Obento's docs) and a specific output format (Markdown), and enumerates the covered topics, so the agent knows exactly what it gets back. No sibling differentiation is stated, but the siblings are unrelated action tools, so confusion risk is low.

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: an agent can infer it should call this to look up how Obento works, fees, risks, security, or the agent guide. There is no explicit when-to-use condition, no statement of when it is unnecessary, and no alternative named.

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