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

Annotations already declare readOnlyHint=true, destructiveHint=false and openWorldHint=false, so the safety profile is covered. The description adds that the whole body text is returned and that the scope is this one site, but says nothing about truncation limits, size, or what happens on a missing/invalid id.

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?

Two sentences, no filler, and the accuracy instruction lands at the end as a clear call to action. The site name is front-loaded in a slightly awkward way, but overall the text is tight and readable.

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?

An output schema exists, so return-value shape need not be explained, and the description correctly focuses on input sourcing and when to trust fetched content. For a single-parameter read tool this is close to complete; only edge-case behavior (invalid id, oversized page) is unaddressed.

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 100% and the single `id` parameter is already documented as accepting a search-result id, a URL, or a path, including Japanese characters. The description largely restates that same information, adding no new syntax or format guidance.

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 verb+resource: returns the full body text of a loaded page on the target site (fugusugata.jp). It is clear what comes back, but it never distinguishes itself from the sibling get_page, which by name appears to do something very similar, so the agent must guess between the two.

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?

Gives a concrete usage trigger: verify the body text before answering anything where accuracy matters (prices, dates, conditions, terms). It also hints at the workflow by saying the id can come from search results. No explicit alternatives or exclusions are named, though.

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