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

Annotations already declare readOnlyHint=true, idempotentHint=true and destructiveHint=false, so the safety profile is partly covered. The description still earns credit for reinforcing that nothing is filed, sent or stored, and for the 'as published' framing, which tells the agent it will get quoted text rather than a paraphrase or an action. It doesn't mention rate limits or failure modes, but those are minor here.

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 safety profile is front-loaded ('Read-only:') and the negative scope appears last, which is the right order. The single long sentence is dense with parentheticals, but each clause carries distinct information about what is returned, so little could be cut without losing payload detail.

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 values need no explanation, yet the description still enumerates the returned contents, which is help for a one-parameter tool. Combined with full schema coverage and annotations covering read-only and idempotency, an agent has everything needed to select and call this tool correctly.

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%, so the single 'language' parameter and its en/es enum are already fully documented, including that it selects which language of the site to quote. The description's 'in English or Spanish' restates the enum rather than adding syntax, default behaviour, or fallback rules. Baseline 3 applies when the schema does the heavy lifting.

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 and resource: it returns the published instructions for reporting a machine or payment problem, and lists exactly what comes back (what to include, email and phone, response and refund lines, report page). The closing sentence 'It does NOT file, send or store a report' separates it from any action-taking tool, and the parenthetical examples of problem types (took money, stopped mid cycle, will not open) make the scope concrete.

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 clear when-to-use context: a machine that took money, stopped mid cycle, or will not open, plus payment problems, and a clear when-not: when the caller wants a report actually filed or stored. It does not name a sibling alternative (e.g. get_contact_form_link) for the case where a contact form rather than reporting instructions is wanted, which keeps it short of a 5.

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