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

Annotations already declare readOnlyHint=true, idempotentHint=true, destructiveHint=false and openWorldHint=false, so the safety profile is fully covered without the description. The description adds only a topical outline of what the response discusses; it does not disclose the return format (e.g., static text vs structured data) despite there being no output schema.

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 that opens with the subject and then lists coverage areas; no filler or repetition. It is list-dense but every clause maps to a distinct topic, so it stays 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?

For a zero-parameter, annotation-covered reference tool with no output schema, the enumerated coverage list largely communicates what the caller will get back. The only shortfall is that it never states the response shape (static documentation text), which an agent would have to discover at call time.

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 no parameters, so there is nothing for the description to disambiguate and the baseline is 4. No parameter-related information is missing.

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 clearly identifies the resource (the DSAR service) and enumerates the topics the tool covers, so an agent knows this is a static service-overview/reference tool rather than an action. It implicitly separates itself from functional siblings such as dsar_deadline or dsar_quote, though it never states the verb ('returns/explains') or names those alternatives directly.

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?

There is no guidance on when to call this versus siblings like dsar_request_scoping, dsar_quote, or dsar_search_checklist, nor any exclusions or preconditions. The agent must infer that this is background material to consult before the more specific DSAR tools.

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