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's one added behavior, that results are capped by limit, merely restates constraints already in the schema (default 50, maximum 100) rather than disclosing anything new about ordering, pagination, or empty results.

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 with the filter set named immediately and the result cap trailing, with no filler. It is efficiently sized, though the parenthetical enumeration reads like a schema echo rather than prose that earns its place.

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 seven optional parameters, no output schema, and only safety annotations, the description is thin: it never explains what a listed requirement contains or how filters interact. It covers enough to attempt a call, but leaves key semantics (include_pattern, missing_pattern_only, enum meanings) unstated.

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 0%, so the description must carry the burden, and it does list five of the seven filters by name, which is better than nothing. However it omits include_pattern entirely and provides no meaning for any filter beyond its name, so an agent cannot tell what min_confidence values imply or what missing_pattern_only changes.

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 clear verb+resource pattern ('List subgoals matching filters') and enumerates the supported filters, so the agent knows it is a filtered listing operation. It does not distinguish itself from near-siblings like list_suites or list_operational_heuristics, and it uses 'subgoals' while the tool name is 'requirements', which adds minor terminology ambiguity.

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 statement of when to use this tool versus alternatives, and no prerequisites or exclusions. The filter list implies a query scenario, but nothing routes the agent away from the many other list/get/search siblings.

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