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

With no annotations present, the description carries the full burden and does a reasonable job: it discloses that the response is paginated and that the total count ignores pagination while offset/limit are echoed back. That is real behavioral context beyond the schema. It omits rate limits, auth requirements, and what a 'DSSR location' record actually contains, which keeps it below 5.

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?

Three short, front-loaded sentences with the purpose first, the filter second, and the return shape last. The only waste is the near-duplication of "List DSSR locations" and "Return DSSR locations," which conveys nothing extra.

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?

The description does cover the return shape, which matters since no output schema exists, and the tool has only three optional parameters. But with an adjacent sibling covering the country-scoped variant and no explanation of what DSSR denotes or how this differs, an agent lacks the context needed to choose 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 only 33% — only q is documented ("Search by name"); limit and offset have no schema descriptions at all. The description partially compensates by naming the q=<name> filter and stating that offset and limit are applied, but it never mentions defaults (10/0) or the maximum of 20 for limit, leaving two parameters under-explained.

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 ("List DSSR locations") that is immediately distinguishable from most siblings such as get_allowances or get_fema_hotels. However, it never distinguishes itself from the near-identical sibling get_dssr_locations_by_country, so an agent cannot tell which of the two to pick from the description alone.

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?

"optionally filtered by q=<name>" implies when the filter is useful, but there is no explicit when-to-use statement, no exclusions, and no mention of the by-country alternative that a sibling list makes obvious. Usage is inferable but not guided.

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