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

With zero annotations the description carries the full burden, and it does disclose one important trait: filtering is client-side and limited to 'the first pages', so results can be incomplete. However it never says how many pages are fetched, whether results are ordered, or what permissions are needed — significant gaps for an unannotated tool.

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?

One compact sentence with the searchable fields front-loaded and no filler. The parenthetical caveat is worth its space, though it could be sharpened into a concrete depth limit.

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 shape need not be described. But with no annotations and 0% schema coverage, the description should clarify the 'first pages' boundary, pagination behavior, and page_size semantics; as written, an agent cannot predict the completeness of results.

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 coverage is 0%, so the description compensates partially: it explains what 'query' matches (address, project name, order_id) and what 'status' filters on. It says nothing about 'page_size' (default 100) or how query and status combine, leaving a third of the parameters undocumented in both places.

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 (search/filter requests) and enumerates the searchable fields: address, project name, order_id, status. It is distinguishable from siblings like list_klic_requests and get_klic_request, though it never names them explicitly to confirm the distinction.

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?

The parenthetical 'client-side filter over the first pages' implies this is a convenience filter rather than an exhaustive search, which hints at when to prefer list_klic_requests. But no alternative is named and no condition for choosing between them is stated, so usage must be inferred.

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