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

Annotations already declare readOnlyHint, idempotentHint, closed-world and non-destructive behavior, so the description is not obliged to restate safety. It adds useful separation of concerns: search returns results whose text/link/case numbers come from `document`, and it clarifies that court_body=vs is a legitimate cross-cutting digest covering about a quarter of the corpus rather than a null. It does not describe result shape, ranking or pagination behavior for the search itself.

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?

Front-loaded with what the corpus is, then the ЄДРСР boundary, then two targeted clarifications. No filler sentences. The mix of Cyrillic source vocabulary with English prose is dense but each phrase carries meaning; a reader unfamiliar with the Ukrainian terms may need a beat, but nothing is wasted.

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 an 8-parameter, no-output-schema search tool, the description covers identity, scope and one tricky enum value, but says nothing about what a search result looks like (only what the `document` sibling returns) or how limit/offset paging interacts with total results. Adequate to call the tool, incomplete for predicting the response.

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 75%, so much of the parameter meaning is already structured. The description nonetheless adds a valuable, non-obvious clarification for court_body='vs' (cross-cutting digest, not a missing value) — exactly the kind of trap an agent would otherwise misinterpret. It adds nothing for limit/offset/year range beyond the schema.

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 names the resource precisely: the Supreme Court's analytical publications (дайджести, огляди, узагальнення судової практики, наукові висновки НКР при ВС). It also states the boundary against ЄДРСР ('has the judgments but no positions by dispute category'), so an agent can distinguish this from ua_edrsr__search. It never says 'search', but the scoping is specific enough to be actionable.

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?

It gives an implicit when-to-use rule by contrasting with ЄДРСР (positions by dispute category vs. raw judgments) and routes to the sibling `document` tool for full text, link and case numbers. There are no explicit when-not-to-use conditions beyond that contrast, but the alternative-routing is clear.

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