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

Annotations already cover the safety profile (readOnlyHint=true, openWorldHint=false), so the bar is lower. The description adds real value beyond them by disclosing the response shape (slug, price anchor, page URL) and the intended follow-up chain, though it says nothing about auth, rate limits or empty-result behavior.

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?

Two tight sentences: the corpus and domain list come first, then the trigger, then the return shape and next-step routing. No clause is redundant with the schema or annotations.

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 no output schema, the description usefully names the returned fields and the downstream tools, which is what an agent needs to chain calls. It omits any note on pagination/limit interaction or empty results, but nothing critical for correct invocation is missing.

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 100%, so the schema already documents query, limit and locale with examples and constraints. The description adds no syntax or default detail beyond that, so the baseline 3 applies; the 'pass a slug' note refers to an output field, not an input parameter.

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 the Pactum catalog of legal services in Uzbekistan) plus the covered domains, so the agent knows exactly what corpus is being queried. It also contrasts implicitly with search_articles and list_practice_areas by scoping to bookable services.

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?

Gives a clear trigger condition ('Use when the user describes a task they want done') and routes the agent onward to get_service or request_quote once a slug is in hand. It stops short of naming when NOT to use it versus search_articles, so it is strong but not fully exhaustive.

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