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

Annotations already declare readOnlyHint, idempotentHint and non-destructive behavior, so the safety profile is covered. The description adds that the content is 'current/up-to-date' and includes metadata plus a citation URL, which is useful but not rich behavioral context (no pagination, no error behavior for bad slugs).

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 short sentences, front-loaded with the returned value and followed by the accepted input form. No filler, no repetition.

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?

No output schema exists, so the description carries the return-value burden and does so: Markdown body plus metadata and a citation URL. It is nearly complete for a single-resource reader; only missing guidance about invalid/missing slugs or how format=text differs.

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 50%: 'slug' is documented with an example, but 'format' has no description at all. The description compensates partly by clarifying that the input accepts either a slug or a full page URL, adding meaning beyond the schema; the format parameter's markdown/text distinction is left entirely to the enum.

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: returns the current full content of a KZSalesHub article ('Актуальное содержимое материала') in Markdown with metadata and a citation URL. This clearly distinguishes a full-document fetch from the search_* siblings, though it never names those alternatives explicitly.

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 when-to-use or when-not-to-use guidance. It does not tell the agent to prefer this over search_knowledge/search_cases when it already has a slug, nor does it explain what to do when only a query is available. Usage is only inferable from the name.

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