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

With no annotations provided, the description carries the full burden and does meaningful work: it discloses overwrite/versioning semantics ('это новая версия того же сайта') and a pre-publish moderation gate scanning for miners, phishing and redirects — implying the call can be rejected. It still omits auth requirements, limits, and whether prior versions remain retrievable (relevant given vebhost_versions/vebhost_rollback siblings).

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 sentences, front-loaded with the action and its result, then edge-case behavior, then the validation gate. There is no filler and every sentence contributes information an agent would otherwise have to guess.

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 a mutating publish tool with no annotations and no output schema, the description covers what matters most: the returned permanent link, republish semantics, and content screening. It could be tightened further with auth/permission notes, but nothing essential for making a correct call 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 explains html, slug and title. The description only implicitly references the address via 'если адрес уже ваш' and says nothing about the title field or slug format, so it adds little beyond the structured fields. Baseline 3 applies.

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 uses a specific verb and resource ('Опубликовать HTML-страницу') plus a concrete outcome ('вернуть постоянную ссылку'), so the agent knows exactly what is produced. It does not name any sibling (e.g. vebhost_write_file or vebhost_apply), so differentiation from alternatives must be inferred from the verb 'publish'.

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 second sentence clarifies an important usage condition: reusing an address that already belongs to you republishes the same site as a new version rather than creating a duplicate. There is no explicit statement of when to prefer this over writing files or applying changes, and no preconditions (auth, size limits) are stated, so guidance is implied rather than spelled out.

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