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

No annotations are supplied, so the description carries the full behavioral burden, yet it only discloses that entries include path and size. It is silent on whether the listing is recursive, whether it requires an authenticated/owned site, what happens on a bad slug, and whether 'current version' means the published revision — 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 scope ('текущей версии') front-loaded and no filler. It is efficient, though the fragmentary style leaves little room for the missing context.

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 simple one-parameter read tool this is thin: the parameter is undocumented, there is no output schema to explain the returned 'путь и размер', and no indication of how the 'current version' relates to the vebhost_versions sibling. It does at least state the returned fields, which keeps it above a 1.

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 0% and the single required parameter 'slug' is never mentioned. The description only implies that the tool operates on a site, leaving the agent to guess that 'slug' is the site identifier and what format it takes.

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 gives a specific verb and resource ('Список файлов' — file listing) and narrows the scope to 'текущей версии сайта' (current version of the site), which clearly separates it from file-mutating siblings like vebhost_read_file, vebhost_write_file, and vebhost_delete_file. It does not explicitly name any sibling, so it falls short of a 5.

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?

There is no when-to-use guidance, no prerequisites, and no mention of alternatives such as vebhost_versions (to pick a different version) or vebhost_read_file (to see contents). The only hint about usage is implied by the word 'Список'.

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