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

With no annotations, the description carries the full burden, and it does disclose two useful traits: the whole operation counts as one version and the risk check runs once for the entire version. It does not state whether deletions are recoverable, whether there is a rollback path, what happens on partial failure, or what permissions are needed.

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 with the core operation front-loaded and no filler. The second and third sentences each contribute a distinct point (typical use case, shared risk check) rather than repeating the first.

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 multi-file mutation tool with no annotations, no output schema, and mostly undocumented parameters, the description covers purpose and atomicity but leaves the operational contract thin. Failure semantics, permission requirements, and the meaning of slug and note are all 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 coverage is only 25%, with just the delete parameter documented, and the description adds nothing about slug, note, files, path, or content. The critical slug identifier and the note field remain unexplained in both places.

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 specific operations and scope: writing multiple files and deleting files or folders as a single version. That distinguishes it implicitly from the single-file siblings vebhost_write_file and vebhost_delete_file, but no sibling is named explicitly, so an agent must infer the boundary.

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 phrase about editing a page and its styles together provides an implied when-to-use scenario: batch edits that should land together. There is no explicit statement of when to prefer the single-file tools instead, nor any prerequisites mentioned.

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