set_multihop

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

With no annotations, the description carries full burden. It explains the behavioral change (adding an extra privacy layer) and states the return value, but omits details like immediate effect, impact on existing connections, or authorization needs.

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?

The description is concise with two paragraphs and an Args/Returns section. No redundant information, though the Args section partially duplicates schema structure.

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?

Missing pointers to sibling tools that list valid country/city codes. Also fails to clarify that entry_country and entry_city are only relevant when enabled is true. The return value description is somewhat vague ('current relay constraints').

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 0%, so description must compensate. It lists parameter purposes (enabled, entry_country, entry_city) but lacks validation hints or references to sibling tools (list_cities, list_countries) that provide valid values.

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 clearly states 'Enable or disable multihop (chained VPN connections)' and explains what multihop does, distinguishing it from sibling tools like set_location or set_protocol.

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 description lacks guidance on when to use this tool over alternatives. No explicit conditions, prerequisites, or context for choosing multihop among many similar settings.

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