Adds a new proxy entry using the provided configuration parameters.

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

Annotations already disclose the mutation profile (readOnlyHint=false, destructiveHint=false, idempotentHint=false), so the safety burden is largely covered. The description does add one piece of behavioral value that no structured field supplies: it returns the generated unique identifier, which matters since there is no output schema. It says nothing about whether duplicate names are allowed or what happens on invalid proxyUri.

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, but the first opens with the filler phrase 'This method is used to' and pushes the actual verb back, and it largely repeats the title. The second sentence (return value) earns its place; the first is padding.

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 five-parameter mutation tool the description covers the essentials only because the schema is fully annotated and annotations declare the safety profile. The genuinely useful addition is the return-value note, but required-parameter reality (name cannot be null or empty while the schema lists zero required fields) and failure behavior are left unaddressed.

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 all five parameters (name, folderId, proxyUri, ipChangeUrl, workspaceId) are already documented with defaults and constraints in the schema. The description adds no syntax, format, or inter-parameter semantics beyond that, so the 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 states a specific verb (add) and resource (a new proxy entry), so an agent can tell what the tool produces. However, it offers no differentiation from close siblings such as bulk_create_proxy (multi-create) or update_proxy (modification), leaving the agent to infer the boundary from the names alone.

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 guidance on when to use this tool versus bulk_create_proxy, update_proxy, or the folder-creation siblings, and no prerequisites or preconditions are mentioned. The sentence 'using the provided configuration parameters' restates the schema rather than saying anything about when this call is appropriate.

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