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

Annotations already declare readOnlyHint, idempotentHint, destructiveHint=false and openWorldHint=false, so the safety profile is covered. The description adds only a vague statement about the config's content and says nothing about scoping to the organization, whether values are masked/secrets, or the return shape, so it contributes little beyond the structured fields.

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?

It is extremely short and there is no padding, but it is a fragment rather than a structured statement, and the brevity comes at the cost of a clear verb and lead-in. Nothing is wasted, but very little is delivered.

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?

With no output schema, the description is the only place an agent could learn what a 'proxy config' returns (URL fields, masking of secrets, empty state). For a read tool with an optional scoping parameter, that gap is not covered anywhere else.

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?

The single optional parameter has 100% schema description coverage ('Approved workspace id only.'), so the baseline is 3. The description adds no extra meaning about what organizationId scopes or what happens when it is omitted.

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 is a bare noun phrase, 'Proxy URLs used for outbound requests', with no verb stating what the tool actually does (retrieve? describe?). It does hint at the content of the config, but an agent must infer the read action from the name and title rather than reading it here, and it never distinguishes itself from sibling set_proxy_config or test_proxy_config.

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 at all and no mention of the obvious alternatives (set_proxy_config to change it, test_proxy_config to validate it). The agent is left to infer usage entirely from the tool name.

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