Getting Deployer installation URL

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

Annotations already indicate readOnlyHint=true and idempotentHint=true, but the description adds the permission requirement 'Perm: manage_endpoints', which provides behavioral context beyond annotations. It also clarifies the non-destructive nature of obtaining a URL.

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 very concise, using only two short sentences to convey the purpose and permission. It front-loads the key action. However, it could be slightly more structured, e.g., integrating the permission note more fluidly.

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?

Given that an output schema exists (not shown but indicated), the description does not need to detail return values. It covers the essential purpose and permission. For a simple URL retrieval tool, this is adequate, though it omits default response format or error scenarios.

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 each parameter already has a description in the schema. The main description does not add additional meaning or usage hints for the parameters, thus it meets the baseline but does not surpass it.

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 'Getting Deployer installation URL' and 'Obtains an URL to download the Deployer installation', providing a specific verb and resource. This distinguishes it from sibling tools like action1_get_deployer, which likely retrieves deployer configuration rather than a download URL.

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 any guidance on when to use this tool versus alternatives such as action1_get_deployer or action1_list_endpoint_deployers. No explicit usage context or exclusions are provided, leaving the agent to infer appropriateness without support.

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