hosting_showJsDeploymentLogs

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

No annotations provided, so the description must disclose behavior. It states it retrieves logs, which implies a safe read operation. However, it does not discuss potential issues like large log sizes, pagination, or error handling for invalid deployment UUIDs.

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 a single sentence that is concise and front-loaded with the primary purpose. Every word serves a function, with no redundancy or extraneous information.

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?

The tool has three parameters and no output schema, yet the description does not explain the return format (e.g., JSON, plain text), pagination behavior, or how to handle errors (e.g., missing deployment). For a debugging tool, this lack of detail leaves the agent underinformed.

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?

All three parameters are described in the input schema (100% coverage). The description adds no additional meaning beyond the schema, such as explaining that 'buildUuid' comes from hosting_listJsDeployments or that 'fromLine' is for pagination. Baseline 3 is appropriate.

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 the verb 'Retrieve logs', the resource 'JavaScript application deployment', and the purpose 'for debugging purposes in case of failure'. It distinguishes from sibling tools like hosting_listJsDeployments (list deployments) and hosting_getNodeJSBuildLogsV1 (Node.js build logs).

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 specifies when to use: 'for debugging purposes in case of failure'. This gives clear context, although it does not explicitly state when not to use or mention alternative tools for other scenarios.

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