get_upgrade_helper_url

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

With no annotations, the description carries the full transparency burden. 'Build the URL' implies a pure operation, but it does not disclose whether network calls are made, what the output format is, or how invalid versions are handled. The simplicity does not fully compensate for this missing context.

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, front-loaded sentence with no filler. It states the core action and resource efficiently, making it easy to parse at a glance.

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 tool with no output schema and minimal annotations, the description is too sparse. It does not explain return values, parameter roles, or how this URL relates to the upgrade workflow, leaving significant gaps for the agent.

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 only 25% and the description adds no parameter-level detail. It only implies that 'from' and 'to' are versions, while 'appName' and 'packageName' remain unexplained in both schema and description.

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 uses a specific verb ('Build') and resource ('React Native Upgrade Helper URL'), clearly distinguishing this from sibling tools that operate on files/diffs. It communicates exact scope: producing a URL for a version upgrade, which is immediately actionable.

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 alternatives like 'get_upgrade_diff' or 'summarize_upgrade'. No context is provided for prerequisites, typical workflows, or cases where this URL might be needed.

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