summarize_upgrade

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

There are no annotations, so the description must carry the full burden of behavioral disclosure. It only states 'summarize the changed areas' without explaining what that summary includes, the output format, whether it compares versions from/to, or how the optional parameters like appName and packageName affect behavior. The description is too vague to predict the tool's behavior beyond the basic action.

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, focused sentence that front-loads the verb and clearly names the resource. There is no fluff or repetition, and every word contributes meaning. It is appropriately sized for the information it conveys, though it could be longer to add depth.

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 the lack of annotations, output schema, and minimal parameter descriptions, the one-sentence description is insufficient for a tool with four parameters and two required ones. It doesn't specify what 'changed areas' encompasses, what return format to expect, or how the optional parameters influence the summary. The agent would need additional documentation to invoke the tool with confidence.

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 schema description coverage is only 25% (only 'from' has an example), and the description does not add any parameter-level meaning. It doesn't clarify the relationship between 'from' and 'to', nor the purpose of appName and packageName. With four parameters and a low coverage baseline, the description should compensate but fails to do so.

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 tool summarizes changed areas for a React Native version upgrade, using a specific verb ('summarize') and identifying a distinct resource ('changed areas'). It distinguishes itself from siblings like list_changed_files and get_file_diff by focusing on a high-level summary rather than raw file lists or diffs.

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 implies usage in the context of a React Native upgrade ('for a React Native version upgrade'), which gives a general when. However, it does not explicitly contrast with alternatives like get_upgrade_diff or list_changed_files, nor does it provide any exclusion criteria. The guidance is minimal and implied, not explicit.

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