Get React Native Upgrade Information

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

With no annotations provided, the description carries the burden of disclosing behavioral traits. 'Extract' implies a read-only operation, but the description does not explicitly state side effects, required permissions, rate limits, or what the output represents. The agent is left guessing about the tool's behavior.

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 with no fluff, making it concise and easy to parse. It front-loads the primary action and resource. However, it is perhaps too terse given the tool's complexity, though this does not hurt conciseness itself.

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 description is not complete for a tool with 4 parameters, no annotations, and no output schema. It fails to explain what 'upgrade information' entails, what the return format is, or any prerequisites. An agent cannot fully understand the tool's behavior or expected results from the description alone.

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 all parameters are already documented in the input schema. The description adds minimal semantic value beyond restating 'between two versions' which corresponds to the fromVersion and toVersion parameters. The optional parameters packageName and projectName are not mentioned in the description but are fully covered in the schema.

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 ('Extract') and names the resource ('React Native upgrade information') with the scoping 'between two versions'. It is clear about the core function, though it does not explicitly differentiate from the sibling get_file_diff, which likely serves a different purpose.

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 gives no guidance on when to use this tool versus alternatives, no prerequisites, and no context about when it is appropriate to invoke. There is no mention of when not to use it or how it relates to get_file_diff.

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