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

Annotations already declare readOnlyHint, idempotentHint, openWorldHint, and destructiveHint=false, so the description does not need to restate safety. It adds a scoping detail ('recent') and the breaking-changes filter, but does not disclose return format, pagination, or ordering. With strong annotation coverage, this is acceptable but not rich.

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 short sentence that front-loads the core operation. Every word earns its place and there is no boilerplate or repetition.

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 simple read-only tool with zero required parameters and fully documented optional parameters, the description provides enough to invoke it correctly. It lacks an explicit return-shape description, but no output schema exists to fill that gap; this is a minor omission for a straightforward changelog getter.

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 the schema already explains projectId and breakingOnly fully. The description adds no additional parameter meaning, which is fine because the schema bears the load.

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 identifies a specific verb ('Get') and a specific resource ('recent API changes and breaking changes'), making the tool's role as a changelog reader clear. This distinguishes it from siblings like search_docs, get_endpoint, and list_sdks without needing to open the schema.

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 phrase 'recent API changes' implies the tool should be used when the agent needs the latest changelog, and the breaking-only filter hints at a filtering use case. However, it does not explicitly state when to prefer this over siblings such as search_docs or get_guide, nor does it mention exclusions.

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