get-changelog

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

With no annotations, the description carries the burden and clearly states the tool is a read-only retrieval of the changelog ('获取'). It does not mention output format or source, but for a zero-parameter read tool there is little additional behavioral risk to disclose.

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?

Two sentences with numbered use cases, front-loaded with the verb and resource. The two use cases somewhat overlap, which prevents a 5.

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 parameterless read-only changelog tool with no annotations and no output schema, the description tells the agent what the tool returns and when to use it. Nothing necessary for correct invocation is missing.

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?

There are zero parameters, so the baseline is 4; the description correctly focuses on purpose rather than parameter details.

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?

Description states "获取 Mybatis-Flex（mybatis-flex）的更新日志 Changelog" — a specific verb and resource. It is clearly distinct from siblings list-api, get-api-doc, and get-mybaitis-flex-info because it targets the project changelog rather than API listings or general framework info.

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?

Provides explicit use cases: wanting to review framework update history or learn about newly added features. It does not explicitly exclude any sibling, but the scenarios are specific enough that no agent would confuse it with the sibling tools.

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