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

No annotations are present, and the description only states the high-level action. It does not disclose output format, invalid-input behavior, or whether the many extra parameters are ignored or affect the result.

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 main description is a single concise sentence. However, the input schema is bloated with nine irrelevant optional parameters, which undermines the overall structure and focus of the tool definition.

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?

There is no output schema and no description of the return value. For a parsing tool, the expected result shape (e.g., owner and repo as separate fields) is not specified, and failure modes are entirely absent.

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?

Although schema description coverage is 100%, the parameter descriptions are generic and unrelated to parsing GitHub owner/repo (e.g., city, feed, json, zone, query). With nine optional parameters and no meaningful explanations, the schema adds confusion rather than clarity.

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 verb and resource: parse owner and repo from a GitHub URL. It is distinguishable from sibling URL tools like normalize-url or figma-url-shape, though it does not clarify whether it validates the URL or only extracts components.

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?

No guidance is given for when to use this tool over related URL or shape tools. There is no mention of required inputs, expected URL format, or how to handle non-GitHub URLs.

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