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

No annotations are provided, so the description carries the full burden of behavioral disclosure. It does not state whether the operation is read-only, what the response contains (e.g., diffs, changed files), or any prerequisites or side effects. This is a critical gap for a comparison tool.

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, which is concise, but it is under-specified. It lacks critical information, making it more of a placeholder than a helpful guide. Front-loading fails because there is almost no content.

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?

With 7 parameters, including nuanced logic for sourceType/targetType and straight, and no output schema or annotations, the description is inadequate. It doesn't explain the comparison semantics, expected output, or edge cases like branch/tag name conflicts, leaving the agent without enough context to use the tool safely.

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 coverage is 100% and the schema already provides detailed descriptions for each parameter (e.g., straight, sourceType, targetType). The description adds no parameter-specific information, but the baseline is set at 3 given the comprehensive 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 'Query code to compare content' is vague; it doesn't specify what is being compared (commits, branches, tags) or the output format. It fails to distinguish itself from sibling tools like get_commit or list_commits, which also deal with code content.

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?

There is no guidance on when to use this tool versus alternatives. It does not mention scenarios where comparing references is appropriate or when to use other commit/branch tools instead.

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