B3.3/5.0

Behavior3/5

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

Annotations already declare readOnlyHint, idempotentHint, and destructiveHint, which cover the safety profile. The description does not contradict these annotations and adds that it returns a dictionary, but it provides no additional behavioral details such as error cases, authentication needs, or scope limitations.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness4/5

Is the description appropriately sized, front-loaded, and free of redundancy?

The description is compact and front-loaded with a clear one-line summary. The Args and Returns sections are somewhat redundant with the input and output schemas, but they are standard and do not add meaningful bloat.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness3/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

This is a simple single-parameter read-only tool, and the annotations plus output schema cover a substantial portion of what the agent needs. The main gap is the lack of usage differentiation from get_changeset_history and any notes on edge cases or response semantics.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters4/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema description coverage is 0%, but the description's Args section explains changeset_id as 'The ID of the changeset to retrieve,' which adds operational meaning beyond the schema's type and title. It could be improved with examples or constraints, but it sufficiently clarifies the only parameter.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose4/5

Does the description clearly state what the tool does and how it differs from similar tools?

The description states a specific operation, 'Get information about a changeset,' with a clear resource. However, it does not explicitly differentiate from the sibling get_changeset_history, leaving some potential ambiguity about which changeset-related tool to choose.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines2/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

The description provides no guidance on when to use this tool versus alternatives such as get_changeset_history. There is no mention of prerequisites, context, or exclusions, so the agent must infer usage solely from the name.

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