summarize_bugfix_contribution

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

No annotations are provided, so the description must disclose behavior on its own. It only states the outcome (summarizing contributors and components) but does not explain how bugfixes are identified (e.g., via keywords), what 'most changed' means, or any side effects or limitations.

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 with no fluff, which is concise. However, it is under-specified and does not follow any structure that separates purpose from usage or parameter notes, making it less effective than a well-organized multi-sentence description.

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?

Given the tool's complexity (7 parameters, output schema, many sibling tools), the description is far too thin. It does not explain required inputs, how to configure the summary, or how it integrates with GitLab data, leaving a significant completeness gap.

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?

The input schema has 7 parameters with zero descriptions, and the tool description does not mention any of them (project, since, until, top_n, branch, bug_keywords, component_path_rules). This leaves the agent with no semantic understanding of what each parameter does, making correct invocation impossible.

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 tool summarizes 'bugfix contributors and most changed components,' which distinguishes it from sibling tools that list or retrieve GitLab entities. However, the verb 'summarize' is somewhat vague and does not explain how the summary is produced.

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 the many sibling tools like list_commits or get_merge_request. The description provides no context on when a summary is needed or what alternatives exist.

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