get_comments_by_author

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

With no annotations, the description carries full burden for behavioral traits. It only states it returns a list of comments, omitting details like pagination, error handling for missing authors, performance implications, or read-only nature. Minimal transparency beyond the basic operation.

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 short and well-structured with Args and Returns sections. Every sentence serves a purpose, but the brevity sacrifices completeness. Front-loaded with the main purpose, which aids quick scanning.

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 existence of an output schema and a single parameter, the description provides the essential information. However, it lacks context about what constitutes an 'author name' (e.g., exact match, partial) and does not mention any ordering or limits. It is adequate but not thorough.

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 0%, meaning the description must compensate. The description merely restates the parameter name ('author: Author name to filter by') without adding format constraints, case sensitivity, or relationship to other parameters. It adds no meaningful value over the schema's type and title.

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 'Get' and the resource 'comments filtered by author name', distinguishing from the sibling 'get_all_comments' by specifying the filter criterion. However, it could be more precise by explicitly contrasting with other comment retrieval tools.

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 provided on when to use this tool versus alternatives like 'get_all_comments' or 'get_comment_count'. The description lacks any contextual cues about prerequisites, limits, or when not to use it.

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