Reply to a comment thread

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

The description discloses that the action does not resolve the comment, which is key behavioral context. However, with no annotations provided, it could further describe side effects, permissions, or response format. Still, the provided note about non-resolution is valuable.

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 two sentences plus a parenthetical, all front-loaded with essential information. Every sentence adds value without redundancy.

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 simplicity (3 params, no output schema), the description adequately covers invocation context. It could mention that the reply is appended to the thread, but overall it supplies enough for an agent to decide and use correctly.

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%, so baseline is 3. The description adds meaning by specifying the source of 'id' (from check_comments) and the role options (especially for defender). This goes beyond the schema documentation.

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 action 'Add a reply to a comment's thread' and provides specific use cases (ask clarifying question, explain reasoning, push back). It distinguishes from the sibling tool 'resolve_comment', making the purpose unambiguous.

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?

The description gives explicit when-to-use scenarios and explicitly states what this tool does not do ('This does not resolve the comment; use resolve_comment for that.'). It also tells the source of the required 'id' parameter, aiding correct invocation.

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