comments_replies_create

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

No annotations are provided, so the description carries the full burden. It discloses the core behavior (creating a reply) and mentions notification settings, but it does not explain any side effects, permission requirements, or what happens with notify_all (e.g., default behavior). This is adequate but not rich.

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 concise sentences with no redundancy. It front-loads the core purpose and includes the extra feature (notification settings) in a compact manner.

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?

For a simple create tool without output schema or annotations, the description covers the core purpose and a key feature. It lacks details about response format or error conditions, but the tool is simple enough that this is not a major gap. It is nearly complete for its complexity.

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 description coverage is 100%, so all three parameters (comment_id, comment_text, notify_all) are documented in the schema. The description adds minimal additional meaning beyond noting notification settings, which aligns with the notify_all parameter. Baseline 3 is appropriate.

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 states a specific action (create) and resource (a threaded reply to a parent comment), clearly distinguishing it from sibling tools that create top-level comments or list replies. It precisely identifies the tool's function.

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 implies this tool is for replying to an existing comment rather than creating standalone comments. It does not explicitly name alternatives, but the phrase 'to a parent comment' provides clear context for when to use it. Lacks explicit when-not-to-use guidance.

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