Send DM to Content Commenter

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

No annotations are provided, so the description must fully disclose behavioral traits. It states the tool sends a DM (a write operation) but does not explain effects like whether it creates a new chat, requires specific permissions, or handles errors. Key behaviors are missing.

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 that front-loads the action and key constraints. Every word contributes value; no redundancy or filler.

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 complexity (5 parameters, nested button object, no output schema), the description is too brief. It does not explain the effect of the button payload, response behavior, or prerequisite conditions. An agent may lack sufficient context to use it 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 description coverage is 100%, so the schema already documents parameters. The description adds that text and/or button can be provided, which is a minor clarification. No further insight beyond the schema is given.

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: sending a private message (DM) to the author of a comment. It includes the specific resource (comment author) and contrasts with siblings like repliz_reply_comment (public reply) and repliz_send_message (generic DM). However, it lacks explicit differentiation from all siblings.

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 provides context on when to use the tool (sending DM to comment author) but offers no explicit guidance on when not to use it or which alternatives to consider. Sibling tools such as repliz_send_message and repliz_reply_comment are not referenced.

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