engain_create_comment_task

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

The description discloses credit consumption, which is valuable given no annotations, but it omits critical behavioral traits such as whether the tool is destructive, idempotent, or has rate limits. For a creation tool, more context (e.g., error outcomes, success behavior) is needed.

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 very concise with one sentence and a credit note, but it lacks structure and fails to front-load key details. While every sentence earns its place, the brevity sacrifices important information, making it only adequate.

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 (6 parameters, nested objects) and no output schema, the description is insufficient. It does not mention return values, task creation results, error handling, or any post-comment behavior, leaving the agent with incomplete context.

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?

With 67% schema description coverage, the tool relies on the schema for parameter meaning, but the description itself adds no additional context for any parameters. It does not explain the 'rank' object, labels, or how 'scheduledAt' works, leaving gaps.

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 ('Create') and the resource ('Reddit comment task'), and specifies the scope ('on a thread URL'). It distinguishes from sibling tools like engain_create_post_task and engain_create_reply_task by focusing on comments.

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 does not provide any guidance on when to use this tool versus alternatives. It mentions credit cost but fails to explain scenarios where this tool is preferred over similar ones like engain_create_reply_task or engain_create_thread_task_group.

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