engain_create_reply_task

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

No annotations are provided, so the description must disclose behavioral traits. It mentions credit cost ('SPENDS CREDITS (typically 5)') but fails to disclose other important traits such as authentication requirements, rate limits, error handling, or whether the operation is reversible.

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 extremely concise with two sentences. The first sentence states the core purpose, and the second adds the critical credit cost. No superfluous information, and the most important details are front-loaded.

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?

Despite having 6 parameters, a complex nested object (rank), and no output schema, the description is too sparse. It does not explain how to use the rank plan, the expected format of content, the role of labels, or what the response contains. The tool's complexity is not matched.

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 50% (only url, rank, projectId have descriptions). The description adds no additional meaning beyond the schema; it does not explain the rank object, content meaning, or scheduledAt behavior. Key parameters like content and labels lack any explanation.

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 'Create a Reddit reply task to a specific comment URL', specifying the verb, resource, and target. It distinguishes from sibling tools like create_comment_task and create_post_task, which target different resources.

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 no guidance on when to use this tool versus alternatives. It does not mention conditions, prerequisites, or compare with sibling tools like engain_create_comment_task or engain_create_post_task.

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