create_task_comment

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

No annotations are provided, so the description carries the full burden of behavioral disclosure. The description only states the action without explaining side effects, whether it notifies watchers, what happens to notification settings, or what the response looks like. Given the schema includes assignee/notify_all parameters implying notification behavior, this is a significant transparency gap.

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 concise sentence with zero wasted words. It's efficiently front-loaded and easy to scan. It's not verbose, though it's arguably under-specified rather than appropriately concise.

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?

This is a mutation tool with no annotations and no output schema. It has 4 parameters including notification-related ones whose effects are not explained. The description doesn't address notification behavior, return values, or how this differs from the many comment-related siblings. For a tool with side effects, this is incomplete.

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 four parameters (task_id, assignee, notify_all, comment_text) are documented in the schema. The description adds no parameter-level detail beyond what the schema provides. Baseline 3 is appropriate since the schema does the heavy lifting and the description doesn't need to compensate.

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 'Add a comment to a task' uses a clear verb (Add) and resource (comment to a task). It's distinguishable from siblings like create_list_comment and create_chat_view_comment which target different resources. However, it doesn't add specificity about the task context or any nuance beyond the name itself.

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 no explicit when-to-use guidance or alternatives. It implies usage context (adding comments to tasks) but doesn't distinguish from comment-related siblings like create_threaded_comment or create_list_comment. The sibling set indicates when-to-use vs alternatives matters for comment tools, but the description doesn't address this.

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