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

Annotations already indicate this is not read-only (readOnlyHint: false). The description adds the 'requires view access' constraint, which is useful, but it does not describe what the operation returns or any side effects beyond creating a thread. Given annotation coverage of the write nature, 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 sentences, directly stating the purpose and the key parameter behavior. There is no redundancy or irrelevant information; every word adds value.

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?

The description omits essential context for the required parameters (`artifactId` and `body`) and does not mention how the thread is associated with the dashboard. While it covers the element-to-dashboard distinction, it leaves users to infer the meaning of required fields, making it incomplete for a create operation.

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 0%, and the description only explains the `element` parameter. It does not clarify `artifactId` or `body`, which are required. With four parameters and zero schema descriptions, the description fails to compensate for the missing semantics of the required fields.

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 ('Start a comment thread'), the resource ('Pulse dashboard'), and the key behavior of the `element` parameter. It distinguishes this tool from related actions like replying to a comment, making the purpose unambiguous.

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?

It explicitly mentions the view access requirement and explains the conditional use of `element` (pass for element-level, omit for dashboard-level). However, it does not explicitly contrast with alternatives like createPulseDashboardCommentReply, leaving the choice slightly implicit.

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