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

Annotations only supply destructiveHint=true; the description adds the required OAuth scope (flex.collaboration.ticketComments.create), the write nature of the call, and the member/public-attribution constraint. It does not describe the response payload or whether comments can be modified afterward, but the added operational context is substantive and consistent with the annotation.

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?

Three short sentences, front-loaded with the WRITE marker and the core action, with no filler. The trailing 'OfficeRnD: POST /ticket-comments/{ticketId}' endpoint notation is low-value implementation detail, but the body is otherwise tight.

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?

With four required parameters, no output schema, and only a destructiveHint annotation, the description covers the essentials: auth scope, write semantics, visibility rules, and the attribution constraint. It leaves unclear what the call returns and whether the posted comment is mutable, a minor gap for a straightforward 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 coverage is 100%, so the baseline is 3; the description earns an extra point by stating the cross-parameter constraint that a comment attributed to a member must be public, which is not expressed anywhere in the schema. It does not extend the meaning of text or ticket_id beyond the schema.

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?

Opens with a specific verb+resource pair ('Post a comment on a helpdesk ticket') and a WRITE marker, which cleanly separates it from siblings like officernd_create_ticket and officernd_list_tickets. An agent can identify the action without opening the schema.

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?

Provides a real conditional rule ('comments attributed to members must be public') and the visibility meaning of public comments, which shapes invocation. However, it never states when to choose this tool over alternatives or when not to use it, so guidance is implied rather than explicit.

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