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

Annotations already declare destructiveHint=true and idempotentHint=false, so the safety profile is covered; the description adds real value beyond them by spelling out the authorization rule (author or board admin). It stops short of saying whether the deletion is permanent or what error results from an unauthorized or repeat call.

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?

Two short sentences with the action front-loaded and no filler. The opening clause slightly echoes the tool name/title, which is the only redundancy.

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?

For a destructive three-parameter tool with full schema coverage and annotation-declared safety hints, the description covers action, authorization, and required inputs. It omits irreversibility and post-delete response behavior, which would be the last piece for a 5.

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 three parameters are already documented, and the baseline is 3. The description only restates the parameter names ('Provide board_id + task_number for context and comment_id') without adding format or scoping detail 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?

The description states a specific verb and resource ('delete a comment'), which cleanly separates it from add_comment, list_comments, and update_task-style siblings. It does not explicitly name an alternative, but the operation itself is 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 gives a concrete applicability condition that an agent must check before calling: only the comment author or a board admin/owner may delete. It doesn't state when-not-to-use or point at alternatives (e.g., leaving a comment instead of deleting), so it falls short of a full 5.

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