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

With no annotations, the description carries the full burden; it discloses the authorization model (author or owner/admin) and the required context (board_id + task_number), which is genuinely useful. It does not say whether deletion is permanent or reversible, or how failures (missing comment, insufficient permission) surface.

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 tight sentences with the action and the permission constraint front-loaded, followed by the required inputs. Minor filler in 'Use this to', but nothing extraneous.

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 three-parameter delete with a 100%-covered schema, no output schema, and no annotations, the description covers the essentials: what it does, who may do it, and what must be supplied. The main omission is the irreversibility of the operation, which matters for a destructive call.

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%, with each of the three required integers documented in the schema itself ('Board ID where the task belongs.', 'ID of the comment to delete.', 'Task number in board scope.'). The description only restates requiredness of board_id, task_number, and comment_id, adding no format or constraint detail beyond the schema, so the baseline of 3 applies.

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?

States a specific verb and resource: 'delete a comment'. It is clearly distinguishable from the other delete_* siblings (delete_task, delete_status, delete_checklist_item, delete_agent) by resource, though it does not explicitly name or contrast them.

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 supplies the key gating condition (only the comment author or a board owner/admin may delete), which tells the agent whether the caller is even eligible. It does not say when to prefer deletion over an alternative action or mention prerequisites such as the comment needing to exist.

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