add_ticket_comment

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

No annotations are provided, so the description carries the full behavioral burden, yet it discloses nothing beyond the bare action. It does not say whether the comment is attributed to the caller, whether it notifies watchers, whether comments are editable or deletable afterwards, or what the call returns.

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 single short sentence is front-loaded and waste-free, but its brevity reflects under-specification rather than disciplined editing. There is no structure to speak of for a mutating operation.

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 write operation with no annotations and no output schema, the definition leaves critical gaps: success/failure behavior, side effects on ticket state or notifications, and any permission requirements are all unstated. Given the tool's complexity is low, only minimal context is needed, but even that is absent.

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% with both ticket_id and comment documented, so the schema already explains the inputs. The description adds nothing about ID format, comment length limits or accepted content, which is the baseline 3 for fully documented parameters.

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 (add) and resource (comment on a ticket), which is clearly distinct from the sibling create_ticket, update_ticket and get_ticket tools. It stops short of differentiating itself explicitly, but the action 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?

There is no guidance on when to use this instead of update_ticket or create_ticket, no preconditions such as ticket state or required permissions, and no mention of alternatives. The agent must infer the usage context entirely.

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