kitty.ticket.add_comment

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

With no annotations provided, the description must disclose behavioral traits, but it only states the basic action with no mention of side effects, authorization requirements, return values, or consequences. For a mutation tool like add_comment, this is a significant transparency gap.

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 a single, front-loaded sentence with no wasted words. It efficiently conveys the primary action without 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?

Given the lack of output schema and annotations, the description is incomplete for full understanding. It does not explain return behavior, error conditions, or how this comment addition interacts with existing ticket state. The minimal description is barely viable for an agent to invoke correctly without additional assumptions.

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 67% (ticketId and projectSlug have descriptions, but body does not). The description does not add any parameter-level details beyond the schema, leaving the 'body' parameter's semantics implicit. Baseline 3 applies because coverage is high, but the description offers no extra value.

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 'Add a comment to a ticket' is a specific verb+resource statement that clearly distinguishes this tool from siblings like kitty.comments.list (which lists comments) and kitty.ticket.create (which creates a ticket). It accurately and concisely identifies the tool's purpose.

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 provides no guidance on when to use this tool versus alternatives or any exclusions or prerequisites. The agent must infer usage solely from the tool's name and schema, with no explicit contextual cues or contrasting sibling tools mentioned.

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