reply_to_ticket

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

The annotations already indicate a write operation (readOnlyHint=false), and the description correctly implies mutation. No additional behavioral details are disclosed, such as effects on ticket status or notifications.

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?

Single sentence with no extraneous information. Front-loaded with key action and visibility constraint.

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 simple tool with 3 parameters and no output schema, the description adequately conveys the tool's purpose and scope. Could briefly mention the mutation effect, but annotations cover that.

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 covers 100% of parameters with descriptions. The description's mention of 'public' reinforces the default for the 'private' parameter but adds minimal new meaning 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 'Post a public reply visible to the customer' uses a specific verb (reply) and resource (ticket), clearly distinguishing it from sibling tools like 'add_ticket_note' which are private.

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?

Purpose is clear, but the description does not explicitly state when to use this tool versus alternatives. The sibling tools list includes 'add_ticket_note' for private notes, implying usage context, but no direct guidance is provided.

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