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

Annotations already declare destructiveHint=true and idempotentHint=true, so the safety profile is covered. The description adds useful non-schema context — the $0.001 per-call cost and that failed calls are free — but says nothing about whether deletion is permanent, what happens to tickets using the reply, or whether confirmation is required.

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, the action and identifier front-loaded, and the cost note second. No filler.

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 one-parameter mutation with no output schema, the core action and cost are covered, but an agent still lacks the essentials of whether deletion is irreversible and how failures/no-match cases behave beyond 'nothing charged'.

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?

With one parameter and 0% schema description coverage, the description minimally compensates by stating that the reply is identified 'by name' rather than by ID. It does not describe the name format, case sensitivity, whether a full or partial name is expected, or what happens if no match exists.

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 gives a specific verb and resource ('Delete a saved reply') and the title reinforces it. It is clear what the tool does, though it doesn't differentiate itself from similar siblings like ticket_save_template or ticket_list_templates, and it never uses the 'template' terminology the tool name and siblings use.

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 tool versus alternatives (e.g. listing templates first to confirm the name, or saving/editing instead of deleting). The only extra information is pricing, not usage context.

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