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

Annotations already declare readOnlyHint=false, destructiveHint=false, idempotentHint=false, and openWorldHint=false, so safety is largely covered. The description adds a genuinely useful confirmation requirement, but says nothing about the dry-run/confirm semantics, idempotency behavior, or that a ticket ID is returned.

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, front-loaded with the action and ending with the operational constraint; no filler. It is perhaps leaner than ideal for an 8-parameter mutation tool, but nothing is wasted.

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 tool with 5 required parameters and no output schema, the description omits what a successful call returns, how the dry-run/confirm flow behaves, and how idempotencyKey interacts with the idempotentHint=false annotation. Annotations and the 100%-covered schema fill most gaps, so the omission is real but not severe.

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% across all 8 parameters, including the confirm dry-run flag, idempotencyKey, and relatedRecordId, so the schema does the heavy lifting. The description adds no parameter-level meaning beyond it, which is the baseline expectation at full coverage.

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 ("Create a new support ticket"), which is enough for an agent to identify the action. However, it offers no differentiation from nearby siblings such as create_feature_request or reply_to_ticket, which share the support/ticketing domain.

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 only guidance is "ALWAYS ask for confirmation before writing," which is a behavioral rule, not a when-to-use cue. Nothing says when a ticket should be filed versus a feature request, or how this relates to reply_to_ticket for existing tickets.

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