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

Annotations already declare readOnlyHint=true, idempotentHint=true, and destructiveHint=false, so the safety profile is covered. The description adds useful behavioral context beyond annotations: it promises 'live' data (implying real-time, not cached) and lists exactly what data is returned (tiers, prices, remaining count, purchase link). No contradiction exists between description and annotations.

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, efficient sentence (~25 words) that front-loads the main purpose ('Get live ticket availability') and then lists the concrete outputs. Every word adds value; there is no filler or 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?

Without an output schema, the description fulfills the burden of explaining return values, which it does explicitly: ticket tiers, prices in two currencies, remaining count, and a purchase link. The single parameter is fully documented in the schema, and the tool's simple nature means nothing else is needed to call it correctly.

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?

The only parameter, 'context', is fully described in the schema (100% coverage), leaving no ambiguity. The description does not mention the parameter at all, but per the high coverage baseline, the schema handles the burden. The description adds no extra meaning about the parameter, which is acceptable given the schema's completeness.

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 clearly states the tool's purpose: 'Get live ticket availability and pricing for ELC Conference 2026' and enumerates the specific outputs (tiers, prices, remaining count, purchase link). The verb 'Get' and resource are distinct, and the description differentiates from sibling tools like buy-ticket (which handles purchases) and get-conference-info (general conference details).

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?

While the description does not explicitly name alternatives or exclusions, the phrase 'live ticket availability and pricing' clearly implies an informational check before purchasing, and the sibling list (buy-ticket, get-conference-info) makes the use case inferable. The context is clear, but there is no explicit guidance on when not to use it or alternatives to consider.

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