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

Annotations already cover readOnlyHint, idempotentHint, destructiveHint and openWorldHint, so the bar is lower, yet the description adds real context: Regent performs a policy check and injects the credential, and the key never reaches the agent. 'Nothing is changed and no money moves' reinforces the safety profile in terms the payment-oriented surrounding toolset cares about. It stops short of explaining policy-denial or error behavior.

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 tight sentences, front-loaded with the action and the method constraint before the safety guarantees. Both sentences carry weight, though 'nothing is changed and no money moves' slightly overlaps the destructiveHint/readOnlyHint annotations.

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 gateway/read tool with no output schema, the description covers the target, the method restriction and the credential-handling model, which is what an agent needs to call it safely. It could say more about how the 'path' is composed or what happens when policy denies a request.

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 80% with 5 parameters, so the schema already documents path, facts, intent, method and user_token adequately. The description adds nothing about parameter usage, so the baseline 3 for high coverage is appropriate.

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 (read) and resource (the gigtickets.aqylorda.kz API), plus the allowed HTTP methods, so an agent knows exactly what this does. The name 'gigtickets_read' versus the 'gigtickets' sibling implies a read/write split, but the description never names the write sibling or explicitly says how they differ.

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 parenthetical '(GET, HEAD or OPTIONS only)' implicitly tells the agent this tool cannot perform writes, which is useful routing guidance. However, there is no explicit statement of when to prefer this over 'gigtickets' or the other read siblings, and no prerequisites beyond the implied read-only nature.

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