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

Annotations already declare readOnlyHint=true and destructiveHint=false, and the description adds real context: links come in whatever format Tiqets provides for that product, they are for the caller's eyes only ('do not share them'), and an app-scoped API key is required. It omits rate-limit or expiry behavior for the links.

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?

Three short sentences, front-loaded with the core purpose before the sharing and auth caveats. Every sentence carries information, though it could be slightly tighter.

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?

No output schema exists, so the description appropriately explains the return (links to ticket files) and adds an auth prerequisite. Combined with annotation coverage of the safety profile, this is complete enough for a single-parameter read tool.

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?

Only one parameter with 100% schema coverage, whose schema text ('Order ID from list_bookings') is already self-documenting. The description adds no format or sourcing detail beyond the schema, so baseline 3 applies.

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 ('Download links for the e-tickets of one booking') and clarifies it returns ticket-file links. An agent can tell what it does, though it does not name a sibling to differentiate against the way a 5 would.

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?

Usage is implied by 'of one booking' and a prerequisite is stated ('Needs the user's Cotlet API key with access to this app'), but there is no explicit when-to-use guidance relative to siblings like tiqets_get_booking or tiqets_list_bookings.

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