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

Annotations already declare readOnlyHint=true and destructiveHint=false, so the safety profile is covered. The description adds real value beyond them by disclosing the auth requirement ('Needs the user's Cotlet API key with access to this app') and clarifying what the response contains.

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 opening sentence is a fragmented label ('Tiqets: Product page: ...') that is then partly restated by 'Returns the details Tiqets shows on the product page,' creating redundancy. The cancellation-terms and API-key sentences do earn their place, so it is adequate but not tight.

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 single-parameter read tool with no output schema, the description adequately summarizes the return payload and the auth prerequisite. Coverage is good, though it could have said more about the exact shape of the returned detail (e.g., availability or pricing).

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?

There is a single parameter with 100% schema description coverage, and the schema already explains that product_id comes from search_experiences. The description adds no syntax or format detail beyond the schema, so the 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?

The description names a specific verb+resource (get an experience's product-page details) and enumerates what is returned: inclusions, meeting point, instructions and cancellation terms. The schema's product_id references search_experiences, so an agent can place it in the search-then-fetch flow, though sibling tools like get_booking are not explicitly contrasted.

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?

'Cancellation terms tell your agent whether free cancellation is on offer before you book' implies the pre-booking use case, which is useful context. However, there is no explicit statement of when to prefer this over siblings (e.g., get_booking, check_availability) or any exclusion condition.

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