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

Annotations already declare readOnlyHint=true, so the safety profile is covered. The description goes beyond that by disclosing the response contents (pricing, capacity, sales counts broken down by type, questions, activities), which is valuable since no output schema exists. It stops short of error/auth/pagination behavior, so not a 5.

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?

Front-loaded with the action and resource, followed by a compact enumeration of returned data and the endpoint mapping. It is dense but earns most of its words; the endpoint suffix is marginally redundant.

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 read-only tool with no output schema, the description usefully covers the return payload and the parameters are fully documented in the schema. It is nearly complete, missing only failure/empty-slug behavior, which is minor at this complexity.

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 coverage is 100%, so account_slug, event_slug and release_slug are fully documented in the schema itself. The description only reinforces 'by slug' and restates the endpoint path; it adds no meaning or format detail beyond structured fields, 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?

States a specific verb ('Fetch') and resource ('a single release'), and clarifies the domain term by equating a release with a 'ticket type'. The singular framing plus the mapped endpoint distinguishes it from the sibling tito_list_releases without opening a schema.

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 'by slug' and the singular scope versus the sibling list tool, but the description never explicitly states when to prefer this over tito_list_releases or what to do if the slug is unknown. It provides context but no alternatives or exclusions.

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