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

readOnlyHint=true already covers the safety profile, but the description adds real value by enumerating the returned fields (price, quantity, tickets_count sold, sold_out/off_sale/secret flags, sale window, share_url) in the absence of an output schema. It does not discuss pagination behavior or rate limits, which keeps it short of 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?

Two tightly packed sentences: the resource and its returned shape first, the underlying API endpoint last. No filler and nothing important buried at the end.

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?

With no output schema, the description's field enumeration is what tells an agent what a release object contains, and pagination/account scoping are handled by the schema. It stops just short of explaining return ordering or pagination limits, so it is complete but not exhaustive.

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 100% and all four parameters (event_slug, account_slug, page, page_size) are documented in the schema itself. The description adds no parameter-level syntax, defaults, or constraints beyond what the schema provides, so the baseline of 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 (List) and resource (releases / ticket types), and explicitly disambiguates Tito's terminology by equating 'releases' with 'ticket types'. The returned field list further pins down what a release record is, distinguishing it from siblings like tito_list_tickets and tito_get_release.

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 description implies the listing context ('List an event's releases'), and the API mapping hints at the scope, but it never states when to prefer this over tito_get_release for a single release or tito_list_tickets. No explicit exclusions or alternatives are named.

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