Get an Etix venue and its upcoming events by id

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

Annotations already cover readOnlyHint and idempotentHint, so the safety profile is established. The description adds useful context beyond those flags: no Etix account required, the expected response contents, and that only upcoming events are returned. It does not mention rate limits or freshness, but openWorldHint and the simple read-only nature make those less critical.

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 tight sentences: the first establishes the operation and output, the second gives the source and follow-up workflow, and the third states auth and safety. Every sentence adds value and the most important information is front-loaded.

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 one required parameter, no output schema, annotations covering read-only/idempotent behavior, and a description that specifies the return payload and workflow, the definition fully equips an agent to call this tool correctly. No critical information is missing.

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%, so the schema already documents venue_id, its integer type, range, example, and source (etix_search). The description reinforces 'numeric' and the source, but adds no meaningful parameter meaning beyond what the schema already provides.

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 opens with a specific verb and resource: 'Fetch a single Etix venue by its numeric venue_id.' It enumerates the returned data (name, organizer, address, upcoming events with event_id, name, start time, ticket URL) and explicitly distinguishes its role from etix_search and etix_get_event.

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 gives an explicit workflow: obtain venue_id from etix_search, use this tool to fetch the venue and its events, then follow up with etix_get_event for any listed event. This clearly communicates when to use this tool and how it relates to its siblings.

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