get_event_activities

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

No annotations are provided, so the description carries the full behavioral burden. Beyond implying it is a read of pre-scheduled activities, it discloses nothing about permissions, pagination, whether past events return empty results, or ordering. The 'Returns' line is redundant because an output schema exists.

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 content is short, but the pipe-separated keyword block and the Args/Returns sections create redundancy with the name, schema, and output schema. It is front-loaded on the core action, which saves it from being wasteful overall.

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?

An output schema exists, so return values need not be described, and the tool takes a single required parameter. What is missing is routing context against the sibling search_event_activities and any read-only/pagination behavior, leaving an agent able to call it but not confidently to choose it.

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 0% and the description's only parameter note is 'event_id: Event ID.', which merely restates the name. It adds no meaning such as where an event ID comes from or whether it must reference an existing event, so it fails to compensate for the empty schema description.

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 ('Get activities scheduled for an event') and reinforces it with searchable synonyms (meeting agenda, event schedule). However, it never distinguishes itself from the very similar sibling search_event_activities, so an agent must infer the difference between a direct lookup and a search.

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?

One sentence gives a usage context ('Use to see what's on the agenda for a committee meeting'), which is a real usage hint rather than nothing. But there are no exclusions and no mention of the close alternative search_event_activities, leaving the agent to guess when a lookup by event_id is preferable to searching.

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