list_events

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

Description repeats the name's implication without adding behavioral context beyond annotations. Annotations already declare readOnlyHint=true and openWorldHint=true, so the description adds no new information about side effects or scope.

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?

Single sentence, front-loaded, no extraneous words. Every character is purposeful.

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?

Given no parameters, no output schema, and annotations, the description is adequate but minimal. It fails to mention output format, pagination, or any constraints like date ranges, which would be helpful for a list tool.

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?

No parameters exist, and schema coverage is 100% (empty properties). With zero parameters, the baseline is 4; no further explanation is needed.

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?

Description clearly states 'List all fundraising events' with a specific verb and resource, distinguishing it from 'get_event' which retrieves a single event. However, it does not explicitly differentiate from other list tools like 'list_event_invitations'.

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?

No guidance provided on when to use this tool versus alternatives such as 'get_event' or 'list_event_invitations'. The context must be inferred from the tool name alone.

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