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. It usefully discloses the return shape ('data.events and top-level page'), empty-result semantics ('empty events means no matches'), and cursor stability rules for later pages. However, it does not state read-only intent explicitly, auth requirements, rate limits, or error behavior, so meaningful gaps remain.

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 description is compact and front-loaded: purpose first, then return values, then pagination instructions. Every sentence contributes, though 'other financial events' is vague enough to slightly weaken the opening.

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 seven parameters, no annotations, and no output schema, the description does well to explain return shape and pagination. It still leaves out required-category orientation and sibling differentiation, which are important for correct invocation. The schema covers parameter details, but the description is not complete enough to guide selection confidently.

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 all seven parameters, including the required category enum and cursor/date defaults. The description adds only high-level filter mention ('date/symbol/market filters') and repeats cursor pagination behavior already present in the schema, so the baseline of 3 is appropriate.

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 names a specific verb and resource ('Get other financial events') and mentions filters and pagination. However, 'other' is vague and does not distinguish this tool from the many specialized calendar siblings such as get_dividend_calendar, get_ipo_calendar, or get_buyback. It also omits the required category parameter, which is central to what the tool actually returns.

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 pagination mechanics ('For later pages keep filters unchanged...') but never explains when to use this tool instead of a sibling calendar tool. There are no exclusions, no alternative names, and no context for choosing this endpoint over the specialized ones.

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