Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
No annotations are provided, so the description carries the full burden. 'Fetch' implies a read operation, but it doesn't disclose behavioral traits such as data freshness, rate limits, authentication needs, or what the return format looks like (e.g., date range, fields included). This leaves significant gaps for an agent to understand how to interact with it effectively.
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 extremely concise with just two words ('Fetch IPO calendar'), front-loaded with the key action and resource. There is no wasted language, making it efficient and easy to parse for an AI agent.
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 the complexity of financial data tools and the lack of annotations and output schema, the description is incomplete. It doesn't explain what the IPO calendar includes (e.g., dates, companies, status), how results are structured, or any limitations. For a tool in a server with many similar siblings, more context is needed to ensure proper usage.
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?
The tool has 0 parameters, and schema description coverage is 100%, so there are no parameters to document. The description doesn't need to add parameter semantics, and it correctly avoids mentioning any. A baseline of 4 is appropriate as it doesn't mislead or omit necessary parameter information.
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 'Fetch IPO calendar' clearly states the action (fetch) and resource (IPO calendar), providing a specific purpose. However, it doesn't distinguish this tool from sibling tools like 'earnings_calendar' or 'company_earnings', which also fetch calendar data, so it misses full differentiation.
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 provides no guidance on when to use this tool versus alternatives. With many sibling tools related to calendars and financial data (e.g., 'earnings_calendar', 'company_earnings'), there is no indication of context, prerequisites, or exclusions for usage.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
