get_expiry_dates

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

No annotations provided and description offers no behavioral traits (e.g., read-only, data source, rate limits). The description fails to disclose any implications beyond the bare purpose.

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?

Extremely concise single sentence that is front-loaded with the key action and resource. However, it lacks any structured breakdown, which would be helpful even in a short description.

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 output schema, no annotations, and 0% schema coverage, the description is insufficient. It omits return format, data shape, and any usage constraints, making it incomplete for a production use case.

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 description does not explain the 'symbol' parameter (format, examples, constraints). No added value beyond the schema listing it as required.

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 uses specific verb 'Get' and resource 'available expiry dates for an F&O symbol', clearly distinguishing it from siblings like get_option_chain or get_futures_data.

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 on when to use this tool versus alternatives; lacks exclusions or context that would help an agent decide between get_expiry_dates and related tools like get_option_chain.

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