get_fii_dii_data

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

No annotations are provided, so the description carries full burden. It states it gets data but does not disclose what is returned (e.g., single value, list, time period, data format) or any behavioral traits like rate limits or data freshness. For a tool with no annotations, more detail is needed.

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 a single, 15-word sentence that is front-loaded with the action and resource. Every word adds value, making it highly concise and efficient.

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 zero parameters, no output schema, and no annotations, the description is the only source of information. It is minimal but sufficient for a simple data retrieval tool. However, it lacks details about the output format or time scope, which could be important for correct 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 zero parameters and the schema is empty (100% coverage), so the description is the sole source of meaning. It clarifies that the data is about institutional investors and their buy/sell activity. A score of 4 is appropriate as baseline for no params, but it could be more precise about the metrics.

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 uses a specific verb 'Get' and clearly identifies the resource as 'FII (Foreign Institutional Investors) and DII (Domestic Institutional Investors) buy/sell data.' This uniquely defines the tool's purpose and distinguishes it from siblings like get_oi_data or market_overview.

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. It lacks context such as 'Use this for overall institutional flow data' or mention of prerequisites. The agent must infer usage from the name alone.

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