get_ratio_analysis

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

Annotations already establish readOnlyHint=true and openWorldHint=false. The description adds genuine behavioral context: it is Tally's own canned report, accessed via a plain Export Data request, and returns the native RATIONAME/value array shape unchanged. This goes beyond the annotations and explains what the agent will receive and the operational nature of the call.

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: it names the report and its scope in the first clause, then adds a useful parenthetical of contained ratios, followed by two short phrases about the request mechanism and return shape. Every sentence earns its place without redundancy.

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?

For a simple read-only report tool with two documented parameters, the description covers the essential purpose, scope, and return shape. The phrase 'native RATIONAME/value array shape as-is' is helpful but slightly vague, and there is no mention of empty results or behavior when no data exists for the date range. Still, it is sufficient for a low-complexity 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?

The input schema already fully documents both parameters (from, to) with descriptions and the DD-MM-YYYY format, so schema coverage is 100%. The description only restates that the report is for a date range, adding no new parameter-level meaning beyond what the schema provides.

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'), a clear resource ('Ratio Analysis report from TallyPrime'), and a date-range scope. The parenthetical list of ratios (Working Capital, Current Ratio, etc.) makes the report's content unambiguous and distinguishes it from sibling report tools like get_balance_sheet or get_profit_and_loss.

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 usage context is implied: use this tool when you need Tally's canned Ratio Analysis for a date range. However, it does not explicitly state when not to use it, nor does it name alternative tools for related financial reports (e.g., get_balance_sheet, get_cash_flow), so the agent must infer the decision boundary from the report name alone.

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