calculate_silver_nisab

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

No annotations are provided, so the description carries the full burden. It states the computational purpose but does not disclose safety traits (e.g., no side effects, no storage) or potential error handling. Since it's a simple read calculation, the lack of explicit safety details is acceptable but not exemplary.

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 sentence, 17 words, front-loaded with the purpose. Every word is necessary, and the structure is efficient with no 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?

Given no output schema, the description should indicate the return format. It states the result is a 'Zakat Nisab threshold' but does not specify whether it's a number, a string with currency, or a compound object. Edge cases or behavior with invalid inputs are not covered.

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%, but the description implicitly references both parameters: silver_price_per_gram (price input) and currency (threshold currency, default USD). It adds context that the calculation uses exactly 595 grams, but does not explain format, constraints, or acceptable ranges.

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 clearly states the tool returns the Zakat Nisab threshold based on 595 grams of silver at a given price. It specifies the verb 'Return', the resource 'Zakat Nisab threshold', and the exact calculation basis, distinguishing it from siblings like calculate_gold_nisab.

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 does not provide guidance on when to use this tool versus alternatives (e.g., calculate_gold_nisab or calculate_zakat). No explicit when-not-to-use or context about prerequisites is given, leaving the agent to infer applicability.

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