calculate_emergency_fund

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

No annotations are provided, so the description must disclose behavioral traits. It does not mention whether the operation is read-only, has side effects, requires authentication, or handles invalid inputs. The verb 'calculate' implies no state change, but this is not explicit.

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: two sentences, no wasted words, and immediately states the purpose. It is well-structured for quick parsing.

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 5 parameters, 0% schema coverage, and no annotations, the description does not fully equip the agent. It fails to explain what the tool returns (output schema exists) or how parameters like monthly_emis affect results. The user must rely on the schema alone, which lacks descriptions.

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 description coverage is 0%, yet the description only partially covers parameters (monthly_expenses, dependents, job_stability). It omits monthly_emis and existing_emergency_fund, leaving their roles unclear. Default values exist in the schema, but the description adds minimal help.

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's purpose: calculating emergency fund size (3-6 months of expenses). It specifies key adjustment factors (dependents, job stability), and the tool is distinct from siblings like calculate_contingency_fund, which may have a similar scope.

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. Notably, sibling calculate_contingency_fund exists, and the description does not differentiate them, leaving the agent unaware of which to choose.

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