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

With no annotations provided, the description carries full burden but discloses minimal behavioral traits. It mentions 'based on current trends' indicating the methodology, but fails to state whether this is read-only, what format the forecast returns (currency amount, time series, confidence intervals), or performance characteristics.

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?

Single sentence is front-loaded with the verb 'Predict' and contains no redundancy. However, given the lack of annotations and output schema, the extreme brevity contributes to under-specification rather than efficient communication.

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 forecasting tool with no output schema, the description fails to indicate what the forecast returns (total spend, daily breakdown, confidence ranges). Without annotations to indicate read-only status or safety, the description leaves critical behavioral context undocumented.

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 100%, establishing baseline 3. The description adds semantic context by referencing 'next N days' which maps to the 'days' parameter, but does not add format constraints, examples, or semantic relationships between parameters beyond what the schema already documents.

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 specific verb 'Predict' with clear resource 'cloud spending' and scope 'next N days based on current trends'. The predictive nature distinguishes it implicitly from historical analysis siblings like get_cost_summary, though it does not explicitly name alternatives.

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 explicit guidance on when to use this tool versus siblings like compare_periods or detect_anomalies. No prerequisites mentioned (e.g., whether historical data is required for the forecast).

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