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

No annotations provided, so description carries full burden. It discloses the methodology (historical patterns) and max constraint (365 days), but omits output format, what happens with insufficient data, or whether results are cached/persisted.

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?

Two-sentence structure with purpose front-loaded. 'Args:' notation is slightly informal but efficient. No redundant text, though default value repeats schema information.

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 single parameter and lack of output schema, description covers core functionality but insufficient for full agent operation. Missing return value description and error conditions despite having siblings with potentially overlapping use cases.

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 has 0% description coverage. Description compensates partially by noting the max constraint (365) not present in schema, but only minimally explains semantics of horizon_days (doesn't clarify it represents the forecast time window into the future).

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?

Clear verb (Forecast) + resource (cash position) + methodology (historical transaction patterns). 'Forecast' implicitly distinguishes from sibling get_cash_position (current state), though explicit sibling differentiation would strengthen this further.

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 guidance on when to use this tool versus siblings like get_cash_position or analyze_working_capital. No mention of prerequisites for historical data or when forecasting is appropriate.

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