get_income_statement_tool

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

With no annotations, the description must convey behavioral traits. It only states 'retrieve', implying read-only, but does not disclose data freshness, scope, or any side effects. This is insufficient for a tool with no annotation coverage.

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 very short, consisting of one sentence and a parameter bullet. While concise, it lacks clear structure and separates the parameter description as a sub-bullet, which is acceptable but not exemplary.

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 that an output schema exists, the description need not detail return values. However, it omits context such as time period (e.g., quarterly vs annual) and currency, which are typical for income statements. The description is minimally complete for a simple tool but could be more informative.

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 schema has 0% description coverage, so the description must compensate. It describes the 'company' parameter as 'The name of the company', but does not specify acceptable formats (e.g., ticker, full name) or provide examples. This adds minimal meaning beyond the schema.

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 it retrieves an income statement for a specified company, using the specific verb 'retrieve' and resource 'income statement'. However, it does not differentiate from sibling tools like get_balance_sheet_tool or get_cashflow_statement_tool, which are also financial statements.

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 is provided on when to use this tool versus the siblings. There is no mention of prerequisites, such as company identifier format, or any exclusions.

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