get_technical_indicators

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

With no annotations provided, the description carries full burden of behavioral disclosure. It only implies a read operation ('Retrieve') but provides no details on side effects, dependencies, or constraints such as required authentication or data freshness.

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 concise with one main sentence and organized Args/Returns sections. Minor redundancy: period default is stated in both the description and schema. But overall efficient.

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 the simple tool (2 params, output schema present), the description covers basic functionality. However, it lacks usage guidance and behavioral details, making it adequate but not fully complete for decision-making among many siblings.

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 adds meaningful explanations for both parameters: ticker as 'the symbol of the security' and period as 'time period for indicators (e.g., '6mo')' with default. This adds value beyond the schema's type/title fields.

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 verb 'Retrieve' and resource 'technical indicators for a given ticker and period'. It is unambiguous but does not differentiate from many sibling tools like get_quick_technical_indicators or get_support_resistance_levels.

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 alternatives. The description only states what it does, not when it is appropriate or when not to use it. With 60+ sibling tools, this is a significant omission.

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