get_plus_di

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

No annotations provided. The description lacks behavioral details like data prerequisites, timeframe considerations, or computational requirements. A single sentence does not cover the necessary transparency for a technical indicator.

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?

Extremely concise (6 words) but at the cost of missing essential information. Conciseness is positive only when the content remains helpful.

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 tool's complexity (4 parameters, output schema), the description is severely incomplete. No explanation of return values, default behaviors, or interpretation cues is provided.

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. The description adds no information about parameters such as period, limit, or interval. Users get no help on what these mean for the Plus DI calculation.

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 'Plus Directional Indicator - measures upward trend strength' clearly identifies the tool's output and its purpose. It distinguishes from siblings like get_minus_di and get_dx by specifying it measures upward strength.

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 Plus DI versus other directional indicators or technical analysis tools. With many sibling tools, explicit context is missing.

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