exercise_options_position

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

With no annotations, the description must cover behavioral disclosure. It reveals the primary effect (converting option to underlying asset), which is valuable, but it does not mention reversibility, cash requirements, expiration constraints, or whether it applies to both calls and puts. This is a moderate level of transparency.

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 a single, concise sentence that immediately states the action and result. Every word contributes value, and the structure is front-loaded with the key verb.

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?

The description is too brief for a financial action tool with no annotations or output schema. It does not clarify behavior for both call and put options (the phrase 'converting it into the underlying asset' is call-centric and may mislead for puts), nor does it mention prerequisites, return values, or side effects. This leaves significant gaps in context.

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 input schema already fully describes the only parameter ('Option contract symbol or ID.'), so schema coverage is 100%. The tool description adds no additional parameter meaning, hence baseline score of 3 is appropriate.

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 tool's function with a specific verb ('exercises') and resource ('held option contract'), and adds the key consequence ('converting it into the underlying asset'). This distinguishes it from siblings like 'do_not_exercise_options_position' and 'place_option_order'.

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?

The description implies the use case (exercise an option you hold) but does not explicitly explain when to use it versus alternatives, nor mention any prerequisites or exclusions. The sibling tool 'do_not_exercise_options_position' is not referenced, so guidance on when not to use this tool is absent.

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