propline_get_event_results

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

No annotations provided, so description carries full burden. It discloses pro-tier endpoint behavior, free tier redaction of resolution and actual_value, and upgrade pointer. It implies read-only operation but does not explicitly state nondestructive nature or authentication requirements.

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?

Three sentences with front-loaded purpose, followed by distinctive feature and free tier note. Every sentence adds value without redundancy. Highly 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 no output schema, the description explains return structure (graded outcomes with marks and actual values) and free tier behavior. It is sufficient for a low-complexity tool with 2 params, though pagination and error handling are not mentioned.

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 2 parameters with 0% description coverage, and the tool description adds no detail about sport_key or event_id beyond their names. The purpose indirectly explains them but does not provide formats, examples, or constraints.

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 returns graded prop outcomes for completed events, specifying details like won/lost/push/void marks and actual stat values. It distinguishes itself from the-odds-api which does not grade props, making the purpose highly specific and differentiated.

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 indicates use for completed events and contrasts with the-odds-api, providing clear context. However, it does not explicitly suggest when to use this tool over other propline siblings (e.g., propline_get_event_ev), though the purpose is distinct enough.

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