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

With no annotations, the description carries full burden. It discloses the methodology (Pinnacle sharp line, vig removal, fair line derivation), sorting behavior, and exclusion of PrizePicks. This provides sufficient behavioral context for an agent.

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 at four sentences, well-structured with front-loading of key purpose. Every sentence adds value with no redundancy.

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 explains core behavior but lacks details on output format, pagination, or error handling. Given no output schema, the agent lacks complete context for interpreting results.

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 description coverage is 25% (only min_ev_pct described). While the description adds context about computing EV per book and outcome, it does not clarify the format or usage of the other parameters (sport_key, event_id, markets). It partially compensates but not fully.

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 cross-book +EV per outcome for an event, with specific methodology. It does not explicitly distinguish from sibling tools like propline_get_odds, but the tool name and description make the purpose clear.

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 provides no guidance on when to use this tool versus alternatives. It does not mention prerequisites, context, or exclusions beyond being a 'Pro-tier endpoint'.

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

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.

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.

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

No annotations are provided, so the description must fully disclose behavioral traits. It states the result is 'book-agnostic' and 'decoupled from any sportsbook's lines', and notes 'Free tier', but does not mention authentication needs, rate limits, or what happens if the event is not completed. The description is too sparse given the lack of annotations.

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 composed of two concise sentences with no filler. The first sentence defines the core purpose, and the second adds relevant examples. Every word contributes value.

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 has only two required parameters and no output schema or nested objects, the description provides a baseline understanding. However, it lacks details on return format, error conditions, or pagination. It is minimally complete for a simple tool but leaves gaps in behavioral 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 has two parameters (sport_key, event_id) with no description coverage (0%). The description does not elaborate on these parameters or their expected formats/values. While the description provides examples of returned stats, it adds no meaning to the parameters themselves.

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 returns 'book-agnostic raw box-score stats for a completed event', specifying the verb (implicitly 'get'), resource (raw box-score stats), and scope (per-player stats decoupled from sportsbook lines). It distinguishes from siblings like propline_get_event_results or propline_get_scores by emphasizing it provides per-player stats such as strikeouts, hits, points, etc.

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 mentions the tool is for 'completed event' and is on the 'Free tier', implying it should be used for finalized events. However, it does not explicitly state when not to use this tool or provide comparisons to sibling tools (e.g., propline_get_event_results). Usage context is implied but lacks exclusions or alternatives.

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

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

No annotations are provided, so the description carries the full burden. It discloses that the response includes a bookmakers[] array with up to 13 books, that coverage varies by sport, and how parameters affect behavior. It lacks details on authentication or rate limits, but the core behavior is well covered.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
