get_inplay_odds_by_fixture_and_bookmaker

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

With no annotations provided, the description must fully disclose behavioral traits. It only states that it returns inplay odds, but does not mention pagination behavior, the effect of optional parameters like 'include' and 'filters', or any rate limits. It lacks details that would help an agent understand the tool's full behavior beyond the basic operation.

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 is front-loaded with key information. It efficiently conveys the core purpose without unnecessary words. While it could be slightly expanded with usage context, it is appropriately sized and well-structured.

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 8 parameters, no output schema, and many sibling tools, the description is insufficiently complete. It does not cover how to handle pagination (page/per_page), the purpose of optional parameters, or how results are structured. An agent would need to rely heavily on the schema alone, which is risky without further guidance.

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 100%, so the baseline is 3. The description adds no extra meaning beyond the schema's parameter descriptions. It does not clarify how 'include', 'select', or 'filters' interact, nor does it provide examples or additional context. It meets the minimum but does not enhance understanding.

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 'Get', the resource 'inplay odds', and the specific filters 'for a fixture from a specific bookmaker'. It effectively distinguishes itself from sibling tools like get_inplay_odds_by_fixture_and_market (which filters by market) and get_inplay_odds_by_fixture_id (which only filters by fixture). The purpose is unambiguous.

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 that for odds by market, one should use get_inplay_odds_by_fixture_and_market, or that it returns inplay odds specifically as opposed to prematch odds. There is no context on prerequisites or conditions for use.

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