C2.9/5.0
Behavior2/5

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

No annotations are provided, so the description carries the full burden of behavioral disclosure. It implies a read operation, but says nothing about rate limits, data freshness, auth requirements, or return format—gaps that matter for an odds feed that presumably updates frequently.

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

Conciseness4/5

Is the description appropriately sized, front-loaded, and free of redundancy?

A single efficient sentence with the resource and scope front-loaded. It is not padded, though its brevity borders on under-specification given the number of competing odds tools.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness2/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

For a read tool with 100% schema coverage and no output schema, the core is technically covered, but the description fails to position itself among many odds-related siblings or explain the relationship to the bookmaker-selection tools. An agent cannot confidently route to this tool over get_updated_odds or get_multi_odds.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters3/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema description coverage is 100%, so both eventId and bookmakers are already documented in the schema. The description's phrase 'selected bookmakers' adds a small hint linking bookmakers to the selection workflow, but no format or constraint detail beyond the schema.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose4/5

Does the description clearly state what the tool does and how it differs from similar tools?

States a clear verb and resource ('Get betting odds'), scoped to 'a specific event from selected bookmakers.' However, it does nothing to distinguish itself from close siblings like get_updated_odds, get_historical_odds, get_multi_odds, or get_dropping_odds, leaving the agent to infer which 'get odds' variant applies.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines2/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

The description gives no when-to-use context and names no alternatives, despite a crowded field of odds siblings (get_historical_odds, get_updated_odds, get_multi_odds). It also does not state whether calling select_bookmakers first is a prerequisite for the 'selected bookmakers' argument.

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