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

Annotations already declare readOnlyHint=true and openWorldHint=true, so the safety profile is covered. The description adds nothing beyond that: it does not say whether these are live or prematch odds, which markets/bookmakers are included, or whether unsupported events return empty results. Minimal added value over structured fields.

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?

A single short phrase with zero padding, front-loaded with the resource. It is efficient but borders on under-specification rather than true conciseness.

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 output schema exists so return values need not be described, and annotations cover safety, but for an odds/markets tool the description omits meaningful context such as live vs prematch scope, market coverage, or rate/coverage limitations. Against that reduced burden it still falls short of what an agent needs to invoke confidently.

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% and the single 'id' parameter is fully documented there with a format example, so the description has no gap to fill. Baseline 3 is appropriate; the description adds no extra meaning about the id beyond what the schema already states.

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?

Names the resource (SofaScore match betting markets) which does distinguish it from other sofascore_event_* siblings that cover stats, lineups, and incidents. However it is a noun fragment rather than a verb+resource statement of what the tool does, and it does not separate it from non-SofaScore odds tools like draftkings_odds or kalshi_market.

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?

No when-to-use guidance, no prerequisites (e.g. whether the event must be upcoming or live), and no mention of alternatives for the same data. The agent is left to infer usage entirely from the name.

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