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

With no annotations, the description carries the full burden. It usefully discloses that all timestamps are GMT/UTC, but says nothing about what the response contains beyond 'matches and scores', pagination, or freshness/refresh behavior — relevant for a live-score feed.

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?

Two short sentences, zero waste, with the core scoping ('currently live') front-loaded and the timezone caveat second. Every sentence earns its place.

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?

For a zero-required-parameter read lookup with fully documented schema, the definition covers scope, currency, and timestamp convention, and implying 'matches and scores' signals return content. Minor gap: no note on how 'live' is determined or refresh cadence, but nothing an agent strictly needs to invoke it correctly.

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 100% and both parameters are optional with descriptions in the schema, so the baseline is 3. The description contributes nothing about 'language' or 'notification_message' beyond what the schema already says.

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?

States a specific verb ('Get') and a specific resource scope ('currently live football matches and scores'), which an agent can distinguish from get_match (single match) and get_competition_day_fixtures (scheduled day). It does not explicitly name any sibling, so it stops short of a 5.

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 word 'currently live' implies the usage context, but the description never says when to prefer this over get_match or get_competition_day_fixtures, and gives no conditions or exclusions. Usage is inferred rather than stated.

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