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

With no annotations provided, the description carries the behavioral disclosure burden. It explains the default behavior, output content (matches, times, live/finished scores), and sorting behavior (major leagues first). It does not mention limits, freshness, or empty-result behavior, but these are minor for a simple read-only list tool.

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 two short sentences with no filler. The main function and default behavior are front-loaded, and the ordering note is concise and useful.

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 low-complexity tool with two optional, fully documented parameters and no output schema, the description adequately explains the return values and key behaviors. An agent can invoke it correctly with just this information.

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 both parameters are already documented with formats and examples. The description adds value by clarifying the default date behavior (today, Turkey time) and implying the scope of the lig filter, which goes beyond the raw schema.

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 states a clear, specific action: it returns football matches, times, and live/finished scores for a given day, defaulting to today in Turkey time. This clearly differentiates it from siblings such as mac_detay, puan_durumu, and takim_son_maclar, which serve different match/standings/team-history purposes.

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 implies its use for daily fixture and score queries and provides useful context such as default date and Turkey timezone, but it never explicitly tells an agent when to use this tool versus siblings or when not to use it. No alternatives or exclusion conditions are named.

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