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

With no annotations, the description carries the behavioral burden and it does state meaningful traits: the 'official matches only' constraint, the 5-match limit, and the inclusion of the next match. No destructive behavior is implied, and for a simple read query this is sufficient; only edge-case behavior (e.g., fewer than 5 matches, no next fixture) is left unspecified.

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?

One short Turkish sentence conveys the core behavior with no filler. It is front-loaded with the main resource (team's last 5 official matches) and the additional result (next match).

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 one-parameter read tool, the description covers the high-level behavior, but it is thin: no param guidance, no sibling routing, and no output-shape hints in the absence of an output schema. An agent could select the tool correctly, but would be guessing about input normalization and return structure.

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 0% and the only parameter, takim_adi, has no description. The text refers to 'a team' but does not specify expected name format, language, normalization, or examples, so the description adds almost no guidance beyond the parameter name itself.

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 exactly what the tool returns – a team's last 5 official match results and its next match – which clearly distinguishes it from siblings like bugunun_maclari (today's matches) and puan_durumu (standings). It lacks an explicit verb like 'gets' or 'returns', which prevents a 5, but the resource and scope are 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 intended use is implied: use when you need a specific team's recent official results or upcoming fixture. However, it gives no explicit when-to-use/when-not-to-use guidance and does not mention sibling tools or alternatives, so an agent must infer the decision.

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