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

No annotations are supplied, so the description carries the full behavioral burden, yet it omits ordering, time window for "recent", pagination behavior, and whether results are capped by the limit parameter. An agent cannot tell the safety profile (read-only is implied by "list" but never stated) or the response shape.

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 single sentence is free of padding and front-loads the resource, which is good. But it is so compressed that it reads as a label rather than a specification, and the optional-filter clause is the only structural element.

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 simple two-parameter read tool this could be adequate, but with no annotations, no output schema, and 0% parameter coverage, the description should clarify what "recent" means, what limit does, and what is returned. None of that is present.

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 0%, so the description must compensate and only partly does: it explains that bot narrows results to one bot, but says nothing about limit, its semantics, default value, or maximum of 200. Half the parameters remain undocumented in both schema and description.

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?

"Recent matches, optionally for one bot" identifies the resource (matches) and the optional filter, which distinguishes it reasonably from the singular sibling get_match. However, the phrasing is a noun fragment with no explicit verb, and "recent" is never defined, leaving the purpose only partially pinned down.

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?

There is no guidance on when to use this versus get_match (single match) or the various get_ladder/get_cup tools, and no mention of whether a bot argument is required for meaningful results. The only hint at usage is the word "optionally", which signals the filter is not mandatory but stops short of any when/when-not rule.

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