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

No annotations are supplied, so the description carries the full burden. It usefully discloses the return payload shape and the existence of a replay URL for deeper analysis, but says nothing about behavior on an unknown id, permissions, or whether the replay must be fetched separately via another 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?

Two tight sentences with the resource and its contents front-loaded and no filler. The replay sentence earns its place by pointing at a distinct follow-up capability, though it could be slightly tighter.

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?

With no output schema and a single trivial parameter, the description does most of the necessary work by enumerating the returned stat groups and mentioning the replay URL. The main remaining gap is that an agent still cannot tell where a valid match id comes from.

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% for the single required parameter `id`, and the description never explains that it is a match identifier, where to obtain one, or its format (e.g. from list_matches). The word "match" gives only the weakest hint at what the parameter represents.

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 uses a specific verb+resource ("One match") and enumerates the returned stat categories (fires, hits, damage, refused orders, sandbox health) plus the replay URL, which clearly separates it from list_matches. It stops short of naming that sibling explicitly, so the differentiation is implied rather than stated.

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?

"One match" implies single-record retrieval and the second sentence hints at a follow-up workflow (download the replay for tick-by-tick analysis), but there is no explicit when-to-use versus list_matches, no mention of prerequisites, and no guidance on obtaining a valid id. Usage must be inferred.

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