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

With no annotations, the description carries the full burden; the 'get_' name and content imply a read-only lookup, and the list of audited items usefully discloses what the output covers. However, it says nothing about scope (own club vs whole federation), what happens when no matchday has been played, or whether findings can be empty.

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?

A single front-loaded sentence that moves from the source ('integrity round') to the concrete checks, with no filler. The clause 'nobody in two line-ups' is slightly colloquial but efficiently conveys the duplicate-registration check.

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-parameter, no-output-schema tool, the description does establish what the report examines, which is the main gap-filler. It still leaves unclear how results are presented and whose integrity is assessed, so an agent knows the subject but not the shape or scope of the answer.

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?

The tool takes zero parameters, so the schema-offers-nothing baseline applies; the description correctly implies the report is scoped automatically to the last matchday rather than requiring inputs. No parameter meaning is missing.

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 names a specific resource (the federation's integrity round findings) and enumerates the checks it contains (table vs results, suspensions, injuries, duplicate line-ups), which clearly separates it from siblings like get_table or get_match_report. It stops short of an explicit 'this is the audit report tool' framing, but an agent can infer the purpose confidently.

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 phrase 'after the last matchday' implies a timing context, but there is no explicit statement of when to call this versus inspecting get_table or get_match_report directly, nor any prerequisites. The agent is left to infer usage from the sentence alone.

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