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

Annotations already declare readOnlyHint=true, idempotentHint=true, openWorldHint=false and destructiveHint=false, so the safety profile is fully covered. The description adds no behavioral context beyond the title text it repeats verbatim — nothing about return format, freshness of form data, or fallback behavior when a club is unknown.

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?

Very short and front-loaded: the resource is stated first, then three concrete example phrasings. The main flaw is duplicating the title verbatim in the first sentence, which is slack rather than added value.

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 read-only lookup with no output schema, the description does name the three things returned (position, recent form, next games), and the schema fully covers inputs. It is close to complete, though it omits any hint of the response shape or how 'recent form' is represented.

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 100%, so the schema fully documents team, q, league and country, including the 404 behavior for unsupported leagues and the deprecation note on q. The description contributes no additional parameter meaning, so the baseline 3 is appropriate.

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 (a club's league position, recent form, next games), which is more than a restatement of the name. It is clear what data is returned, though it does not distinguish itself from siblings like formguide_get_table, formguide_get_results or formguide_get_fixtures, which cover overlapping ground.

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?

Three example user questions ("how are Arsenal doing?", "what's Spurs' form?", "when do Birmingham play next?") imply the intended usage well. However it never states when to prefer this composite tool over formguide_get_fixtures/get_results/get_table, nor any conditions or exclusions, so routing against siblings is left to inference.

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