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

Annotations already declare readOnlyHint, idempotentHint, non-destructive, and closed-world, so the safety profile is fully covered. The description adds nothing behavioral beyond that: no matching semantics (substring vs exact for name, range semantics for height), no mention of the default result cap, and no statement about result ordering or pagination behavior.

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 with no wasted wording, which is structurally clean. For a tool with seven parameters and zero schema documentation, however, it is under-specified rather than appropriately concise, leaving real ambiguity unaddressed.

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?

An output schema exists, so return values need not be explained. Everything else is missing: no filter semantics, no limit/default behavior, no routing guidance among the many sibling search tools, and no handling of the empty-filter case, which for a 7-parameter query tool is a substantial gap.

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% across 7 parameters, so the description must compensate. It does map loosely onto name, position, height, and team, which helps, but it omits the limit parameter entirely and does not clarify that height is expressed as a min/max range, nor how team_id and team_name interact or whether name matching is partial.

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?

States a specific verb (search) and resource (players) and enumerates the searchable dimensions, which is far more than a restatement of the name. It does not distinguish itself from plausible siblings like filter_players or search_football_players, so an agent cannot tell from this text alone which one to pick.

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 when-to-use or when-not-to-use guidance, no mention of alternatives, and no indication of what happens when all filters are omitted (all players? error?). The agent is left to infer that this is the general-purpose player lookup, which is an assumption rather than guidance.

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