game_center_matchmaking_rule_sets_get_instance

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

No annotations are provided, so the description carries the full behavioral burden, yet it discloses nothing about read-only nature, authentication, rate limits, or what the response contains. A bare route string is insufficient for a 9-parameter 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?

It is very short, but the value is wasted on duplicating the same route in parentheses, which adds zero information. Front-loaded yet content-free.

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 9-parameter tool with no annotations and no output schema, the description should explain the resource, include/fields semantics, and return behavior. Providing only the route leaves the agent with nothing beyond the schema.

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%, with each of the 9 parameters (id, include, limit_*, fields_*) clearly documented in the schema. Per the baseline rule, a 3 is appropriate even though the description adds no parameter meaning of its own.

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 is just the HTTP route restated twice, which essentially repeats the tool name without adding a verb or distinguishing scope. It signals a GET on a single rule-set resource, but only barely beyond what the name 'game_center_matchmaking_rule_sets_get_instance' already says.

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?

No guidance on when to use this vs the many sibling tools (get_collection, get_to_many_relationship, update_instance, etc.). The agent must infer everything from the name and schema alone.

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