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

Annotations already cover the safety profile (readOnlyHint=true, openWorldHint=false, destructiveHint=false), but the description adds real interpretive context: the 'unset' defaults for Profile and Friends, that Friends applies to EVERY friends-based system, that guests never get platform data, and that turning the bridge off deletes nothing. The last point is arguably for the write sibling but still useful framing. It does not describe the return format or shape.

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?

Content is front-loaded with the scoping constraint, and the enum explanations earn their place because there is no output schema. However the body is a dense run-on of nested parentheticals and semicolon clauses that is hard to scan for the one value the agent actually needs.

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, the description carries the burden of explaining return semantics, and it does so thoroughly for Profile, Friends, and Notifications, including default/unset behavior. Missing only minor items such as the response shape or whether this is title-scoped only.

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 coverage is 100% — the single title_id parameter is documented in the schema itself — so the description has no obligation and adds no syntax or format detail beyond it. Baseline 3 is appropriate when the schema does the heavy lifting.

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 precise verb and resource — GET ONLY the 'PlatformBridge' field of TitlePublicConfigurationModel — which scopes the read narrowly and distinguishes it from broad siblings like get_title_data. An agent can tell exactly what is returned without opening a schema.

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?

Usage is implied by the domain explanation (call this to inspect platform-bridge configuration), but there is no explicit when-to-use statement, no reference to the write counterpart save_platform_bridge, and no guidance on choosing between this and other get_* config readers. The agent must infer the routing.

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