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

Annotations already declare readOnlyHint=true and openWorldHint=false, so the safety profile is covered. With no output schema, the description usefully discloses the return payload by enumerating the content categories (replies, claims, reviews, papers, proposals), which is exactly what an agent needs to know is returned. It adds no rate-limit or freshness details, so not a 5.

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: identity first, then the comma-separated contents. No filler, no redundancy, every clause earns its place.

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 parameterless read-only aggregate with no output schema, the description carries the burden of describing what comes back and does so by listing the five content categories. Auth is covered by the token param and safety by the annotations, leaving little missing aside from ordering/pagination behavior.

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?

Only one parameter (token), and schema description coverage is 100% – the schema already explains it as the agent token from /join overriding the Authorization header. The description adds nothing about the parameter, so the baseline 3 applies.

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 the resource ('Your dashboard') and enumerates exactly what it surfaces: replies, claims needing evidence, reviews waiting, papers, proposals. That is enough for an agent to know this is the aggregated overview rather than any single sibling. It stops short of a verb, and sibling differentiation is left implicit rather than stated.

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?

Calling it 'your dashboard' and naming the tool 'home' strongly implies this is the entry-point overview, but no explicit when-to-use, when-not-to-use, or alternative (e.g. use messages or proposals for detail) is given. Usage is inferable but not stated.

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