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

Annotations already declare readOnlyHint=true, destructiveHint=false, and openWorldHint=true, so the safety profile is covered. The description adds a genuine behavioral fact beyond the annotations: it "Opens an interactive Dashboard widget in ChatGPT," telling the agent this call has a UI side effect rather than returning plain data.

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?

Two sentences, zero waste, and the most useful detail (what the snapshot contains) is front-loaded ahead of the widget-behavior note. 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?

With an output schema present, the description needn't explain return values, and with no parameters there is no input contract to document. For a zero-arg read tool, what it returns and the fact that it opens a widget is everything an agent needs.

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?

The tool takes zero parameters, so there is nothing for the description to disambiguate; the baseline for a parameterless tool is 4. The description correctly spends no space on parameter semantics.

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 states a specific verb and resource ("Get a snapshot of the connected account") and enumerates the exact payload: active projects with progress, upcoming deadlines, open tasks. This clearly distinguishes it from siblings like get_connected_account and get_recent_activities, which return different slices of account data.

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?

The summary nature of the content implies the tool is for an at-a-glance overview, but the description never states when to prefer it over get_connected_account, get_recent_activities, or list_tasks. Usage is inferable from the enumerated content but not explicitly guided, and no alternatives or exclusions are named.

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