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

Annotations already declare readOnlyHint=true, idempotentHint=true, destructiveHint=false and openWorldHint=false, so the safety profile is fully covered elsewhere. The description contributes beyond that by stating this is the *default* workspace for the connection and that role and granted scope are returned, which is essential because there is no output schema.

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 with no waste; the returned content is stated first and the usage cue second. 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 no input parameters, full annotation coverage and no output schema, the description carries the burden of describing return values — which it does at field level (workspace, role, scope). It stops short of saying what happens if no default workspace exists or how the data is shaped, a minor gap for a simple identity tool.

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 no parameters (parameter count 0, empty properties object), so there is nothing for the description to disambiguate. Baseline 4 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?

Uses a specific verb ('Return') with a specific resource ('the Emailit workspace this connection acts on by default') and enumerates what comes back: workspace, role, granted scope. It is clearly distinct from the many get-*/list-* siblings that target concrete resources like get-workspace-event or get-domain, though it never names an alternative.

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?

'Call it to confirm which account changes apply to' gives a concrete decision context for invoking it before mutating operations. There are no exclusions or named alternatives, but for a zero-parameter identity probe there is little ambiguity to resolve.

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