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

No annotations are present, so the description carries the full burden. It discloses the core behavior (reporting the connection's account and teams) but does not explicitly state that it is read-only, what authentication context is required, or how errors are handled. For a whoami-style operation the essential behavior is stated, but additional guarantees would help.

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 that states the output in a compact phrase. Every word earns its place, with no extraneous detail or repetition of the tool name.

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 or annotations, the description provides the essential information (account and teams), which is enough to select and call a parameterless identity tool. It stops short of describing the response format or team representation, but that is not critical for invocation.

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 input schema has zero parameters, and the description adds no parameter details because none are needed. Per the baseline for zero-parameter tools, this dimension is satisfying.

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 what the tool provides: the Donelane account and the teams it belongs to. Though it lacks an explicit verb like 'returns', the noun phrase clearly identifies the resource, and it is distinct from sibling tools list_dones and post_done, which operate on dones rather than identity.

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?

There is no explicit guidance on when to use this tool versus list_dones or post_done. The description implies the scenario (needing connection identity and team membership), but an agent must infer it. No alternatives or exclusions are mentioned.

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