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

Annotations already indicate readOnlyHint and idempotentHint, so the safety profile is covered. The description adds useful behavioral context: team-scoped tokens get one team, while operator/OAuth tokens get all belonging teams, and it mentions the one-team limitation for free accounts. It does not describe response shape, but that is not required for a read-only list tool.

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?

The description is front-loaded with the core purpose and remains compact. The sentence about creating another workspace is slightly tangential to listing teams, but it provides relevant context about why the returned team set may be limited. Overall, no word is wasted.

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 zero-parameter, read-only, idempotent tool, the description is complete: it explains token-based visibility, points to the correct sibling for clients, and even notes team_id usage for downstream calls. There is no output schema, so lack of return-value detail is not a gap.

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 has zero parameters and an empty input schema, so schema coverage is trivially 100%. No parameter documentation is needed; the description correctly focuses on behavior and output semantics instead.

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 action ('see workspaces this token can act on') and resource ('teams'), and explicitly differentiates from list_clients in the final sentence. It clarifies token-dependent scope, leaving no ambiguity about what the tool returns.

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 description gives explicit when-to-use guidance based on token type, and directly names list_clients as the alternative for listing clients. It also notes workspace creation is dashboard-only, which helps an agent avoid attempting an unsupported action.

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