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

The annotations already disclose readOnlyHint, idempotentHint, and destructiveHint, so the safety profile is covered. The description adds only a purpose clause and no behavioral trait such as authentication requirements, response shape, or how team_id fallback works; that fallback behavior appears only in the parameter schema, not in the description.

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 a single sentence with no filler. The verb and resource are front-loaded, and the 'for financial calculations' clause adds useful domain context without redundancy.

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 simple, read-only tool with one well-documented optional parameter and strong annotations, the description is close to adequate. However, because there is no output schema, the description leaves the return shape implicit; an agent would benefit from knowing what settings are actually returned, such as rounding rules, currency, or calculation assumptions.

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 single optional parameter team_id is fully documented in the input schema, including UUID format, API-key vs OAuth behavior, and rejection of mismatched teams. Since schema description coverage is 100%, the description does not need to add parameter details, and the baseline of 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 states a specific verb ('Get'), a specific resource ('clarity team settings'), and a domain purpose ('for financial calculations'). This is enough to distinguish it from write tools like updateClarityTeamSettings and from other getters, though it does not explicitly contrast with sibling tools.

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 phrase 'for financial calculations' gives a weak implied use context, suggesting the tool is relevant when financial calculation settings are needed. However, it does not explicitly say when to use this tool instead of updateClarityTeamSettings, getTeam, or other related getters, and no exclusions or prerequisites are mentioned.

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