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

With no annotations provided, the description carries the full burden of behavioral disclosure. It successfully indicates this is a read operation (implied by 'Lists'), mentions pagination behavior, and describes the return format. However, it doesn't address potential limitations like rate limits, authentication requirements, or error conditions that would be helpful for a tool with no annotation coverage.

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 appropriately sized with four sentences that each serve a distinct purpose: stating the core function, listing parameters, suggesting use cases, and describing returns. It's front-loaded with the essential information. Minor redundancy exists in mentioning pagination twice ('with pagination support' and 'page' parameter).

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 read/list tool with no annotations and no output schema, the description does well by covering purpose, parameters, use cases, and return format. It provides enough context for the agent to understand what the tool does and when to use it. The main gap is the lack of output schema, but the description compensates by describing return values.

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?

Schema description coverage is 100%, so the schema already fully documents all three parameters. The description adds minimal value by explicitly calling out 'Required: teamId' and 'Optional: limit (100), page', but doesn't provide additional semantic context beyond what's in the schema descriptions. This meets the baseline for high schema coverage.

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 clearly states the specific action ('Lists all user groups') with the resource ('in a Lokalise team') and scope ('with pagination support'). It distinguishes from sibling tools like 'lokalise_get_usergroup' (singular retrieval) and 'lokalise_create_usergroup' (creation) by focusing on comprehensive listing.

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 provides clear context for when to use this tool ('to audit team organization, check group structure, or prepare group management operations'), which helps the agent understand appropriate scenarios. However, it doesn't explicitly mention when NOT to use it or name specific alternatives among the many sibling tools.

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