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 correctly identifies this as a creation operation and mentions the return format ('Returns: Created group with assigned ID and configuration'), which is helpful. However, it doesn't disclose important behavioral aspects like required permissions, whether this operation is idempotent, rate limits, or error conditions that might occur.

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 efficiently structured with three sentences that each serve a distinct purpose: stating the tool's purpose, listing parameter requirements, and describing usage context and returns. It's appropriately sized without unnecessary elaboration, though the parameter listing could be slightly more integrated with the flow.

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 creation tool with 8 parameters and no annotations or output schema, the description provides adequate basic information about purpose, parameters, and returns. However, it lacks details about the mutation's side effects, error handling, or the structure of the returned group object, which would be helpful given the tool's complexity and the absence of structured output documentation.

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 schema description coverage is 100%, so the schema already documents all 8 parameters thoroughly. The description adds minimal value by listing which parameters are required vs. optional, but doesn't provide additional semantic context beyond what's in the schema. This meets the baseline expectation when schema coverage is complete.

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 ('Creates a new user group'), resource ('in a Lokalise team'), and purpose ('for organized permission management'). It distinguishes itself from sibling tools like 'lokalise_update_usergroup' (update) and 'lokalise_delete_usergroup' (delete) by focusing on creation.

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 establish role-based access control, organize team permissions, or set up project-specific groups'), which helps the agent understand appropriate scenarios. However, it doesn't explicitly state when NOT to use it or mention specific alternatives among the sibling tools.

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