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

Annotations declare readOnlyHint=false, idempotentHint=false and destructiveHint=false, but the description adds the crucial non-obvious trait that nothing is persisted on the server or in a browser and the result is returned inline. It also discloses server-side behavior (current period selection, localized name/company loading, country calendar application), which the annotations cannot convey. It does not cover auth requirements or error behavior.

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?

Three front-loaded sentences that lead with the action and then the behavioral consequences; no filler or restatement of the name. Slightly dense in the second sentence but each clause carries information.

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?

An output schema exists, so return structure need not be described, and the description correctly focuses on side effects and generation behavior. It is close to complete for a demo-creation tool, with only secondary details (permissions, invalid country/region handling) absent.

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 coverage is 67%, so the schema already documents country, language, timezone and region examples. The description usefully ties behavior to parameters (timezone drives current period, language/country drive localized names, country drives the calendar), but the 'kind' enum (DEMO/EMPTY) is never explained, leaving a real gap.

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?

States a specific verb and resource ('Create a localized demonstration project') and notes it mirrors the Rotase API project-creation operation, which is more precise than the title alone. It does not, however, contrast itself with siblings such as rotase_validate_project or rotase_generate_schedule, which an agent must infer.

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 when-to-use or when-not-to-use guidance, and no sibling tool is named as an alternative. The mention that it 'can generate an initial schedule' hints at a relationship with rotase_generate_schedule but stops short of telling the agent which to pick.

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