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

No annotations are provided, so the description carries full burden. It doesn't disclose behavioral traits such as whether this is a read-only operation, if it requires permissions, rate limits, or what the output looks like (e.g., text, JSON). The description only states the action without behavioral context.

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, efficient sentence in Spanish, front-loaded with the core action. It's appropriately sized for a simple tool, with no wasted words, though it could be slightly more specific to improve clarity without losing conciseness.

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?

Given no annotations and no output schema, the description is incomplete. It doesn't explain the return values (e.g., calendar format, error handling) or behavioral aspects. For a tool with 2 parameters and no structured output info, more context is needed to be fully helpful.

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 fully documents the parameters (year and month with defaults and constraints). The description adds no additional meaning beyond the schema, such as explaining cultural or format considerations. Baseline is 3 since the schema does the heavy lifting.

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 'Mostrar calendario de un mes específico' (Show calendar for a specific month) states the basic purpose with a verb and resource, but it's vague about what type of calendar (e.g., Gregorian, lunar) and format (e.g., grid, list). It doesn't distinguish from siblings like 'get_current_time' or 'days_between_dates', which could involve date-related operations.

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?

No guidance is provided on when to use this tool versus alternatives. The description doesn't mention prerequisites, exclusions, or compare to sibling tools (e.g., 'get_current_time' for current date info). Usage is implied only by the name and description, with no explicit context.

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