save_calendar_settings

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

With no annotations, the description must disclose behavioral traits. It only includes '[mutation]' hinting at write operation, but lacks details on side effects, permissions, atomicity, or error behavior. For a global configuration change, more transparency is needed.

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 short but contains redundancy: the first sentence nearly repeats the title, and the second adds only 'global' and '[mutation]'. It could be more concise by merging.

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 the tool modifies global settings with a nested parameter and no output schema, the description should provide more context about expected behavior, return values, and potential impacts. It currently lacks essential completeness.

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 100% with descriptions for both parameters. However, the description adds no extra meaning beyond the schema, especially for the complex nested 'settings' object, whose internal structure remains unexplained.

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 tool saves global calendar settings, using a specific verb ('guardar') and resource ('configuración global del módulo de calendario'). It distinguishes from sibling tools like 'get_calendar_settings' and 'update_calendar' by emphasizing 'global' scope.

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. There is no mention of prerequisites, when not to use it, or related tools. The description is purely declarative.

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