updateCalendar

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

No annotations provided. Description does not disclose mutation behavior (e.g., partial vs full update), side effects, or authorization requirements. The agent lacks insight into what happens when updating.

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?

Two concise sentences with no unnecessary words. Front-loaded with core purpose and a key detail about ID format.

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?

Despite high parametric complexity (11 optional params), the description is minimal. Lacks explanation of update semantics (patch vs replace) and typical usage patterns. Incomplete for a mutation tool with many fields.

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%, baseline 3. Description adds the composite ID format detail, which is helpful. Other parameters are self-explanatory from schema names/descriptions, so no additional value.

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?

Explicitly states it updates a calendar item by ID, mentions v2 API, and provides ID format examples. Differentiates from create, finish, and unfinish siblings.

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?

Clear that this tool is for modifying existing calendar items. Does not explicitly state exclusions or alternatives, but context from sibling names (createCalendar, finishCalendar) is sufficient.

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