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

No annotations are provided, so the description carries the burden of behavioral disclosure. It states this reads from the 'local calendar' but doesn't disclose return format, whether it's a read-only operation (implied by 'List'), pagination, or locale/timezone handling. It's adequate but not rich.

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?

A single, clear sentence with zero wasted words. The description efficiently conveys the tool's purpose and highlights the key date-based scoping without redundancy.

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 single-parameter read/list tool with 100% schema coverage, the description is reasonably complete. It lacks additional context like return format or timezone considerations, but given the tool's simplicity and the exhaustive schema, these are minor gaps.

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% for the single date parameter, including format (YYYY-MM-DD) and default (today). The description reinforces the parameter's role by stating events are for 'a specific date', adding modest value beyond the schema. Default-to-today behavior is a useful nuance.

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 uses a specific verb ('List') with a clear resource ('all events') and scope ('for a specific date from the local calendar'). It clearly distinguishes from the sibling create_event tool by focusing on reading/listing rather than 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 conveys that it reads local calendar events by date, which implicitly distinguishes it from create_event (the only sibling). However, it doesn't explicitly state when to use this vs alternatives or provide exclusions/edge conditions.

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