get_month_calendar

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

No annotations are provided, so the description carries the burden. It discloses the default-parameter behavior (current season), which is useful, but says nothing about whether this is a read-only operation, rate limits, or auth requirements. The 'get_' prefix and the existence of an output schema imply a read, but this is left to inference.

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 efficient sentence that front-loads the resource and scope before the default-behavior clause. No filler, though it is terse enough to leave adjacent questions unanswered.

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 values need not be described. The description covers scope and default but omits any routing against the six sibling tools, which is the main remaining ambiguity for an agent choosing among calendar/event retrievals.

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 0%, so the description must compensate. It adds the key semantic that omitting 'season' yields the current season, which the schema's bare 'default: null' does not convey, but it does not explain the enum values beyond what the schema lists.

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+resource: retrieve the full calendar for a season (28 days). The scope quantifier '(28 days)' is helpful, though the tool name 'get_month_calendar' conflicts with the description's 'season' framing, which could cause momentary confusion about the exact span.

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 documents the default behavior when 'season' is omitted (defaults to the current season), which is implied usage guidance. It does not, however, say when this tool should be used instead of siblings like get_week_birthdays or get_events_on_day.

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