camelot_timezone_scheduler

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

Annotations already declare idempotentHint=true and destructiveHint=false, and the description adds 'Local browser processing,' which tells the agent that computation happens client-side and implies no server-side side effects or auth requirements. It does not specify deeper behavioral details, but with annotations and an output schema this is adequate.

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 core purpose is front-loaded in the first clause, and the description is short. Minor issues: a doubled period ('teams..') and the 'Canonical URL' line are unnecessary for tool selection, so it is not perfectly clean.

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?

With only two optional parameters, a fully described input schema, an output schema, and annotations, the description plus schema provide enough for an agent to make a syntactically valid call. It leaves out details like accepted timezone ID formats and the exact meaning of 'optimal,' but those are minor for an optional-parameter tool.

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?

The input schema has 100% description coverage and documents both teamLocations and workingHoursRange with defaults and descriptions. The tool description adds no additional parameter-level meaning, so it stays at the baseline for well-covered schemas.

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 gives a concrete action ('Find optimal meeting windows') and a clear resource ('across distributed international teams'), so an agent can tell this is a scheduling/overlap tool rather than a pure timezone converter. It does not explicitly name sibling alternatives, so it misses the top bar by a bit.

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 implies the use case — distributed teams needing overlapping meeting times — but offers no explicit 'use when' guidance and does not contrast with the similarly named sibling camelot_timezone_converter. An agent must infer when this is the right tool.

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