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

Annotations already declare readOnly/idempotent/non-destructive, so the bar is lower; the description adds real value by disclosing return contents (status, times, guest links, setup state, pagination) and precise date-filter semantics (from inclusive, to exclusive). The closing 'Read only' merely restates the annotation, but the rest is genuinely additive.

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?

Front-loads the core action and keeps to three dense sentences with almost no filler. Minor waste from restating 'Read only' and the truncated 'oriiion' token reads as a typo.

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?

No output schema exists, yet the description outlines the return shape and pagination behavior, and clarifies status and date semantics needed to call it correctly. Gaps remain around query/locale handling, but the essentials for a filtered-list tool are present.

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 carries the burden. It usefully explains the status enum values and the from/to boundary semantics, but leaves query (title search is only implied), limit, offset (pagination alluded to only), and locale unexplained despite 7 parameters.

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 (list the business's upcoming/past meetings) and its distinctive output (exact room IDs). It explicitly distinguishes itself from adjacent concepts ('not social posting dates or an external calendar'), though the garbled token 'oriiion' slightly muddies the resource name.

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?

Gives concrete routing rules: default upcoming, use history for catch-up requests, and all when searching by title. It stops short of naming sibling tools like get_meeting or get_meeting_catchup as explicit alternatives, so it is clear context without full alternative mapping.

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