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

With no annotations, the description carries full burden and it delivers the single most important fact for a preview tool: 'Nothing changes', i.e. a guaranteed no-side-effect read. It also hints at the payload ('whether the agent is in this live meeting and what removing it does'). It does not cover error behavior or whether the meeting must be currently live.

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 short sentences, no filler, and the non-destructive guarantee is placed at the end as the takeaway. Every clause earns its place.

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 one-parameter preview with no annotations and no output schema, the description adequately covers intent and safety, and gives a rough sense of what is returned. Only the parameter provenance and not-found behavior are left unaddressed.

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% and the description says nothing about meeting_id — where to obtain it, whether historical meetings are accepted, or what the 'live' constraint implies. For a single identifier parameter this is inferable, but the description does not compensate for the coverage gap.

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 states a concrete, verifiable purpose: check whether the agent is present in a given live meeting and preview the effect of removing it. The name's 'preview_' prefix plus 'Nothing changes' makes it distinguishable from remove_agent_from_meeting, though that sibling is never named explicitly.

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?

Use is implied (this is the dry-run step before an actual removal) but never stated. There is no explicit instruction to call this before remove_agent_from_meeting, and no guidance on what to do if the agent is not in the meeting.

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