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

Annotations already declare readOnlyHint=true, so the safety profile is covered structurally. The description adds the required permission scope ("requires meetings.read"), which is genuine value beyond annotations, but says nothing about return shape or behavior when the ID does not exist.

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 clauses with no filler, and the action is front-loaded ahead of the permission requirement. It is efficient, though it borders on under-specification rather than true density.

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 tool with readOnlyHint and no output schema, the definition covers the core action and the auth prerequisite. It omits what is returned and the not-found behavior, leaving a modest but real gap.

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?

There is one parameter with 0% schema description coverage, so the schema offers no meaning for "id" beyond its type. The description only implies identification by reading "one meeting" and never states that the parameter is the meeting identifier.

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 and resource ("Read one meeting"), and the singular "one" distinguishes it from the sibling list_meetings. It does not explicitly differentiate from get_meeting_result or get_meeting_type, so it falls short of a 5.

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 phrase "Read one meeting" implies the tool is for retrieving a single record by identifier, which is adequate implied usage. There is no explicit when-to-use vs. when-not guidance or named alternatives such as list_meetings.

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