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

The annotations already declare readOnlyHint=false and destructiveHint=false. The description adds useful behavioral context by stating that the tool snapshots current scorecard and rocks and freezes the agenda at meeting time. However, it does not cover permissions, idempotency, or what happens if the meeting was already started, so it remains only partially transparent.

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 description is a single, front-loaded sentence with no wasted words. It efficiently conveys the tool's action and the key side effect.

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 tool with annotations and no output schema, the description covers the core action and key side effect. However, it leaves the sole parameter undocumented and does not mention return behavior or error conditions, so it is adequate but not fully complete.

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 schema has one parameter, meeting_id, with 0% description coverage. The description never mentions meeting_id or explains what meeting identifier must be supplied. The schema supplies a UUID format and pattern, but the description does not compensate for the missing parameter semantics.

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 specific verb and resource: 'Start a Delta Meeting.' It also adds the core effect of snapshotting scorecard and rocks. It does not explicitly distinguish this from the sibling 'create_meeting' tool, 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 description provides no explicit guidance on when to use this tool versus alternatives. The presence of sibling tools like 'create_meeting' and 'end_meeting' makes this gap notable; the description does not say when starting is appropriate or what prerequisites exist.

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