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

The description says 'recording decisions' which implies a write operation, directly contradicting the annotation readOnlyHint=true. This is a serious inconsistency and provides misleading behavioral information. The price disclosure is noted but does not offset the contradiction.

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 brief, front-loaded with the core functionality, and contains only two sentences. However, the second sentence about pricing is arguably non-essential, slightly reducing efficiency but not hindering clarity.

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?

The tool has a minimal schema, no output schema, and no parameter descriptions. The description fails to explain the meaning of 'topic', expected input format, return value, or usage context. The read-only contradiction further undermines completeness, leaving the agent unable to use the tool correctly.

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 exactly one parameter 'topic' with no description (0% schema coverage). The tool description does not mention this parameter or explain how decisions, owners, and due dates are encoded in it, failing to compensate for the missing schema documentation.

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 the tool records decisions, owners, and due dates, which is a clear action and resource. The title 'Meeting Decision Log' reinforces the purpose. However, it does not explicitly differentiate it from sibling 'store' tools, though the decision-log focus is somewhat distinct.

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 guidance on when to use this tool versus alternatives. It only mentions functionality and pricing, leaving the agent without contextual decision-making information.

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