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

The description mentions 'full replacement via PUT' but lacks details on what happens to optional fields (e.g., reset to defaults), permissions, side effects, or response format. No annotations exist to supplement.

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?

Single sentence, zero wasted words, directly conveys the core action and HTTP method.

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 8 parameters with no output schema. The description does not mention return values, behavior when optional fields are omitted, or prerequisite conditions. More detail is warranted for a full understanding.

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 coverage is 100% with descriptions for all 8 parameters. The description adds value by clarifying that this is a full replacement, implying all fields (especially optional ones) should be considered.

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 clearly states the action ('update'), resource ('DNS record'), and method ('full replacement via PUT'), effectively distinguishing it from sibling tools like create or delete.

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?

While it doesn't explicitly state when to use vs alternatives, the verb 'update' and phrase 'full replacement' imply modification of existing records, which is adequate given the distinct sibling names.

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