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

Given no annotations, the description covers key behavioral traits: it is a mutation, has a dry-run mode, reads current config first, and returns a specific response on execution. It also mentions configuration requirements. Could be improved by detailing the dry-run output or error conditions.

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 extremely concise, using a structured label 'MUTATION (MEDIUM):' at the start, followed by two short sentences that capture essential information. No unnecessary words, and critical details are front-loaded.

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?

With an output schema present, the description appropriately focuses on input and behavior. It covers purpose, usage, dry-run/execute modes, return on execution, and configuration dependency. Minor gaps: no mention of error states or the dry-run output format, but acceptable given the output schema.

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%, so the schema already documents all parameters. The description adds context about the 'confirm' parameter's effect (dry-run vs execute) and the overall CAPTURE-or-declare pattern, but does not provide additional semantics for each parameter field.

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?

Clearly states 'update DNS resolver configuration on a PBS node' with a specific verb and resource. The abbreviation 'MUTATION' and distinction from a read tool (implied by 'pbs_node_dns_get' sibling) make the purpose unambiguous.

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?

Provides clear context for when to use the tool (to update DNS config) and explains the dry-run vs. execute behavior. However, it does not explicitly mention when not to use or list alternatives beyond the implied read sibling.

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