dns_update_blocklists

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

With no annotations provided, the description carries the full burden. It states the action and frequency context but does not disclose potential side effects (e.g., service disruption, download time), return behavior, or any prerequisites. This is acceptable for a simple operation but leaves gaps.

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 two short sentences, front-loaded with the action. Every word contributes meaning, and there is no redundant information.

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?

This is a simple, zero-parameter tool with no output schema. The description explains the purpose and normal cadence, which is largely sufficient. Missing details about post-update confirmation or failure behavior are minor given the tool's simplicity.

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 are zero parameters, and the schema coverage is 100% vacuously. The description does not need to elaborate on parameter semantics, and the baseline of 4 applies.

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 uses a specific verb 'Force an immediate update' and clearly identifies the resource 'all configured block lists'. It distinguishes itself from sibling tools like dns_check_update by emphasizing the forced/immediate nature.

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 explains the normal 24-hour update cycle, implying this tool is for when an immediate update is needed. However, it does not explicitly state when not to use it or mention alternatives like dns_check_update for checking status.

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