check_for_updates

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

No annotations are provided, so the description carries full burden. It discloses that the operation is non-destructive and that it contacts a remote server. However, it does not mention potential network requirements, latency, or caching behavior. The behavioral insight is adequate but minimal.

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 concise sentences with no unnecessary words. It front-loads the purpose and immediately clarifies the read-only nature. Every sentence earns its place.

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?

Given the tool has no parameters and no output schema, the description covers the essential aspects: purpose, non-destructive behavior, and return value (installed and latest versions). It is complete enough for a simple check operation, though it could hint at the output format more precisely.

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, so schema coverage is 100%. The description adds no parameter details because none are needed. For zero-parameter tools, the baseline is 4, and the description properly explains the channel context ('current channel').

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 tool checks for RouterOS updates from the current channel by contacting MikroTik servers. It uses a specific verb ('check') and resource ('updates'), and no sibling tool appears to duplicate this functionality, so it is well-distinguished.

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 mentions that the tool does not change configuration, implying it is a read-only operation. However, it does not provide explicit guidance on when to use it (e.g., before upgrading) or when alternatives like system_packages might be more appropriate. The usage context is implied but not stated.

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