Set System Clock

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

Beyond annotations, the description explains idempotent behavior (returns already_set if values match) and supports dry-run, adding valuable context. No contradictions with annotations.

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?

Two concise, front-loaded sentences with no unnecessary information. Every sentence adds value.

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?

Description provides enough context for a setter tool with idempotent and dry-run features. It mentions the return value already_set, but lacks details on dependencies between parameters (e.g., if timezone changes affect stored values). Overall adequate.

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 baseline is 3. Description reemphasizes the parameters (date, time, timezone) but does not add new meaning beyond the schema descriptions.

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?

Description clearly states it sets the system date, time, and/or timezone on a MikroTik router, using a specific verb and resource. It does not explicitly distinguish from sibling get_system_clock, but the action is 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?

The description implies usage for setting clock values and mentions idempotency and dry-run, but does not provide explicit guidance on when to use this tool versus alternatives like get_system_clock for reading.

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