get_service_logs

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

With no annotations, the description carries the behavioral burden. It clearly signals a read-only operation scoped to the newest entries for one service, but it does not disclose how the optional lines parameter affects results, unit name expectations, or possible failure modes. This is adequate but not rich.

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 a single, front-loaded sentence with no filler or redundant restatement of the tool name. It conveys the essential operation and scope economically.

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?

For a simple read-only tool with an output schema, the description plus schema covers the basic call. However, it omits usage routing and the effect of the optional lines parameter, so it is not fully complete for an agent that has not seen the sibling contexts.

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 description coverage is 0%, so the description must compensate. It clarifies that service means a systemd service and that the target is a Pi, but it does not explain the lines parameter, leaving its semantics to inference from the default value and parameter name.

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 states a specific verb (Read) and resource (newest journal entries for one systemd service on a Pi). This differentiates it from sibling tools like control_service and get_service_status, which target service control and status rather than journal output.

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?

It provides no when-to-use or when-not-to-use guidance, and names no alternative tool. The only usage signal is implicit in the purpose statement, so an agent cannot tell from the description when to prefer this over get_service_status or run_command.

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