get_service_journal

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

With no annotations provided, the description carries the full burden. It adds 'bounded' and 'fixed SSM document' as behavioral context, but does not explain output format, pagination, or prerequisites like SSM agent availability. As a read operation, it is not misleading.

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 focused sentence, front-loaded with the main verb and resource. Every word adds meaning, with no unnecessary repetition or filler.

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?

There is no output schema, and the description fails to specify the return format, bounding behavior, or potential prerequisites (e.g., SSM document requirements). It also does not differentiate from sibling tools, leaving the agent with limited operational context.

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 does not directly explain any of the four parameters; 'bounded' loosely hints at minutes and maximum_results but does not clarify their meaning or the required parameters. This is a significant gap.

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 action ('Get') and the resource ('bounded nginx systemd journal'), which is specific and distinct from sibling tools that focus on health, metrics, errors, or status. The term 'bounded' also adds scope.

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 context implies usage is for retrieving nginx journal logs, but it does not explicitly state when to use this tool versus alternatives, nor does it mention any exclusions. It relies on the tool's name and sibling set for differentiation.

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