get_node_journal

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

With no annotations provided, the description must carry the full burden of behavioral disclosure. It does not mention any behavioral traits such as authentication needs, rate limits, or pagination behavior (startcursor is listed but not explained). The 'Read' verb implies non-destructive, but more detail is needed.

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 short and front-loaded with the purpose. It uses a clear docstring format. While concise, it could be more structured with separate sections for clarity.

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?

Although an output schema exists (reducing the need to describe return values), the description lacks guidance on usage patterns, limitations, or integration with other tools. Given the 5 parameters and no behavioral context, it is minimally complete.

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?

The description adds meaning to all 5 parameters beyond the input schema, which has 0% description coverage. It explains the node, lastentries, since, until, and startcursor fields. However, the explanations are minimal and lack details such as date/time format or cursor syntax.

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 verb 'Read' and the resource 'systemd journal entries from a node'. This unambiguously defines the tool's purpose and distinguishes it from sibling tools like get_node_syslog.

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 provides no guidance on when to use this tool versus alternatives (e.g., get_node_syslog, get_node_firewall_log). There is no mention of prerequisites, exclusions, or context for usage.

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