syslog_tail_tool

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

No annotations are provided, so the description bears full responsibility for behavioral disclosure. It only states 'return', implying read-only, but does not explicitly state that it is non-destructive, does not require special permissions, or how it orders results. There is no mention of default behavior (e.g., pagination, limiting) beyond the schema default, and no warning about potential performance implications.

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, clear sentence with no redundant words. It is appropriately brief for a tool that likely just needs a quick factual statement. Nothing could be removed without losing meaning.

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?

The tool is simple and has a full output schema, so the description does not need to explain return values. However, given the sibling tools (especially syslog_grep_tool and syslog_search_tool), the description lacks context on how this tool differs (e.g., no filtering, just tailing the latest entries). An agent selecting among siblings might need more guidance to pick the right one. This is a moderate gap.

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 schema description coverage is 100%, so the schema already documents all three parameters. The description adds minimal semantic value – 'one source' vaguely references the source parameter but does not clarify accepted formats or relationship between parameters. This meets the baseline for full schema coverage.

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 clear verb ('Return') and resource ('most recent entries for one source'), which is specific enough to understand the basic function. However, it does not differentiate from sibling tools like syslog_grep_tool or syslog_search_tool – there is no mention of filtering or specific use cases, so it could be confused with other tools that also return entries.

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?

No guidance is given on when to use this tool versus the five siblings. It does not mention that this is for quick viewing of the latest logs without search or filtering, nor does it exclude any scenarios. An agent would have to infer usage from the name and schema.

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