Read system log

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

Annotations already declare readOnlyHint, idempotentHint, destructiveHint=false and openWorldHint, so the safety profile is covered. The description adds useful behavior by specifying that results are the *most recent* entries (an implicit newest-first ordering), but it says nothing about truncation, how many entries exist, or what a log entry contains.

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?

A single front-loaded sentence with no wasted clauses; the ordering constraint comes first and the optional filters follow it.

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 low-complexity read-only tool with full parameter documentation and complete annotation coverage, this is nearly sufficient. The only remaining gap is the return shape (fields per log entry), which matters somewhat since there is no output schema.

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% and all four parameters carry descriptions, so the schema does the heavy lifting. The description confirms that topics and text filtering are optional, but adds no syntax or semantics beyond what the schema already provides for limit, device, topics and contains.

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 and resource ("Read the most recent system log entries") and adds the filtering scope, so it is clearly the log-reading tool rather than the generic mikrotik_print or the system_overview sibling. It does not name a sibling explicitly, but the resource is distinctive enough to be told apart.

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 phrase "optionally filtered by topic or text" implies when the filters are appropriate, but there is no explicit guidance on when to choose this over mikrotik_print or the other read-only inspection tools, nor any stated prerequisites (device reachability, permissions).

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