Syslog Tail Tool

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

readOnlyHint=true already tells the agent this is a safe read, so the description's main added value is the behavioral frame 'most recent entries' and the single-source scoping. It says nothing about ordering, whether severity filtering affects recency selection, or truncation behavior, but with annotations plus an output schema the bar is lower.

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 zero filler, exactly the right shape for a simple read tool. It is arguably undersized for the routing decision, but the sentence itself earns its place.

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?

With full schema coverage, annotations, and an output schema, the description needn't explain parameters or return shape. However, for a tool sitting among five syslog siblings, the absence of any routing guidance leaves a real gap an agent must close by guessing.

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 100%, so limit, source, and severity are already documented in the schema, which sets the baseline at 3. The description only echoes two of them ('most recent' implies limit, 'one source' restates source) without adding format or interaction semantics.

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?

States a specific verb and resource ('Return the most recent entries') scoped to 'one source', which distinguishes it implicitly from query-based siblings like syslog_search_tool and syslog_grep_tool. It never names those siblings, so the differentiation is left to inference rather than made explicit.

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 gives no when-to-use or when-not-to-use guidance and names none of the five sibling tools (search, grep, context, stats, sources). An agent must guess that 'tail' means 'show latest logs for a known source' versus searching across sources.

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