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

Beyond the readOnlyHint, the description discloses polling cadence, local-only execution, absence of rate limits, default exclusion of raw unmatched lines, and the security caveat about untrusted chat payloads. This is rich behavioral transparency with no contradiction.

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 compact and front-loaded with the primary purpose, then delivers constraints and caveats in distinct sentences. Every sentence earns its place; there is no filler or redundant restating of the tool name.

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 simple read-only tool with three optional parameters, the description covers source, freshness, filtering behavior, network behavior, and security. It could be slightly more complete by describing the output shape, but the event-type list and default filtering give an agent enough to invoke it correctly.

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 the schema already documents the three optional parameters and the enum values. The description adds no parameter-specific semantics beyond restating the event categories and the raw-line exclusion behavior, so it meets the baseline but does not exceed it.

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 uses a specific verb ('Return') and resource ('recently parsed events from the local Client.txt log'), and it enumerates the event categories: area transitions, level ups, deaths, trade whispers, player chat messages, and instance creation. This makes the tool's purpose unmistakable and distinguishable from the sibling tools.

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?

It gives clear context for when to use the tool: near-real-time local event retrieval with no network calls or rate limits, and raw unmatched lines are excluded unless explicitly requested. It does not explicitly name an alternative tool or state when not to use it, so it stops short of a 5.

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