domain_log

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

With no annotations provided, the description carries the full burden and it does disclose 'Read-only', which is a valuable behavioral guarantee. It also lists the content types (transfers, updates, registry messages). However, it does not disclose output format, ordering, or how far back 'recent' goes, leaving gaps in behavior transparency.

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?

Two short sentences with no filler; the core purpose is front-loaded and the read-only disclosure is stated immediately. Every sentence 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?

The tool is simple with only two parameters, and the schema covers required/optional fields. Still, without an output schema the description does not explain the return shape, and it leaves pagination behavior vague. The essentials are present, but some operational details are missing.

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 0%, so the description must compensate. It clarifies that the 'domain' parameter refers to the domain whose logs are returned, but it says nothing about 'pagelimit' or its effect. The schema already provides type, default, min, and max, so the description adds no semantic value for that parameter.

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 identifies the tool's purpose: returning recent log entries for a domain, specifically transfers, updates, and registry messages. This distinguishes it from sibling tools like domain_info (current status) and domain_list (enumerate domains).

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 implies this is the tool to use when you need recent activity logs for a domain, but it does not explicitly state when to use it versus alternatives, nor does it mention any exclusions or related tools. Usage context is implied rather than spelled out.

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