tools_load_domain

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

No annotations provided, so description must fully disclose behavioral traits. It does not mention side effects, permissions, session-level impact, or whether loading is additive vs. replacement. Only states 'for the current MCP session' but no further details.

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?

Three sentences are concise and front-loaded with purpose, but missing parameter info and behavioral details means it is incomplete rather than efficiently written. Could be restructured to include parameter hints.

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?

Given 3 parameters, no output schema, and no annotations, the description should fully explain usage. It does not mention parameters, return values, or implications of loading a domain. Incomplete for effective tool invocation.

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 0% and description adds no information about any of the three parameters (domain, timeout, database). The required 'domain' parameter is not mentioned, making it impossible for an agent to understand how to invoke correctly from description alone.

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 states the tool registers a tool domain's full surface, and the use case distinguishes it from siblings like tools_list_domains. The verb 'register' and noun 'tool domain' are specific, though 'full surface' is slightly jargon.

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?

Explicitly says 'Use when you need tools beyond the essentials' and lists those essentials, providing clear context. Lacks explicit when-not-to-use or alternatives but adequate.

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