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

Annotations already declare destructiveHint=true, openWorldHint=true, and idempotentHint=true, so the safety profile is partially covered. But the description adds nothing about the significant hidden behaviors implied by the schema: external inference processing requiring explicit consent, a payment/invoice path, and the ability to chain from prior runs. For a destructive, open-world, externally-processing tool this is a real gap.

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 a single front-loaded sentence with no filler, which is structurally fine. However, the brevity is under-specification rather than disciplined economy: the sentence is a list of topic keywords and carries no operational information.

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 has 6 parameters, a nested inputs object, no output schema, and destructive/open-world annotations, yet the description is one topic sentence. An agent gets no sense of what the tool returns, what a run produces, or how the required consent and idempotency keys fit in. Substantially incomplete for this complexity.

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 only 67% and the description explains no parameters at all. Notably, sourceFields and sourceRunIds have no schema descriptions and are semantically non-obvious (they appear to reference prior run outputs), and the consent/payment semantics are undocumented in the description. It adds no meaning beyond what the schema already states.

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 single sentence names a specific verb (evaluate) and enumerates five concrete evaluation domains: lifecycle cost, warranty, compatibility, secure disposal, and supply continuity. Paired with the name 'it-hardware' this lets an agent distinguish it from siblings like it-software or telecom by subject matter, though the description itself never names or contrasts those siblings.

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?

There is no guidance on when to invoke this tool versus the many sibling category agents (it-software, telecom, indirect, mro) or versus workflow tools. No prerequisites, no exclusions, no indication of what input quality is expected before calling it. The agent must infer everything from the tool name.

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