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

With no annotations, the description carries the burden of behavioral disclosure. It does disclose that the default is not silently injected and that omitted project/environment inherit workspace binding. However, it omits details on side effects, reversibility, or permissions. The non-injection clarification is valuable, but the description is not comprehensive given the absence of annotations.

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 two sentences with no redundancy. The first sentence states the purpose concisely, and the second adds a critical behavioral note. It is front-loaded and efficient.

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 4 parameters, 0% schema coverage, and no annotations, the description is incomplete. It lacks essential parameter semantics for alias and capability_key, provides no usage context versus clear_adapter_default, and does not mention the output schema. While it covers the non-injection behavior, significant gaps remain for an agent to correctly use the tool.

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 only mentions that project/environment inherit workspace binding, but it does not explain the 'alias' parameter or the 'capability_key' default. The alias is the core parameter, yet it's not defined, leaving agents with insufficient guidance to correctly fill parameters.

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 sets a route-compatible semantic alias preselected for future image.generate.v1 work. It uses a specific verb ('set') and resource, and distinguishes from the sibling hydracept_clear_adapter_default. The phrase 'preselected' clarifies it's about defaults, making the purpose unambiguous.

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 does not mention when to use this tool versus alternatives. There is no guidance on when to set a default versus clear it, or when to use other adapter-related tools. The note about omitted project/environment inheriting workspace binding is a parameter behavior, not a usage directive, so no explicit when-to-use guidance is provided.

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