Test registry

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

Annotations indicate it is not read-only (readOnlyHint=false), not destructive (destructiveHint=false), and not idempotent (idempotentHint=false), but the description does not explain what side effects (if any) occur. It adds no context beyond the bare purpose, leaving agents unsure about safety or behavior.

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 concise, consisting of a single 5-word sentence that directly states the tool's purpose. However, it is arguably too terse, sacrificing completeness for brevity.

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 the absence of an output schema and the tool being an action (test), the description is incomplete. It does not explain what the return value indicates (e.g., success/failure, connectivity status), leaving agents with insufficient information.

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?

The input schema covers 100% of the parameter semantics with 'registryId' as 'Registry ID'. The description adds no additional meaning or context about the parameter's format, constraints, or usage.

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 'Test connectivity to a container registry' specifies a clear verb ('test') and resource ('connectivity to a container registry'), distinguishing it from siblings like 'arcane_registry_get' (get details) and 'arcane_registry_list' (list registries). However, it could be more precise about what 'test connectivity' entails.

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?

No guidance is provided on when to use this tool versus alternatives, such as 'arcane_registry_get' for detailed information or 'arcane_environment_test' for environment connectivity. There is no mention of when not to use it or prerequisites.

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