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

With no annotations, the description bears the full burden. It states the tool returns health and workspace counts, which is the core behavior. No side effects or destructive actions are implied, which is accurate for a read-only health check. Could mention if authentication is needed, but not critical.

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?

Single sentence, directly states the function. No wasted words. Front-loaded and appropriately sized for a parameterless health check tool.

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 zero parameters, no annotations, and the presence of an output schema (assumed to document return structure), the description is complete enough. It tells the agent what the tool returns (health and workspace counts) and nothing more is needed.

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?

No parameters, and schema coverage is 100% (empty). The description adds no parameter info, but none is needed. Baseline 4 applies since schema already fully covers parameter semantics.

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?

Description clearly states it returns health and workspace counts. The verb 'Return' and resource 'ProtoGen health and workspace counts' is specific and distinct from sibling tools, which focus on CAD operations (create, describe, export, generate, manufacturing_plan).

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 explicit guidance on when to use this tool versus alternatives. However, the tool's purpose is self-evident as a health check, and sibling tools are functionally distinct (creating/exporting/describing CAD designs). Lacks explicit when-not or context triggers.

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