list_config_metadata

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

Annotations already declare readOnlyHint=true, idempotentHint=true, and destructiveHint=false, covering the safety profile. The description adds the endpoint but no further behavioral details (e.g., response shape, pagination, or side effects), which is acceptable for this simple GET though not richer than the annotations themselves.

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 short lines with no filler: purpose first, then the endpoint. Every word earns its place, making it an model of conciseness.

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?

For a zero-parameter read with an output schema present, the description is essentially complete. It would be improved by naming the sibling get_config_metadata_by_id to explain the list/get distinction, but that gap is more about usage guidance than core completeness.

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?

There are zero parameters, so the description has nothing to add beyond the empty input schema. The schema is trivially complete, and with no params the baseline of 4 is appropriate.

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 states it reads MetadataConfig and provides the exact endpoint. It clearly indicates a read operation, distinguishing it from create/update/delete siblings by naming and verb, though it doesn't explicitly contrast with get_config_metadata_by_id, leaving the list-vs-get distinction to the tool name.

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 given on when to use this tool versus get_config_metadata_by_id or other config list tools like list_config_host or list_config_naming. The description provides no context about scenarios, prerequisites, or exclusions, so an agent gets no help choosing among the many config siblings.

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