project_get_projects_by_id_resource_metadata

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

Annotations already declare readOnlyHint=true, idempotentHint=true, destructiveHint=false, and openWorldHint=true, so the safety profile is covered. The description adds little beyond the endpoint path and does not describe authentication needs, error behavior, what metadata is returned, or how missing projects are handled.

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 first two sentences are near-duplicates, and the endpoint path also duplicates the annotation title. The description could be reduced to one sentence without losing information, so multiple sentences do not earn their place.

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?

This is a simple read-by-id operation with complete parameter schema and annotations covering safety. The description is sufficient to call it, but without an output schema it does not explain what 'resource metadata' contains or what the response shape looks like.

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 100%, and the required id parameter and apiVersion parameter are fully documented in the schema. The description only repeats that lookup is by id, so it adds no meaningful semantics beyond the structured schema; baseline 3 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 a specific verb and resource: retrieves a project's resource metadata by id. It also gives the underlying endpoint, so the operation is identifiable. However, it does not distinguish this from nearby siblings such as iaas_get_project_resource_metadata or project_patch_projects_by_id_resource_metadata.

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 explains what the call does but gives no when-to-use guidance, prerequisites, or alternatives. An agent is left to infer that this is the GET variant for project resource metadata rather than one of the several sibling project or IaaS metadata tools.

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