get_gcp_project_details

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

With no annotations, the description carries the full burden, but it only states that detailed information is returned. It does not disclose authentication requirements, error behavior for invalid project IDs, or any read-only guarantees beyond the verb 'get', which is insufficient for a tool in a GCP context.

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 and well-structured with a clear one-sentence purpose followed by Args/Returns sections. Every sentence earns its place, and there is no redundant or vague filler.

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 simple single-parameter get tool, the description is minimally adequate but leaves gaps. It does not describe the output structure (no output schema), nor does it connect to the broader tool context (e.g., how to obtain project IDs). More detail would be needed to fully inform the agent.

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 has 0% coverage, but the description explains that project_id is the ID of the GCP project, adding basic semantic meaning. However, it lacks format details or examples, and does not compensate fully for the schema's silence.

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 gets detailed information about a specific GCP project, using a specific verb and resource. It is easily distinguished from sibling list_gcp_projects by the verb 'get' vs 'list' and from other get_* tools by the resource type 'GCP project'.

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 provides no guidance on when to use this tool versus alternatives, nor does it mention required prerequisites like needing a project_id obtained from list_gcp_projects. Context is only implied by the parameter requirement, not explicitly stated.

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