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

No annotations are provided, so the description carries the full burden of behavioral disclosure. It does not explicitly state read-only semantics, permissions, error behavior, or whether the overview is computed fresh, though the 'Get' verb and counts framing imply a read operation. This is adequate but not rich behavioral transparency.

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?

A single sentence with no filler; the parenthetical clarification about counts grouped by type and status earns its place. The action verb is front-loaded, immediately telling the agent what will happen.

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?

With only one required parameter and an output schema present, the description plus schema is sufficient for an agent to invoke the tool correctly. It does not cover error cases or alternative selection, but for a simple read-only overview the missing detail is minor.

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%, with both api_key and project_id already described in the schema, so the baseline is 3. The description adds no parameter-specific detail beyond indicating that project_id identifies which project's overview to retrieve.

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 uses a specific verb ('Get'), a clear resource ('a project's resource overview'), and defines the output as 'counts grouped by resource type and status'. This differentiates it from siblings like get_project and list_project_resources.

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 implies the tool is for retrieving aggregate overview data, but it does not explicitly state when to prefer it over alternatives such as get_project or list_project_resources, nor does it provide exclusion criteria. The usage context must be inferred rather than stated.

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