list_deployment_manager_deployments

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

No annotations are provided, so the description must shoulder the burden of disclosing behavior. It only restates the action and return type, with no mention of permissions, pagination, or whether any side effects occur (even though it is read-only, this is not explicit). This falls short of informative 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?

The description is compact and well-structured with Args/Returns sections, matching a typical docstring. Every sentence provides necessary information, and there is no redundant 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 one-parameter list operation, the description covers the core purpose and return type. However, it omits practical context such as required permissions, potential pagination behavior, or how this listing fits with the broader Deployment Manager workflow. It is adequate but not comprehensive.

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 coverage is 0%, so the description is the sole source of parameter meaning. It explains that project_id is 'the ID of the GCP project to list deployments for', which adds clear purpose beyond the schema's bare 'Project Id'. However, it does not specify allowed formats or validation details.

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 ('List') and resource ('Deployment Manager deployments') within a defined scope ('in a GCP project'). It clearly distinguishes itself from sibling get_deployment_details, which focuses on a single deployment.

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 use when you need to enumerate deployments in a project, but it does not explicitly state when to choose this over alternatives, nor does it mention any exclusions or prerequisites. Guidance is only implicit.

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