gcloud_services_enable

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

No annotations are provided, so the description must fully disclose behavioral traits. It describes the action as enabling a service but doesn't state possible side effects (e.g., enabling billing, resource creation), whether it's reversible, or what happens if the service is already enabled. For a mutation tool with no annotations, this is a significant gap.

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 a single sentence that is short and front-loaded. It conveys the essential purpose without waste. However, given the behavioral gaps, it could be slightly more informative without losing 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?

Given the tool is a simple 2-parameter mutation with no output schema, the description should cover return behavior (e.g., success/failure signals, errors) and side effects. It doesn't explain, for example, whether it waits for the operation to complete or returns immediately, nor what the expected output is. This leaves the agent underinformed.

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 100%, so baseline is 3. The schema already documents both parameters well: 'service' (required, with example) and 'project' (optional, defaults to current). The description doesn't add semantic meaning beyond what the schema provides.

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 it enables a Google Cloud API or service for a project, using a specific verb ('Enable') and resource ('Google Cloud API or service'). It distinguishes from sibling tools like gcloud_services_list (listing) and other management tools, but doesn't explicitly differentiate from similar enable/disable tools if any existed.

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 usage when a service needs to be enabled, but provides no when-not-to-use guidance or alternatives. It doesn't mention prerequisites like required permissions or billing setup, nor does it reference sibling tools that might be more appropriate (e.g., gcloud_projects_list for checking project).

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