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

Annotations already declare readOnlyHint, idempotentHint, destructiveHint=false and openWorldHint=false, so the safety and side-effect profile is fully covered. The description adds the inspected subject matter (workloads, storage, recent activity) but says nothing about auth needs, rate limits, or pagination beyond what annotations provide.

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 front-loaded sentence with no filler; the scope constraint follows immediately after the object of inspection. It is efficient, though it packs three resource types into a list without prioritizing them.

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 an output schema present, return values need not be described, and annotations cover the safety profile; the description adequately conveys what is inspected and for which scope. Only the lack of sibling differentiation and any access prerequisites leaves a minor gap.

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 both parameters are enumerated with defaults, so the schema carries the parameter burden. The description only restates the project/region scoping (and mislabels region as covered by 'synthetic region' implied), adding no format or selection guidance beyond the schema.

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?

States a specific verb (Inspect) and enumerates the resources covered (workloads, storage, recent activity), scoped to a single synthetic project and region. It is clear what the tool does, but it does not distinguish itself from siblings like inspect_identity_access or query_customer_export.

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 phrase 'for one synthetic project and region' implies the applicable scope, which is useful context, but there is no explicit when-to-use, when-not-to-use, or named alternative (e.g., inspect_identity_access) to route the agent. Usage is inferable rather than stated.

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