TDQS

C2.8/5.0

Behavior2/5

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

No annotations are provided, so the description carries the full burden. It states that the tool audits and synthesizes policies and returns a specific shape, but it does not disclose side effects such as writing an output policy file, whether it is read-only, or whether it requires network/sandbox permissions (despite many allow_* parameters). The return shape is helpful but insufficient for 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.

Conciseness4/5

Is the description appropriately sized, front-loaded, and free of redundancy?

Two sentences with no fluff, and the main purpose is front-loaded before the return shape. It is efficient, though slightly under-specified for the tool's complexity; still, for what it contains, the structure is tight.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness2/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

Given 9 parameters, zero parameter documentation, no usage guidance, and no annotations, the description is incomplete. It does state the return shape, but doesn't explain parameter semantics, invocation context, or side effects. An agent would need to guess how to correctly call this tool for a meaningful audit.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters1/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema description coverage is 0% and the description does not explain any of the 9 parameters. It doesn't mention that 'path' is required, what 'output_policy_file' controls, or what the 'allow_*' booleans mean. The description adds no meaning beyond the raw schema titles.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose5/5

Does the description clearly state what the tool does and how it differs from similar tools?

The description names specific actions (audit cloud SDK calls, inspect Terraform HCL2 for wildcards, synthesize least-privilege IAM policies) and a clear resource domain (IAM). This is detailed enough that an agent can distinguish it from generic siblings like rush_security or rush_iac without opening the schema.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines2/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

The description gives no guidance on when to choose this tool over alternatives, no prerequisites, and no exclusions. It merely states the purpose; the agent must infer when it is appropriate. There is no reference to sibling tools or contexts where this tool is or isn't preferred.

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