Api compliance assessments controls coverage retrieve

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

Annotations already declare readOnlyHint=true, idempotentHint=true, and destructiveHint=false, so safety is covered. The description adds only the scoping notion (coverage of controls for this assessment) and says nothing about what the coverage result contains or how it is computed, so it barely moves past the annotations.

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?

One short, front-loaded sentence with no filler. It is efficient, though the terseness leaves no room for the routing context an agent needs.

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 read tool with one param and no output schema, the minimum needed is present. But the description never explains what 'controls coverage' returns or how it relates to the sibling evidence_coverage endpoint, leaving a gap for selection.

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% for the single 'id' parameter. The description implies the id identifies a compliance assessment, which is a small but real clarification the schema does not provide; it does not state format or what happens on an invalid id.

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?

It names the resource (controls coverage) and the parent object (this compliance assessment), implying a read of coverage data. However the phrasing is a noun phrase with no explicit verb, and it does not clearly distinguish itself from near siblings like evidence_coverage_retrieve or the other assessment-scoped retrievers.

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?

There is no guidance on when to use this versus evidence_coverage_retrieve, requirements_list_retrieve, or other coverage/analysis endpoints. An agent must infer from the name that this is the controls-specific coverage view.

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