Api applied controls csf function retrieve

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

Annotations declare readOnlyHint=true, idempotentHint=true, destructiveHint=false, yet the description says the endpoint allows applied controls to be 'viewed or edited' — implying a write capability the annotations explicitly deny. It also omits that this is a zero-argument enumeration endpoint returning a fixed value list.

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 short sentence with no padding, so it is not verbose. But it spends its only clause on boilerplate ("viewed or edited") rather than front-loading the one fact an agent needs: what values this returns.

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 zero-param, no-output-schema retrieve tool, the description must explain what the response contains (a list of CSF function labels/keys). It does not, leaving the agent unable to know it is fetching an enumeration rather than control data.

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?

The tool takes 0 parameters, so there is nothing for the description to clarify; baseline 4 applies. No missing parameter meaning can be attributed to the description.

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 sentence restates the endpoint name in generic terms ("allows applied controls to be viewed or edited") without saying what this specific endpoint returns. Given ~40 sibling 'applied_controls_*' endpoints, the description gives no way to tell that this one returns the CSF function choice/enumeration values rather than control records.

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?

No guidance on when to use this endpoint versus applied_controls_retrieve, applied_controls_list, applied_controls_object_retrieve, or the parallel category/effort/priority/status enumeration endpoints. Nothing tells the agent this is the source of valid CSF function values.

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