dcs_policy_settings

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

The annotations already declare readOnlyHint=true, and the "[READ]" prefix merely repeats that signal rather than adding context. The description says nothing about what "settings" comprise, whether the call fails for unknown policy_ids, or what shape the response takes, leaving the behavioral burden entirely on annotations and schema.

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 text is a single short sentence with zero filler and the read-only nature front-loaded. However, brevity here crosses into under-specification rather than disciplined conciseness, so it earns only a middling score.

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 tool with no output schema and an undocumented required identifier, the description leaves out nearly everything an agent needs: what settings are returned, how to source the ID, and how it differs from the other policy endpoints. Only the read-only nature is conveyed, and that is already in the annotations.

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 single parameter policy_id has 0% schema description coverage, so the description must compensate and does not. It never says where a policy_id comes from, whether it is required, or what happens if it is invalid, even though the schema marks it required.

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 gives a verb ("Read") and a resource ("policy settings"), but "policy settings" is essentially a restatement of the tool name dcs_policy_settings. It does not distinguish this from siblings like dcs_policy, dcs_policies, or dcs_policy_violations, so an agent cannot tell which of these returns settings versus full policy objects.

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 tool versus the many adjacent policy tools (dcs_policy, dcs_policies, dcs_policy_violations). No prerequisites, no exclusions, and no indication of what a caller gains here that they cannot get elsewhere.

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