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

Annotations already declare readOnlyHint=true, idempotentHint=true, and destructiveHint=false, covering the safety profile. The description's 'changes are made in the app' largely restates readOnly but does add a useful redirect pointer to settings_link page "security". No mention of permissions, scoping, or error behavior.

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?

Two tight sentences with no filler, and the substantive content is front-loaded before the redirect note. The settings_link reference is slightly awkward but earns its place by routing the agent.

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 no output schema, the description carries the burden of describing return content, and it does list the key fields. For a zero-parameter read tool this is largely sufficient, though it omits any note on scope or freshness.

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 zero parameters, so the baseline is 4. There is nothing for the description to disambiguate, and schema coverage is 100%.

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 enumerates exactly what the tool returns (2FA requirement, who hasn't enrolled, closed-conversation retention), so the agent knows the resource. However, it never states a verb+object like 'retrieves security settings' and does nothing to distinguish it from siblings such as get_workspace_settings or get_consent_settings.

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 explicit 'use this when' statement or comparison against sibling get_*_settings tools. The only guidance is the routing hint that changes are made elsewhere (settings_link page "security"), which implies this tool is read-only consultation rather than explicit usage criteria.

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