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

annotations already declare readOnlyHint=true, and the '[READ]' tag merely restates that. The description does add value by disclosing the returned content categories, but says nothing about auth requirements, cost, or freshness of the failed-login feed.

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 short blocks, front-loaded with the return contents and the priority hint. Every phrase (content list, 'lead with this', arg default) earns its place with no filler.

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?

There is no output schema, so the description appropriately enumerates the return shape itself. With a single optional parameter and a read-only annotation, nothing critical is missing, though the meaning of 'target' for IdP-scoped counts could be sharpened.

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 description coverage is 0% and the only field is a nullable target string, so the description carries the full burden. It explains that target is an IdP target name sourced from config and that omission selects the default, which the schema does not convey.

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?

States a specific verb ('one-shot summary') and enumerates exactly what is summarized: platform/realm, user/client/IdP counts, and the failed-login feed size. It is clearly the aggregate entry point versus the specialized sibling audits, though it never names a sibling to differentiate against.

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?

'Lead with this' is an explicit priority directive that tells the agent to call this before the specialized audits. It also explains the target arg's default behavior, but gives no when-not-to-use condition or explicit alternative routing.

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