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

With no annotations provided, the description carries the full burden of behavioral disclosure. It only mentions that the tool 'returns description and relevant documentation snippets,' but does not state whether the operation is read-only, requires authentication, or how invalid component types are handled.

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 description is two sentences, front-loaded with the purpose, and every word is informative. It efficiently conveys both the core action and the output type without unnecessary 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?

For a simple one-parameter tool with an output schema, the description covers the main purpose and parameter semantics. The output schema presumably handles return structure details, so the description is reasonably complete, though it could mention potential limitations or edge cases.

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 schema has one parameter with no description, so the description's enumeration of valid component types (realm, client, user, role, provider, mapper) adds meaningful semantics. It does not specify whether the list is exhaustive or provide formatting details, but it significantly compensates for the 0% schema coverage.

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 clearly states the tool's purpose with a specific verb ('Explain') and resource ('Keycloak component'), listing six concrete examples (realm, client, user, role, provider, mapper). This distinguishes it from protocol-focused siblings, though it does not explicitly differentiate from the similarly named 'keycloak_explain' tool.

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?

The description provides no guidance on when to use this tool versus alternatives. It does not mention any prerequisites, exclusion criteria, or contrast with sibling tools like 'explain_keycloak_protocol' or 'keycloak_explain'.

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