Behavior2/5

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

No annotations are provided, so the description must carry the full burden of behavioral disclosure. It states that the tool clears the cache and forces a policy refresh, but it does not mention any side effects (e.g., temporary performance impact, potential authentication delays), prerequisites (e.g., administrative privileges), or whether the operation is reversible. The description is too brief to adequately inform an agent of behavioral traits.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness4/5

Is the description appropriately sized, front-loaded, and free of redundancy?

The description is a single sentence that is concise and front-loaded with the key action. It could be slightly improved by adding brief behavioral context, but it is not verbose. It earns its place without extra words.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness3/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

The tool is simple (clear cache on hosts) and has no output schema. The description covers the core action and purpose. However, it does not explain behavior when the 'force' flag is used or not, error handling (e.g., unreachable hosts), or expected outcome. For a tool with no annotation or output schema, the description is minimally adequate but has noticeable gaps.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters3/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

The input schema has 100% description coverage for both parameters: 'hosts' and 'force'. The tool description does not add any additional meaning beyond what the schema already provides. Baseline score of 3 is appropriate.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose5/5

Does the description clearly state what the tool does and how it differs from similar tools?

The description clearly states the action ('Clear SSSD cache') and the resource ('on one or more hosts'). It also explains the purpose ('to force policy refresh'). This verb-resource combination is specific and distinct from sibling tools, which are primarily for managing FreeIPA entities like users, groups, sudo rules, etc.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines4/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

The description implies when to use the tool: when you need to force a policy refresh on hosts. It does not explicitly state when not to use it or provide alternatives, but given the siblings, there is no close alternative for cache clearing. The usage context is clear enough for an agent.

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